So yesterday I joined in gta V.I have a amd x4 620 processor with a gtx 460 OC.Once I joined my screen blacked out.After I rebooted my pc nothing was showing up.After I changed the PSU,I got it running but with screen artifacts and a yellow triangle on the gpu in device manager.It wouldn't recognize the gpu and after I installed the drivers again,It jsut blacked out.Now when I turn it on,the fans work and everything the system boots but with no signal to my monitor.I tested a 9600 and it did work and the iGPU aswell.Can i do smth to fix it?
