Blue screen, even after restoration
Our Toshiba laptop running Windows 7 Home Premium starting giving occasional blue screen errors when it booted, sometimes IRQ_NOT_LESS_OR_EQUAL, sometimes BAD_POOL_CALLER.
I restored an image that I made with Windows Backup about 8 months ago, shortly after purchase. But upon re-boot it gave the IRQ_NOT_LESS_OR_EQUAL right off the bat.
Before the restore I ran Windows Memory Diagnostic, and also ran chkdsk /r from the startup disk command line. Both tests came out clean. Any ideas what to look at next?
Thanks
