I know enough about computers to follow advanced instructions, but ive never dealt with WHATEVER my friend did to my computer, and I dont really care, but I need to reformat it, and save (read: backup) the hard drive. heres exactly whats up (simplified) , and I need a explanation of how to. -Computer can turn on, but it wont do anything - you cannot hold F12 or delete or anything, because not even the first text appears - I cannot get a disk, USB, or anything else to boot from, because it cannot get that far in loading what a basic computer is, to even do that - it can not respond to any kind of keyboard or mouse input and stays completly black (altho a diffrent shade of black from either a off moniter or a powered moniter with a off computer, so I know the moniter is getting SOMETHING, just nothing that does anything -it is not a faulty video cord, it works fine on other computers I own, and trying other monitors + cords doesn't work either. -I have plenty enough space to do it the wrong way and install another OS while one is already installed and boot from that to backup the hard drive, but the computer clearly cant even show anything, let alone receive disk information (or mouse or keyboard input to hit next anyway) so that option is null -It is not overheated, or underheated, nor is it fan ishues, or anything else stupid, its clearly however more then a virus (not to say a virus is also not present, but unless some uber tier virus hit the net recently, a virus is not the cause...nor does it matter) -I want to either, preferably without taking it apart, access the harddrive from another computer, I have pretty much any cord it would require, or to put it diffrently, I have never needed a cord I did not own in the last year -I asume sence it stays powered on (altho it doesn't do anything past that) that the harddrive and disk drive the computer has are readable, it just cant do anything about because it cant load anything to do anything, so I asume theres some method to plug the computer itself into another computer and access the hard drive as a external, or something to access it from another computer short of taking apart my computer with a screwdriver, how do I access the hard drive externally? (and no I do not want someone to reply take it to a future shop or something) thanks in advance, I have never had a computer that couldn't emit video, or rather, cant even get to the process to emit video, and honestly have no idea how to fix it, il just reformat.
