Specs: Windows 7, 4.126 GHz / 4000 MB
When I go from a window to my desktop the entire screen goes black. Not the black where there is still the back light on but black as in completely off. When I press ctrl+alt+delete or when I switch to another window with alt+tab it will come back up. I have tried rolling back my video drivers and re-installing them, but this didn't help. Any ideas? Thanks

You show: "Windows 7, 4.126 GHz / 4000 MB" on top. This tells me that you are overclocking. ((If you give us more details on your system, it will not feel like we are pulling teeth)) If you are overclocking and using onboard graphics, get a distinct graphics card, your oc is affecting your graphics ability. If you are overclocking and you use a PCIe16 graphics card, make sure you set the PCIe freq. to 100. If you are overclocking your graphics card also, you might consider rolling back on that a little too. Finally, have you stress tested your OC thoroughly? Include more detailed information for a more detailed assessment.

Alright well I doubt its from the OC but I have an AMD 555 BE that I unlocked and overclocked. 4000 MB of ddr3 RAM, and I am using a ATI HD 5450 PCIe16 graphics card. The PCIe freq. is set to 100 MHz which I have not ever changed. I have overclocked the GPU; howerver, rolling back on both the CPU and GPU OC haven't solved the problem. Is there anything else that I might try? I appreciate the help.

From what you just added, we probably could eliminate OC'ing as a probable cause. This will be a process of elimination.
If this is a recent problem, you can try doing a system restore to a date before the trouble began (cannot hurt, might help).
This does not sound like a memory problem, but it could not hurt to test your RAM, either with windows memory tester or Memtest to eliminate the possibility.
It could be the graphics card or the graphics card's memory. If you have another graphics card that would be suitable, you can try swapping that out as a test, or if your board has built in graphics, you can try that as the test (just watch the OC with onboard graphics, they don't always do well together).
