My sons Asus Z87-a motherboard came on with a redcpu light, took it to my local shop and they said the CPU must be gone, so i brought a new CPU from the forums put it in and the light is still red and will not even give a output to the screen...
Have you checked that each ram stick is working and if so, try in different A1 in B2 or something.
If it is hanging on code like @Ftorek mentions, google it.
I have also come across when the CPU was not reseated properly too esp on the AMD when they one of the pins was broken. Check the mobo cpu seat with a bright light to see if pins are ok but I would do the ram first.
Well... it will be tricky to pinpoint the issue then - normally i'd re-seat everything - check for pins on cpu etc. check all connectors (power to mb, cpu etc...), try booting up with different memory sticks in different slots etc. - and it that doesn't yield any results - you'd need to test components separately - that's tricky if you don't have a bit of bunch spares lying around...
happened to me when building pcs before that on the first start it wouldn't boot - and usually it's a build mistake - all parts are good but not enough power to mb or something....
thanks for all the advice, reading the manual, there are led's for ram, cpu etc.. So Ram is all good, but the red cpu light is always on, i am thinking he may have played with the cpu and perhaps does something to the pins on the motherboard, so a new board may be needed? So if i need source a second hand one do i go for the same make and model?
Hi Forever - this MSI actually wont work - it's different socket
I'd buy exact replacement if u can find it.
If no - it needs to be LGA1150 socket and i'd look for Z87 chipset
Look here - that's the spec for your one: Z87-A | Motherboards | ASUS USA
Important things to look at are socket, chipset and memory....
