At random times, while in idle time or gaming, the computer hangs, no mouse cursor movement, no BSOD.
I then use the restart button on the computer.
When restarted and entering the boot screen, the CPU clock is stated lower than it should (2,66 GHz), about 1,4 GHz. And the BIOS says that the setting in the BIOS was wrong.
So, I enter the BIOS and do "Load setup defaults", then I change again to my previous settings, which was the boot logo and the boot sequence only. After that, it runs normally again.
The hang of the computer happens 1x-3x at a time, with the "Load setup defaults" done only once.
My computer specs:
- CPU Intel Core2Duo E6750 (2,66 GHz )
- Motherboard Asus P5K
- Memory 4x Team 1GB pc 6400
- GPU Nvidia 9800 GT ( Pixelview brand )
- HDD WDC 1TB SATA
- Power Supply FSP 400W
- Asus DVD-RW SATA
The computer is about 6 years old, running Windows XP SP-3, and it's not overclocked.
What could be the problem with this computer?
