  1. Oops, a typo - The error message on the Blue Screen of Death should have been DRIVER_IRQL_NOT_LESS_OR_EQUAL
  2. My computer has Windows XP / SP2. It runs for a while normally, then slows dramatically, to the point where it essentially stops. The duration of normal behavior can be minutes to hours, and has no obvious pattern. Windows Task Manager shows no obvious clues. I've followed the directions on the page "I'm infected - What do I do now?" - Ran Malwarebytes, professional edition (which I purchased last year, and which is updated frequently). Malwarebytes reported no issues. - Ran Avira AntiVir, which I also purchased last year. It reported no issues. - Ran DeFogger. DDS.txt and Attach.txt are uploaded. - Ran GMER Rootkit Scanner, several times, under different names, from a few separate downloads. Two types of behavior occurred. 1) The Blue Screen of Death crash dump. This shows DRIVER_IR1L_NOT_LESS_OR_EQUAL ... nvraid.sys - Address BA716E73 base at BA710000 2) The usual dramatic slowdown, but this time showing 100% CPU utilization, with explorer.exe hogging CPU time. The last time this occurred, I killed explorer.exe via Task Manager. My desktop disappeared, but GMER ran for tens of minutes, until the Blue Screen crash dump (above) appeared. During this time, avguard.exe, System, and lsass.exe were using enough CPU time to push CPU utilization high (80+%), but not enough to cripple GMER. I've uploaded Attach.txt (zipped) and DDS.txt (not zipped). There is no GMER log to upload, since GMER did not complete. I've also run CHKDSK and SFC /SCANNOW, and neither showed any problems. Any ideas? Thanks in advance! DDS.txt Attach.zip
  3. Thanks. This is the original poster's spouse, trying to fix things while he's at work. He was posting from my computer anyway (because his is so flaky) using my name. We already have Malwarebytes, and Avira, and I know he's run them, but I will follow instructions and see you over in the other forum, I guess.
  4. Unfortunately, no change in behavior. It runs for a random length of time (as far as I can determine), then slows dramatically, essentially halting completely within a minute or so. So I'm game for any other diagnostic ideas... I will upgrade to SP3 once this problem is resolved. Thanks!
  5. I executed the CHKDSK code above. After the machine rebooted, CHKDSK ran quickly, showing no errors that I could detect before the screen vanished. Next, I executed CMD /C ECHO Y| sfc /scannow from the Runbox, after putting the Windows XP / SP2 CD in the CD drive. This took some time, and I left the room for dinner. When I came back, the SFC progress dialog was gone, and there were no obvious errors listed where I could see. I re-ran sfc from a command window, and again no errors were reported. It looks like sfc is supposed to replace any damaged OS files. Should I assume that is what happened? Is there something else I should look for? Thanks!
  6. Very mysterious. First symptoms were the computer would run normally, for minutes to hours (no consistency), then slow a crawl, then halt entirely. I'd have to power off and on to re-start. Task Manager showed nothing hogging any resources (CPU Time or Memory) at any point. I found some claims that malformed video files might cause this, but there was no improvement after I removed the only video files I'd downloaded in recent weeks. This has gone on for a week. Today, I powered up, saw the machine run CHKDSK, and saw lots of messages saying "Recovering orphaned file" for what looked like a lot of Windows DLLs. Now the computer will boot, then freeze up seconds after I log in. This is Windows XP / SP2. Computer has tens of gigabytes of free disk space, and 2 GB of RAM. Any clues?
