Greetings people of Cnet!
Yesterday ive decided its time to change the thermal paste on my cpu. Everything went smooth as i removed the old paste from both cpu and heatsink, i then took the cpu out of the socket to clean it all from the sides of it aswell (took my gpu out too to have more workspace in the case) after i was done, i put everything back in place and turned the system on. It posted with a message "bios settings were set to default" what could have caused this? i doubt that i somehow accidentaly managed to reset the cmos.
Today the system shut itself down while running prime 95, got stuck in a reboot cycle but it never booted up so i cut the power via psu button, opened the case, unplugged mobo + cpu power, re-seated all hardware including the cmos battery and the system booted up. I then ran 10 minutes of large FFTs in Prime95, 10 minutes of small FFts + memtest with no crashes / errors so far. It has crossed my mind that the PSU might be behind this, but in that case the hardware re-seating would take no effect, right? after some research i thought of a bad cmos battery but again, the bios only reseted itself once and it hasnt happened again ever since. (i rebooted the system many, many times since yesterday and even unplugged the power cord from the wall while it was on to simulate power outage)
So what could be the issue here? are these a dying motherboard symptoms? or perhaps just a poor contact between random piece of hardware and the mobo that got fixed after re-seating? I should also note that temperatures are not a issue incase of this build, cpu is hitting mid 50s while under 100% load, gpu high 50s to low 60s.
