My sons PC has stopped working, its about 16months old.
It still appears to power up, with the RGB fans lighting up but the display doesn't come on and there's no power from the rear or front USB's.
Had a look online and a few suggestions to try include removing the cmos battery for a bit and removing components and booting up each time to see if that makes a difference which ive tire with no luck.
Noticed when i was moving it that the 3 pin power cable felt a bit loose when connected at the back and even a slight nudge in one direction would cause the power to cut off. There was also some crackling when it moved.
So bought a new PSU from amazon,which came tonight fitted it and it was still dead, decided to run through the checks again while the new PSU was connected, starting with RAM and after moving it from one slot to the other it came back to life.
Kept the new PSU in as didn't like the other one being loose and crackling.
However He had left the pc on working as normal, its went to sleep due to inactivity and we are back to the original issue when he has tried to wake it.
Kind of out of ideas now, any suggestions welcomed

So RAM arrived yesterday, fitted it and still the same issue.
Tried removing each component one at a time right down to nothing plugged in. Still the same.
After putting it all back together found a post on line that said to remove the battery and short the CMOS for 1 minute, tried that and it sprung back to life again.
Now the last time it came back to life I hadn't done anything other than remove the battery the night previous but had reinserted and tried to boot with no joy several times after it.
Anyway fitted a new battery and so far so good for the last 24 hours or so.
Surprised as thought the device would still have booted etc with a bad CMOS battery but i guess that maybe its way of telling you it needs replaced.
