    You don't. It will not function at all without a processor. You can power it up, but it will do absolutely nothing.

      Actually they do make CPU simulators that fit in the socket. You can power on the board and it has LED's on the PCB to indicate which pins are getting power and if I recall correctly test points for your multimeter.

      It wont tell you if a board is good or bad, but at least it will let you know if the CPU is getting power.

              find some... or at least set the mobo flat and set the heatsink on the cpu. make sure it well centered. don't OC or push it too much. only do it long enough to run the test.

                  I use zip ties if it's only temporary. I did it on my main PC for like 2 months with a heavy tower cooler and the motherboard on its side in the case. It worked fine untill I got the TX3
                  I love putting bad caps and flat batteries in fire and watching them explode!!

                  No wonder it doesn't work! You installed the jumper wires backwards

                    Asus ROG Strix Scar G533qm with a G733qm Motherboard, can I modify the Bios to accept G533 Bios
                    by glovecaps
                    Hello,

                    I have a Asus ROG Strix Scar 15 (G533QM) that had a dead motherboard (Graphics card dead) and after trying to fix the motherboard with no success, I bit the bullet on a sale for a new motherboard. I ordered a motherboard for the 15 inch model which is the one that I have, and when the motherboard arrived it wasn't for a little while that I saw it was from the 17 inch model.

                    My question is, can I update the Bios on this G733 motherboard to a G533 Bios.

                    The reason for wanting to do this is that the keyboard isn't working as it should, and I think this...

                    Legion Y540 17irh motherboard issue ( need help to know how to diagnose my motherboard)
                    by Docus
                    Hi everyone 😀,

                    I'm here today to ask for help with repairing the motherboard of a Lenovo Legion Y540 17IRH.

                    To give you some context, I'm passionate about computer repair so much so that I've invested in a lot of tools and started practicing on dead and old hardware. I've been learning how to solder and desolder components, mostly focusing on phone repairs.

                    Recently, I bought a broken Lenovo Legion Y540 17IRH for just €150, and there are two main reasons why I made this purchase:
                    1. I already own the exact same model, but its plastic chassis is badly damaged.

                    ASUS P5GC-MX motherboard recap
                    by momaka
                    Here’s another motherboard that needed a full recap: an ASUS P5GC-MX.
                    This one was gifted to me some years ago by user Pentium 4, along with a few other goodies. It actually came in working order with no bulging or leaking caps. However, I noted there were United Chemicon KZG caps everywhere on the motherboard. The CPU VRM output (CPU V_core) was the only exception: it had only 2x KZG. The rest was 6x UCC TMV 4V 680 uF caps… which aren’t any good news either.

                    So here is what the motherboard looked like with its original caps:

                    I made the test stand out of a neighbors discarded case that had no covers.
                    the pictures might be out of order. the weld does not look pretty kept burning through.
