My Winbook J4 laptop shuts down unexpectedly, after several (too fast to count) short beeps. It usually happens when I try to download updates to spy ware programs (Pest Patrol, Spybot Search and Destroy) also when I try a full virus scan, using Avast!. The scan works with Stinger, Pest Patrol or AdAware and comes out clean. Spybot scan will shut down the computer.
I have been in touch with Winbook's tech. support and they don't have a clue as to what the problem might be. The computer is a 2.4 MHz. Pentium 4, Windows XP no Service Pack 2, about 16 months old.
I do not believe that a virus is the problem; the computer never ran without virus protection or a firewall. Any suggestions would be appreciated.
