Sounds to me like your having overheating issues, the first thing I would suggest is get some canned air and spray out your computer good. Spray out your vid card fan, cpu fan/heatsink as well as chipsets and motherboard. It could also be a ton of other things. How long have you been having these problems?

 

Other things to check or do

 

Virus scan

take memory out and put it back in, try just in a 2gig stick also

update video drivers (I like omega drivers) http://downloads.guru3d.com/ForceWare-Omega-Driver-v116925-Vista-download-1815.html

windows update (if you can)

run memtest86

 

things that can be going bad

 

1 video card

2 power supply

3 memory

4 motherboard (not likely)
