Recently I had an issue with my computer suddenly restarting, maybe once every few days, not often.
Computer: 5 years old (but case,buttons, front fans are maybe 10 years old)
i5-7600K, GTX 1070, 16 GB ram, Win 10. OS on SSD .
I looked into what could be and did some obvious things:
1.Cleaned up the inside of dust
2. Started using a voltage stabilizer (Indonesia has blackouts and brownouts, this is something I should have been using before I know).
3.Switched the power socket so the PC wasn't sharing with lots of other devices
4. Upgraded the Motherboard BIOS (first time in 5 years).
5. Turned off Auto restart, sleep and various other things recommended online in the power settings.
6.Run memtest for a few hours to make sure Ram was OK - no errors.
7. Sfc/ check disk : no errors on hard drive.
The first two times it happened I didn't notice the connection but it just happen a third time and it was the same series of events, I am playing Dragon Age Inquisition, modded. The game CTDs, not unexpected when modding a game, then after about 4-5 min, when I am back in the desktop, after using Task manager to end the DAI running on my system the computer crashes (restarts/shutdowns).
From what I can see of my temp (after I restart the computer) they look fine, CPU cores are around 45 degrees, GPU at around the 50 degrees. Sure they may have been hotter 4 min before, but they are unlikely to drop 40-50c in a matter of minutes I think.
My fans do seem a bit old and slow though.
Could I need a new PSU? I have had this one for about 5 years, I think it is a 800 Gold.
What do you think guys?
