Just put a comptuer together

p6t deluxe motherboard, 4 gigs of ram, 500 gb hard drive, intel i7 2.66 and a geforce 9800 GT.
Hooked it up. Everything boots, no beeps for missing ram, but the video isn't working, tried both DVI slots, and all three PCIE slots. But to no avail.
I'm at my work, and right now we're using a VGA to VGA-DVI to DVI converter.
We havn't tried DVI to DVI yet. What could the problem be.

PCI power from PSU to 9800GT. (6-pin connector @ rear upper edge of 9800GT)

Recheck all other connections esp. 8 pin located close to CPU.

okay, just did all of that, Still having problems.... I've tried two 9800 GT's and two XFX graphics cards.. All are doing the same thing. The monitor will turn on for like 2 seconds to say: Input not detected. Then it will shut off

Is that before or after the post screen?

can you perhaps boot into safe mode?

It could be driver related or maybe just a faulty cable.

yea, its me endolitematrix....
I'm at home now. I have no OS on it. Its not booting, I'm on a completely different monitor and using different cables.
it's doing the same thing it was doing at work.
when I plug the omintor in. The LED light on my monitor turns blue, as if its on. Then it says "going to power saver mode"
It's like it reads its there. but not REALLY there.

Try reset CMOS.
Use jumper on MB or remove 3v battery for a couple of minutes.
Make sure you are on a non-carpeted floor and touch the case with bare hand before reaching in. ( static electricty caution)

Look in your manual for jumper location.

You didnt say if you have stand-off's between the MB and Case (Spacers). The underneath side of the MB is not to touch the case.

did that... I hooked up a keyboard and mouse even this time...
Even though i have no picture.
I'm hitting the num lock and caps lock key.. its responding, the lights turn on and off accordingly, and opitcal mouse via USB is lighting up... Still nothing on screen though.
It's weird.
When my monitor is NOT connected
it says with a blue light "Check system cable"
then when its hooked up, computer on, it goes into power saver mode.

Unplug:
HDD (s)
DVD/CD
any/all USB Devices
Any fire-wire, E-Sata
Keyboard & Mouse
all front panel connections except PWR

Basicly you want MB, CPU, PSU, GPU,1 stick RAM, Monitor, nothing else.

Retry

nothing.
The monitor... even when the board has no power.. will go into Power Saver... (all monitors did this with different cables) after I plug it in.

yea.... I have two 9800's because I was going to SLI them... both of them are doing the same thing
