My pc won't turn on HELP!!!

[SantaOnRs]

The other day I loaded a game (SMITE) and half way through a game the screen went navy blue and I knew my game had crashed ( this has never happened before) so I tried turning off my pc and them turned the power from the wall off, then when I tried turning my pc on it didn't work so I tried 3 more time and it worked so I tried SMITE again and it worked for about 10mins before crashing again, I tried loading smite 3 more times (after turning my pc off then on) but it kept crashing so I thought SMITE was just crashing even though my pc can easily handle it at max settings, I then tried watching a film it went fine for half of it before crashing again and since then my pc won't turn on. This problem only happened after half of the day went by, the only 2 things that I think it could be is that 1. I recently updated my AMD drivers because before then nothing like this had ever happened. 2. I have been using Windows 10 insider preview. These probably aren't the problem but I need help fast!!!! (Here's my build: https://uk.pcpartpicker.com/user/WhatIsPc/saved/
(it's the one listed as my first build)

im not a huge expert on this type of thing by any means so i may be wrong but i would say try going back to you original OS(win 8 or 7 i assume) and then try it. if its not that it may be the drivers so try updating them or going back to your previous driver and see if that helps. the driver may not like working with win 10 for some reason. i think your right about the two things you think it may be so i hope i gave you some help on what it might be. Good luck

Weanis is on the right track, but if you can't get your PC to turn on, you won't be rolling back your OS. Start with some basic troubleshooting steps:

1. Open up that case and remove the CMOS (CR2032) battery for about 10 seconds. Reinsert battery and try turning on again. No change? Move on...
2. Disconnect all devices unnecessary to POST (everything but CPU, 1 DIMM, PSU, & GPU (unless you have integrated graphics, then disconnect GPU). Power on your computer. If you get your system to power up, there's a good chance your PSU is failing, so test it with a digital voltmeter or multimeter. If you don't get your system to show signs of life, try "The Paperclip Test" - disconnect the P1 connector from your mobo; turn off the I\O switch on the back; stick on end of a paperclip into Pin 16 (the only green wire); stick the other end into any neighboring black wire (Pin 17, for example); and finally, flip the switch back on. Does your PSU power up? If not, replace it. If it does, this is known as a false positive, so test it with a multimeter.
