Disconnect ALL of your USB devices and see if that solves it. If you have USB keyboard or mouse, get a normal PS2 or serial mouse. It maybe linked to USB. Alot of times this maybe a bios problem. Try flashing the bios (disconnect all uneeded periphs). If none of this works, go into the bios and disable L1 cache. See if it solves this, if it does the CPU is probably the problem.
If you argue with an idiot he will drag you down to his level and beat you with experience.
