My laptop stops responding several minutes after windows logon

Help me with my problem. This has been happening for almost 1 week now.

?

I'm not sure if this happened after I cancelled what I am copying last week from a CD. But what happened is stated here: http://www.bleepingcomputer.com/forums/t/502969/unable-to-login-to-windows-after-cancelling-a-copy/?view=getnewpost

?

Actually, after that event, my computer has been encountering this problem (pertaining to the topic title). There are fortunate times that I was able to use my laptop for a long time. Until a while ago, I cannot do anything after windows logon. It stops responding after several mouse inputs but I can see everything is still working (my dropbox is still synchronizing, the WiFi continuously scans for active devices but cannot connect to it although there are and I can still refresh from the desktop).

?

The things that I installed in the past week are Crystal Report and FastReport. I've tried uninstalling both of them from Safe Mode (since I can feel that everything works smoothly in safe mode) but there are error.

?

On FastReport, it says that "The windows installer service could not be accessed. This can occur if the windows installer is not correctly installed. Contact your support personnel for assistance".

On Crystal Report, it says that "Fatal Error: At least one port in the range of 4520 - 4539 must be open for the installation to proceed. Please ensure that no application or firewall is blocking this range".

?

Please help. I need my laptop before August 20 since we have our defense on that day.

I am using Samsung NP300V4A-S02HK running under Windows 7 Home Premium.

Edit: I was able to uninstall the FastReport without a problem in SafeMode (after using the SafeMSI I found here?http://windowsitpro.com/windows/jsi-tip-9233-safemsiexe-freeware-starts-windows-installer-safe-mode?but not with CrystalReport. The same error occurs.
