I haven't played graphic demanding video games in the past half a year. Yesterday I decided to play csgo again but my game would crash right after I joined a server. I lowered to setting to low/medium and disabled anti aliasing and then i was able to play with frame drops every now and then but I think that's because no anti aliasing. Today I decided to test it and whenever i launched ARK my game crashes right away. I tried launching msi kombuster with gpu not being overclocked and fan speed and 92% and it crashed half a second after I started it. Yesterday after a few tries of trying to get csgo to work I got the screen that you get when you first boot a PC it said american something I don't remember i know it says the same when you boot PC for the first time and it mentioned something about a PSU error. I looked up some solutions on net and concluded it's probably the PSU's fault. Now, I can't afford both new GPU and psu so I came here to ask if there's any way to be 100% sure if it's PSU or GPUs fault.
