No display on own build PC

[Mickyd]

I am building a pc (obviously) i am using a motherboard that my nephew used top use its only about a year old i have bought new everthing apart from the case motherboard and CPU, i have assembled everything but when i power it up the little LED lights up the fans spin but iut would seem thats about all else it will do there is nothing displaying on the monitor at all - I am hoping its not the mobo thats broken - so erm any suggestions THANKS

Doublecheck all your wiring connections. Usually, there are two power cables that need connected to the motherboard, the 24 pin power and also either a 4 pin or 8 pin for CPU.

Many motherboards have lights and/or a two character display for the BIOS. If yours has this check for any error codes.

I have done all that - I pulled em out and back in - made sure they are all secure just the same as before no signal on the monitor I have treied HDMI and DVi but neither works

Do you have any diagnostic/BIOS status indicators on your motherboard?
With the light and fan running it says its powering on.

What is the motherboard model? If you are using a separate video card, reseat the card with the PC powered off (unplug then plug back in).

There doesnt seem to be any status indicators on the board the mother is ASUS A88XM-A

Are you using the internal video or a separate video card?

Also, a BIOS (CMOS) reset may be needed since this was used and may have some custom settings. I see a jumper on the motherboard for this.

The manual shows the jumper and how to clear/reset.

Its the motherboards video card its using. I will have a look at the reset thingie after me tea

 

[Mickyd]

I have treied doing that and theres still no signal to the monitor

 

[fireberd]

I would suspect its down to 3 possibilities.
1. The ATX 12V connection or no 12V from the power supply
2. CPU
3. Motherboard

I shoulda known not to try n use that mobo, thats how my luck runs. Oh well. Thanks for your help

 

[fireberd]

Sadly, you would never know which is the problem without a swap (e.g. another known good CPU).

 

[Mickyd]

Yeah thats true, i think i will just get another mobo bundle

 

[Mickyd]

I got another mobo - it worked i had screen - BUT would youbelieve the HD was DOA - so after a new hard drive put in - the PC is now bursting with life
