BIOS Problem

Dear Friends

My brother has a pretty old PC Pentium D with windows 7 installed. He has a 775-Dual-VSTA mobo from Asrock which as a PCIE x16 clocked at x4. Recently I noticed that his bus was being clocked to x1 instead, restarts usually fix the problem and usually don't. Now today he went to switch on his PC and bios read 3GB Ram when he only has 2GB Ram installed!!! and ofc pc can't boot, after a few resets, the monitor would not switch on.

What do you think is the problem?

I am suspecting a CMOS problem.

Need help pls

Try removing the CMOS battery, this make the BIOS reset.

I tried removing the CMOS battery.... all for nothing. I will try replacing the CMOS battery tomorrow. Ill post my results tomorrow

If that doesn't work, you might consider that the board "may" be going bad.

Just something to think about.

Good luck.

I got some good news!. After changing the CMOS battery and reseating, the RAM, and VGA the pc successfully booted into windows, and is currently running stable. Hope it remains this way :) though the only thing the vga still seems to be underclocked (running at x2 instead of x4) any ideas?

Thanks

try cleaning and reseating the vga card again.

Guys after 1 week of testing the PC, he has had no crashes, and the vga seems to have settled back to x4 every boot (as it should be).

Thanks all for your replies
