I have had a recurring issue with my PC, but the symptoms have changed over time.
Issue became more frequent after I changed the HDD to SSD. I had some similar issues before, but with less frequency.
Problem was that it would continuously reboot before entering BIOS.
Sometimes (maybe about 1/8) it would go through BIOS and then work fine, with no issues at all.
Other times (maybe 1/4) it would not reboot, but not go to BIOS either. There is no MB beep at all when this happens (fans and MB lights on, but no booting).
I went through the troubleshooting guide on this forum, and tested systematically with the most basic components, moving up.
CPU, HSF, PSU only (no mem or GPU) 8 short beeps & then reboot (although # beeps isnt always consistent)
CPU, HSF, PSU, MEM (no GPU) fans & lights on, no beeps
CPU, HSF, PSU, MEM, GPU: as above, no MB beeps
Now consistently it does not boot. It hasn't got through to BIOS since I started these tests.
I'm guessing its either PSU or MB. I will test with another mem stick, but don't have access to the other components to test them.
Do these symptoms suggest MB over PSU or vica versa?
