I found out that the protection for preventing the Motherboard from burning did not work and the processor burned out. I replaced it and solved the problem.
Feature taken from the Motherboard manual.
Built-in hardware monitor function will monitor and protect your computer which is the special design in hardware for protecting Pentium 4 CPU from burned, and will shutdown power supply automatically when CPU is overheated or the CPU cooling fan is not working.
WELL, the motherboard is "protected" and I can not unprotected. The hardisk led stays on and the computer in HALT "DOES NOT DO ANYTHING".
What I've done:
1. I disconected the battery, the hardisk, the processor the display card, the jumpers... THE H/D LED STAYS ON.
Motherboard: Machspeed TP800BDP
Processor: Intel Pentium 4 3.0 Ghz
What can I do? HELP.
