When I start my computer, if the Plug and Play Service is turned on, I get an error. "The instruction at 0x00aa96bc referenced memory at 0x00000000. The memory could not be written." This error goes away if I turn off the plug and play service, however my device manager does not load, my computer thinks it's on battery when it's not and my network connections are not present. These are the only ones that I have found. Can I reinstall the plug and play service somehow, or is there any other sollution. On another note I ran Memtest 86 on this machine for 5 days without one error, so I don't think it's the Ram Chip. I also don't have any periphial devices pluged in to the machine at this time.
This error also seems to be causeing another Generic Host Process for Win32 Services to experience problems. The service is one of the SVChost.exe services, so I don't know which program is using the svchost service. The service name is svchost.exe.mdmp. The service closes when windows starts, I don't know what the effects of this is.
This is a widows xp professional system.
