New Laptop BSODs

Hi everyone. I recently purchased a new laptop, and I've been getting BSODs. I thought it was a RAM issue and ran memtest86. All seemed good. So I ran Prime95, got errors the first time, but upon testing the RAM individually and then in opposite slots, I got no Prime95 errors anymore. The BSODs have returned, and no tests I'm running are giving me negative results. I'm very grateful for any help you can offer!

What Anti-Viruses have you had on the laptop since you got it? (incl. ones that you have uninstalled)

3 BSODs - all Microsoft Drivers; meaning that it is most likely a hardware error.

One suspicious 3rd party driver that was loaded at the time of all 3 BSODs

Code:

smserial.sys Mon Dec 01 22:45:22 2008

smserial.sys - Dial up modem driver. Update from your laptop manufacturers website.

Also, given you got errors on at least one memtest try running it again for an extended period this time (at least 7 passes per stick)

Regards,
Reventon

I've only installed MS Security Essentials.

Those are the latest Modem drivers, but I'm not exactly using it- can I just disable the device or should I fully uninstall it?

I'll try running an extended memtest again. :/

Thanks so much for your response. :)

Ok, the reason I asked about the Anti-Viruses was because in one of the dumps MpFilter.sys was mentioned:

This driver is part of Microsoft Security Essentials, and while we do see 3rd party Anti-Viruses as the cause of BSODs all the time it is unusual for a Microsoft Driver to be the true cause.

One of the possibilities in the above case is that remnants from a previous AV install could be interfering with MSE, but obviously that is not the case. The other possibility is hardware error.

After you finish the memtest run Prime 95 again following these instructions:

Prime95 Setup:
Download from: Free Software - GIMPS
- extract the contents of the zip file to a location of your choice
- double click on the executable file
- select "Just stress testing"
- select the "Blend" test. If you've already run MemTest overnight you may want to run the "Small FFTs" test instead.
- "Number of torture test threads to run" should equal the number of CPU's times 2 (if you're using hyperthreading).
The easiest way to figure this out is to go to Task Manager...Performance tab - and see the number of boxes under CPU Usage History
Then run the test for 6 to 24 hours - or until you get errors (whichever comes first).
The Test selection box and the stress.txt file describes what components that the program stresses.

Well, after 10 passes, the first stick finally got 2 errors. "There's the culprit!" I thought. I ran the second stick and by the time 7 passes were over it had over 4000 errors. I'm going to RMA both sticks. Should I still run Prime95?

Thanks so much for your help!

Agreed, if a memtest fails it does not necessarily mean that the RAM is faulty - it could be the motherboard. No need to run Prime95 now.

There are two DIMM slots on my motherboard. At the recommendation of my manufacturer I'm going to RMA the whole unit and let them give it their workup.
