w2k login graphics 'break'

[Caine]

G'day, recently I've made this system dual boot a number of OS's...but alas, I now have w2k crashing randomly.
The problem started when the computer was on during a power surge (this was around 3 months ago and i had a 'surge protector' on the power outlet). The computer was reset only to have the graphics of the w2k login break up and eventually crash the machine.
---went to bed---
The next morning the computer booted fine...but about a month later the same graphics problem happened and now it occurs nearly every time I try to login!
i.e. the screen goes strange colours in spots and the mouse puts black squares in places.
At first I thought my card had been 'fried', but if this was so wouldnt the problem happen in VGA mode as well? (which it doesn't)
I also run unix and linux flavors on this machine and they dont seem to have this problem...any suggestions?
Thanks

Hi Caine

I had this problem on several computers I sold, managed to solve it by increasing the voltage of the processor. I noticed that Asus CUSL2(-c) mainbords, and others too, default the voltage setting to 1.70, that's simply too low for 800Mhz processors I used. I set it to 1.85.

I only had this problem with Matrox G450 boards, I also use Asus v6800 videocards, but only if they want to play games, the video output is ok, but you can only watch it either on tv or on the monitor, and the desktop size falls back to 800*600
Seems that G450's require more power than the v6800's

As I noticed you overclocked your celeron quite a bit. Perhaps it would be wise to increase the voltage a notch, or clock it back a bit to 500mhz and see if it still occurs.

Succes
