BSODs (at seemingly random moments)

[3ASUSFan]

Hi!

I've been having these random BSODs for about a month now, and I have no idea what the cause is. The PC runs perfectly fine for a few days and then sometimes just starts having a BSOD several times whihtin a few hours. I've tried returning the PC to an earlier state, upgrading the drivers and it didn't help.

I hope you guys can help me because it's getting pretty annoying.

My Windows 7 did not come pre installed and is downloaded from MSDN. (for further system specs, look @ profile please)

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 0000000000000048, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000001, bitfield :
 bit 0 : value 0 = read operation, 1 = write operation
 bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)

Hmmm, I've had Deamon Tools for a very long time and I didn't start having BSOD's until recently. I'll look into that if the memory test procedure you guys suggested doesn't help. I'll do that tomorrow and report back.

Thanks for the help.

 

[richc46]

Although not included in my report, I suggest that you remove Daemon, too. If needed there is similar software that can be used.
Daemon is a known cause of BSODs and because you did not have them before is no proof that it cannot be the cause now or the future. The immediate cause, however is memory.

 

[3ASUSFan]

Ok, I've left the memtest on overnight and got 13 passes. No errors at all. After I restarted the PC I got a BSOD after several minutes though. I'll try different slots tonight. I've also tried the Windows built in memory and HDD check after restart, didn't show any negative results.

Btw, I remember having the first BSOD shortly after updating the Realtek HD Audio driver. Could that be related? I mean, if it is, you'd see it in the logs right?

I've removed Daemon Tool Lite. Do you guys know any good alternatives?

Freeware MagicISO Virtual CD/DVD-ROM(MagicDisc) Overview

Your reports were all consistent and conclusive, they all point toward memory.
Take a good stick and test each slot.
Did you ever buy RAM? If so did you mix and match?

 

[3ASUSFan]

What do you mean whith a good stick? You mean one which I know is fine? Problem is I don't know which of both is or isn't since I've got no errors in any test. But like I said, I'll try different slots tonight, and I'll also try a single stick in all slots.

And the RAM I've got was a pair (2x2GB). So I could run it in Dual Channel mode. I bought it when I upgraded my whole system in late 2010 (went from AMD 939 socket to AM3 socket).

Thanks for the alternative for Deamon btw.

 

[richc46]

I realize that your memory testing is not over. Take a good stick and test each slot for at least 4-5 pases. If this comes up negative, I have another idea. I have noticed that most if not all your BSODs were caused within the process of svchost.exe
I know from past experience that this is a hiding place for virus. To be on the safe side, run a full, updated anti virus scan and download and make a full scan with malwarebytes. May be negative, but scans can never be the wrong thing to do.

 

[3ASUSFan]

I did the memtest on both stick, in all slots for 8 passes, no errors. Also multiple full system scans, with MSE and no viruses or malware. I reinstalled Windows 7 twice since last time I replied, once on my old drive and once on my new SSD. Since I reinstalled Windows the first time the driver causing the issue seems to be ntoskrnl.exe now. I also just reflashed my BIOS to an older one (thought it might be a BIOS problem), but it doesn't seem to help because I just had a BSOD a moment ago (while typing a reply with an update here -_-, lucky me).

 

[3ASUSFan]

Anyone? Here's an updated zip with the dumpfiles and perfmon.

 

[mgorman87]

Your msconfig shows you have two different video cards. If you are running two then try using only one and if the crashes continue then switch the cards.

That's correct, I've been using the onboard GPU for one of my 3 screens. I had my system hooked up like that since december last year (5 months before first BSOD) without any problems.
I switched the onboard GPU off in the BIOS now and hooked the third screen up to my graphics card.

I've updated my graphics drivers a few days ago, but I got a BSOD about a day later. I've updated them again today.

I enabled the driver verifier.

Prime95 is running the Large FFTs test now, small FFTs ran for 4 hours and 6 minutes and gave no errors. I'll update after I finished both remaining tests.

I finished all Prime95 tests, no errors.

Ok. Also try using only one monitor for the time being.

I've disabled driver verifier just a minute ago (because I had no BSOD after more then 24 running). So far everything's been running stable. I'll report back if anything happens.
