Black screen on MSI P43-C51, memory incompatible?

Question

Hi!
I've recently bought a new computer. Everything seems to be in good order, except when I start it I get a black screen. Disks are spinning, I hear it boot up and everything, lights seems to be in the proper places, but the screen remains black.
Searching around, users with similar problems usually seems to have memory problems, therefore I'm suspecting that's my case too. I've triple-checked that they are properly inserted.
Specs:
PSU: 400W Corsair
GFX: Sapphire Radeon HD 5830 1GB DDR5
Motherboard: MSI P43-C51
Memory: 2x2GB Kingston 1066 MHz DDR3 CL7
CPU: Intel Core 2 Duo 2.93 MHz
Is the memory incompatible as I suspect, or is there any other answer? Would be thankful if you could tell me. Thank you.

Your problem could be caused by any (or several) of the following things:
- memory problem (test each stick individually in the first memory slot, test other memory modules)
- PSU problem (PSU defective or power connectors not hooked up properly (24 Pin ATX, 4 or 8 Pin +12V CPU, 6/8 Pin PCI-Express (video card))
- shorting issue (test the board outside the case on a non-conducting surface in barebone configuration)
- defective CPU
- defective video card
- defective motherboard (bent or broken CPU socket pins, defective sub-circuits, defective chipset components, defective voltage regulators etc.)
- CMOS mess (--> >>Clear CMOS Guide<< )
