Computer crashes when I run a fast scan of Superantispyware

When I run a full scan using Malwarebytes the computer also crashes but not it doesn't crash on a fast scan. I can run a fast scan or a full scan using Spyware Terminator without a problem. I do not seem to be infected with any spyware. When I get the blue screen of death here is the error message

On Sun 4/18/2010 5:53:59 PM your computer crashed
This was likely caused by the following module: xgiesc.sys
Bugcheck code: 0x1000008E (0xC0000005, 0xED77387E, 0xB139CB0C, 0x0)
Error: KERNEL_MODE_EXCEPTION_NOT_HANDLED_M
file path: C:\WINDOWS\system32\xgiesc.sys

I am just an intermediate level user so please keep it simple for me. Is there a fix for me. i don't understand the message. I do not know how to find the module xgiesc.sys and I do not understand the error relating to the Kernel mode. I have an old computer running XP home :cry
