>>>>In my case the BSOD, I think, is caused by memory but not necessarily faulty memory chip (I used the utility you recommended and it found no fault). What I see before the BSOD "fires" is my screens go haywire; they start jumping around, size changes, go On and Off. This goes on for about 5-15 seconds and then very quiet :).

>>>A video problem like that could have several causes:
>>>
>>>1. Bad cable connections if you're using more than 1 monitor. Try to avoid "converters" in cables e.g. DVI to VGA. Try to use digital over analog connections e.g. HDMI better than DVI better than VGA
>>>
>>>2. Bad video driver. Try using the latest from Windows Update or your computer manufacturer (Dell, HP etc.) or chipset maker (nVidia, AMD)
>>>
>>>3. Bad video adapter hardware. All adapters have a controller; if you have a so-called "discrete" adapter it will also have its own video RAM rather than using some of the main system RAM. Either a controller or video RAM failure can cause symptoms like you're seeing.

>>>4. There is a small chance a secondary monitor (if you're using more than 1) could cause problems like this. If you can try a different secondary monitor, do so. If not, try running with just 1 monitor for a while - longer than it would normally take to generate a BSOD - to see if that makes a difference. If the BSODs go away, it could be the secondary monitor, or software/drivers that support multi-monitor operation.

>>All good suggestions. Interesting that when I had BSOD with Aventail VPN it was ONLY when I am at work where I have two monitors. But the BSOD with VS2012 happened only when I was at home where I don't have second monitor (just the one on the notebook). I will have to carefully go through all other items and check. And I am not that savvy on IT issues so it will be a challenge. Thank you very much!

>>P.S. The computer I am using is 3.5 years old. Maybe time to buy a new one.

>There are trial versions of SiSoft Sandra and Everest available. Assuming the trial versions don't disable the functionality, you could use them for hardware diagnosis.

I will Google these names and check it out. I am always concerned (call me paranoid) of installing "tools" as they may make changes that make situation worse. Thank you.
