Just bought an i7 860 and got it installed. Went to turn on the computer, and I seem to get signal to the monitor, but no actual picture. Just pure black (no backlight). I reset the CMOS, and still get the same issue.
Well, to start off. When you first boot up your system do you hear it post(1 single beep) because if not then you might have an issue with the new processor.
What makes you think the monitor is getting signal? If no back-light is on that typically means that the monitor is off or is in sleep mode due to a lack if signal input. At this point I would recommend that you re-seat both your ram and your video card. Although if your system isn't posting then its probably more to do with the CPU.
Processors are very resilient. I tend to find that they very rarely go bad. Like maybe one in a thousand. I've seen systems that have taken surges from lightning storms and had every component dead, except the CPU. hopefully that puts your mind a little at ease.
While you RMA that card I don't suppose your board has on-board video to see if your system gets up and going? Either way, got my fingers crossed for ya.
Just as a point of interest the i7 Kits seem to require the RAM Dimms to be in the white slots if you have two of them. So if you have the RAM in the other slots with the white slots empty then it wont Post.
