Hello guys. I just installed an intel core i5 4690 on a Gigabyte GA-H81M-S2H motherboard which is supposed to be compatible. Besides that, I have a power supply of 650W, a graphics card Nvidia gtx 950 and a Ben-Q monitor GL2460 24". The problem is that when I press the on button, the computer like turns on but then nothing shows on screen. I can't even enter the bios. But later when I check the processor it's like he never turned on. I placed him correctly and all that. If anyone comes across any solution, please post it. Thank you all!
