Hey OcUK,

I just put together my Dads PC, I put in a new mobo, new CPU, new graphics card, new PSU and new HDD. Left HDD, two PCI things and two DVD drives in.

Now, I come to turn the PC on and fans spin, DVD drives whir but I get no POST and no display on my monitor, USB mouse wont work, PS/U Keyboard wont work, nothing.

What is the problem here?
 
I've got a 1GB and 2GB sticks, tried just one stick in, no luck.

And the GPU is brand new, I could test in my PC but that means I'd have to shut everything I'm doing....

Tried a CMOS clear

Thats the point mate its new and could be doa straight out of the box!

I'd try it to be honest, process of elimination is the aim of the game :D

Ok, it works, just tried on my PC.

I'm thinking mobo is dead, no connections coming from it works, no PCI connections work, well, the fan spins on my GPU, just the CPU Fan spins, only thing I see of life from the mobo.
 
Disconnect everything apart from the GFX card, and make sure the GFX card is seated properly (worth taking it out and reseating it, they often need a fair bit of pressure to seat properly). Make sure GFX has all required power connectors (it may need two depending on model). Make sure mobo has all required power connectors (again may need both 24 pin and 8 pin depending on model).

So, with only CPU, 1 stick of known good memory and the GFX, try booting. If that works, add components back in 1 by 1. If it doesn't, try with another GFX card if available or a different stick of memory and finally a different PSU if available.

It's all about a process of elimination and working through methodically. Good luck :)

Ok, tried that, it doesn't work. I'm thinking the motherboard is broken, as no USB ports work on it.
 
is the CPU fully supported by the current bios on that board? I had the same issue with my phenom.
 
Yeah that sucks :(

Just wondering how you know that USB doesn't work though? If it doesn't post, USB won't have initialised, so possibly solving the POST issue will get your ports working.

To be fair it's probably irrelevant - sounds like the board is pretty dead. Last thing to try is another (compatible of course if you have one) CPU, maybe an older version just in case the supplied bios can't cope with the latest revision, but that's clutching at straws really...

offtopic: woohoo 100 posts and free shipping! that's only taken me 5 years lol

That maybe the case but check that the bios it has been shipped with supports that particular CPU. I had to do a bios update on mine. I had the same symptoms.

Well, Quad Core works with it, so why wont Dual Core?

Well, mouse doesn't turn on, and it wont POST, ever...

What avrc meant was that although the board supports your chip the BIOS that it was shipped with may not have. If it had posted, and this proved to be the case, you would have had to flash the BIOS to the latest version that did recognise your cpu. However, this is all academic as your motherboard wont even post...

Hope you have better luck with the next one.

why hasnt anyone suggested this?

maybe its the board shorting because when i changed my pc case i wasnt getting any displays but fans were spinning etc and i knew it worked because of the fact it worked in my old case, i took pc apart and built out of case and it worked.

why dont you try this?
 
Agreed, rowannew is right - it's deff worth eliminating this as a possible cause. (Good spot - i, mistakenly, thought this had already been suggested.)

It will seem like a lot of effort but it's the best and surest way to rule out this type of fault.
