random BSODs

[aros]

I recently got mainboard replaced in my Dell Vostro 1500 laptop due to soundcard fault. After replacement I also bought a new 500GB Seageta HDD. I did a clean install of W7Pro 32-bit and now I get random BSODs. My laptop came with Vista HB but before mainboard replacement I had W7Pro installed with no problems - using drivers from Windows Update, working fine and stable for about a year - until soundcard fault.

I suppose it could be mainboard, memory, faulty driver or HDD but I don't know how to analyze my BSOD's and crash dumps. Please help me

My system came with Vista HB 32bit, 160GB WD HDD and 1+1GB memory, now I have W7Pro 32bit (from MSDN AA), 500GB Seagate HDD and 1+2GB memory.

Please remove any CD virtualization programs such as Daemon Tools and Alcohol 120%. They use a driver, found in your dmp, sptd.sys, that is notorious for causing BSODs. Use this SPTD uninstaller when you're done: DuplexSecure - Downloads
You can use MagicDisc as an alternative.
