After 2 years of having my PC (same configuration), yesterday the PC started to crash since today it didn't neither boot, giving me a 9.0 POST with no video signal.

My pc is:
Prescott 3ghz
abit ag8v-3rd eye
1 gb ram corsair xms
2 hd seagate barracuda s-ata RAID-0
sparkle 6600gt 128mb gddr3


Who can help me? Someone had the same problems? I hope I won't have to trash my motherboard and of-course, i won't loose all my files in the hd...
