Help my computer keeps freezing up and acting weird on me?

Unplug the computer. Remove the cover. Using canned air (available at walmart in the computer department) blow the dust and debris from the CPU cooler. The fins of the cooler are most likely clogged with dust causing the CPU to overheat and freeze. Also clean the video card/chip cooler if you have one. Good Luck

This is because of the computer’s registry. The registry is a very complex and often misunderstood component of Windows. It’s vital to your computer’s operation. Think of the registry as your computer’s brain. And everything you do on the computer, everything you install or remove, is stored in the brain. When you remove things, very often certain registry entries are left behind, like memories. But these memories are good for absolutely nothing. The registry hangs on to them, though, and eventually it gets so full that it’s hard to find things that are important now. The registry is probably the culprit if your computer freezes randomly.Consequently, one of the best solutions in managing the situation is to use registry cleaning tools http://best-way-to-improve-pc-performance.com with great power and capacity to completely flush out all junk files and fix all errors found.
