turns on but screen doesn't start

[Deleted]

I just installed windows 10 on my laptop, everything was fine. I shutted off the pc and then turned it on, but nothing happened. It was only a black screen. Power lights turned on as usual but nothing happened with the other ones: wifi, hard drive. After doing it several times os charged but just like after a minute with the black screen and trying a lot.

I tried to turned on and off again several times but the result was the same. I even tried reinstalling windows, but this time i used windows 8, but the problem stayed the same. I kept doing the turnin off and on thing but then three short beeps started. I took it to some friend of mine and he restarted the bios but the first problem stayed the same.

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
