I thought I had fixed the problem but apparently the problem is still there.
First, the basics: I am running a Windows XP (upgraded from ME) on a Compaq Presario notebook. This computer is about 6 years old and have been reformatted a few times. The most recent reformat was performed in May 2005. I didn't actively use this computer until June of last year. This computer has 3 partitioned drives and everything that I keep is not in the main drive (where the O/S is located).
My computer began showing signs of a "problem" about a week ago when it did not respond when I was shutting down. When I clicked on "shut down" instead of shutting down it just showed my desktop. I tried several times with no avail so I just forced it by pressing the power button. That was just the beginning.
The next time I start up the computer, it was fine and didn't give me any problems until I went online. Before I go any further I should mention that I use two different internet connections: one at my own place and one at my parents' place. The connection is fast at my place but at my parents is very slow (even though they're both ADSL).
The problem began when I brought my computer to my own place (which is the first time I have done that) and logged online. The first time was fine, I could log onto Windows Live Messenger and stuff. Then I opened up a file that I downloaded and from then it seems to cause some type of problem that I tried to fix (but I can't be sure that's the cause and I have deleted it already). My taskbar would freeze first (no popups after mouseover on the programs running in the taskbar, can't click on quick launch icons etc.). Also whenever I try to run Windows Live Messenger the computer would lag (sometimes even freeze) and then the program will tell me I can't log on - I tried the troubleshoot and it tells me the connection is fine.
Unfortunately I didn't have any anti-spyware programs installed prior to this problem, only an outdated McAfee virus program. So I went ahead and downloaded all sorts of programs to find out whether I have spywares/malwares/adwares/virus/etc. Found unsafe files, cleaned/removed those. I checked my startup processes and found some malicious program, cleaned/removed that. Checked for virus, found one, got that cleaned/removed. Even checked my registry and removed "extra unused" registries. Also defragmented.
I completed all of the above throughout the week and when I went back to my parents' place at the end of the week the computer and internet was fine when I surfed, except it was very slow and I couldn't log onto Windows Live Messenger. If I don't go online, the computer is fine.
Now I'm back at my own place and the freezing is happening again. Right now as I'm typing this message, I can't access the taskbar again. If I try to click on too many things it will completely freeze the computer and I will have to force reboot it. I have been doing that several times tonight and I still don't know what the problem is.
I hope this is detailed enough. Thanks in advance for any advice and help!
