When the BIOS tries to boot the operating system, the PC shuts down (completely shut down! No power) automatically and tries to restart, and it keeps running. But if I enter the user interface of the BIOS then there is no problem in the PC, I checked the PSU, RAM and found no problem. But if I select a Hard drive / DVD / USB Drive to boot, then the PC goes into the loop. There is no bad sector in hard drive. One temporary solution I have found is to reset the BIOS by removing the battery or shortening the jumper pin. But it doesn't work occasionally. Any suggestions?
CMOS Battery Voltage Seems Okay to me 3.02 Volt
