Please help!!!! Bluescreen errors have started. First the bluescreen reported system32.dll is missing. I reformated and reinstalled; however, while in the "installing windows" part of the setup procedure bluescreen errors stop the installation. The following is an example of the XP TROUBLE CODE: IRQL_NOT_LESS_OR_EQUAL 0*0000000a (0*c0006580, 0*00000002, 0*00000000, 0*80501e85) I have replaced the video card from nivda 64 to a 128. I have replaced the RAM. The trial and error way of repair is too costly to continue. Please someone help me.
