Have you tried restoring it back to its original settings?A registry repair software will run a free scan of your computer and look for errors, especially the ones that cause the blue screens. Once it finds these, and it will, it will fix the errors. The blue screen problem is related with hardware fault it causes blue screens, the most common is because of RAM though. Software can cause them too (ie bad drviers)

driver_irql_not_less_or_equal this error occurs because of a problem in the SCSIPORT driver. The problem occurs when incorrect areas of memory are overwritten or are written to disk. This problem occurs only with SCSIPORT drivers that do not use map buffers for I/O transfers. To determine whether your SCSIPORT driver uses map buffers, contact your Independent Hardware Vendor (IHV) or your Original Equipment Manufacturer (OEM).
