Hello and thank you for listening, My computer I built three years ago, the components are an msi x58a-gd45, 12gb cosair 1333 ram, an I7 bloomfield cpu, and an engxt 460.
now recently i have been playing more league on my desktop then my laptop cause of lag issues, but like a week ago my computer just oddly restarted, it kept doing it like once every so often, but now it just keeps restarting and i have no idea why, the only programs i have running are like league of legends, mumble, and maybe avg antivirus in the background, I have cleaned out my computer so i know it's not over heating, even putting new thermal paste on the heat sink.

I have no idea what it could be i have ran virus scans and cleaned registry errors, defragmentation, etc but i dont know how to find out the problem now. can someone please help me.
also its running windows 7

temps please.

also it may be helpful to run cpu and gpu stress tests to see if you get crashing there too.

psu is high enough wattage (i was worried about underwattage issues).

i wouldnt think heat would be an issue with a haf case. of course not applying thermal compound correctly could still cause an issue. this is why i want to know the cpu temp. if you can...give me an idle, an in game and then keep an eye on it and when the pc crashes give me a reading then too.

it wouldnt be a gpu overheat as it would just shut off the video for a few minutes but the rest of the pc is fine. a cpu overheat turns the system off though.

it could be software... would you be opposed to trying a windows reinstall if it ends up not being anything...
a hard shutdown or soft shutdown?

eg... the pc power just goes off like you flipped the switch or windows itself shuts down by itself and restarts?

for a hard shutdown perhaps psu (how many watts is your psu)

for a soft shutdown perhaps windows update or another program is enabled to automatically install and shutdown your pc?

what type of case, how many fans, what are your gpu and cpu temps? (using the built in temp probes is fine, no need to go out of the way on this). just because you put thermal paste on doesnt mean there isnt a problem. if you have a poor airflow case there could still be a problem no matter if you did or did not change the thermal paste (which lasts a really long time anyways so there isnt much need to do this).

also be sure to note if the restarting happens after extended gaming sessions or not and whether it happens just browsing around and not in games. if its after awhile of gaming... it could be thermal.

in any case a little more information is required to make any sort of clear call.

I have a haf 935 so its not air flow and even when i had basically my regular fan i use in my room blowing straight into the case, and i cleaned out my whole entire computer out so no dust anymore, and I think its a hard reboot, like the lights go of then its right back to loading up bios and then getting into windows to log in and etc. and if it's my PSU,how can i tell that? also it restarts like maybe 12 minutes into the game, so its not like long sessions or anything, it just restarts and then 2 minutes later im logging in. I think it's something with software by chance, but i only found one virus on my whole computer and avg got rid of it. also watts is 750
