Turned it on and nothing came on the screen, I fiddled with the monitor a bit and changed the connection to the second output and nothing changed. I tried the same graphics card in a different pci-e lane - same result. I then tried my second graphics card in both lanes and again, it was the same. My graphics card is an 8600 gts, my second graphics card is a 7100 gs. Last time i tried (24th december) the 7100 worked perfectly in it but it didn't work with the 8600. I know the 8600 works though because I am using it right now in my crappy socket 939 motherboard.
I thought it might be the power supply so I unplugged everything from the back, removed all the fans, dvd drive and took a gig of ram out but it had no effect. I'm really stuck and wondering whether I should just sell the parts off individually but I don;t really want to if one of them is faulty.
One last thing I tried was to reset the cmos because I might have changed some settings when I was in it last time - not sure why that would make the graphics not work but I looked in the manual and it was completely wrong. The manual showed a picture of 2 jumpers on a row of 3 pins, but on the motherboard there were 2 jumpers which had holes for 2 pins, then a row of 4 pins with a space, and under it a row of 3 pins. It said to move the jumpers from pins 1 and 2, to 2 and 3.
J = where the jumper is
+ = a pin
- = empty space
In the Manual:
from J J + to + J J
On the actual motherboard:
J J - +
- + J J
The only reason I mention this is that if the problem is in any way related to the bios then I have no idea what to do to reset it.
Please help if you have any ideas at all, thanks,
