I've been asked to look at a computer that won't start anymore. It's an..older...HP RP5000, serving as a cash register for a small club, so if they need it, they really need it.
It's been in storage the past 7 months and worked fine prior to that. I gave it a new BIOS battery because it had forgotten it's settings, but it's still not booting.
It's doing the old blinking cursor after BIOS splash-screen thing. I figured it's the usual, but it isn't. The usual methods (that I know of) haven't led to success.
I tried the Windows Repair from the XP CD, did checkdisk, fixmbr, fixboot, /rebuildfg, the whole nine yards, they all ran successfully, but didn't help.
I even tried letting Testdisk fix the MBR...nothing.
I also tried cloning to a different drive, again nothing. Hell, I even tried the drive in another, identical RP5000 just to make sure the IDE controller isn't bricked (altho it's booting from CD, so I didn't really think that was it)...just does the same thing.
Here's the funny thing, however: If i plug the drive into a USB-IDE adaptor and let the PC boot from USB, XP starts booting, I see the loading screen. Then it obviously reboots because it can't handle the suddenly different storage controller.
Reinstalling, sadly, is only a last-ditch measure, because it would require to get in touch with the coder of the cash register software to reinstall and restore that to working order, which would cost a pretty penny. So I'm trying to exhaust other options first. Sadly, I'm out of ideas.
Anybody got any tips?
