PC won't boot after shutting down (have to CMOS reset)

Title pretty much describes it,
Yesterday i upgraded my system with new ram (dominator platinum ddr3 -16gb - 1600 Mhz)
Had troubles booting up, but got everything fired up after a simple CMOS reset. PC ran just fine.
Went into the BIOS and put my ram on XMP, made changes to the system fans like it was before.
Pc booted up and worked just fine.

After this if i wanted to shut down my computer, my pc just wont turn on after pressing the power button. I have to reset my CMOS everytime to get it working again. This was an issue i never had before. (well not like this) previously if i made a change into the BIOS the pc lost power and turned back on. Now it just stays turned off and i have to reset my CMOS again...
I also tried shorting out the CMOS reset switch and taking out the battery.

I really have no clue what's the issue here.. PC worked fine when new ram was installed except after making changes into the BIOS. Maybe a dead CMOS batery? corrupt BIOS?

  1. You could be on the money with the CMOS battery, try fitting a new one.

    They only cost pocket money anyway, so makes sense to try that first.

    But it would be coincedence that it failed just when i got my new ram wouldn't it? D: Il try and find on in a local shop,
    Il keep this updated as soon as i have news
  3. Have you tried to switch back to the old ram to see if you still have the same problem

    That's something i might have to try. Thought it would make sense if my pc didn't detect it my new ram, but it does.
    I will try that tho!
  5. So i had some new 3V batteries and tried with these, same issue. Can't boot without CMOS reset.
    Changed my ram to my old sticks and nothing different happend.. Still having the same issue. Tried flashing bios again..
    just before the BIOS update (when the pc has to reset) it just turned off and nothing happend. I can't turn it on, took the cmos battery out and am going to wait a little to put it back in.. This really doesn't sound all to good. I just wanted to upgrade my ram.... :(

    UPDATE: got pc fired up again. Restored system defaults in BIOS. This might of fixed it, (testing with old ram). I will update if i know more.

    UPDATE: problem was not fixed.
  6. Needs some more expert input then, i suggest you please start a new thread making sure you explain what you've already tried so you don't end up going over old ground.

    On which sub forum do i have to post it?
  8. So i contacted my hardware store a week ago and i rma'd my motherboard, cpu and ram. They contacted me to say that everything was okay and was working perfectly. They tried to replicate the problem multiple different times but it always booted without any issue. So my guess here is that my psu could be bad or there was a shorted out circuit somewhere in my case. It could also be my power button that is stuck?? Anyways, i will get my hardware in a couple days and keep this updated!
