PC turns on but wont boot

[Alex15787]

No beeps or display was shown across all 16 tests Im afraid

No beeps means that your RAM and the memory slots are ok and that the problem is after both of those have been tested as part of the power on self test (POST) the video solution is the next item that gets checked so the problem is with one or more of the following.

The CPU.
The motherboard.
The video cable that is being used, this includes it being damaged or not connected properly.

What I suggest you do is remove the CMOS battery from the MB and leave it out overnight then put it back and then see if your get any video from the HDMI port on the MB, the behaviour that you describe could be caused by the onboard graphics having been disabled in the BIOS somehow, leaving the CMOS battery out overnight would clear such a setting, if this does not work you are going to have to take the PC to a local tech I`m afraid.

Tried it with a different video cable to no avail, Ill leave the battery out tonight and give that a go tomorrow, but the issue is definitely not with the video cable

[phillpower2]

The video cable was effectively ruled out in my reply #56 but as we are not there we cannot rule anything out 100%.

Just so that you are aware, the “No Signal” message tells us that the screen is 100% ok, the video cable almost certainly is an that the problem is with the source of the video which in this instance is the CPUs HD Graphics 4600, if this is bad you need a new CPU.

When you did the RAM tests - Had you selected the PC on the TVs Source button.

NB: Before removing the CMOS battery, disconnect the power cord from the wall socket and press the case power button for twenty seconds to get rid of any residual charge in the system.

Sorry for the late reply, but to answer your most recent reply, I tried it on a few tests but not all of them, still got no signal, and I was not able to removr the cmos last night as I tried prying it and wouldnt budge and I was scared of potentially damaging it

[phillpower2]

No worries about the delay in replying, we understand that you have other things to take care of.

The battery should come out easy and certainly not need any prying, looking at your MB the battery holder looks to be the type in the middle in the attachment in my reply #62, check and confirm this for us and we will let you know how to remove the battery.

If you cannot safely remove the battery we have no other option than to advise you to take the PC to a local tech or tech store, if this is the case, steer clear of the likes of PC World who are next to useless but charge a fortune.

[Alex15787]

It looks most similar to the second one, and I appreciate all the help you’ve given Im going to start looking into some local repair shops

[phillpower2]

Thought it would be, as you look at the picture that was uploaded, note the silver tab on the right hand side of the battery holder, that is spring loaded and if you press something not conductive like a Q tip against the metal tab to push it inwards the battery should pop up for you, see video here which shows the battery being removed on a Dell PC.

No problem (y)
