I have an HP desktop A1700n with Vista home premium. For the last month or so the system freezes about 2 minutes after it is turned on. It always happens and freezes for about 2-4 minutes. The only thing that is active is the cursor while it freezes. I have looked at anti-virus software, start-up processes and have talked with an HP technician. Their last recommendation was to reload the system, which I don't want to do yet. I have 1 hard drive, 2G ram and a DVD drive.
