Lots of BSOD in the past week
Hi guys, first post here, so hello to everyone.
My husband's computer has been behaving erratically for about 10 days or so. It will crash with different BSOD's at random.
Details of the behavior:
- The computer shuts itself down anytime: It can be idle doing nothing for hours, you may be working with it, running programs or not, after it just restarted or after about 12 hours or more.
- The BSOD messages so far have been: "BAD_POOL_HEADER" (mainly on the first few days, haven't seen that one in a while), "SYSTEM_SERVICE_EXCEPTION", a few days ago and twice yesterday, and "IRQL_NOT_LESS_OR_EQUAL" a good few times. Today, for the first time, when running the BSOD Dump & System File Collection app, we had a "MEMORY_MANAGEMENT" one.
-I used "Speccy" to monitor the temperatures and there's no sign of overheating for CPU or motherboard. The graphic card is at around 80 C, but i've read that's quite OK.
- There has been no major new software installed (I think my husband had installed quicktime a couple of days before), windows has been updated, and there have been NO hardware changes at all. There is no hardware connected to the computer except for the USB wireless adaptor for the Mouse and keyboard (see below).
- Technical details: Computer is a Packard Bell Onetwo L A6524 UK.
AMD Athion II X2 220 dual-core processor
23" multimedia Touch monitor Full HD 1080
4GB DDR3 Memory
1 TB HD
DVD Super Multidrive
NVDIA GeForce 9200 graphics
Software: Windows 7 Home Premium 64 bit
The computer is fairly new (3 months old or so), OEM, we haven't done anything hardware-wise, windows updates are ran frequently, and no major software changes done. About three days before the first BSOD there was a power cut here. I unplugged it after the power cut, and only restarted it a good while after power came back.
What I've done so far:
- Ran chkdsk and sfc/scannow, both came clean. (May 31st)
- Removed Avast (and installed MSE) and updated the nVidia drivers (SMU, storage, graphics and ethernet) (also May 31st)
-After that the computer ran normally for about 12 hours, until it crashed again when i re-enabled the power management settings. It crashed at the time it was scheduled to shut down the monitor. It BSOD a couple of times, i disabled power management and crashed again, it was an "IRQL" BSOD, the culprit was "usbport.sys".
- After that it started crashing during POST. It just wouldn't start, once it managed to beep once and then it made a long, continuous beep.
- Then I moved the wireless adaptor to a different usb port and it started normally. After it restarted, I disabled "USB selective suspend setting". No usbport.sys crashes since then. (June 2nd).
-Worked fine for a while, then it crashed again: "BAD_POOL_HEADER", restarted normally for a few minutes, but it froze (wouldn't respond to keyboard, mouse or touchscreen) and the bottom of the screen was "flickering" (like an old VCR having tracking issues). Turned it off, on again, restarted without issues (June 3rd)
- Worked fine for nearly 24 hours, crashed again yesterday while watching a youtube video in fullscreen (we had been watching videos for a while, without any problems).
- Since then, it's crashed a couple of times. Last time was the "MEMORY MANAGEMENT" one I mentioned above.
- Ran Dump & System File Collection in safe mode. Then restarted and ran System Health Report in normal mode.
- Saw something about the mouse in the SHR, checked the drivers, found 2 mice (?), disabled one, checked for updates, it said the drivers were up to date.
I'm attaching SHE report, Dump & System File Collection report, and the whole minidump zipped folder in case you want to take a look at it.
Thanks for any input you might provide. I can find my way around a PC, but please bear in mind I haven't used Windows in a couple of years, so please anything you need me doing, explain it to me as if i were 5 years old, cause it takes me a long while to find my way around W7 :)
