gfx card took a dump- plz recommend nvidia card

[nubishdubishbone]

hmm i suppose its marketing type of assurance to make ppl feel like they are doing their part with global green peace.

i wish i knew more so i could help myself, but have not the knowledge to fix this really fucking annoying problem with my pc that makes it lock-up after like 3-45 minutes of gaming...

my screen freezes at this point, i thought it was my gfx card burning out because there are afrtifacts present, sometimes it sounds like my audio froze as well with a tone from the ambience stuck at a point in the track. i replaced both my PSU and my Gfx card (as mentioned) but i still freeze, albeit later on during a session.

i cannot imagine that anew gfx card is not the answer, will anything else in my system exhibit that kind of behavior? it's got me thinking it could be my cpu or ram or board, im worried.

- Yup it has to be overheating something because a fan prolongs the timeframe it will work without problems. so i guess what i really want to ask is: is there anything ican do without equipment/ with a  pentium D processor (coretemp doesnt support mine), to maybe solve this issue? Thank you for being patient with me and for all you've done so far.
