Yes I saw your other post. The reason for turning off wake-on-LAN was 
not a security question, rather that if not properly implemented, it can 
cause this problem.

Back to the major problem.

Power off the system, let it cool down, remove all external cables, open 
the case and check there are no points of the motherboard that could be 
touching the metal case where they shouldn't be (ie shorting out). Look 
very carefully for any burn marks on the board.

If you have an anti-static strap, put it on your wrist and connect it to 
the case so that you are at the same potential. If you have no strap, 
make sure you are always touching the case with one hand while touching 
components with the other. Now remove all plug in components, including, 
cables, adapter cards,  memory DIMMs. If you are skilled in this area 
and have some heatsink paste, also remove the processor, Make sure all 
sockets contacts appear clean and no pins are bent.

Now re-assemble everything, ensuring everything "clicks" into place - ie 
dont force anything but everything should "positively" sit in their 
connectors. Where possible put components in different sockets - eg 
memory DIMM pairs in opposite sockets, PCI cards in different sockets.
Make sure once more that there is nothing now on the motherbord that is 
touching the case that shouldn't be.

Close the case up and re-attach all external cables. Turn the system on 
and go into the BIOS setup, select reset to factory defaults and allow 
to re-start.

Now see how you go.

If the problem still exists, power off, open the case again and remove 
any components that are non-essential, for example if you have four 
memory DIMMs and the system can run with two, remove two. If the DIMMs 
in use go in single rather than pairs, go down to just one DIMM. Remove 
any adapter cards that are not needed for the system to boot up, eg the 
network card.

Once you have the system in the "base" configuration, see if it boots 
without any hardware errors (you'll have driver load errors for the 
components you removed of course).

If there are STILL problems, try exchanging the memory that is still in 
the system with the memory you removed (if appropraite).

Hopefully at some point you will again have a stable system. At this 
point power down and start putting the "non-essential" components back 
in one by one. Once the problems return - you know which component is 
causing the problem, replace it.

Good Luck

Cheers/2

Ed.
