KN8-Sli Video Won't work..Checked Power & Graphics card
I went to start up my computer and it took a minute for video to come up. Third time, I got no video...I had my power supply checked, and the graphics card is OK too...I pulled all the Ram except Pos #1, then re-installed each to check if one of the sticks went bad...I could not get it to recognize anything more than one stick...I had not done any upgrades, nor installed any new software in more than 6 months...Anyone else have this problem??? Any suggestions would be greatly appreciated.

The best option at this point would be to take the x1650 out, put the 8800GT into the bottom slot and test to see if it boots. If it doesn't boot, try the other slot. Some motherboards also seem to have problems with some video cards as well.
Had a similar problem with P5ne-sli motherboard, Intel Q6600 cpu, Nvidia GTS 8800 video card. One day the ethernet just stopped working, but it was working... It would connect to my network but would see "limited or no connectivity" in the taskbar. Went into BIOS and looked at the signals and for some reason only 4 of the 8 signals were getting a reading. Figured a power spike had fried my onboasrd ethenet card. Switched to an old PCI ethernet card... after two years I was doing a fresh install, of XP and for shits and giggles I just plugged the ethernet cord into the onboard with the PCI ethernet card removed. When windows went to validate it detected and installed my onboard ethernet...validated then proceeded to update windows. Over a year later it still works. Never bothered to update BIOS until last month and that was only to fix the long boot time with ATI 5770 video card. Willing to bet that resetting your BIOS will fix the problem for you. Just unplug computer, remove battery, attempt power up to clear any juice still in the system. Replace battery and boot up computer... Also removed a DIMM that went bad around the same time. May have been a factor so try testing your RAM.
As per ur question, this problem occures due to following reason:
1. When ur data cable of ur monitor is bad : Try another data cable this causes only to blink LED of ur monitor which not allows any graphics to display.
2. Your RAM can also be responsible for this problem: If your RAM goes Bad then it doesnot allow any graphics file to load and thus causing not to display anything on ur monitor screen as well as ur system keep restart at POST (Power On Self Test) Operation (When VRAM driver is not loaded.
and the last reason is:
3. Your system is not able to recognise your Graphics card due to Either IRQ inteferance or ur graphics card hardware problem (caused due to bad of VRAM installed on ur graphics card): Remove ur graphics card from expansion slot (PCI-E/AGP)and then plug monitor data cable to normal serial port available in the motherboard (Resides back side of ur system).
normaly ther are two reasons for pc not showing the disply
1 memory card mismach
2 graphics card mismach
get the specification of the mother board and correct the above errors the pc will work if u need more assistace please write to me
OK lets see here!
Make sure your CMOS jumper is set properly on the board(Set to Normal)
Did you configure your bios after flashing the bios(going into bios and Load Optimized Defaults!)?
I don't think it would be another device in the system, but you can try troubleshooting by starting up with only what you need to run the machine (Mobo, memory harddrive, keyboard and mouse) then one by one adding devices back!
Did you have problems like this b4 you flashed the bios!
Try flashing the bios back to an older version!
post back if anything new or if i'm way off!
