Hi. I post this thread due to three blue screens in the past week. I didn't actually see the "blue screens", for i was afk, but the moment i came back, i saw the login screen and a windows message saying the system had blue screen and booted. I generated a debudlog.txt but can't really understand what it says - I hope i can find some help here. I run Windows 7 Ultimate 64-bit (6.1, built 7600) Intel Core i5 CPU 760 @ 2.80GHz (4CPU's), ~2.8GHz 4GB of RAM (p.s - right after the last 2 boots, my network adapter IPv4 settings has changed - mainly the default gateway and DNS. This has never happened before. Can it relate to the DHCP server i installed yersterday?(tinyDHCP;which i didn't encountered any problems with.) ). Thank you, Ron.
