Hey guys, was wondering if ne of you could help me solve a little problem.
U see, my pc is starting normally, but just turns off after 5-10 seconds.
I just got my new Graphic card, it works ofc :p  XFX Geforce 285 GTX (BLACK EDITION)
i know that the MB works, and that the RAM works, and i know that the CPU and the graphic card works.
The hard drives works except one, so could ne of u guys help me? :)

We have a sticky for troubleshooting system problems. The first thing to do is perform EVERY step in the READ before posting about boot/no video problems! sticky at the top of the forum.

Is this an existing system, or a new system? Has it worked before? What are the complete system specs?

What kind of PSU do you have? It could be insufficient or dead :o

Maybe your PSU cant handle such a powerfull GPU. Try tunrning your computer on WITHOUT the GPU.

If your computer stopped working when you installed a new video card, switch back to the old one and see if it boots.

Did you uninstall GFX drivers before taking out the old card ?

That makes no difference, as drivers aren't loaded until windows boots.

Check and see what power supply you have.
