No signal, 8800gts. Please help.

Hello,
Hi, I have just put together a new machine, using new parts and a few from my old PC.
Here are the specs, its a bit 'outdated.'

Mobo - Asus P5B VM-SE
CPU - Pentium D 965, 3.4ghz.
GFX - BFG 8800GTS oc 320mb
RAM - 1x2gb Team Elite cl5.
PSU - 550w.

Basically; The motherboard and all components work fine using the integrated , (intel GMA x3000). However using the dedicated card i get 'no signal' on the screen. It does not display the post/boot. The card its self is in working order.
I have the 6pin power cable plugged in, connected to two molex cables(also tried with one). When I don't have the 6pin connected to the card i get a very high pitched continuous beep from the mobo(or card?), this beep continues even when windows is booted to desktop. when the 6pin is plugged in no beep though.

This is as much detail as I can think of, if anyone can help me solve this it would be appreciated greatly. If you need to know anymore please ask.

Paul.

If the card works with no issues in another PC (I don't mean before you moved it, try it again now), try a different power supply that has a dedicated 6 pin video card adapter. It's really bad to boot to a video card without a power adapter, I killed my favorite video card (ATI 9800) several years ago this way, upgraded RAM, and my hand loosened the power adapter, card fried.

This sounds silly but when using a pci-e card you need to plug you monitor into the card not the motherboard.

Once you plug it in and post you may be able to set the bios to use the onboard video as the main video, however most boards will automaticcly use the pci-e card and shut off the onboard with no option to enable the onboard.

I am currently running 3 different cards on Molex to pci-e adapters. Been doing it for years. As long as the PSU has the wattage and the amps on the 12v rail there is no problem with it. The way I look at it is if it was risky would every GPU manufacturer in the world include adapters with new cards?

It would be an issue if the connections he was using had issues, or if it was an old and cheap power supply that can't run the new components.

i have booted in to windows and bios using the integrated graphics, changed settings in bios to [peg/pci], but no signal and yes i have a dvi cable in the card, and a vga able for the mobo graphics. when my friend used this card he was using a dvi - vga adapter. do you think this could have an impact? im going to try using an adapter to see if its just the dvi thats not working correctly.

Do you have two monitors? or two different imputs into one monitor? To simplify the trouble shooting, use only 1 wire from the monitor to the pci-e card. Un plug the extra wire from both the mother board and the monitor.

You can try to reseat the pci-e card, make sure it is set in the board good and tight.

Using a DVI or a vga with a DVI adapater should not have any impact but it is always possible that the DVI wire is defective.

Check the video card again in another computer also. 8800 have a high failure rate.

80% chance it's either the video card or your power supply.

The card was checked on a friends machine, using a dvi - vga adapter, on my machine i am using a dvi - hdmi cable. I will Tinker with it when i get home tonight. It's either a bios setting, (a lot of options in this bios that i am not familiar with, or they are using different names, I assume peg, is pci-e?) I am starting to think its the PSU. Im not sure on the make, but my brother uses the same one and is running a 9800gtx, is the 8800 more power hungry?

Wait... you did not mention dvi-hdmi cable. My bet is its that cable. Many video cards are very touchy when it comes to HDMI. As i said above remove all extra cables and go with a DVI or a vga with an adapter.

If its not the cable my guess would be the video card died. As some one said they do have a high falure rate and the card has to be like 3-5 years old.

Hmm, the card had 2xdvi and 1x s-video, I will see if i can dig out a vga adapter, feel I'm losing a bit of quality through vga though.
If thats not the solution I'll send the card back. Thanks for your help. :)

Rule out the adapter, run it straight to DVI. The only thing in the BIOS that should need to be changed is the primary video, and even that I've never had to change in systems I worked on, it should see the add-on video card and automatically use it as the primary.

Quick update, I solved the problem, seems the psu was to blame. Brought a much better one and everything is now sweet. Thanks again guys!

You're welcome! Make sure you keep that 8800 clean from dust and also the PC vents. Those cards cook their chips more than a Doritos factory.
