I had a "friend" download a bunch of crap onto my computer. I went through and started deleting temp files, etc. I fear I ventured into somewhere I should not have been, as I wiped off a lot more than temp files and cookies. The computer shut down and now when it starts, gives me the Dell start up screen. It then gives me a black window that says it missing a file, press F# (I cant remember the exact button off the top of my head) to retry. I press it and it keeps cycling through this. Have I permanently damaged my laptop? It is as simple as putting in the recovery CD? Unfortunetely I dont have that and not sure why it got tossed. Someone told me it may be hardware failure but would it start to boot up if it was? Any help would be greatly appreciated.
