Ntoskrnl.exe - constant restarts (BTW, Memtest passed)


New Member
I've been facing constant problems with BSOD (Ntoskrnl.exe) today. It happened for the first time about a month ago when I tried to update Opera (12.16 -> 17.0) but after many, many restarts, trying to run Windows in a "Safe Mode", restoring recovery points finally Windows started to work.
I haven't tried to update Opera since then.
Today... I don't know what happened because I went away of a computer (yes, guys, it's possible ;)) for a few minutes and when I came back I saw BSOD with 'DRIVER_IRQL_NOT_LESS_OR_EQUAL' error. I tried to find a solution on the Internet but I still don't know what else to do.

When I run system in a Safe Mode with a 5th option (Safe mode with networking) everything works but when I try to run Windows normally - same situation as previously (reboot)...

I added dump file as an attachment (111313-10140-01.txt).
Please change the extension (txt -> dmp). I wasn't able to upload .dmp file to this forum. The second file (debuglog.txt) was created in a following way:
Type the following:
kd –z C:\Windows\memory.dmp (or the path to your .dmp file)
Type the following:
.logopen c:\debuglog.txt
Type the following:
.sympath srv*c:\symbols*http://msdl.microsoft.com/download/symbols
Type the following:
.reload;!analyze -v;r;kv;lmnt;.logclose;q
I found above-mentioned steps on Reading a memory.dmp or other .dmp file - Scott Forsyth's Blog The last but not least... About a month ago (when I had the same problems) I run Memtest for a whole night and it found no problems. I haven't tested other hardware yet.
Please help me with this issue.

Thanks in advance.
