Thinkpads Forum

This machine worked for two years running W2K. I was doing the Windows Updates and when it was finished I rebooted it and it BSOD with a ntoskrnl error. I tried rebooting with last-known-good and that worked, but a straight boot would always BSOD. I booted a Win98 floppy with SpinRite on it and ran that. It found no hard drive errors. Sometimes a boot would give a registry error BSOD versus a ntoskrnl BSOD, not consistent. I decided that Windows was corrupted, so I formatted the HDD and reloaded it using the IBM W2K CD that came with the computer, and it still BSOD when I rebooted. I upgraded the BIOS to the latest version from IBM. Still blue screens when reloading Windows. I replaced the CMOS battery. No change. I downloaded and ran PC Doctor from IBM. It reports a system memory error. I removed the 256Mb stick I had installed and reran PC Doctor and it still reports a system memory error.
What has gone wrong with this computer???
TIA for any advice.

I think you really have a 2645-5FU. It's what I have, anyway.

And if the memory test fails with only internal memory installed, then your internal memory has failed.

You can get a used system board from eBay for about $60.

You are right about the model number.
Right now I don't see any motherboards on EBay. I guess I'll just keep trying...

On the subject of replacing the motherboard, I have the hardware manual but still need to ask a dumb question. To do it, do I remove the keyboard and go in from the top, or do I go in from the bottom of the case?

Thanks.

Through the TOP!
