Windows 7: BSOD started during Skyrim, now random

Hello forum,
This is my first post here, I hope I post it so, that you will be able to help me.

My computer started crashing a few days ago, in -what I believe- the same manner as it did a couple of months ago. After a long search i finally found that my SATA hard drive was connected to the 4rd slot. I reconnected it into the 1st slot, which was the end of my BSOD's and crashes then. Untill now.

Now it started while I was playing Skyrim, which to some point I can imagine: it's a 'heavy' game and takes some effort from my pc. After the first crash i started monitoring my temperatures while playing (skyrim on my one monitor, speedfan on the other). My CPU temp rose to about 51 degree Celcius. The crashes occured a lot after I got back from afk. I use an Nvidia Geforce 220 GT, which I updated last week orso. Frankly, all the trouble started after I updated it, not sure if that´s of any significance.

After a while the crashes came also while i was just on youtube, or afk from my pc. Sometimes with bluescreens saying: IRQL_NOT_LESS_OR_EQUAL. But not always.

I don't know if all the codes are attached in the file, but two individual BSOD codes occured, which I have been able to write down:



first:

124
0x0
0xfffffa8005150078 (not entirely sure about that 7, couldnt read my handwriting..)
0xf6052000
0x2c000128

second:

124
0x0
0xfffffa8004D3C028
00000000B651A000
00000000FF000128

The attached System Health Report is in Dutch, as that's the language of my pc. I hope it will somehow still be of use to you. I will be happy to translate stuff.

My OS is Windows 7 home premium 64 bit, original full retail version. My pc is about 1,5 year old, with new memory slots (or new motherboard, not entirely sure, since i send it to the manufactor) of about half a year old. Since the 1,5 year I got my pc, I haven't reïnstalled it yet. I also use an external hard drive of about four years old.

It´s a long post, I hope I was as accurate as possible. I hope sincerely that someone can help me, since it isn´t the first time I´m having problems with this computer.

Thank you in advance!

You have a hardware error (0x124). Read the following thread and see if any of it's fixes work.
Stop 0x124 - what it means and what to try

Among the fixes in the above thread are a number of stress tests. These are tests that will 'stress' a specific hardware component to check for any defects. To make it easier, I'll post the main stress tests below (RAM, Graphics Card, CPU, HDD):

Test your RAM using Memtest86+. Let it run until 6-8 passes have completed or errors have been found.
RAM - Test with Memtest86+

Test your video card using Furmark. Watch your machine's temps and stop the test if it starts to overheat or artifacts appear on the screen.
Video Card - Stress Test with Furmark

Test your hardware using Prime95. Watch your machine's temps and stop the test if it starts to overheat. Let it run for up to 2 hours or until errors have been found.
Hardware - Stress Test With Prime95

Run a chkdsk on the system partition to check for bad sectors or system errors.
Disk Check

If you are overclocking, STOP. Reset any changed values back to default.

Have you recently installed or replaced new hardware?

In November I replaced the video card. Where can I actually check if I am overclocking my cpu?

If you were overclocking your CPU you would know. It's something you have to do manually so unless you remember doing anything of the sort, you should be fine.

It could be the graphics card then. Run Furmark first and see if any errors pop up.

Ok, thnx. I haven't manually overclocked my cpu, so thats fine, I guess. I'll run the video card thing as soon as my memtest is done a couple of times.

Hmm, I ran FurMark, my temp was around 55 degrees celcius max. With 2 fps with the first visual test, after I hit the space bar it went up to 66 fps, with a small temp drop of a few degrees. So that means my GPU is ok, I guess? I ran it for 10 minutes or so, after that I stopped because there was no change or any major fluctuation.
Memtest didnt point anything out. And I scanned my HDD with HDAT2, which my neighbour recommended, at the max test, there were no problems.
I also scanned for virusses, no problems there. The last thing for now to check is my processor.

Yup, just use Prime95 and post back with the results.

Hello.

Not sure if I'm supposed to start a topic when I'm posting again. So I'll just try and explain everything here on my first topic, to avoid double posting. I hope it will still get through.

Seeing everything i tried in the above didn't really point out anything usefull, and because of losing the time to fix it, I eventually stopped looking for the problem. The BSoD's and problems stayed, however in less severe form. Now I finally have vacation, and I decided to finally reinstall my windows, because I hadn't done that yet. Now the problems actually worsened. I do not know if this is because I have more spare time, so am able to get on my pc more, or because i reinstalled the pc.

Anyhow, the last two days its been so hard, that I can't function properly on my pc anymore. I will try and summarize the different problems and hope anyone can see a pattern. (I warn in advance: none of the problems are definite. There are times when it goes easier, and there isnt one single action for me to be found which pinpoints a reason for the problems)

At first, when starting up my pc the first one or two attempts don't work (most of the time): my screen stays black, while my fans and such begin running. I have to manually shut down the pc and wait a moment to try again.

The last two days my pc boots right away but I get the warning that the "DQS training failed on previous boot, reverted to lower DRAM speed". Then it forces me to enter the bios. I do not know what he wants me to do in there, so I look around a bit, when (twice already) my pc freezes in BIOS (wtf?!)

Ok, so then I manually reboot my pc (again) and try anew. Sometimes I'm finally able to get to windows. In my relief I try to start up a game whcih eventually follows up in a BSoD (the last time was during Age of Mythology, which doesn't have such stunning graphics to challenge my video cart.

Today I did not bother yet to start up a game, this time I only tried to chat with some people on Teamspeak. Even then, after me saying "hello, how are you?" i get a Blue screen.

The new thing about these recent events is that I finally get some new BSoD's. So far I've encountered: something with DQS training, Bugcode USB "control" (or "driver" don't know for sure), Bad Pool Header, Bad Pool Caller, System Service Exception, Memory Management, IRQL NOT LESS OR EQUAL, DRIVER IRQL NOT LESS OR EQUAL.

I'm trying hard not to make a sarcastic comment about my collection.

Anyways, I hope you can see something in my case. If not, should I just go to some pc repair guy, and say:"Hey, it's broken, can you fix it?" Because I'm getiing a bit hopeless from the situation.

I hope I informed you enough. Thank you in advance!

Yours, Kasper

Any driver issues usually disappear after a clean install which leads me to believe that this is a hardware issue.

Try switching the graphics card out and rebooting. If you have onboard graphics simply use them but if not, try using a card from a different computer.

Isolate each RAM stick and reboot. If you can, run Memtest86+ on each stick desperately.

Finally, I have result! I have tested both my memory cards in the first slot now, which gave no errors. But, now i put one of my cards in the second slot and i get 6144 errors so far. All in the third pass in test #7.

While i'm typing this suddenly the errors flood. 45000 now and still counting.
