ok the day before yesterday my comp was fine, worked perfect. before it shut down it automatically updated then turned off, when i go to turn it on in the moring i get a black screen of death. the drives are runing, the cooling fan turns on, the cpu fan turns on , but it does not boot. i tried taking the battery out to reset the cmos memory, i removed the ram, i dont think its the psu(power supply) im stumped and im preying something like the hdd didnt failed, any help or toubleshooting would be much appreciated
