Hi everyone...I really need your help!
Here is the problem:
While I was surfing on the internet my computer crashed and restarted itself with a No Signal message on the screen. I tried restarting it a few times but didn’t work.
So I decided to open it, remove my VGA (GTX 1070) and connect a DVI cable to the integrated graphic card...computer turned on but “No Signal”.
Checked all the RAMs by removing them one by one. One RAM didn’t work so I tested the computer with the other two. It worked perfectly. So I reinstalled the VGA and tested again...it worked. I tried to install the “defective” RAM in another slot and guess what...it worked.
After like 30 minutes computer crashed again with a no signal status on the screen. Removed the “defective” RAM but still no signal status.
I have no idea what’s going on with it.
P.S.:sorry for my English but it’s not my native language.

I don’t know if this can help but keyboard doesn’t work while mouse does (tried connecting them in the same USB port). This is so strange...
