UPDATE (6/27): The new Corsair CX600 PSU came in the mail and I installed it. I went to load a video from youtube and it did the same thing: screen went white and the pc restarted. This is my only PC so it's starting to get a bit frustrating. I'm assuming it can either be the graphics card or the motherboard that needs replacement. Gonna send the PSU back tomorrow (it's quite loud sometimes) and order a cheap graphics card. I really need to get my PC back on it's feet

Hi. I've been looking on all the forums and can't seem to figure out exactly which component of my PC needs replacement. I'm getting a black screen when I start any youtube vid or load up any game. It first started when I downloaded a game called Rift.
First symptoms were: minor screen tearing and blinking screen, which went away when I exited the game. Then, the symptoms got more severe as time went on, and I'm now at the point where I get a black screen 5 seconds into a video or game.
When the black screen happens, there are two different outcomes depending on the situation.
First: it will just go black and I will still be able to hear the game sound for a little bit. This outcome usually happens after a game is loaded
Second: the screen will turn black with gray stripes and the sound seems to skip. This outcome usually happens after a youtube video is loaded.

Attached is a screenshot of my current HWMonitor readings

Processor: AMD Phenom X6 II 1055T 2.79ghz
Memory: 6GB
Hard Drive: 1TB
Video Card: AMD Radeon HD 5670
OS: Windows 7 Home Premium x64
Manufactorer: Dell
Model Studio XPS 7100

I'm out of warranty and I'm making an educated guess that my motherboard needs replacement and that it's capacitors are faulty.

Thing's I've done/tried: Thought it was the graphics card. I used a bottle of compressed air (short-bursts) to clean the fans and inside the case. I unscrewed the fan housing on my graphics card and cleaned the dust that was around the heatsink under the fan. No luck so far.

Important to note: my computer was hooked up to an outlet that wasn't grounded for a long while (almost 2 years). I am now connected into a properly grounded outlet. Could the bad outlet have fried my components? My temp readings have gone down significantly after switching power outlets. The graphics card used to read 70C but now is at a comfortable 52-55C. The only temp that is high is the TWPIN2 temp (whatever that is). Is that the motherboard?

I have run every diagnostic test available. I have turned off AMD's Cool and Quiet. Nothing so far has told me exactly what's wrong.

Thank you so much for all your help!

Yes it is probably the PSU. Sounds like that is the problem, whenever you pull too much power the system shuts down. Try a different PSU and see if the issue persists. If it does I think it is a mobo issue.

So I replaced my current PSU with a Corsair CX600 and I still have the same shutdown problem. It only happens if I watch a video online or start up a game. Anything that is slightly graphic intensive will make the computer go to a white screen and restart. I now have to pay a 15% restocking fee to Amazon. Gonna try to replace the GPU and hopefully that does the trick. Otherwise it's the motherboard.

Does the Phenom II have integrated gfx? if so try testing with that, just to see if its a gpu issue. Right now I think the only possible problems are a blown mobo cap or a bad GPU.

So yea I tested the computer without the graphics card in the tower and it played videos just fine, no white screen. That made me determine I didn't have to buy any PSU at all...i couldve just bought the card and been done with it.

So I bought a new card, a R7 260x b/c I noticed it got high ratings as an entry-level card. I can play games now with no white screen, but the R7 seems to have lower frame rates than the card I'm replacing. It's quite disappointing. I'm replacing a Radeon HD 5670 to a Radeon R7 260x. I read online that the R7 gets around 70fps in the latest games but Im getting frame spikes.

I uninstalled the old drivers when I installed the new card. I then updated the drivers to the latest AMD driver direct from the website.

What happens when a graphics card doesn't recieve enough power from the PSU? Does performance take a hit? I'm assuming now that I have a new card, I should've maybe kept the 600Watt PSU to make sure it can sustain the power. Though the R7 was advertised as a low-power machine, it requires external power from the PSU unlike my previous card. I think that might be the cause of the low frames. Any opinion?

What is the spec of your PSU? Also what games are you trying to play? The 260x is a good entry level card and should play mostly everything on low to medium, but the phenom is an old processor and might limit you in some games.

You shouldn't be having a problem with that PSU, 460W is enough for a 260X and Phenom. I don't know why you are getting lower framerates though. The 260X is a much faster card than the 5670, and after reading more on your processor it should not be bottlenecking your graphics card.
