Custom built PC not booting

[Orbixas]

Hi!
So I have recently upgraded my computer from an MSI mobo and an AMD FX 6300 to an MSI GAMING M7 Z170 mobo and i5 6600k + the new ddr4 ram and I have had a bit of trouble lately.

I had a hard time booting it in the beginning, but then I tried removing obe of the RAM sticks and it worked, looked like my old PSU wasn't enough (500W for GTX 970, i5 6600k, the mobo, 1 hdd, 1 ssd, fans, 16gb of ddr4 2666ghz ram and a dvd rom)
Then when I wanted to boot it again I wasn't able to get to the bios, I unplugged my hdd's power and SATA cable and it worked, but it was very unstable. (I got blue screens every now and then) I tried disconnecting the dvd rom and it worked for a while until it stopped working again. I tried replacing ram, unplugging everything else than my psu and my monitor from the power extender (or what it's called, it goes from the wall and extends out to 4 new power outtakes) and it still didn't work.
Then I tried unplugging my GTX 970 and connecting to onboard gfx, didn't work, but when I reconnected it again it worked but again it was very unstable. I tried reconnecting my hdd, didn't work, I disconnected it and got it up and going like last time but then accidentally dropped my pc, only about 7" though, but I got a blue screen and it hasn't been willing to boot adter that. (Fans are running, lights on the gpu are on, case lights are on, but caps lock isn't working and no monitor output)

Did I screw up? There is already a new PSU incoming (I ordered a 850w one when the 2 sticks of ram didn't work, enough for future sli) if it doesn't fix it what do you think is the case?

Hi, I suggest re-seating the CPU and checking the CPU socket. See if any bent pin.

You're right on the edge with a 500W PS, so that could very well be what is causing the instability (especially if it is a cheap one).

Try out the new one. If you can get to the BIOS then I would try setting it to default or optimized. If you can't get into BIOS, then try clearing the CMOS.

If it still doesn't work at that point, and you've ruled out the RAM or CPU (make sure its fan is working), then it might be the MB.

I'm not sure what PS you got, but I would make sure it is at least Bronze rated at minimum. The PS is arguably the most important part of your computer, because if it fails, it can take all your other hardware with it.

Is it possible to bend pins on the intel socket? I knew it was possible with the AMD ones with the pins on the bottom of the CPU, but the intel one?

Thanks for the reply, gravitybell07, I'll update the post when I get the new PSU.
The one I have now turned out to be a Cooler Master Thunder 500W which shocked me as it is not even Bronze rated!
The one I've ordered is a Corsair 850M with Gold rating, hope that works.

Checked again, the new psu is RM850M.

It doesn't seem to work, though I must've connected something incorrectly, or just not connected something. MOBO lights are on, CPU and GPU fans are on, but the case fans and backlights wont't turn on. (I thought they were connected to the motherboard, not sure..?

I've checked CPU power and ATX power just fyi.

If you're still having issues, then here's a good guide that someone else put together for this sort of problem.
