Windows 7 Black Screen on start up

My computer had started acting a little funny before this issue had arived. It showed a significant slowdown on startup and applications took a while to start and sometimes would not work at all, but i did not address the issue because i did not install anything recently other than software to enable a ps3 controller on my computer from motioninjoy. I have heard/ seen many negative things about this program and regret ever installing it on my computer. Also the emulator I was using was pcsx2.


I am not able to start in safe mode because the screen goes black before i get the chance. I only get the initial boot up screen where i can press f2 or f12 and then it goes black


i have been using my computer on this particular setup for 3 months now and nothing has ever caused a problem, please help me i need this computer for school work!


my specs are
dell studio xps 8100
radeon hd 5700
8gb ram
intel i7
hooked up to a hp w2072a monitor using a dvi connection


some additional information:
when left on for an extended period of time my graphics card starts to work hard but nothing comes up and the screen evenually turns a pale blue (not the normal bluescreen) and no text comes up

I think it is a driver issue but I am not sure any feed back would be appreciated!

sadly I cannot even log in, the screen goes black after the dell boot up screen

You might have a bad power supply, or your CPU power connector might be loose. Try opening the case and check that all of your power connections are secure.

I would think not? I have not moved the tower since I had set it up there. Wouldn't those problems need to be caused by something? I will however give it a look just in case thank you for your suggestion

I just checked the connections and they all seem good, I even unplugged and re-plugged the power to the cpu. I'm going to be going home soon so I will be able to pick up my windows 7 os discs and attempt to restore my computer then. I will keep you guys updated and thank you for helping me I'm in a tight spot right now.

To follow up on my previous post I have my recovery discs but I am having trouble restoring the system/ finding the problem. At this point I just want my computer back at any cost meaning I do not mind a full system reboot or format of the hard drive. If anyone could point me in the right direction that would be great. I can boot the PC strait from the cd drive so loading the discs is no problem, I just underestimated how complicated doing this with no prior knowledge is.
