put finger to keyboard and composed:

I got this graphics card in my PC and the picture on the monitor
displays red dots and lines and sometimes goes away but returns
again. *I had to disable the driver for this card as Windows XP wont
boot in normal mode ie shows a black screen but in safe mode XP boots
but with red spots and lines and the picture goes purple if you try to
browse on the internet. *Is there any tests I can do with a
multimeter? *Or maybe get hold of a circuit diagram?

Those symptoms are consistent with a fault in the card's RAM. By
switching to a different driver, you are accessing difference areas of
memory. Also, if you select a lower refresh rate, this may mitigate
any timing issue.

Did you check the fan and capacitors on the card?

Please remove one 'i' from my address when replying by email.

I did check the capacitors and some were high with a capacitor meter
so I replaced them and the card worked for a few days but the symptoms
returned again. The power supply voltages going to the card seem
normal. Are there any tests I can do on the card?
