Im having a huge problem with my graphics cards

First of all i need to install drivers for my 2xevga 8800gtx 768mb graphics cards and then when i do i you have to restart your computer. Upon the restart my monitor says "no signal" and then the light turns amber. I am in desperate need of help and have tried all the drivers there are previous, latest, all of them

Now i cannot even see the post screen so i cannot go into safe mode and uninstall this driver. Please help

Processor: Intel Quad core Q6700 @ 2.6Ghz
Mother Board: A-Bit IN9-32MAX 680i (with full overclocking options)
Memory: 4g Corsair DDR2 XMS2 800MHZ 4-4-4-12 (with Corsair RAM cooling)

1x IBM/Hitachi 160GB 7,500RPM SATA
Optical drive: LiteOn 20x DVD/CD+/-RW/RAM Lightscribe
Power Supply: Galaxy 1000w modular PSU, SLI
WIFI card.

Water cooling details:
Processor; D-TEK Fuzion CPU water block

Graphics card; 2x EK-FC8800 GTX (with black acetal top)

reset the cmos
turn the computer off
remove the power lead from the back
take the side off
remove the cmos battery
move the cmos jumper from pins 1 and 2 to pin 2 and 3 and the back to pins 1 and 2
replace the battery
put the side on
replug in the power lead
boot the computer

there can be 2 solder points you touch with a screwdriver
2 pins you touch with a screwdriver or use a jumper
a cmos clear switch or button
there will be a diagram and instructions in your manual
if this gets you back into boot then try installing the drivers that came on the video setup disks with a/virus disabled for the install

I am not one to usually post to discussion forums, but this is a problem that had me stumped for the better part of a weekend. I had a 7900 that just stopped working one day. I had sound, hard drive, bios splash screen, and windows splash screen, but after the splash screen, the monitor went into power save mode.

So, I replaced the mobo, the 7900 with 2 8800s, the memory, the psu, and reinstalled vista (a half dozen times). The same thing every time - all was great with the native windows drivers, but as soon as I installed the nvidia drivers, blank screen after the windows splash screen.

On a far-flung hunch, I replaced the DVI cable from the graphics card to the monitor. Low and behold, everything starting working correctly. I took a look at the cable, and noticed that one of the connectors was fitting very loosely on the monitor input. My theory is that somehow (vibrations, moving the monitor, moving the cables, etc.) maybe caused one of the connections or conductors in the cable to stop working. Perhaps the native windows drivers do not use all of the lines in the DVI cable, but the nvidia drivers do - this is the only way that I could explain what happened. I hope this helps someone else stop banging their heads on the wall. Good luck!
