Windows 7 BSOD Upon Boot


I am getting a BSOD upon booting Windows 7 x86. It appears to happen right before the desktop is shown. The BSOD always displays wimfsf.sys and a page_fault_in_nonpaged_area error.

Any idea what could be going on? I just installed Windows 7 from scratch a week ago and ran Memtest86 overnight with no trouble. I also tried booting with just one RAM stick at a time, but the issue remains. I haven't made any major changes or installed any new drivers since this started happening. The error pops up even if I try to boot into safe mode or launch startup repair when it is suggested.

Relevant system specs are

Windows 7 Pro x86
Athlon 64 3500+
2x 512MB Corsair ValueSelect DDR RAM
Asus A8N-SLI Deluxe
Geforce 6600GT
Seagate 7200.7 200GB
550W Antec TruePower PSU

I'm not using any additional PCI cards.

Thanks in advance for any help!

    Paste any error codes here as they can tell more about the problem.

    There's also a fair chance that one of your memory modules decided to give up, try running some memtest first (ideally leave it in loop for few hours).
  2. I ran chkdsk with the /f, /r and /b switches to be as thorough as possible and a ton of index entries got deleted, although no bad sectors were found. Still couldn't boot, though. Continuously launching the Startup Repair utility off the Win 7 installation disc then finally fixed the problem, I think I had to attempt 4-5 times before it got nailed, for whatever reason.

    The system is now booting fine, but I want to find out what might be causing these problems. It's not the first time that chkdsk had to make a lot of corrections. It has happened several times recently, so I am suspecting that the HDD is dying. It is slightly over 5 years old, after all.

    I'll try running memtest86+ overnight again, even though I just did it recently. If that doesn't turns up anything, I'll try Seatools once more, even though I, like memtest, ran that very recently, too.
  3. Just to note: The memory is fine and not faulty. I just tagged this thread as solved to close it.
