[SOLVED] Asus P8P67LE won't post

[ChillyPenguin]

Yes, it's another "wont post" thread 🙁.

And yes, I've read the sticky, and have been through all the steps, short of pulling out the mobo and breadboarding it.

On my ageing Asus P8P67LE mobo, I was trying to upgrade my Nvidia 660 GTS with an AMD RX 570. I had it working fine, but then tried moving it from one PCIE slot to the other one because I thought it might get more performance there. I've had no good posts ever since doing that.

I've stripped the mobo back to just the PSU and the CPU, which I've tried with two different CPUs, an i3 and an i5. With no RAM in place, I get one long beep, then two short beeps, which is my BIOS's code for "hey, there's no RAM here!", so that's as expected. All fans are whirring, including the CPU's own fan.

When I add some RAM though, total silence. I've two 4Gig DIMMs to go in 4 slots. I've tried every combination of slots, with both DIMMs and with only one DIMM. I'm sure the DIMMs are pushed in all they way, because if they're not, I get the one long, two short beep "no RAM" sequence again. These are not new DIMMS either: they've been working for 3 or 4 years in this system.

I've tried resetting CMOS, both via the jumper connector and popping out the CMOS battery. No difference.

I'm thinking it's probably the end of the line for this system (or most of it, anyway).

Did you connect the power cable from the PSU to the RX570?

On what surface is the motherboard while testing?

Did you try the other PCIe slot again with the old GPU? Resetted Cmos again ?
Was the GPU 1st installed in the black PCIe slot ?

Which power supply are you using?

Thanks for replying, @helpstar.

I ended up taking the system in to the local computer store, who confirmed the mobo was dead. I now have a completely new system,

Thanks for the feedback anyways. Have fun with your new rig
