No signal to monitor

[ojgbrown]

Hopefully you guys can assist.

PC had been playing up, BSOD etc and froze on the blue screen meaning no choice but to turn off and on again. Upon turning the PC on again I get no visual on the monitor, just an orange light (as opposed to blue) and it gives me the message saying there is no signal to the monitor.

I have thus far taken the following steps with no success:

- Checked that the cable connections at both ends are secure

- Ran the signal cable to both the mobo and GPU (same issue with both)

- Tested hooking it up to my tv to see if it was the monitor was knackered but had the same issue.

- Removed the GPU, two HDD's, CD drive and retested. Same issue.

- Removed the memory (4x4gb sticks totalling 16gb), checked for dirt, replaced.

- unplugged power, then held power button or a minute before plugging in again and trying again (some people said they had some success with this)

- removed CMOS battery from mobo, put back in and tried again. No improvement.


I built the machine and it has ran fine for a couple of years. I am far from an expert however and am not sure what the issue is here. I suspect that the motherboard is knackered in some way, but it seems odd as the pc comes on, the GPU and CPU fans come on etc all as normal- just no signal.

I have a new motherboard arriving today should that be my only recourse but I would rather find a fix and send it back!



Specs:

Asrock Z68 Pro 3
i5-2500k @ STOCK (never overclocked)
Radeon 7950 windforce 3gb
16gb RAM
Samsung spinpoint 1tb HDD


The mobo I have coming is an Asrock z75 pro3.



If anybody can assist it would be hugely appreciated.


Kind regards,
Oliver

Congratulations! Your graphics card has just blown itself up

(Sorry, couldn't resist the light-heartedness)

Your Z68 Pro appears to have onboard graphics. Connect that up, and see if it runs - which will tell you if its the graphics card (most likely) or also possible, the motherboard, which has died.

thankyou for your reply, however please note that I have already stated that I have tried connecting both the GPU and mobo separately and had no joy, thus leading me to believe that the mobo is dead. Plugging the cable into the motherboard (as opposed to the 7950 where it was originally) was literally the first thing I tried.

Ah sorry, I'd mis-understood that section.

Probably a blown motherboard then, but just incase try putting just 1 stick of RAM in and see if you get anything working, and then move it to each slot 1 at a time, and see if it boots with just 1 stick of RAM in.
