I have a user with an HP Probook 6550b Windows 7 64bit, 8gigs of ram in an AD enviroment. When he first logs in, laptop runs perfect. After about 1 hour to two hours on the network the laptop starts to bog down. Laptop has had the motherboard and processor replaced, memory replaced, and hard drive replaced. It has also been reloaded 4 times as well. Below i have the hijackthis log from in the morning, and after that one the hijackthis log when the laptop is very slow. Any feedback would be greatly appreciated.
Mod Edit: Removed HJT logs, not to be posted in this forum since this forum does not deal with malware. See No DDS, HijackThis, or ComboFix logs - http://www.bleepingcomputer.com/forums/forum-167/announcement-45-no-dds-hijackthis-or-combofix-logs-should-be-posted-in-this-forum/ . Issue seems unlikely to be malware, based on all hardware changes detailed, IMO - Hamluis.
