Try shorting the cmos jumper. If theres a problem with the real time clock
it could be the cmos battery is dying.

Unplug the computer, as instructed in the manual.

The manual says "Avoid clearing the CMOS when the system is on".
If using the JBAT1 jumper, unplug the computer before using the jumper.
If you don't follow that instruction, a certain dual diode on motherboards
can be damaged. (Not all motherboards are prone to that problem, but
good practice is to unplug when using jumpers like the JBAT1 jumper.)

The only time the computer should be powered up, is when the jumper is
in the "keep data" position, shown in the manual as jumper on pins 1-2.
The jumper is probably in that position right now.

Also, I found a thread here, which may be for that board. When
you have the side cover off the computer case, check for bad
capacitors.

Presumably, it takes execution of some BIOS code, to make the display
change from the red-red-red-red initial display value. That doesn't
necessarily mean the processor is damaged. For example, pulling out
the BIOS chip (if it was socketed), would also leave you with four reds.

The same thing happens with a PCI Port 80 debug card. If the display
stays at 0x00 or 0xFF (whatever its initial reset value is), then
you'd assume that no BIOS code got executed, for some reason.

Do you get the same symptoms with all RAM missing ? Strip the system
down, so that less hardware is present, and work your way back.

For example, if there is the processor still in place, and other
hardware is disconnected from the motherboard, then if the processor
is working at all, the LED display will be updated with an error code.
I use the same advice for boards without LED indicators - you can
remove RAM and video card, and try to get the motherboard to indicate
a RAM or video card error. It is a way of proving that a little of the
hardware is sane. The RAM test happens before the one for the video
card.

In terms of the RAM that was added, does it look OK ? No marks
on the gold fingers, or damaged components on the DIMM ? Have you
tried verifying the 256MB sticks in another computer. (At this point,
I would not recommend testing the 1GB DIMM, for fear it is the cause
of all the problems - since you know the 256MB sticks worked just
recently, then testing them might be a bit safer.)

A battery only costs pennies

Try it!
