Hi, have you any idea what these error messages mean please? Error#: -935 Error#: 94001 Null Input Paramater Unexpected D4 Field. I dont even know if its a hardware/software problem, but i am afraid it may effect the security of my home pcAll i know is 2 weeks ago and engineer did a full system restore because i had locked myself out of my pc. All seemed well, except i cannot turn my pc on/off/restart this seems to be blocked by something (i have to unplug it). it keeps going into hibination mode even tho i uncheck that box. i am just worried something is wrong. thanks so much if u can help. suz
