PC Won't start

[OrbitMatt]

Hey, I was playing games on my pc when it suddenly froze, I went downstairs for a bit (waiting to see if it unfroze) and when I got back upstairs it was still frozen. I forced off the pc and left it until the morning. When I woke up and tried to turn it on I found that the pc started up but the monitors showed as if the pc hadn't started. Then the pc shut off and on and off between about 5-10 second intervals. Can someone please help me work out how to fix it and tell me if I need to buy any new components. Thanks.

 

Things I have tried:

-Taking out the gpu and trying the monitor on the cpu.

Reseat the GPU. That has worked for me before.

Try a different pci slot, too.

Interesting. Do you have another computer, and a spare hard drive (does not need to be fancy or large 160 or smaller will do) ? If you have both what you can do is download the windows 10 Media creation tool to create a bootable USB drive with windows 10. Then take your current hard drive, "out" and install the spare hard drive, then insert the bootable USB, and boot to it. Proceed through the process of installing windows 10 onto your spare drive, (no COA or Activation required) then go grab Aida64 or Prime95, Stress the system out for 6+ hours. While that is happening take the other hard drive and see if there is a memory dump file. If there is then see if anyone here can debug it for you. I unfortunately cannot... Visual Studio and windows Debug tools hate me and my workstations. Also while waiting for the media creation tool to download and create a bootable USB, run MEMTEST (7.1) on the system. Also using Crystal Disk (info) not benchmark check to see if you drive is good or not. 

I have added links below for various tools.

I hope this helps. Also run the system without the GPU or check the GPU fans to see if they are spinning or not.

Tried the 1 stick of RAM at a time and no luck. Also shouldn't the PC work without a gpu? With the monitor plugged into the CPU? Surely it doesn't matter if you have a gpu or not.

do you have integrated graphics on motherboard? if so try that..

also the ram test of 1 stick a time tests for a faulty ram stick.

does the pc beep when booting , if so how many times or does it have a led display on mobo(whats it show).

 

plz supply system specs so I can give a definitive answers
