Aye have chimed in at your other thread
What actually happens when you try and power up the computer.

Absolutely nothing lol and there isn’t even the led on the motherboard lit up hence why I assume that the PSU is at least the start of the issue lolComment

The following is perfectly safe if you follow the steps accordingly;
Disconnect the power cord from the wall socket.
Press the case power on button.
Disconnect all of the PSU connections to the MB, any HDDs and optical drives etc, put the 24 pin ATX power connection to one side then secure the others away from the inside of the case, straighten out a paperclip then bend it into a U shape, place the two ends of the paperclip into pins 15 and 16 as shown in my attachment, connect and then turn on the power to the PSU, let us know if the PSU fan activates.
An example video hereComment

Sorry for the delay on this…
Have done the test and the fan starts up so unfortunately I imagine that this means it’s more likely to be something on the motherboardComment

Could be the case switch, to check this see my canned info and the attachment below;
Reconnect the PSU to only the 24-pin EATX power connector and the 8-pin ATX 12V power connector on the MB.
Disconnect the chassis power on connection from the header on the MB.
As your MB doesn`t have a power test switch you will need to short out the 2 power on pins on the MB header to get the PSU to activate, you can use a small flat bladed screwdriver or a paper clip bent into a U shape, this is perfectly safe if you do not touch anything else.
If the PSU does not activate using this method then the MB may well be bad.Comment

Okay not sure about this news lol the fan doesn’t turn however the light on the MB does turn on when connected

the fan doesn’t turn
Which fan doesn’t turn on?
I just replaced a power supply earlier this week. I had a light on the motherboard but otherwise the computer appeared dead.Comment

The PSU can didn’t turn in the second but did on the first… I’m new to this so not certain on what to draw from those though lolComment

If the above happened after following the steps suggested in my reply #35 two possible causes come to mind, the MB is not sending the “power good signal” to the PSU or the PSU is bad, swapping in a known good PSU for testing and having the present PSU professionally tested are the only two safe suggestions I can make to be honest.Originally posted by Markh510Okay not sure about this news lol the fan doesn’t turn however the light on the MB does turn on when connected
Some info for you, as a PSU puts out various voltages +3.3V, +5V and +12V it may appear that the PSU is working correctly but it is not, any significant drop of any output can prevent the system from booting up, the other scenario is a significant increase in the output which can be worse as it can fry one or more major components such as the MB, CPU, RAM and add on video card etc.Comment

Yeah I only have one PSU that is known to be workig but I don’t think the owner will be happy for me to take it regardless of my assurances haha
As for testing it seems a lot of effort to go through for something I will want to replace soon anyway so I think I may just cut my losses and look at just buying new… I have a few components and the RAM I can transfer so will help at least a little lolComment

K, will head over to your other thread when I get back from work later on today, being that you will also be purchasing a new PSU as part of the upgrade you can always come back and test this MB with it first.Comment

Any updates for us?Comment
-
Sorry for the delay I didn’t see the last comment and was caught up in the other thread. Here is the update from the other thread:
Just an update for you guys that have helped me soo much over this while ordeal… I got the PSU today and connected everything up and now the pc will power up which is an improvement lol
Taking the video card out seems to have solved the display problem and so now I imagine that it is just the video card that will need replacing to restore multiple displaysComment
-
No worries, we like to check back when a thread goes quiet in case folk have missed a reply etc.
If you have video from the MBs graphic chip with the add on card removed but no video from the add on card when only connected to that it does suggest that the add on video card has failed.
Edit to add: Did you ever try the add on video card in the second PCI-E slot.Comment
-
Yeah it seems to be that even when I don’t connect to the video card if it is attached to the mb then there is no video.
I must admitt I haven’t tried the other slot. Will try a bit later todayComment
