I thought I'd stop in for a few minutes and say, "hi everyone." I've been working on my wife's laptop, and after awhile I just want to scream, and go watch tv for awhile. I put a new hard drive into to, and have nothing but problems, non-stop. Finally I switched in the bios from AHCI to Compatibility Controller mode, and everything but the sound works. The sound driver keeps saying unsigned. I tried reinstalling the driver, but still the same problem. If I press F8 while booting and select boot with unassigned drivers, everything works great. I uninstalled the sound driver again, and will try reinstalling it. Otherwise I guess it's always going to be an F8 unassigned signed drivers boot from not on... ugh..!
