Question PC crashes/freezes randomly

over 2 years old system, never had issue until about few months back where these random crashes started to occur. its mostly during playing games but had it happen during work or just browsing web. sometimes there is no crash for week or two, sometimes there are several crashes during single day.

what happens is, the computer either freezes and i have to do hard reset, or it just resets it self. sometimes after reset i am unable to boot, there is black screen, fans spin, leds on but no activity. to make computer boot, i need to pull memory stick out and put it back in and it will boot.
the store i bought the system from had me troubleshoot some items, all tested fine. at the end, he suggested to reinstall windows, but he said it would wipe all stuff i have installed. this is the last thing i want to do really as i have tons of programs i use for work installed, plugins, updates atc, which reinstalling all would be major pain. so before i do so, i wander if anyone could think of something else i could try?

he basically had me do memory test, test for cpu overheating, and graphic card test with furmark.

hi, i have replaced psu for the recommended one, unfortunately it didnt seem to help as the same issue persists? anything else i should be looking into?
 
what is AIO?
when i troubleshooted with the guy from ibuypower we checked cpu and gpu and it tested fine. according to him at least.
 
any other ideas on what to check? seems i did all the tests i could find recommendations online, either all checked out or the fix did not help.

I had the same issue a while back with a 980ti. Tried everything and everything came back fine. Including temps.

I wound up having to rma the graphics card. It was a bad card. Try taking the card out and running some games with onboard graphics and see if it crashes. OR if you can get your hands on a friends graphic card or a super cheap one to test with
 
how did you pinpoint it was the card in the end? is there a test to try? i did furmark but it was ok.
my crashes dont just happen with games, its Revit too and sometimes just plain internet browsing.
my system was working flawlessly for a year, i dont remember single crash from that time. i had to travel to Europe last winter and wasnt using computer for a few months. once i returned these odd crashes started happening.
anyway, i have older Nvidia card in another system i could swap and try maybe.
were your crashes random as well? after i replaced psu, i had few crashes and then not a single one for a month. now it started again crashing more often.
 
today i tried video card from my older desktop. the crashes are still happening, so i assume i can rule out graphic card. i am going to do the same with memory sticks from older computer.
