Display won't get any signal

[nikos stebilis]

Hello everyone!I have recently bought a Benq gaming monitor, which was a huge change from my 5:4 old samsung monitor. After buying the new display, I noticed windows desktop was doing really slow on booting, but everything else ran just fine. I googled it, and many people said it is a driver problem, so I downloaded AMD catalyst, let it run, detect my hardware and update the drivers. The problem however, did not go away, and while yesterday my computer was working as expected, today it does not seem to display any signal on the screen. The monitor outputs: "No cable detected". I have tried changing the ram modules, eaving only one of them in, unplugging my DVD, even holding the power button while plugging the power cable. Also, connecting my monitor with vga, dvi, hdmi and connecting it to my motherboards integratsed graphics. Nothing seems to work.. please help.
Specs: AMD FX-4350
Radeon HD 7770
Mobo: Gigabyte GA-78LMT-S2P

Hi, Try connecting a case speaker to the motherboard, start it with no RAMs installed and see if any beeps.

I do not have a case speaker right now... Isn't there any other way to check for the problem?

If still no go, with a case speaker you'd know if motherboard and CPU do work.

I have done all of the aboove with no luck. The CPU area does get pretty hot (but not like overheating), So, it should be my motherboard?

Hard to say.
