Freezes, BSOD IRQL Not less or Equal 0x0a
Hi,
Approx. a month and a half ago my computer started randomly stalling when idle, at first 1-2 times a week and then daily. After some time, it started only stalling 1-15 minutes after boot, and then would run perfectly fine for hours if it got past that first period, even if idled.
In the third week, I started getting the following BSODs - Irql not less or equal 0x0a, Page fault in non paged area and eventually also System Service Exception (targeting tcpip.sys). My computer is set up to save small memory dmps but it only has one dump from /08 and it is not saving them when it BSOD's. Sometimes it says that it has saved the data on the screen but there's nothing to be found after or it gets stuck on Collecting data...
When the computer freezes, basically it comes to a stall and doesn't respond to the keyboard and mouse (keyboard does not register input at all if locks are pressed etc.). This has happened also in safe mode, but only once. Sometimes now, it auto-restarts rather than freezing. Crashes are intermittent, there can be days where it boots and runs OK. If it doesn't crash within 20 minutes of being started up, then it's fine until rebooted the next day.
So far I have:
- Cleared some misc errors from event log which haven't had any effect
- Run memtest to test the RAM (Passed)
- Ran chkDisk, startup repair & memory diagnostic (Passed)
- Uninstalled avast! & installed AVG
- Scanned for virus/malware and cleaned registry
- Checked nothing has problem icon next to it in Device Manager
- Updated video drivers a couple times, checked Dell/Intel site but not had any recommended driver updates suggested except one which turned out to be older than my current version; I'm not too sure when it comes to non-video driver updating, I've never had any driver-related problems and needed manual updates for a PC before.
Install/Update history: It had been about a week at least since I installed any new software on the PC as far as I recalled, and there were recommended/important Windows Updates auto-installed the night before it first started freezing up.
I am not having much luck tracing the cause of the freeze & bsod (freeze is much more common) because I can't get the dumps to save. I am guessing this is related to the particular problem/s my PC has. I have attached the .rar from SF Diagnostic.
Any help/advice is most welcome and appreciated
Thanks
Fay
