(the internet had been working fine before that) and he manually turned it off...
upon trying to reboot it won't reboot, the lenovo screen comes up and I can get into the bios utility but if it tries to boot windows it goes to the black screen with the flashing cursor then after about 15 seconds or so there appears blotchy patches of color in various places of the screen and nothing else happens...
any ideas as to what caused this and how can I fix it? It is our main computer on the network so I REALLY need to get it back operational obviously....
