I picked up this motherboard. When I try to boot it .The motherboard stop at the ASUS boot screen and that`s it . No keyboard, light comes on for it that`s all .Does anyone have an idea where to start looking for the problem? I have a bios chip programmer .That has been done and tried from the first to the last bios and new bios chip. Where to look for the problem ?

Clear the CMOS. And if you're using all 4 slots (if 4 slots on motherboard)
go into BIOS and raise the DRAM voltage to 1.90 V, if it's DDR2, with 2 of the RAM sticks removed. Then insert the remaining RAM afterwards...
For socket 1155:
Clear the CMOS.
If using 4 sticks, take 2 of them out and depending on the RAM, manually setting the DRAM voltage to 1.65 V, before inserting the remaining 2 DDR3 SDRAM sticks, may solve the problem...Last edited by RJARRRPCGP; 01-23-2018, 09:36 PM.ASRock B550 PG Velocita

Re: Asus p8z77 v lx
I can not get into the Bios at all, the keyboard stops working .The lights on it come on and that is all> I have tried a p/2 keyboard and usb no luck with either. As it starts to boot I can get the caps lock key to work and that stops, as soon as boot Asus screen comes up .All the socket pins look good and straight. I have tried changing out ram and, CPU, power supply nothing changes

Re: Asus p8z77 v lx
Clear the Bios settings using the jumper provided on the mainboard. try to find it. There are lots of easy solutions which you can try one by one. If you got no result, you can think of reprogramming the Bios chip. But first, make a backup of the original content of the Bios chip.

That's at least when using my Corsair Strafe keyboard on my Asus P6T Deluxe.....Last edited by RJARRRPCGP; 01-27-2018, 05:23 PM.ASRock B550 PG Velocita

Re: Asus p8z77 v lx
Before attempting a BIOS reprogramming, try the simple stuff first. Namely, that's:
- strip down system to minimum hardware: CPU, CPU heatsink, *one* stick of RAM only, onboard GPU (may use PCI-E GPU if board still doesn't boot after below tests).
- re-seat RAM a few times. Try different RAM slots. Use good quality RAM, if possible - i.e. Samsung or Hynix OEM. Kingston and Crucial is okay. Corsair I wouldn't trust.
- re-seat CPU and also try running board flat with CPU heatsink on the CPU but not clamped to the board (this is to prevent board warping, which can sometimes affect marginal CPU socket BGA).
- re-check all jumper settings
- make sure CMOS CR2032 battery has good voltage (at least 2.9V) - some boards may refuse to boot with a drained or no battery... though I suspect that's NOT the problem with your board)
- make sure you are using a known good PSU. In fact, please tell us what PSU you are using (manufacturer and model).
- check and possibly replace chipset heatsink thermal compound
- try the "MemOK" button (I doubt that would do anything, but what the heck!)
If none of that does anything, you can try reprogramming the BIOS. But do try to backup the old one first, as caspian suggested.

Probably better if you post pictures of your board and specifically point out which MOSFETs read shorted (and how). That should tell us if there is possibly a problem or not.

Re: Asus p8z77 v lx
Boardview if this is of any use.
If there was an issue with the RAM power supply circuit, you won't get an image and BIOS POST would fail when detecting the RAM.
But first identify which MOSFET you measured and what did you measure.Attached FilesOpenBoardView — https://github.com/OpenBoardView/OpenBoardView
