last year i updated my mobo bios to the beta version, then it corrupted the bios then beeps saying some errors, then i replaced the bios with the new one found on ebay with the latest updated firmware. then my pc work fine, then i overclocked it to about 4.5 ghz and run prime test for 12hrs then the results saying thet it is stable, some months pass by i noticed that my pc clock loose time, then i replaced the mobo battery a new one, days passed by, pc hangs at the post screen then i pressed the power and restart button to restart the system, then one day it hanged on the post and i restarted it and the dr debug 15 shows and now my pc just keeps on restarting and wont post.
right now i am breadboarding my pc to cpu only, dr debug shows 15 and restarts,
i swapped my ebay bios to the corrupted one and it beeps the error about corrupted bios a year ago
is it my cpu due to overclocking?
