gen_prot running memtest86+

  1. I'd be really grateful if anyone out there could offer some help.

    About a month ago I started getting BSOD's on my home PC. It'd been a while since the machine was rebuilt and I was still running dual boot with Win 98 and XP home. I thought a rebuild might fix it so brought a DVD burner, took the apporpriate backups and took the plunge. I re-formatted the primary drive with 2 partitions (25Gb C: for the OS and apps and 55Gb D: for data).

    Re-build eventually completed, but I continued to get BSODs - these had various messages IRQL_NOT_LESS_OR_EQUAL, PAGE_FAULT_IN_NON_PAGED_AREA AND others. I installed and ran windbg but there seemed little consistency in the output. Having looked around a few forums I guessed it might be a RAM issue.

    I ran memtest86+ v1.70 and got repeated errors on test 7. I had 1 stick of 512MB DDR pc2100. So I took the stick out of the slot (we'll call it slot 1 as I don't know if they're labelled and haven't looked). There was a bit of dust so I blew this off and re-seated the stick in slot 1. This time I just ran test 7 and this was the only test where I found failures before.
    At the end of the 3rd pass it just hung. This happened twice so I took the RAM out and put in slot 2. After 4 clean passes of test 7 on memtest86+, it was looking good. ;0)

    The machine hung on first reboot, but was ok after that for 10 mins or so, and as it was getting late I shut down and left it. Next day - more BSOD's!!.

    So I brought a new RAM stick (512 DDR PC3200 - compatible - local dealer told me it would work with my board). Took out the old RAM and put the new one in slot 1. Booted up PC - fine for about 30 mins then I shut down. Next day - PC starts freezing and this is interspersed with more BSODs - now all PAGE_FAULT_IN_NON_PAGED_AREA. Ran memtest again and got loads of errors on pass 2 of test 7. Switched RAM to slot 2 and ran memtest again. Failed with unexpected interrupt gen_prot and a handful of hex error numbers.

    I also am still getting random BSOD's - last 2 were PAGE_FAULT_IN_NONPAGED_AREA with the following info:

    bf9aff98 a0fa99bf89 mov al,byte ptr ds:[89BF99FAh]

    I'm stuck now - is this a mobo error - could it be a heat problem? Please help cos I don't want to shell for a new mobo if it's not the problem.

    mobo is ASUS A7N266M

    I can attach minidump files if it will help

    Any help greatly appreciated

    Thanks in advance.

    problem resolved

    brought a replacement base bundle off a friend who had upgraded. Switched the hard drive and the new RAM in and re-installed XP - all fine now.
    Unbeleivably XP activation worked automatically even though nearly all the hardware (except the HDD and DVD RW Drive) had changed. I did have to activate office over the phone though - inconsistent MS!
    Just so I know in future, can anyone tell me why I didn't get any responses - perhaps I've used the wrong board?
