Windows 7: BSOD Random-Guessing Hardware Conflict

Software most often in use - AutoCAD 2013
The machine is a new build.
I have been getting some intermittent AutoCAD crashes as well as Firefox.
Not too often but I have had a BSOD or two over the past few weeks. Then in the past week or so, while I wasn't even on the machine, the machine crashed.
Just today for example I reset the machine and let it sit at the login screen. The computer sat there for about 30 minutes untouched then bam! BSOD.
Most days no problem at all.



Thanks in advance.

You have given us quite a few BSOD reports. They all indicate different drivers. The usual cause of this is hardware. Most of the time it is memory problems. Test memory with memtest86

If you run for 8 passes and then run each stick in a known good slot for 6 passes and you pass, we will administer other hardware tests.

Great! Thank you for the info. I will start with the RAM.

You are very welcome.

I discovered that one bank (4 gig) of my memory was bad. I pulled it out of the machine and so far I have had no BSOD occurrences.

Glad that we may have sorted your BSOD problem so quickly.
