Had a few blue screens lately. I was experimenting with old Firewalls on my XP such as the likes of Kerio & Sygate & Tiny etc. Most sooner of later gave me a blue screen. At least I think it was the FW. When I un-installed all was fine again. But there's been other times when you're scratching your head as to why you're staring at a BSOD. Or even one of those start-up pop ups that say such & such had to close etc. Them & the BSODs come with secret coding to explain to geeks the secrets of artificial life. how does one go about finding out what those coded messages with lots of zeros and numbers mean as to why the PC crashed?
