I honestly do not know what to do anymore. My desktop and taskbar freezes as soon as everything(icons, etc,) loads after startup. A lot of times the desktop freezes and I can't click on anything but when I move the mouse down to the taskbar I get the hourglass but it'll just stay like that even if I leave the computer on. I have tried scanning for spyare, malware, viruses, registry....found nothing major. I'm starting to think it may be a hardware problem or something. Everything is fine in Safe Mode though, there is no freezing at all. I have tried using system restore to restore to a time when I know for sure the computer was alright and then the freezing would be gone on the startup right after the system restore but the next time I restart the computer the problem returns.
Now system restore is not fixing it anymore - even when I restore to a previous time when there was no problem the freezing will still be there. I initially thought it was because of windows service pack 3 causing the problem but after system restore I didn't allow it to be installed and the problem is still there. I haven't downloaded or installed anything that I know of before the problem started; it is as though it suddenly appeared out of nowhere. The only thing I haven't tried is the full system restore which deletes everything and restores the computer to factory-settings. But that is the last resort.
A few days ago, after leaving the computer off for several days, the computer started up perfectly fine but while I was surfing the internet the taskbar froze while the desktop was completely fine. Some other times if the desktop does not freeze I can open folders but I can't open the programs.
