No display on Computer

Densityy · 27 Apr 2010 at 20:03

So, first of all sorry if this has been posted before.

Ok so i turn my computer on, i can feel and see the fans going on both my CPU fan and my GFX card fan i can hear the CD drive and the harddrive working but i have no display. I have tried swapping the monitors etc.. But still no use, so i'm guessing something has broken. Just need one of you fellas to tell me what it is

Willing to try things out if it will help find whats wrong.

Thanks in advance - Jake.

- I also don't hear that beep you usaully hear when you turn a computer on if that helps.

I'd double check to make sure you've not forgotten to plug in the additional 6 pin GFX and 8pin CPU power cables.

Have you made any recent changes to the system? Or moved it around?

Try a CMOS reset and start with only one memory module installed.

Can you post your system details, including psu

ACER
Processor:
Intel(R) Core(TM)2 Duo CPU E4700 @ 2.60GHz (2 CPUs), ~2.6GHz

I want to try find out the problem so i can start to think about buying a new part for it.

might sound silly but have you tried using the on-board gfx ?

Densityy · 28 Apr 2010 at 17:16

Yeah that was the first thing i tried still nothing :/

Densityy · 28 Apr 2010 at 23:08

Anyone have anymore ideas what it could be?

Bump...

I think the first thing you need to do is check that the power supply is supplying good stable voltages.. You can use my guide here to help.

Now that you have eliminated the Graphics card, PSu and monitor, it has to be either the Motherboard or CPU. The fact you get no POST beep suggests the mobo and that's where my money is on if it isn't the PSU.

This happened to me once about a year back and someone said to switch everything off then make sure monitor is turned on as normal, reboot the tower unit and wait until you feel everything has loaded then still leaving monitor on pull out the power plug from socket for monitor only, wait a few seconds and replug back in. I don't know why but it worked and has never given me a problem since. Worth a try anyway. Good luck.

Yeah, i think if i did it all right my PSU should be fine. Looking like its a new MOBO.
