Extremely slow boot up with new computer

[uber345]

I helped build a new computer for a friend the other day.

Intel dual core 3.0 GHz processor
2- 2GB RAM
Windows Vista Premium
750 GB SATA HD
GeForce 8800 Graphics card

It was working perfectly when we finished, and we loaded up and installed all needed things for vista and Internet... no other programs were installed. Then today we bought another GeForce 8800 and bridged the two together. It needed 600 Watts and computer only had a 500 Watt power supply... we did turn it on but nothing happened.

Replaced power supply with 1000 Watt and turned it on... The computer displays the initial motherboard XFS symbol and takes ten minutes to get to phoenix BIOS screen. There are no error messages but you can see CMOS refreshing as page loads... So we let it continue with boot up and it still has not booted up. Any suggestions.

The BIOS worked fine except for the excruciatingly slow speed.

We took out other graphics card and have tried using a different one also. And have tried a different processor, RAM and have taken out and put back in everything. Nothing has changed the speed.

Check the motherboard manual, if using dual graphics then there will be a selector card between the graphics and this needs to be set to Dual graphics for them to work On my Asus board it's the Asus EZ selector card ). You don't say what motherboard you have so cannot be more specific.

Well the motherbord is a NVidia 680i SLI. However I only have one graphics card in at this time and I bridged them together correctly the first time. The problem started after I tried them bridged with only a 500 Watt power supply, but now I have a 1000 Watt. It works... just extremely slowly... and I would like to know why

Because if the motherboard shorted out or something else did, it wouldn't even turn on... I assume.

What board do you have, on my board the graphics do not have power plugs on them, but the board has an ATX plug near the graphics cards to supply more power.
