Hi all! Please accept my preemptive apologies for the book written below, but I figure that the more you know, the better I'll be. I'm a virgin participant here, so be easy on me. I was sent to Windows 7 Forums after a friend of mine and finally admitted that we're clueless with respect to an issue that struck out of the blue.
First, I was getting a BSOD at random but never with the identical error sequentially. I can no longer get to the dump file to review it, but I did list all of my computer components as I know that it can be frustrating to help people when they leave out the details. As I said, I began having a IRQL_NOT_LESS_OR_EQUAL error a few days ago, so I backed up all of my data and started troubleshooting. At this point I've reverted everything back to the essentials until I can get this sorted.
Now, my custom PC began rebooting overnight so I missed the early warning signs as it would always be booted to the OS, but I recognized that all of my software appeared to have crashed. Then the system began to act unpredictably and began crashing and rebooting right in front of me. About every third or fourth boot, the 9660GSO would start with the on board GPU cooling fan sounded as if it was in a perpetual loop. It would not post and generally just kept resetting the video card's fan on high for a moment and then it settled to a normal speed, then restart over and over.
Here's what I am certain of:
A.) Verto 9660GSO works perfectly in a different PCI-e system
B.) Any other PCI-e card works flawlessly in the problem machine
C.) Every monitor that I've used works on the problem system as well as the test machine
D.) I can get the motherboard's onboard VGA port to boot into Windows as expected
E.) I have a system with an upgraded power supply that is well beyond the required spec of the entire system
F.) Tried reseating the card, cleaning contact points and resetting the BIOS to the default settings, but no change.
Now, I cannot get the computer to post at all with two correct system RAM sticks, and I believe one of them has either failed or is just hates me. If I boot with the known good RAM, I can get the VGA output to work...but the 9660GSO will not start with the known good RAM.
Is it possible that my GPU requires that BOTH RAM sticks be present to boot via my 9660GSO ports? Is it conceivable, or even possible that the RAM is dependent upon the video card to work properly?
I'm in way over my head here...so I'll try anything to get this machine back to work.
Thanks so very much!
