Hey guys. I have this computer that my uncle gave to me. i first booted it up, but the screen wont come on. I've checked the monitor and video card on my other working computer, and they work just fine. My screen can tell its connected to the computer, and I've checked all the wires. My computer's power button is flashing orange. I cant seem to find out why the screen wont come on. Anything i could do? I asked my uncle where he had gotten the computer, and he said he got it from his neighbor who said it had a virus on it. My uncle replaced the hard drive, and gave the computer to me. I'm not sure if he had booted it up before he got the hard drive. I thought that maybe the hard drive was faulty, so i checked it. when the computer was on, it wasn't wirring or anything. so i replaced it with a different one that i was sure worked. The new one wirred, but the screen still didn't turn on. I really hope you guys could help.
