Intel D865 mobo won't boot

I have an Intel D865Perl motherboard which is about two years old. It
was working fine until it wouldn't boot one day. Nothing happens when I
push the start button.

I did the following test procedures with no success:

1. Turned off power supply for several hours.
2. Tested the start switch by jumping it's terminals on the motherboard.
3. Reset CMOS with a temporary jumper.
4. Removed CMOS battery for an hour.
5. Tried another power supply.
6. Tested power supply by installing it in another computer. Works fine.


The green LED power indicator on the motherboard still lights up, so the
board must be getting power.

I noticed that one of the IC's on the mobo is very hot. I touched it for
a few seconds and almost burned my finger. The other IC's are at room
temp' or slightly warm. I identified the hot IC as the I/O controller
which is a PC87372. Is this the likely cause of the no boot condition?

The following JPG shows the I/O controller chip in the lower right hand
corner, near the ATX power plug socket.

TIA

It shouldn't be that hot so I'd say it's bad and that would sure prevent a
boot as one of it's functions is power control.

What caused it to go bad I couldn't say for sure but it also contains
legacy functions like floppy controller, parallel port, serial port,
keyboard, and mouse controller, which makes it vulnerable to external
faults like static discharge should it get through the ESD protection
circuitry.

yep i agree...
you might as well replace the motherboard.

you'll probably have to perform a repair installation but you should be able
to
keep your OS pretty much intact

The computer wasn't used for a few days. During that time we had some
thunderstorms with a lot of lightning. It was after those storms that it
wouldn't boot. The other equipment like the monitor and printer seem to
be OK.

Thanks

I figured the motherboard was probably toast. Can you suggest a
replacement board that will accept the same CPU (assuming it's still
good) or a newer version of the P4? I'd like to use the same memory but
I guess I won't know if it's undamaged until I try it in a new board.
I've never done a repair installation with Win-XP. What does it involve?

Thanks

Maybe you could find a fairly similar board on ebay???

The lightning storm is a likely suspect.

Whatever blows first acts as a 'protector' to the rest and Murphy's Law
states it'll be the most expensive device.

There was someone on Ebay selling a lot of 50 D865PERLX's (I bought one)
last month. Price was $54. They do come and go on Ebay. Just check the "AA"
number to make sure it's compatable w/ your processor.
