gtx 780 no signal

#1Darkblade9116Posted 8/1/2014 7:21:15 AM
My brand new gaming pc arrived today, i was so happy. But then i updated nvidia and after a restart, i get no signal on my monitor..

I use an hdmi connection. It does display the bios info and windows logo, then briefly the desktop shows and then i lose the signal..

Any ideas?

Open up the computer and check the power cables. If the PC was shipped to you then something may have come loose during shipping.

It is plugged into the graphics card, and not the integrated graphics?

It is. Just now, i was able to keep it stable after startup. So i ran 3dmark to see if the card would work. For about 10 seconds it did. After that i got a gray screen. Which it is stuck on at the moment..

Also, on startup, a few red lights show on the mobo. 1 at the pci slot my card is in. But what is wrong? It is connected so i have no idea

New info: if i select "optimized defaults" in the bios, startup is normal. I can start programs en get into settings. But as soon as i run some graphics (games or benchmarks), things go south

I can watch youtube videos without problems (so the card does allow that at least)

What motherboard is it?

Have you tried plugging the card into another PCI-E slot as well?

Try resinstalling the nvidia drivers. It looks like something must have messed up when you upgraded the drivers.
