I was playing the walking dead the other day when my screen froze and a buzzing noise was coming from my headphones i couldn't do anything i tried to alt+4,alt+tap nothing worked so i decided to restart the computer and since then its just turn on gives no signal message and stay on and sometimes its turn off after awhile, i suspected it could be a faulty vga port but i don't have a DVI cable nor do i have a hmdi port so im kinda lost here
Specs:
Intel core i3 2120
8gb ram
H61M-K
No external graphics card

Note:when i said it turns off after i meant it restart again
