Graphics card reboots

Hello everybody,

I'm assembling a new computer and ran into a problem. The graphics card seems to keep rebooting. It sounds like it keeps trying to start up.

- Gigabyte GA-MA770T-UD3
- AMD Phenom II X4 955 3,2GHz Black Edition
- Antec TruePower TP-550- Powersupply
- Kingston ValueRAM 2 x 2 GB DDR3 1333MHz
- Asus ATI Radeon 5850 PCI Express 2.1 x16 1GB DDR5

Everything seems to be connected and powered. When I try to start it up it gives no beeps or sounds that are out of place. When I run it without the graphics card it seems to be okay, but there's no onboard graphics card so I have no way of checking.

Also: I have not yet put thermal interface material on the CPU as I only wanted to test if it all worked. Is this important to do, because I haven't done this for my other pc I've assembled. (an i7)

Any ideas? Any help would be greatly appreciated!

Thanks, Tijn.
 
I still don't really get how a video card can be "trying to start up". What are the symptoms? Is the fan switching on and off like it couldn't start up or something? Do you get any video output?
 
I know this problem ..........I tried to install an old gameport and the system kept rebooting.........so whenever i disengaged it from PCI slot..............voila the system worked well..................i even took it to market of bulk sellers.............40% of them said .........it is the card............which is causing the problem.............

MORAL OF THE STORY: Buy another card my dear friend...............you have a card which would not run.................
 
is the gpu bios posting? it's the first piece of hardware that posts followed by system bios. how can you run your system without a graphics card if it has no onboard gpu?
a gpu is an essential component needed for system bios to post.
