Toshiba P205 running win7 for 2 weeks. Normal upgrade with no problems. Today computer will not run properly. Takes 3to 4 min to run a command. When task manager openned monitored cpu usage. Normally when you ask for a tasked cpu jumps up then back to zero. the opposite happens cpu at rest is about 49% when tasking to open anything even a simple command the cpu drops to zero and the computer locks up for 3 to 5 minutes. Ran in safe mode everything run great. Restarted computer with minimum services and no start up programs. Same problem. HELP???????????????????
