    Other than the need to reset the bios everytime it sounds like a power supply problem.

    Does it behave the same way without resetting the bios?

          I'd say you still have some failing capacitors - probably in the VRM.

            Ohhhhh, that makes sense. If the power isn't interrupted at the PSU then it's getting interrupted at the board.

            Is it possible that the wrong value cap was used as a replacement?

            "the caps around behind the VGA slot"??? The ones by the Northbridge?

              if it has elite or ost on vrm output replace them.
              last 3 of those boards acted posessed till i recapped.
              were not bulging but sizzled and stunk when i pulled them.

                Hurrm....guys i think i really messup the caps 1500uf 6.3v 105*c to 1500uF 6.3v 85*c..... damn.... now i changed it to the same value...now the problem is the FET transistor getting hot (around 50-60*c) where you guys can see there is caps between the FET (left on VGA slot in the picture of the MOBO) is it the FET having problem or it was just normal coz now it can posting....

                  While working on my Acer Aspire with the OS failing to load, I encountered a motherboard number of DA0ZHQMB6E 0 REV: E. I was getting nowhere fast or slow, for that matter.

                  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...

                  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:

                  ASUS Zephyrus GA401I Severe Lag, Suspect Motherboard/Power Issue - Need Help Diagnosing
                  by MakNCheese
                  Hi everyone,

                  I'm having a serious issue with my ASUS Zephyrus GA401I (4 years old, worked perfectly until recently). The system is lagging heavily, even in the BIOS, and is charging extremely slowly (a few percent in hours), making it nearly unusable. I suspect a motherboard or power delivery issue.

                  Symptoms:
                  • Severe lag across the system, including BIOS navigation.
                  • Slow boot times and unresponsive performance in Windows.
                  • Battery charges very slowly (e.g., ~5% in 2–3 hours).
                  • No error messages or BSODs, just extreme sluggishness.

                  What I've Tried:
                  • Replaced
                  ...
