PC won't boot up!

Hi.
So today,i bought a new pc.
It's an Intel Core i7 2600 with 8 gbs of ram and a 500 gb hard drive. Everything was fine,i updated my video card drivers (its an integrated intel hd),updated the windows to the latest version.
After about 4 5 hours of playing some euro truck simulator,and downloading some other game,In the middle of downloading,the pc turned off. I turned on the pc again,and continued downloading again. Then again after a minute,i got a blue screen saying the pc has ran into an error and that it will self restart. I turned it off from the power source..
Now,when i boot my pc,it sounds normal,but my monitor shows no signal. Im sure it isn't the vga's cable fault or something. Then after 30 40 seconds the fans turn REALLY loud,all of them apparently. It just sits like that loudly,displaying no image. I saw some other forums and tried switching the ram sticks places,didn't work. I checked inside,everything looks brand new and clear,no dust no anything. Also,if i put out ram,i can hear a loud beep. That apparently shows that the issue isn't in the motherboard? Can anyone help me? I can take a picture of the inside or provide additional information.
Thanks in advance.

 

2600k is about 9 years old now so what is new to you is ok but when it comes to a rig with a no-boot there is more at play and you can't conclude that it's not a cable or anything else. The starting point would be to list the power supply you're using (make-model-specifications). Did you try any other cable? usually most mainboards that support that series of CPU have DVI - Analog - sometimes HDMI on the mainboard back IO.

Start with this;

Motherboard make and model
PSU make and model
OS (win 10/ win7/ win8 etc)


-yes you can provide pictures
