Computer: XPS720 h2c
Motherboard: XPS720 (thats what it says in the dxdiag - heard its a BTX board don't think its that old though has three PCI-E 2.0 slots (it ran the 8800GT's in SLI, one broke a while back so I disabled it).
I just received the Nvidia 450GTS to upgrade from the 8800 GT.
What Happened
Few days ago 8800 GT card started acting weird about 10 mins after computer starts up my screen look funny like a column shifted over with sideway slashes.
Got new graphics card, but now the new video isn't sending any signals to the monitors, and the old one which I haven't use since (its been about 3 days) also cannot send out any signals
I tried:
1) Testing with different monitor (same result in both VGA and DVI for both video cards).
2) Tested Monitors with another computer (worked fine)
3) Tried this method hold down power button w/o power cord attached for 30-60 seconds (tried both)
4)Tried different slots (only two slots can fit the card PCI-E 2.0)
5)Tried changing the thing that connects to the Power Supply
I thought it was the motherboard so when the power supply (from the cord) came out the mobo beeped really fast got scared pulled the plug on the comp.
When I hit the power button the lights and everything come on power, cooler, HDD (I hear it spinning), video card fans starts spinning.
Edit: PSU is 950w
Additional Note(s):
1) I don't think I have a intergrated video card (theres no slot that I recognize anywhere on it)
