I have a GTX 1050 SC from EVGA [2016] I overclocked a little bit [100mhz more] and then saved it my computer crashed after and I left it for a day then booted it again it was fine till I opened games [PUBG, [Old] Fortnite, etc] and they all crashed I went to Micro Center is to buy a new power supply though I had a 350W Thermaltake PSU and do a clean install of the drivers with DDU. In which I did and it kept crashing. [Errors like not enough VRAM, not enough memory, etc.]The GT 730 worked why not this?! [Used Precision X]
