My computer suddenly became slow two days ago, without any apparent reason. I thought it was a malware or something like that, so I formatted my computer, then reinstalled Windows 7 with the official CD, but it still is really slow! I checked my HD with HD Tach, my memory with Memtest86+, and everything seems to be OK. I ran an Hijackthis scan, and here is the log: http://pastebin.com/hXGzt6H8
If someone could help... I really don't understand why it is running so slowly! (the "missing files" in the hijackthis report are - from what I found - an error with HJT/Win7
Thanks in advance!
