No signal to Monitor. How to fix this problem?

December 29, 2015 at 16:57:43
Specs: Windows 7 Professional
When i played a game which doesn't use too much graphics yesterday when i woke up and turned my desktop on it wouldn't work. I played the game for 4 hours already and i checked my desktop CPU if it was hot. The temperature is at least 60 degrees and above. Then the next day it wouldn't work. I started turning my desktop on and off and the CPU worked! But the problem is nothing displays on my monitor and it keeps going to sleep mode every time i turn my desktop on and off. I changed it's position and set it up on a table so that the CPU and it's components wouldn't have any contact with metal that may have static electricity or what so ever. So far i've been trying to fix it by changing it's graphics card and some cards such as accelerator and card feeds but still wouldn't work. My desktop has (2) two ports for my monitor but i plugged it in, in the one that has the graphics but i din't try the main port for the monitor yet.

"and the CPU worked"
Do you mean that, or did you mean the "computer" worked?

You can forget those ideas about static - not a problem.

No signal on the screen simply means what it says, nothing is coming out of the computer.

Have you cleaned the vents, fans and CPU heat sink lately?
The high temperatures might have zapped something - the CPU itself if there are seating issues with it's heat sink.

Let us have some actual temperature measurements if you get it started

Try the monitor on both ports.

Always pop back and let us know the outcome - thanks

Well just CPU worked good and there is a boot load start-up sound. But the monitor din't pop up.

I tried the monitor on both ports i even bought a new cable for the monitor.

Nothing seems to work but i got a graphics card that has a monitor port in it. Haven't tried it yet but i'm trying it tomorrow maybe.

Also tried to plug in other monitors and nothing seems to work.

How can i find out if both ports are broken or damaged?

Just before we go off at a tangent, CPU means "Central Processor Unit", see here:
Not to be confused with "computer" which is the whole thing including the CPU chip.

A CPU makes no noise so what you are hearing is probably fans or maybe the hard disk searching. The heat sink (cooler) I mentioned earlier is on top of the CPU, under the fan, and takes its heat away. Do not remove it for cleaning otherwise the thermal seal will have to be remade.

As I said before "no signal" means just that and virtually confirms the monitor itself is OK.

What the original poster means by "CPU" here is obviously the
box which includes the motherboard, CPU, RAM sticks, power
supply, fans, hard drives, optical drives, and any I/O boards
plugged into the motherboard. It excludes peripherals such
as monitor, keyboard, and mouse.

The question is what signs the OP observes and can report
clearly enough for others here to interpret accurately.

Re #4

I'm not entirely in agreement. I've seen posts on this forum that have collected stacks of irrelevant responses where the wrong terminology had been used, virtually restarting the post when it was realised. Always worth straightening it out in my opinion - good for the poster in future too. Teach a man to fish etc.

I had second doubts on this one was when #2 came in, despite my meagre attempts to clarify it without undue elaboration in the first response.

Assuming the motherboard has a VGA connector, If you take out the Graphics card and connect the monitor to the VGA connector on the motherboard, still nothing?

Tried new VGA connector by the way still wouldn't work - My unit shows no responses at all. No beeps, no screen error, nothing. My monitor just keeps restarting but the unit itself isn't - What should I do?

I reconnected the VGA properly and make sure it's screwed properly as well. Removed USB mouse, keyboards, etc. to make sure that it's not grounded but still the monitor shows no response - The screen restarts it's either off or shows a black screen with very little brightness.

Have you checked the monitor on another computer or another one on the problem computer to be absolutely sure the monitor itself is OK?
Sorry if I've missed it in the above posts but I am just rushing past quickly.
