i have recently got a Nvidia 6600gt and i have several problems with it. Originally it crashed my pc after about an hour of playing games like BF:vietnam. i believe this was due to the fact i had a 230watt power supply when i needed a 300+, so i bought a new 330watt power unit.
after installing the power unit i have noticed that my graphics card has been getting very hot, so hot i can smell burning! Not a good sign i feel. Also when i went back on BF:vietnam some of the graphic flickered a bit and i seemed to have graphic lag over the main bases and other places where there was a lot of action.
specs;
Pentium 4, 3.0GHz
12GB hd
windows xp professional
1GB memory
330watts power supply
any help would be appreciated, cheers
