no matter what i'm doing eventually it freezes up i cant reboot i have to turn off the pc by hand

You should check out your event viewer to see what's causing the lock up. Sometimes it's a driver problem so you should check out your device manager to see if there are any faulty drivers. Here is a hard drive fix and scan instructions page below has a few more tips: 1. Click the Windows button or Start and open the Computer folder. 2. Find and Select your hard drive, right click the hard drive icon. 3. Choose Properties from the drop down list. 4. In the Local Disk Properties dialog box, click the Tools tab. 5. Click the Check Now button. 6. For maximum cleanup click "Automatically fix..." and "Scan for ..." 7. If you see new dialog window, click Schedule disk check to start.

It could be that you have a virus or bad memory. http://www.memtest86.com/ Boot off that and let it do a couple of passes. If you have even a single bad bit you need to get new memory.
