Windows 7: win7 pc crashing

win7 pc crashing


My apologies if I have not supplied enough info. or conformed to any of the rules. My first post/thread. I have had my win7 desktop for a couple of months and it has been relatively ok. It had crashed several times but recovered, I suspected ssd drive was causing problems as it disappeared from bios when I tried to boot from it. I have got a replacement from the pc supplier but in the meantime I had been running from a ide drive that I had attached to the MOBO. Fortunately I had taken an image of the OS before the ssd was determined as the problem. I have been running ok for several days without any problems but this morning pc crashed. I consider myself reasonably competent with computers this is way out of my depth and I would be VERY Very grateful if you could help me.

I am attaching files requested for BSOD but the seems a little large after compression.

Many thanks Carl.

Hello Mister Smith, welcome to SF!

Are you running MSE, or, if not, Windows Defender?

If so...It could be there is a conflict with earlier/other AV files.

But chances are there is something wrong with your memory. Please test:
Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program.

Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

RAM - Test with Memtest86+

As this test circumvents W7, it'll tell us something on HW/BIOS.

Hello MvdB,

Thankyou for your welcome and swift reply.

Yes I do run MSE. I also have winpatrol running and I was wondering if this could cause problems?

I will run the memtest, again, many thanks for your help.

Well, that is a matter of opinion and, I guess, not really an exact science. In this forum you'd probably find a lot of different opinions on that. From personal experience I can say that Avast! in combination with Malwarebytes Anti-Malware is a proven combination. I do know that these combinations can prove to be tricky. I'd say, just test it, don't risk it. As a test, remove winpatrol (make sure you can reinstall later) and use Malwarebytes, (again, only as a test) to see if that makes a diff.

tried memtest

I think that winpatrol and mse will tolerate one another...but what I think is more significant is memtest failed! I was not expecting that. It threw up errors with both modules in 2x2GBs so tried testing individual mem in different slots. The results were a bit conflicting but I can get both modules to pass (only 1 pass) in certain slots. I then tried swapping the modules around from there original slots and this passed, albeit again to 1 pass. I am starting to think that the bios setting might be putting this configuration a bit close to the edge.

I realise that overnight testing will be more conclusive and I will do that tonight.

I would be grateful for your opinion and any further advice you might have.

Many thanks, Carl.

I know it takes a long time but if in doubt it is wise to follow the tut on memtesting to the letter. The thing is that an error can be from a stick and/or a slot. You need to figure out which it is and it could be both....

Thanks Mvdb,

I realise to conclusively test memory it needs to be "soak" tested. With the modules swapped the system ran for 10:17 hours and did 12 passes without error. I think the timings are very critical and in this position it works fine.

In the past the system crashed very intermittently. I am not sure how win7 copes with those memory errors and I am surprised it performed as well as it did. Hopefully this is the resolution to this. I run my business on this computer and these sorts of faults really eat away at the time.

Thanks very much for your help. I hope this has cured it.

Hope so too Carl, specially if you run your business on it, it's way more critical than a lot of the situations we encounter here. Please be sure to have a W7 Repair disk and backups up-to-date. At the end of the day, IF something really goes belly-up... you can always easily rebuild.
System Repair Disc - Create

This would help repair but does not do clean installs, you have your W7 DVD for that + your backups...
