My computer has been acting weird ever since I got it. My computer specs are listed below and in my opinion, with it's hardware it should be running everything at crazy speeds with no problems (games I mean). While it doesn't run games terribly, it isn't as great as I imagined (20-30 FPS in some games, 20-150FPS in WoW, would think that it should never dip below 20 but it does). This, I can deal with although I think something is wrong. The other problem is that my computer completely crashes sometimes. It happens a lot while I am in Adobe After Effects scrubbing or rendering. It happens other times randomly, but not very often outside of video rendering (even did it while rendering in windows movie maker once!). The screen goes black, the fans slow down and the computer is unable to be powered down unless the switch on the power supply unit is flipped or it is unplugged. I have checked the temperatures of all components of my computer and they seem to be fine. I ran the windows memory test and it came back fine so I don't think it's my RAM either. All my drivers are up to date and the only problem I could think of is something maybe with my power supply. Please help!

System Specs:
- SAPPHIRE Radeon HD 7970 3GB 384-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card OC with Boost
- AMD FX-6200 Zambezi 3.8GHz (4.1GHz Turbo) Socket AM3+ 125W Six-Core Desktop Processor FD6200FRGUBOX
- MSI 760GM-P23 (FX) AM3+ AMD 760G Micro ATX AMD Motherboard
- COOLMAX ZU Series ZU-900B 900W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Modular Active PFC Power Supply

Unfortunately, I do not have another GPU to test. I already have Whocrashed on my computer and no minidump file is created on crash, despite me making sure that the settings are correct in computer settings to make a minidump on crash.
