faultrep.dll causing error on boot up

Running Win XP Pro
CPU: AMD Athlon XP, 2400+
384MB of RAM
(Tell me if you need more info, I have no idea what's important)

Lately when I restart or turn on the computer I get a Windows recovered from a serious error message. I look up the details, which lists two files, a minidump file and a sysdata.xml file. Then checked the event viewer for system errors which showed a description of: Error code 00000050, parameter1 de4e72e0, parameter2 00000000, parameter3 804edb3d, parameter4 00000000. When I click on the link under for more info, it says that faultrep.dll is the file with the error. Don't know if this is related, but I've also been having problems with my DVD RW drive. It just stalls and refuses to even open up when I try burning anything. But that's more for the hardware forum...
