Motherboard is ASUS p4c800-e dlx. p4:firstname.lastname@example.org Video card: Radeon 9800 pro. RAn pcmark05 and it rebooted my computer. Went to bios settings to fine tune OC settings and pressed f-10. Computer restarted. said checksum error pressed f-1 to get to settings. Screen said please wait... after going blank. Then froze. I reset and no video feed. Went to use jumpers to clear cmos and it won't even boot up now.:dead: But when you set cmos to norm on the jumpers it won't give any video feed. Anyone out there that can help? It would be much appreciated.
