So, I built this computer up 2 years ago. Since then, I've had numerous motherboard failures, and the computer has never been quite "right".
Whenever I overclock the CPU, I run Prime95 for 24+ consecutive hours, and do the same with Intel Burn Test, except for 12+ hours until I have no stability issues. After a few months of rock solid performance, the system starts giving all sorts of stability issues that nothing short of an OS reinstall seems to fix. So far I've had to reinstall the OS about 2-3 times a year at least due to this problem.
I started a thread on here near the end of last year to get help overclocking my i7 to be stable at 4.7GHz. It performed flawlessly with over 100 hours of stress testing all together, and I had no problems with it for months. Then, the GPU drivers started giving me severe problems with artifacting, flickering etc so I uninstalled the old drivers, used CCleaner and DriverSweeper to remove the traces of the old drivers, and after testing 6 different driver versions I gave up and reinstalled the OS (I set the CPU clocks to standard before the OS reinstall like I always do).
So recently I decided to load my old 4.7GHz stable BIOS settings (I saved the OC profile in the BIOS), and it gives nothing but problems. It runs 1.400V on average at that speed and while it's generally stable for most 12+ hour Prime95 runs, Intel Burn Test usually crashes after about a minute or 2, as does OCCT. I reduced the clock speed to 4.6GHz, and played around with the offset voltage so it's about 1.375V, and I still have the same problems.
I'm starting to get really sick of this temperamental build that only wants to work properly for a few months before this happens. I have just done a 8+ hour Memtest 86+ 4.20 run with no errors. It doesn't seem to give any problems at stock settings. If I had enough money I would shoot this computer or throw it into the sea and build a new one, but unfortunately I'm flat broke and won't be able to afford anything better than a dual core Pentium with onboard graphics if I do that.
When gaming the screen sometimes go blank, but the monitor light stays blue which means it's still getting some sort of signal (otherwise it turns orange-yellow colour). The event logs say the "system rebooted from a bugcheck" or "an I/O operation initiated by the Registry failed unrecoverably. The registry could not flush the hive (file):". Temperatures are not the problem since it still keeps crashing even on a cold morning when the hottest core is under 70°C.
I have included some screenshots of the BIOS to show the once stable 4.7GHz settings that are no longer stable.
I have updated the BIOS a few months ago to the latest version.
