6 Signs Your PC is About to Crash

Computer crashes can sincerely be frustrating – one moment your PC seems fine and then next it’s down and takes your files along with it.
However, as suddenly and seemingly unexpected computer crashes can be, they do give signs beforehand.
Jumia Travel, the leading online travel agency reveals 6 issues your PC is likely to have before it crashes.
Hardware Conflict
Sometimes, two components of a PC will try to consume the same resource or perform the same task. This creates a hardware conflict which manifests itself in unusual behavior during certain tasks. An example of this is an audio conflict that might disable audio in some programs, but not in others. These conflicts might not initially crash the system, but they tend to cause instability in the system which leads to a Blue Screen Of Death (BSOD) and/or a reboot.
To fix this, you should open the Windows’ Device Manager (you can find this in the Control Panel or via Windows Search) and check for hardware with a conflict. Hardware with a conflict typically appears with a yellow exclamation point next to it. You can re-install drivers for the malfunctioning hardware, or if you can’t stop the two components from interfering with it each other, try disabling one of them. If that still doesn’t work, then you probably have to physically remove one of the conflicting components (a technician should be able to help with this).
Random File or Program Corruption Issues
This is one of the classic signs of an imminent computer crash. This is when files that always worked suddenly don’t open, or only work on occasion. It may or may not be accompanied by an error message. To fix this, you should first ensure your anti-virus is running and up to date. Then you should run a full system scan for malware. A virus can sometimes be the cause of this issue. Another cause is a failing hard drive, so you should also check this for problems. If this doesn’t reveal the problem, look for hardware conflicts in the Windows Device Manager. A driver issue might be the cause.
Slow, Unreliable or Noisy Mechanical Hard Drive
Though Mechanical Hard Drives have become reliable over time, they still contain mechanical components that eventually wear out over time. So, the failure of these parts is a reality that users should prepare themselves for.
If programs are taking a long time to load, files don’t always open, or the sound of the driver has become louder when it’s working, then it’s likely the hard drive is wearing out. You can check the drive for errors, but please don’t consider yourself problem free if the result shows no errors. It is better to backup data to be safe.
Noisy System Fan
If your PC fan is suddenly louder than normal it’s because its internals are too warm. This can eventually lead to a crash and even hardware damage. SpeedFan, a PC monitoring tool, can help you investigate the problem and give you information on the temperatures your CPU and GPU are reporting. If the problem persists, you can take your PC to a technician to open up your desktop and clean out its fan, or replace the cooling pad with a new one.
Random Software and/or Adware Launches
If software launches without your permission, it is likely that your PC is a victim of malware. Often, the programs that appear are linked to one advertisement or the other, but Trojan can allow this avenue of attack. Also, if certain hardware like the webcam tends to activate without your consent, this is also part of the issue. This tampering eventually leads to problems with your PC as your PC is slammed with unwanted programs or its files are corrupted maliciously.
Solving this problem is not very easy, but you can remove the malwares and properly clean up your PC after an attack. An easier solution would be to make sure your files are backed up and then perform a clean re-install of Windows.
Occasional Boot Errors
When your system occasionally shows errors when you are booting your PC, it’s one of the signs to consider. The error message is usually along the lines of “boot device not found”. The Windows might eventually fail to reboot after the message, but might work at a later time or immediately if you press the reset button.
Occasional boot errors are generally a sign that something is wrong with your hard drive, or that your Windows installation has become corrupt. The common and usually the only way to fix this problem is to replace the drive and/ or re-install Windows.

PwC Reveals AI Scaling Gap Slows Africa’s Digital Transformation
African CEOs continue to trail their global counterparts in deploying artificial intelligence (AI) across business functions, as they remain stuck in experimental AI phases, finding it difficult to scale initiatives into enterprise-wide deployments.
![]()
This is one of the key findings of PwC’s 29th Global CEO Survey: Africa perspective. It found that more than 150 CEOs in Africa who participated in the survey demonstrate strong operational resilience and reinvention as they navigate currency fluctuations, political uncertainty, infrastructure constraints and supply chain disruptions.
It highlights a slower pace of digital transformation that could limit long-term competitiveness in Africa. While awareness and early adoption of AI are growing, enterprise-wide deployment remains limited, according to the survey.
The survey was conducted from 30 September to 10 November 2025 and surveyed 4 454 CEOs across 95 countries, including Africa.
Skills shortages, fragmented data governance, underdeveloped cloud infrastructure and risk-averse investment strategies are preventing African organisations from moving beyond pilot projects into full-scale AI-driven transformation, it finds.
“AI adoption in Africa is real, but scaling it across the enterprise remains a challenge,” says Christiaan Nel, AI Africa leader at PwC South Africa. “Caution must be balanced with urgency − those investing modestly today risk falling behind competitors scaling rapidly.”
Finding their way
Despite these challenges, African CEOs demonstrate strong operational resilience. The survey shows that 81% are optimistic about improving economic conditions, well above the global average of 65%, while 47% are confident about revenue growth over the next year.
The survey underscores that AI adoption highlights a broader reinvention gap. Only 41% of CEOs have clear AI roadmaps, and 37% formalised responsible AI processes. Skills availability remains a major barrier, with just 37% confident in sourcing and retaining talent for AI initiatives.
PwC research shows that when AI is implemented effectively, African companies experience tangible benefits: 56% report increased employee productivity, 53% gain executive time, 23% see revenue growth, and 25% achieve cost reductions. This confirms that AI can drive efficiency and transformation, but only if infrastructure, governance and investment keep pace, notes the study.
Vikas Sharma, Africa cyber leader at PwC Mauritius, explains: “The challenge is structural. Fragmented cloud environments, unclear data governance and underdeveloped cyber security make scaling AI difficult. Without these foundations, AI initiatives remain tactical rather than transformational.”
Beyond AI, CEOs are using technology to reinvent products, reach new customers and modernise operations. PwC highlights that cloud, analytics and digital frameworks are essential enablers for enterprise-wide AI, helping leaders move from experimentation to transformation.
Importantly, African organisations are using technology to augment rather than replace employees, maintaining workforce stability while improving productivity, it states.
Ambition versus execution
Although 55% of African CEOs consider innovation critical to strategy, only 13% are willing to take high risks in innovation projects.
Underlying capabilities reveal the challenge: just 16% operate dedicated innovation centres, 25% have processes to stop underperforming research and development, and 29% rapidly test ideas with customers.
Lullu Krugel, chief economist and ESG leader at PwC South Africa, adds: “The leaders who build enduring businesses protect their core while creating the future. Operational strength alone is not enough; transformation must be bolder.”
Investment restraint is evident: 59% of respondents report little to no change in IT spending, and only 8% are willing to make large investments despite geopolitical uncertainty. Confidence in acquisitions is lower than the global average, with 40% planning growth through acquisition, compared to 46% globally.
Yet diversification offers a competitive-edge. Nearly half of African CEOs have entered new sectors through services and product offerings in the past five years, generating 24% of revenue from these ventures. Technology leads planned expansion efforts at 17%, followed by real estate, retail and transport/logistics.
PwC concludes that Africa’s CEOs have the ambition and resilience but must move from operational excellence to strategic reinvention. This requires embracing risk as a catalyst for transformation, strengthening digital infrastructure, investing in change leadership and aligning AI adoption with enterprise-wide strategy.
Hannelie Gilmour, consulting and transformation platform leader at PwC South Africa, concludes: “Africa is uniquely positioned to leapfrog global peers. Tomorrow’s stability comes from today’s innovation. CEOs who act decisively will shape the continent’s next chapter.”

Firm Reviews the Evolution of Phishing Threats in 2025

A new Kaspersky review reveals how cybercriminals revived and refined phishing techniques to target individuals and businesses in 2025, including calendar-based attacks, voice message deceptions and sophisticated multi-factor authentication (MFA) bypass schemes.

The findings emphasise the critical need for user vigilance, employee training and advanced email protection solutions to counter these persistent threats moving forward.
Calendar-based phishing targets office workers
A tactic originally from the late 2010s, calendar-based phishing, has reemerged with a focus on B2B environments. Attackers send emails with calendar event invitations, often containing no body text, hiding malicious links in the event description.
When opened, the event auto-adds to the user’s calendar, with reminders urging them to click links leading to fake login pages, such as those mimicking Microsoft.
Previously aimed at Google Calendar users in mass campaigns, this method now targets office employees. Organisations should conduct regular phishing awareness training, such as simulated attack workshops, to teach employees to verify unexpected calendar invites.
Voice message phishing with CAPTCHA evasion
Phishers are deploying minimalist emails posing as voice message notifications, containing sparse text and a link to a basic landing page. Clicking the link triggers a chain of CAPTCHA verifications to bypass security bots, ultimately directing users to a fraudulent Google login page that validates email addresses and captures credentials.
This multi-layered deception highlights the need for employee training programmes, such as interactive modules on recognising suspicious links and advanced email server protection solutions like Kaspersky SecureMail, which detect and block such covert tactics.
MFA bypass via fake cloud service logins
These sophisticated phishing campaigns are targeting multi-factor authentication (MFA) by mimicking services like pCloud (a cloud storage provider that offers encrypted file storage, sharing and backup services).
These emails, disguised as neutral support follow-ups, lead to fake login pages on lookalike domains (e.g., pcloud.online). The pages interact with the real pCloud service via API, validating emails and prompting for OTP codes and passwords, granting attackers account access upon successful login.
To counter this, organisations should implement mandatory cybersecurity training and deploy email security solutions like Kaspersky Security for Mail Servers, which flags fraudulent domains and API-driven attacks.
“With phishing schemes growing more deceptive, Kaspersky urges users to treat unusual email attachments, like password-protected PDFs or QR codes, with caution and verify website URLs before entering any credentials.
“Organisations should adopt comprehensive training programmes, which includes real-world simulations and best practices for spotting phishing attempts. Additionally, deploying robust email server protection solutions ensures real-time detection and blocking of advanced phishing tactics,” comments Roman Dedenok, Anti-Spam Expert at Kaspersky.

NDPC Commits to Balancing Data Privacy, Protection Information

Nigerian Data Protection Commission (NDPC), has expressed its commitment to balance information around data privacy and protection.

Dr. Vincent Olatunji, national commissioner, NDPC, stated this in Abuja, at the National Data Privacy Summit with the theme, “Privacy in the Era of Emerging Technologies,” organised by the commission.
Olatunji said the NDPC, at the moment, was looking at balancing information around data privacy and protection.
“What we are doing is just to look at how to balance information around privacy and protection, which is really important, because as we are innovating, at the same time, we have to consider issues around privacy and protection,” he stated.
He added that the commission has been very bold in taking risks that would bring about growth.
“Our starting point is growing at a very alarming rate, and we are not afraid of anything. We can take risks. And that is why a lot is happening in Nigeria, and this is the level of clarity,” he explained.
In his address, Dr. Aminu Maida, executive vice chairman (EVC) of the Nigerian Communications Commission (NCC), stated that Internet of Things holds promise for Nigeria’s economy.
The EVC, who was represented by Abraham Oshadami, executive commissioner, Technical Services (ECTS), noted that, “in an era in which digital assets, Internet of Things, future digital computing and other transformative technologies are key, and both a cornerstone of building trust for the adoption and a prerequisite for sustainable progress.
“Emerging technologies hold immense promise for Nigeria’s grand economy, but they also introduce complex risks to personal and individual rights.
“So, balancing innovation through post-ethical safeguards and public trust is the first step to ensuring that global digital advancement benefits all Nigerians without compromising their privacy or their security,” he added.
“As we just heard from the Nigeria Police, telecom operators have a vast amount of sensitive historical information daily, including connectivity apps and collaboration on privacy, security, and number protection, both to their and their inheritors,” he said.
Dr. Bako Shurkuk, commissioner for Science, Technology and Innovation, Plateau State, who represented Caleb Mutfwang, Governor of Plateau State, said, emerging technologies can be harnessed to attain sustainable growth.
