New Card, Computer Restart Loop

I recently bought a new video card the Radeon 3870.

The card worked fine for one day, no issues whatsoever restarted and booted the computer up fine.

Now today I came back to the computer turned it on and it seems to reboot constantly, like power cycling (about 7 times) and then finally stops restarting and its apparently loading just not displaying anything on the screen. After taking out the card and plugging in another monitor onto the on board video, it booted perfectly fine. But when the cards in it still does it.

I plugged in the card and plugged one monitor onto the on board and one onto the card. It did the 7 restart loop again, and when it stopped and loaded properly it displayed through the on board video monitor.

My power supply is a crap Gigatech 450W PSU and i'm suspecting it to be that. ATI recommends a 450W PSU although like I said it was working fine before.

My motherboards a GA-M61SME-S2

Any help would be great, the new cards been nothing but trouble.:mad:

EDIT:Upgraded to 550W still the same problem

Sorry it's 450W and yeah i'm pretty sure it's the PSU although like I said it was working fine, and now I pulled out unnecessary drives to test only on the basic stuff to reduce wattage, but still fails to load properly.
 
OK Updated power supply to 550W, the PSU works fine, yet it still doesn't work, same issue as I have stated.
 
I know it usually does it automatically but...did the onboard graphics disable properly? maybe it has the same IRQ value as the new card and is causing a conflict!!

Can you boot up in VGA mode?
 
I would have suspected it to the be the video card at first. Can you disable the onboard video in bios? (i'm not sure if you can or not)

Have you tested another video card on your motherboard? Other than that, i would have to say you'll have to RMA the 3870 :(
