Hi all,

need help please with my computer problem, here's the case;

My computer spec are:
- 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

this computer is about 6 years old, running Windows XP SP-3, and it's not overclocked.

In random time, while in idle time or gaming, the computer hang, no mouse cursor movement, no BSOD.
Therefore, usually i restarted by restart button on the computer.
When restarted and enter the boot screen, the cpu clock stated lower than it should ( 2,66 GHz ), about 1,4 GHz. and the BIOS said 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.
Then it run normally again. The hang of the computer happen 1x-3x at a time, with the "Load setup defaults" done only once.

What is the problem with this computer? please help. thanks.
 
Solution
May be the PSU is failing, if you have or could borrow one can check that, might also check the date, if it changes to a much earlier date, good chance your CMOS battery is dying

Thank you for replying.

Yes, the PSU is what i first thought as the problem source, but as i browse the web for further info, issue related to PSU is no power at all.
And the cmos battery has been replaced in november 2012 ( less than a year ) because the time keep changing.
i will try to clean the dust inside the computer first as other website member's suggest.
i will try every possible answer for this. thanks.
