I've had my gaming PC for about 6 months now. It's a custom built desktop that's running a Gigabyte AMD Radeon HD 7790 2gb graphics card and an Intel core i7 3770. My PC worked fine up until about three weeks ago. Whenever I try to play a graphically intensive game, the graphics card seems to stop working and my monitor loses signal. All of my drivers and BIOS are up to date, and I have cleaned the registry. I can play less intensive games like Minecraft and LoL on the lowest settings, but if I even try to load Battlefield 4 on low settings, my monitor will lose signal. I sent the graphics card in for repair, and they said that there was no problem with it. I was wondering what the cause of this problem could be. I haven't played BF4 in weeks :(  !

It's kinda crappy actually. It came with the case (Apevia x-qpack). It's a 450 watt psu and has 430 watts on the +3.3, +5, and +12 volt rails. I was thinking that it might be the problem, but it worked fine up until recently.

Yeah I'd put money on it being power supply. Sometimes they can work for a bit before they deteriorate due to the strain.

buy a quality PSU from a quality manufacturer, around 550W is alright

Yeah I thought that it was probably the issue but i wanted to be completely sure before I replace it. Im probably gonna get a Corsair cx600 just for the overhead in case I wanted to upgrade.
