How to Fix Frequent Crashes

Frequent PC crashes - whether Blue Screen of Death events, random restarts, or hard freezes - are one of the most disruptive issues a South African gamer or professional can face. Unlike slow performance, crashes often point to a specific failing component or driver, and identifying the right culprit saves significant time and money. The approach is methodical: start with software, move to settings, and only replace hardware once you've ruled out the cheaper fixes.

Quick Answer

Most PC crashes are caused by overheating, unstable RAM (especially when XMP/EXPO is enabled), driver conflicts, or a struggling power supply. Start by checking temperatures, running Windows Memory Diagnostic, and reviewing BSOD error codes in Event Viewer before touching any hardware.

🌡️ Check Temperatures First

Thermal throttling and shutdown is the most common cause of sudden crashes, especially in South African summer or in poorly ventilated cases. Download HWiNFO64 and run it in sensor-only mode during a game or heavy workload. CPU temperatures above 95°C or GPU temperatures above 90°C under sustained load indicate a thermal problem - either the cooling solution has failed, thermal paste has dried out, or case airflow is inadequate.

If temps look fine, check your PSU. An ageing or underpowered unit that sags under GPU load will cause immediate crashes. For a reliable PSU upgrade, browse Evetech's power supply range.

🖥️ Read the BSOD Error Code and Event Viewer

Windows records every Blue Screen crash in Event Viewer. Open it via Start → search "Event Viewer" → Windows Logs → System. Look for "Critical" entries timestamped at the crash time. BSOD stop codes like MEMORY_MANAGEMENT or PAGE_FAULT_IN_NONPAGED_AREA point to RAM. DRIVER_IRQL_NOT_LESS_OR_EQUAL usually indicates a driver problem. KERNEL_SECURITY_CHECK_FAILURE can be hardware or driver.

Run Windows Memory Diagnostic (search in Start) or the more thorough MemTest86 (bootable USB tool) to test your RAM sticks. If errors appear, try running with a single RAM stick, or disable XMP and run at default JEDEC speed to check if the XMP profile is unstable. Check current RAM options at Evetech if replacement is needed.

🔧 Update or Roll Back Drivers

GPU driver crashes are very common - particularly after a fresh driver update that introduced a regression. In Device Manager, right-click your GPU → Properties → Driver tab → Roll Back Driver to revert to the previous stable version. If rolling back isn't available, use DDU (Display Driver Uninstaller) in safe mode to do a full clean removal, then install a driver version known to be stable for your GPU.

Also check chipset drivers, which are updated separately from GPU drivers. Download the latest chipset driver from your motherboard manufacturer's support page and install it. Outdated chipset drivers can cause USB dropouts, storage disconnects, and intermittent crashes that are hard to attribute correctly.

❓ FAQ

Q: My PC crashes only when gaming - what does that indicate? A: Gaming pushes GPU, CPU, and PSU to higher load simultaneously. Crashes only under gaming load typically point to GPU overheating, an unstable GPU overclock, an inadequate PSU under load, or a driver issue. Test each variable individually.

Q: How do I know if my PSU is causing crashes? A: Use OCCT's PSU test to stress the power rails while monitoring voltages. The +12V rail should stay above 11.4V under load. If it drops further, the PSU is struggling. A failing PSU may also cause crashes without any BSOD - just an instant hard restart.

Q: Can a failing SSD cause PC crashes? A: Yes. A dying SSD causes read errors that Windows cannot handle gracefully, resulting in crashes or sudden reboots. Run CrystalDiskInfo to check SSD health - any "Caution" or "Bad" status on reallocated sectors means the drive should be replaced promptly. Browse SSDs at Evetech for replacement options.
