I have a Dell Dimension 3000 with 512mb of Ram. I installed a single stick of ram because I thought one of the sockets was bad. It ran fine, but slow after that, so I thought I would try changing back to the old ram. Well now I get the Blue screen and an error message, Bad Pool Caller. I have tried everything to repair this, but nothing has worked so far. I can't boot up the computer in any mode. It gets as far as saying starting windows, then the Blue screen comes up with the bad pool caller message and locks up.

Can anyone help me to get my computer up and running again.

The following worked for me.

I encounted this error during a re-install of WinXP Home edition. I read several posts online and came to the conclusion that it was probably a device/driver issue.

I disabled all of the onboard devices (USB, Sound, LAN, PCI slots) via the BIOS. Installation worked fine, windows booted as normal.

I then went back into the BIOS and re-enabled everything. Windows re-detected everything and all is fine now.

Hope this helps
