Well, it wouldn't and here's the scenario:

I've been running it for over two years without any problem, but when I went to boot it, it stopped asking me to "insert a boot disk and press any key to continue", or something similar. If you set your system in BIOS to boot off of the CD ROM only, and insert an non-bootable CD - it's that error.

The system has two IDE DVD ROMs, and two HDs - one as Primary on IDE but mainly used as an "in case" backup drive, and the other as Primary on SATA.

I changed the boot sequence in CMOS to HD only, thinking that somehow it may have gotten "confused", but that didn't make any difference. Then I opened the case, and disconnected the power cable on the IDE HD drive in order to insure that the only bootable drive that CMOS would find is the main SATA drive.

This time the system booted successfully to XP SP2 Home. It seemed a little slow, but that may be my imagination since I've been using a faster laptop recently. I did have a problem with CA's Internet Security Suite 2007 slowing down the system, and tried to uninstall it (all but the firewall would uninstall) and then re-install it off of the CD. At the point where it would begin installing, the system immediately shutdown, and re-booted. Thinking that I may have a power supply problem since by disconnecting the IDE HD it would now boot, I shut down and disconnected one of the DVD/CD drives. Same problem at exactly the same spot in the re-install of CA's program. Shut down again, and reconnected that DVD drive, and disconnected the other - no help, it again shut down and re-booted at the exact same spot. I believe that in the installation routine, this would be the time when the DVD drive would be reading data and it would be writing at the same time to the HD, so I'm still suspicious of the power supply.

As long as I'm not using the DVD drives, and only have the one SATA drive running, the system seems fine. I've run AVG's anti-virus and anti-rootkit programs, spybot and Adaware, MS Defender, and, before I uninstalled it, the CA AV/AS suite. Nothing was found except for a few cookies. I feel reasonably confident that the problem is hardware related.

So, my question: is there a program, besides ASUS's PCprobe, that I could be running that would monitor the PS? PCprobe is showing what appears to be consistent voltages, and when the system shut down it happened so fast that I don't see anything in the "history" showing a problem. Should I be monitoring the system board with some other product in case my problem is systemboard related?

Or, is this clearly a PS problem?

The good news - I've been able to backup everything today, so even if the HD fails, I'm OK regarding the data.

Hmmm...

in the last 10 minutes, PCProbe has shown two spikes in the 5 V.

Make that 3.

I think I'm buying a new PS tomorrow.

I'm guessing no one is posting in this thread because they agree with my assessment and don't have anything to add?

Make that, "I'm hoping...".

Wow, the folks on this board are great!

Put in a new power supply, and it booted right up with no problem!

Couldn't have done it without you1

:thumbsup:

Glad we could help. :thumbsup:

And yes, the PSU was the obvious suspect.

Yeah, I thought so too.

Just felt like posting the problem so some people could see how weird a PC might be acting, and it's not the HD or the OS or the video card, etc. even though some symptoms might imply that it is.

Power supply problems can cause some really strange problems sometimes.




Seriously, this board is a great resource, and I was just being facetious.
