I recently bought a new case to replace my old one. Yesterday I moved all the components from my old case to my new one. For some reason when I boot up the computer the monitor stays black and doesn't detect that the PC is on and connected. Everything is working and running and all the parts are exactly the same as it was in the other case apart from a new CPU cooler and case fan.

I don't know if this is all needed but I included it all

Biostar TA970XE
AMD Phenom II X4 965 Black Edition
Western Digital 500GB Blue
Seagate Barracuda 1TB
MSI Radeon HD 7770 1GB
Thermaltake TR2 600W
Corsair XMS3 (2 X 4GB)1333
Coolermaster Hyper 101

Any help would be appreciated.

If it still doesn't work break it down to the basics to find the disconnect. Both with only cpu and memory with onboard. Add components after every boot until it stops booting, if you have everything booted just fine with everything connected at the very end, it probably was seating of power or connection.

More than likely house is right with either motherboard connections (24-pin or if your mobo has extra 4-6 pin power conector) not being plugged in, or video card not being plugged in. But I would try to reseat the video card while you are at it.
