Re: Serious issue here, need help as i tried everything i can think of TWICE!
Word of advice
Never make decisions when you are angry
Now on the card thing.
Check your bios settings, AGP aperture to 128mb and fastwrites disabled. Check also your ram timings.
Check if the fan is working.
maybe the card is overheating, you can underclock it with rivatuner or coolbits. Lower to the least possible speed and try some games.
