Hello guys, I don't understand much about pc's, but few weeks ago i built a pc, my specs are GTX 1650 4gb, 8gb ram, h310m pro, i3 9100f and matrix 800w psu(i posted a picture of it)
I have a problem after i use my pc for some time(7-9 hours),at some point the screen freezes and after few seconds turns black,then turns on and that repeats again after 2-3min...And i have to shut down my pc, and take a 20-30 min break.. I think its my psu but i don't really know... Also once my graphic card *crashed* or whatever and started using 100% of itself and the whole pc was lagging, I had to reinstall my gpu drivers and restart the pc for it to start working again.. i really need help the pc is really new and i need to fix it before it ruins other components(if its my psu), also i dont have any coolers, should i buy coolers instantly??
