Weird blobs on screen

[5ingh]

Hey,

Recently my system has started producing weird blobs on the screen while I'm playing a game, such as Alabtross. It only happens sometimes

I've checked the voltages in the BIOS..

the 3.3v vore is around 2.9-3.00v

and the -12v is around -12.85v

I haven't overclocked my PC at all. I have a 350w Antec PSU (Smartblue)..

Spec:

athlon 1800+
msi k7n-2 nf2 mb
512mb ddr dual chan
gf4
2x ide harddrives
2x 80mm fans

any ideas?

tia in advance

Nope nothing is overclocked. Its a old card (GF4 Ti), so I don't think it has a temp sensor. It is being cooled by a different cooler than the standard one.
