    7-The computer is on a CyberPower UPS

    2 days ago I went to fire up my computer (which has run very well for many years now) but it wouldn’t boot even though all fans started and continued to run. So I held the power button in for a couple of seconds and it shut off. I tried again and it brought up the BIOS screen and said that Overclocking had failed so I pressed F1 to go into BIOS and loaded “Optimized Default” and saved and exited. It seemed fine for that day.
    Yesterday I went to boot it and no boot again with all fans running and the HD light lit for a second but quit. I tried to do the same thing as the day before but this time it didn’t work and it won’t boot period no matter how many times I tried.

    What would be my next step?? Thanks for any responses in advance.

      I suspect what you had was a “long POST”, as something wasn’t responding.

      It gets common when a optical drive gets flaky.

      The error you say isn’t a diagnosis – more a message indicating POST did not complete so it could even be a “one off” or a dirty contact reseating all the parts might see resolved.

      On outside chance if you leave the PC on standby a lot is the SB5V supply is getting weak or unstable so when you power it up, power good (grey wire) goes low holding the machine in reset as a result, but meanwhile the juice is warming the failing capacitor there so it stops behaving badly and the PSU can start properly next time around. Peer through the fan (Removing the PSU lid NOT recommended – high voltages are stored within even if you unplug it) and look for any metal toped components with a cross on top where the cross is pushed out, or even split open with gunge escaping. If you see those a new PSU is probably a good start even if the fault proves to be elsewhere! They’ll likely be in the circled area between the smaller sized transformer (yellow square thing) and the power cables (visible green wire in attached photo is 5V standby)

      Weird behaviour like what you describe sounds very much like a faulty memory dim..
      step and repeat process: First switch off power to the PC then remove memory dim in slot 4 (taking anti-static precautions – ground yourself first before handling dimms) then try to boot the PC once power is switched back on again. If it still does not boot, power off, replace dim 4 and remove dim from slot 3 and repeat until the system boots.
      If the empty memory slot is in 3-4 that’s ok for now, if in slots 1-2 swap out and use in slots 1-2 assuming the dimms are all the same;
      Dual channel memmory will suffer beyond 16Gb for now until a replacement is inserted.

      Can’t get to either of the recommendations right away but will try them and report back later.

      Thanks to both of you for responding ๐Ÿ™‚

      It’s fixed.

      There’s 4X8= 32 GB of matched Corsair Ram in it and the ASUS MB has a MEM OK button so I gave the MB power and pressed the MEM OK button and after a bit the POST screen came up and only showed 3 sticks of RAM so I puled the “B” set of RAM modules out leaving 16 GB of RAM and it now boots fine.

      Looks like you nailed it Microfix. I’m sure glad that ASUS had the MEM OK button on the MB because it was a short diagnosis.

      Thanks for all replies ๐Ÿ™‚
