My computer continually freezes for 30 seconds to two minutes. It does not matter which programs are open or in use. All of the software updates are current. I have completed repair option on several of the programs, with no affect. I have ran regtool, cccleaner, hard disk check, ram check all to no avail. I can not run vista repair because my vista disc does not have the sp2 installed.

Not sure what to do next. Please help.
