dude i have the same problem :( i bought a new graphic card.. ASUS GeForce 560Ti PhysX CUDA, but it still dont show anything..

@uPheXMovie not always the video cards are the problem you should go back and start cheking it out from where you took it a part and see whats dirty, not plugged in the right way or somthing suspicious that you think it shouldnt be like that. in my case i did and i found out that the motherboard had thermal paste all over.

@94gwilliams yeah but i mean you mother board needs powerful for the graph card

sry for english aim from DUTCH

@TheRatedxTeam This makes no sense. If what you're saying is that you can't use an AMD Radeon Graphics card in a system with an Intel CPU, you're wrong. My system runs an Intel Core 2 Duo E7400 and has an AMD Radeon HD 4850 graphics card and works with no issues at all.

people if u replace a graph card it needs to be the same as the motherboard like AMD on a intel motherboard !

Its the video card

@CGAkurei Correction it was actually my video card... the solution is take out your graphics card boot the comp up normally shut it down then put the graphics card back in and boot it up. it should install the drivers needed and the computer should run fine.

There is something wrong with the hardware a wire is loose there is no post op beep and the fans continue to blow until the computer is turned off i had this problem before its a really simple fix it just means that something was not plugged in correctly check it over even if you are sure. I thought i was sure and it turned out to be my hard drive was loose a little bit. I thought it was the hard drive itself and i almost scrapped it.
