Hi, I did a clean install of Windows 7 x64 about a week ago and have been having the freezing problem as well. Here are my system specs: Intel Core 2 Duo E6850 3Ghz chip Asus P5KC motherboard 4 Gigs of Corsair DDR2 XMS2 ram BFG 7900 GT 512MB GDDR3 Video Card Like everyone else it started out great. Then Windows installs the updates and it starts freezing every 5 minutes. I have read through the whole thread here, tried the power fixes, bios settings and driver fixes, I reformatted and reinstalled windows multiple times, uninstalled my anti-virus program, took out some of my ram (because of possible conflicts with the vid card), got rid of all but the essential programs for me. My event log currently has 44 errors and critical events ranging from dns client time outs to print service issues. I am trying very hard not to go into a full on rant about Microsoft right now but I am really frustrated! Especially since there are so many possiblilities about what could be causing the problem! Thanks for all of the guys offering help here. Please, if you have any ideas let me know before I do the unthinkable and change my loyalties!
