HP Laptop Freezing During Startup?

I've had issues with this thing for awhile but for the sake of the forum I'l stick to my current issue.Upon startup, everything works fine. I put in my login password and Windows begins to load. While Windows is loading it just reezes. The only thing I can say is it freezes after most of the applications load but it's still searching for networks. Straight freezenothing works. However, and this was weird, out of the 4 or 5 times it froze last night, one of the times I was still able to move the mouse. Nothing else worked though.My drivers should be up to date. I do check them and update them as needed.I do regular checks for viruses and spyware. I use free programs that are updated regularly.I "clean up" my system on somewhat regular basis.I defragment the hard drive on a somewhat regular basis.I clean my registry regularly.I deleted the programs that start up with the computer that I don't need. Winamp, my spyware scanner, and this clean-your-PC program I downloaded (see below) no result I recently got suckered into one of those clean your PC programs that cost like 20 bucks. That's the only major program I've downloaded recently. I did a system restore to before I downloaded that and the same problem occurred.The computer works fine in safe mode. Even "with networking" it connects to the internet just fine.I did just realize I didn't do a virus scan in safe mode last night, I'll do that when I get home tonight. But if you guys know a good free virus scanner to use let me know, otherwise I'll follow up if the virus scan fixes it.
