Hey all, I am having some problems with some hardware and thought I might ask here if you have any new suggestions. Basics of the system: ASUS A8N-E Mobo, Socket 939 Opteron 185 Dual Core Proccessor 3 GB RAM, installed as 2x1GB+2x512MB, Dual Channel Configuration EVGA 8800 Video Card 4x Hard Drives 2x SATA, 2xPATA. 300GB A piece. 2x DVD+RW. When it began I also had a Hauppage Tuner card and a SB AWE64 installed, but have sense removed them. The system has a duty cycle of 24/7, its a desktop machine/home fileserver. It has been running in its current configuration for over a year. One day out of nowhere, I get a BSOD, which I believe was a memory error. When I attempted to reboot, it began giving a BSOD On boot, "PFN_LIST_CORRUPT". I now have had the same error for weeks. Happens with any boot mode, Normal, Safe, or Safe Command Prompt. I booted into a Live Fedora 10 disk, and it appears to operate perfectly normally, and backed up the system drive as I was going to reinstall Windows at this point. Upon trying to reinstall Windows, as soon as the initial file setup is finnished and it goes into 'Starting Windows' (Not the GUI) it will BSOD with the majority error PFN_LIST_CORRUPT, however I do occasionally get others such as the infamouse IRQL_NOT_LESS_OR_EQUAL, or various other errors. As a result of me deleting the partition on the system drive, and having this error apparently on the install CD before the install even got underway I ruled out files/drivers/etc as the culprit. I've also run Memtest86+ for a couple of runs, in excess of 8 hours on the RAM looking for errors, none found. Swapped RAM with a single stick from another machine, continues to BSOD. Apollogies for being a bit out of order, I was able to get the machine to reboot initially before wiping it by switching from Dual Channel to Single Channel configuration, however the system was still incredibly unstable (blue screen no less than a couple days uptime, on a machine that has seen 50+ days without reboots). Windows Installs are BSODing now single or dual channel. I have replaced RAM with RAM from another machine, still BSODs, I have replaced Video Cards with another one, still BSODs, I disconnected all my drives except 1 CD and 1 Hard Drive, BSODs. I even went as far as to return to my first processor, an Athlon XP 64, and that didn't solve the problem. I can't find another version of this board, and I'll be honest I'm really not finding any new hardware that I am 'enthralled' with. I have 4 PATA drives, and 2 SATA. Finding Mobos with 2 IDE Controllers is becoming very difficult. I was about to order a Core2 Duo (E8500), a new Mobo, and new RAM, but am uncertain if I want to try it with a ATX 4 Pin power plug. I am guessing that the Core2Duo is fine with a 4 pin power, despite the board has an 8 Pin socket, as its a Duo and not a C2 Quad. Am I possibly overlooking anything or is this motherboard shot that I have now?
