Pc display cutting off after several seconds

Specs: Windows 10, AMD 8300 / 8gb ddr3 1600
For Christmas I go a new pc case, the computer I have he is an Asus CM1855 with a gtx 770 and atx-CB700w power supply. The computer worked perfectly in its original case and I set in cooler master scout II case so I could upgrade a few things and make my pc look epic. So that being said, when I power on the pc it displays fine, I either get in the BIOS for a few seconds and displays just cuts off, or I get to the windows password screen and it cuts off. Sometimes sooner sometimes later.

Could be overheating.

Try entering the BIOS screens to check the CPU temperature.

If you disturbed the heat sink/cooler you may need to remove it, clean all paste off the CPU and re-apply new paste.

Cpu temp is at 25-30 degrees Celsius, I took the computer out of the case and set it up on the table and right now it is working. I even signed in to my computer so something happened when I put it inside because it works on the table

You may have not installed the required stand-offs into the case. They are needed to keep the board from shorting out.

The stand-offs should be installed behind every screw hole in the board but ONLY behind those holes. Case is probably designed to work with many different ATX & mATX boards.

If the correct stand-offs are installed the board should set flat on all stand-offs and slide thru the rear of the case without need to distort.

If your case doesn't need stand-offs (has raised bosses instead) you may need to install fiber washers between the board and case.

Now I got a different problem, the stand-offs aren't long enough for some of these holes, I looked back at my older case and it has raised bosses and it didn't use standoffs but this one comes with standoffs that simply aren't long enough.

Edit: also my board is micro ATX if that offers anything

Hi Othehilll,

should one of the standoffs be be for earth and if so, metal not plastic.

Mike and Chase

There is ONE screw hole in every motherboard that has a solder ring around it. That serves as the grounding location.

IF, in fact, the included standoffs are too short then they included the wrong ones for that case.

I assume you are using the breakout panel that came with the new case? If not, you need to use it.

Are you trying to install the board with all the add in cards in place?

Look at your motherboard on edge. Is the board flat? Could be that the board is warped and that is why you think the stand offs are short.

At any rate, IF they are too short, DO NOT attempt using the board that way. You can actually break the printed circuit board material by forcing the board into position.

How about posting the brand and model of the new case.
