There are several normal reasons for your problem. Since you added the
device to the system, the power supply for the system could now be under
powered. Disconnect the new device and try powering up the system.
Overheating could be a cause - check the power supply fan and, if installed,
the CPU and video card fans. Check that the RAM is properly seated.

After that the diagnostics become more difficult and start with reducing the
system to its minimum components and then adding to it after each attempt at
booting. The beep tones on booting are an indication of any problems. If
there are no beep tones with the minimum components, your motherboard could
be the problem.

I hope you find the answer without too much effort or cost.

Subject: [PCBUILD] System On System Off


I was switching out a CD-RW drive from one machine to another last
night.  The machine I installed it on is a Windows 2000 Server, P3, 900
Mhz, 256 mb ram.   I ONLY disconnected the CD ROM cables and power cable
to it.

When I put it back together, and powered on, the computer turned on for
about 2 seconds and then turned off.  I checked all the cables, took out
the memory chips, tried it again, and same thing.

Do I start with the power supply as the culprit or go right to the
motherboard and consider replacing it?

Thanks
