Hello:
My PC froze while burning DVD; unable to open task manager or move cusor. After 10 minutes, I pushed the RESTART button on the front panel: it started to reboot but then shut down. I pushed the START button and it rebooted, but then shut down. I started it again, hit DEL to go into BIOS and got "Unexpected voltage change..." message. I loaded the failsafe parameters and hit F10. Now it tries to boot, shuts down, tries to boot, shuts down ... etc. I had to turn the PSU off to get it to stop cycling.
Any suggestions?
