Hi, I have an old Pavilion ZX5060us notebook that is doing the BSOD now, ever since I created a UBCD4WIN bootable usb flash drive with it. I ran antivirus scan and reinstalled XP, drivers all look ok. Then I ran a diagnostics cd that told me the keyboard controller on the mobo failed. Does this mean I have to replace the whole board? I'm not afraid to work on this thing, I've replaced just about everything else!
