Crashed when opening a picture first time, the screen just pixelated. Managed to get it going after an extended self repair and it crashed again, screen again pixelated but this time I get nothing on screen to at all, the screen stays blank, the PC appears to start but does nothing else?
 
Solution
No that is a small board that controls the power to the screen when this go bad the display can mess up try hold a flash light in a dark room to the screen and see if you can make out any images on the screen (if it is blank). If you can see a image anywhere on the screen (you have to look closely and maybe at an angle), then the issue lies in the inverter look up laptop screen inverter on google to see what it looks like. These are mostly likely housed in the same section of the case as screen not where the motherboard is.

Thanks for that. It is not a laptop as I think you are assuming and is using the onboard graphic card. There is definately no image to be seen, it starts up bleeps and finds the DVD and thats it - nothing else happens.

It lights up, fan goes round, it fids the DVD bleeps but Nno display, not even a blue screen and cannot get a bios screen- just nothing.
It has a high definition Samsung monitor connected through a HDMI cable. It was a picture is lightroom I was trying to open.
My best guess is the graphics card has gone but looking in I see no sign of overheating etc!

Answer these questions

Does the HDD spin up (if you have one)?

"It was a picture is lightroom I was trying to open." What do you mean?

Do you have another computer to try the monitor on to see if it still works?

Is there an onboard peripheral for your monitor to test the computer is working correctly? (You have to take our the GPU or change BIOS settings, in your case remove your GPU)

Have you tried another monitor on problem PC?

What kind of beeps are you getting on the system? (one short beep, one long beep, etc.)

I cannot tell if the HDD spins, the CPU fan does.
Lightroom is a photo program and holds my pictures, trying to open a picture caused the crash.
Tried another monitor with a different lead- nothing
I get one short beep!
Not sure what you mean in para 4?

You connect your monitor to your desktop with a VGA, DVI, DP, Mini DP, HDMI, etc. port, is there a port (slot) as mentioned early to hook up your monitor without using the off board GPU installed. I'm sorry for being terse in my question about lightroom. I was simply asking as you answered in your more recent post. That opening the picture in lightroom caused (or seemed to have caused) the crash.

Basically what were trying to find out is if the machine is POSTing or is it simplly just showing there is power running and no real computation is happening. With the use of onboard gpu and not using the slot enabled gpu (hence graphics "card") you can determine further where the issue lies.

The single short beep would imply that POST (Power-On Self-Test) has passed and the machine is operating but further investigation is necessary.

To tell if the HDD is spinning up you can touch the back end of the HDD while the computer is starting up (may take a few seconds), to feel for vibrations in the drive that indicates it is working. Of coarse you may still feel vibrations of the fan, and this does not help. It is hard to describe but I'm sure you will know the difference.

The CPU fans spinning up just tell you there is power nothing else can be ascertained (except that power is present) by this.

I also insist you try another monitor if it has a HDMI port you can use a tv with HDMI available to test, but again just another item to cross of the list in our forward endeavors to help fix the issue at hand.

Lastly it is always good to copy (ctrl+c) and paste (ctrl+v) the questions someone asks you, and answer then in your reply so we can better follow your answers. (assuming you are computer literate enough to know this)

I hope none of this message comes off as being offensive as this is simply not the reason of any text in this post, but rather to be informative and helpful.

Again I hope the troubleshooting steps that we all provide helps you to resolve your issue. If you are unclear about anything in this post please feel free to pm (private message) me with a URL link to this thread and your question. I will gladly get back to you in a quick and orderly fashion.

Thanks for that.
The PC has not got a seperate graphics card, it is on board and originally had a HDMI connection to monitor, I have since tried a VGA connection to a different monitor - same result, nothing.
I will try your HDD test and get back to you.

Thanks for your help since then I fitted a new motherboard and everything works BUT thought the expensive Samsung monitor might have caused the failure, ie the on board graphics struggled to cope so fitted an Asus Radeon HD6450. I have installed the software and checked through the vga port to an old monitor and it shows its working BUT nothing on the screen (cinected by HDMi).
Any thoughts?
