As on my experiences of being a technician for almost more than a year, BSOD is not a bug nor a clean memory. This is refer to an area within the RAM or HDD which is damaged(i dont know what is the exact term) or a faulty driver, meaning its an issue in hardware and software. This is usually happen upon loading system files. Initial files are loaded first into memory and when those files are not loaded then the BSOD will appear.
You should consider also the cleanliness of your memory bank and memory module. They should be free from dust to prevent lost connection. Use air compressor and lighter fluid as cleaning material.

Good Information regarding RAM,HDD, UPS and AVR. But one thing which always pinches into my mind is, what exactly this "BSOD". Is that a Bug or else a clean memory idea. I would really be thankful to you if you send me a snap of it or else get that posted on to your website. Thank you in advance,
