Computer locks up after using Internet Explorer

[Guest]

My other computer has begun to freeze up everytime I use Internet Explorer.
The error log has the following messages. I have had the computer for a
couple of years, but the problems start a couple of months ago and have
gotten worse. I have downloaded and installed service pack 2. Any help will
be appreciated.

(0x4d0), which lies in the 0x4d0 - 0x4d1 protected address range. This could
lead to system instability. Please contact your system vendor for technical
assistance.

Thanks for your help,

Since you're having problems with both ACPI and your CD-ROM, I'd suggest
updating your motherboard/chipset drivers as the first thing to do. You can
usually find these at the website of the manufacturer of your PC.

Oops - just noticed something else! The dialer.exe may also have something
to do with this. I'd suggest that you scan your system for viruses and
spyware (using updated definitions) to ensure that this isn't a problem
caused by malware.
