As you can see from the title my computer won't turn on. There is this 6 pin PCI express power cable that is unplugged. Does this affect if the computer will turn on? Additionally, I don't know where to plug it in to on the motherboard. You can ask me to send pictures of my motherboard and the pin.

that 6 pin power cable doesn't go into the motherboard the -pin is for a video card or an add-in PCI card that requires it's own power. and no it should not affect the computer turning on.

 

im not sure what you mean by the power button is on, the LED around the power light to indicate the machine is getting power?

 

there is however a 4 pin (normally yellow and black) that plugs in near the back panel that gives power to the USB, On board video, etc.

Thank you and yes the LED on the power light is on. does it mean that the motherboard is properly working and the system is getting power?

very few boards have the 6 pin instead of the 4 pin, so double check that.

 

and if the light is on it's getting power.

 

and if its getting power, but the machine is not turning on then you should re-seat the RAM and HDD, and see if that makes a difference, if nothing still, time to test each component

I reseted the RAM, but not the HDD because I don't know how to reset it. I also just opened the ram sockets and just put the ram back in. Is that a proper way?

What gpu do you have? Is there an open plug on the gpu? Try clearing the cmos. Remove the watch battery for a few seconds and put it back in.

Do you have the 8-pin power connector on the motherboard plugged in to the PSU?  This 12V connector is to power the CPU.

 

Your motherboard has the following connectors.

 

ATX 24-Pin power connector
8-pin ATX 12V power connector
2 x 3-pin system fan connector
2 x 4-pin CPU fan connectors
1 x 4-pin system fan connector
1 x Clear CMOS jumper
1 x Serial port connector
1 x Parallel port connector
1 x TPM Module connector
1 x Front Panel Audio connector
2 x System panel connectors
1 x Chassis Intrusion connector
