The computer has rebooted from a bugcheck. The bugcheck was D1.

Last night, I got a blue screen. Copy/pasted from the event viewer.

The computer has rebooted from a bugcheck.
The bugcheck was: 0x100000d1 (0x00000002, 0x00000002, 0x00000001, 0x856807fc).
A dump was saved in: C:\WINDOWS\Minidump\Mini022607-01.dmp.

That should be attached

However, as I went to sleep, leaving the computer on, I got a popup saying that Windows has recovered from a serious system error or something similar. In the event viewer, I got:

Error code 100000d1, parameter1 00000002, parameter2 00000002, parameter3 00000001, parameter4 856807fc.

Could anyone help me with tis?

In case anyone is wondering, the computer is running XP Professional.

I have uninstalled a webcam (Labtec Webcam Pro), which I believe might have been the source of the problem. I have also uninstalled Miranda IM just in case.

While it has not be a consistant problem, that pop-up worries me quite a bit. I'm just hoping that the mini-dump would lead to what I would need to exactly get rid of.

There's no useful info in that dump (by itself). If it continues to crash then post the new minidump files. Wait until you get 3 or 4.

Faulty ram

According to your minidump, it crashes at portcls.sys and it is symptom of faulty memory. However one minidump is insufficient to confirm the culprit. Attach more minidumps here. Run memtest to stress test your ram and Refer this document
