Memory instability
Memory instability
I'm dealing with frequent crashes in games and apps on Windows. Occasionally it's a complete system failure, other times just an app shutting down. I suspect one of my PC components is faulty, but I can't identify the exact part.
What I've tried so far:
- MemTest86: Sometimes reports errors, other times no issues.
- RAM: Swapped with another kit, problem continues.
- GPU: Changed to a different model, same issue persists.
- OCCT Power Test: Ran for 30 minutes, everything looked normal.
- BIOS: Still running version 1.93 beta.
PC specifications:
- CPU: Ryzen 7 7700
- RAM: Kingston KF560C30BBEK2-32 (4800 MHz)
- Motherboard: MSI B650M GAMING PLUS WIFI
- GPU: RTX 4070 Super
- Storage: 1 SSD M2, 2 SSDs SATA
- Power Supply: XPG Core Reactor II 750W
Next steps:
I'm considering taking my motherboard in for warranty, but it might be another component like the CPU or PSU. Unfortunately, local shops don't have AM5 parts available for testing. Anyone else had a similar experience or any advice on narrowing it down?
The PSU is brand new. On Reliability History, the applications that close always display as Stopped working. Exception code: c0000005. While playing games, I frequently encounter this memory-related error: 0xc0000005. Continuous use of Windows leads to file corruption and various other issues. I have performed multiple chdsk, DISM, and sfc operations. I have also reformatted the Windows system several times. Currently, I am identifying several errors: BlueScreen, 0xc000027b, 0xc0000005, 0xc000027b, 0xc0000409.
When memtest86 detects issues that prevent Windows from functioning properly, you need to resolve them for error-free operation. Disconnect the GPU and link to the IGP... then execute memtest86. If no assistance is available, disconnect all disks and run memtest86.
Is it working with memtest86 or Windows? If not, can you try using a PSU for testing?
It's on MemTest, so would you consider re-testing with the 1660 Super? The PSU cable isn't 12VHPWR, and the power draw is reduced.
