System reboots itself-video card problem?

[tinfoil]

My system reboots itself at different times and in different applications. It used to reboot during mechwarrior mercs but now even looking at email it does it. Also when starting the computer at times, the monitor screen gives me a "no sync" message. I physicaly reinstalled the video card and updated drivers in everything that did not make a diff. It seems to be getting worse. Case and cpu temps are good. Any ideas? Thinking of getting a new video card anyway.
Amd 2600+
512mb 2700 ram
msi K7n2 mobo
430 watt ps
Radeon 64mb ddr-updated to 7200 drivers " the problem"? card is about 3 yrs old

Could be your video card but I doubt it. You using the newest drivers you can for it? What brand is that memory? What are "good temps" for you?

HEHEEHEHE FUN! I had the same problem on multiple systems
here are some reasons I found my computers to be restarting for

1. Check vid card
2. check ram
3. check for infinate loop bug some vid cards have, although I think that is a GEFORCE thing
4. check for conflicting IRQs
5. Check for a faulty damadged mobo- I have had 3 like this all with the first version of the ks75a got new ones and that fixed the problem
