Hi.
My PC's configuration:
- AMD Phenom II 955 X4 (stock cooler, no OC)
- 2x16 GiB RAM (9-9-9-24 @ 800MHz, DC)
- ASUS M4A88T-M
- HD7750 GPU
- Tagan 580W PSU
Everything were working correctly for some amount of time. Sometimes there was an issue with booting (blank screen) but after ~3rd reset the OS were started correctly.
Was ok until yesterday. Suddenly the Windows crashed and it wasn't able to start again. So I investigated if anything were warm/hot. I touched the radiator of CPU and it was hot. I was surprised because earlier wasn't doing anything load-stressing - just surfed the net via Chrome.
Okay, it happend sometimes on the other PCs, so I waited some time and tried to boot again.
Windows has started but after log-on many startup apps just simply crashed (Windows Error Reporting dialogs). In 1-2 minutes I saw colorful bars on my screen and OS crashed.
Resetting wasn't helpful but I noticed something weird. The MemoryOK red LED is often lighting. When the mobo is unable to boot, it lights.
Another weird thing - when I use the MemoryOK button to boot, it reboots a few times and then lets me into the BIOS where weird voltages for RAM appear. For example, instead of default 1.5V, it tuned to 1.71V. One time was 2.07 (!) but I didn't apply it. On 1.71V and even 1.57V it booted okay and I was able to start memtest86+. So far, everything works okay within all memory tests.
Of course i cleared the CMOS, tried booting, everything I came up with.
My question - is it a motherboard issue? Or something else?
PS. This configuration worked correctly for a months.
