Getting no signal on a new pc,
Amd fx6300
Gigabyte 78lmt-usb3
Crucial 8gb ct102464bd160b 1 stick
Geforce gt640
Evga 500w psu

I have tried another processor, and psu with still no signal also replaced the vga cable This motherboard supports integrated video. Remove video card and use the onboard VGA.  Make sure RAM stick is in slot 0. Make sure the 12V Molex is CONNECTED for CPU power as well as the main power supply connection to motherboard. Attach speaker to the speaker pins of the motherboard of one is not attached to head the beep codes. Maybe your not hearing the POST failure beep codes because nothing is connected to the speaker pins which are located near the front panel pins. Reset RAM as well as a try to get it to boot.Tried in integrated vga slot nothing
No slot 0 it's 1-4
Don't understand the 12v molex part
Speaker is attached Is it this?

See Here...My ram is on the list, I see it Missed it...my apologies...ANYTHING else or am I doomed? It's not Molex ...which may have confused you...it's a 4/6 pin connector right by the CPU...Pcie? The wire coming from the psu labelled Cpu is in the 12v half can fit in or the whole thing, none show signal Cpu fan is plugged in to Cpu fan labelled on the motherboard Quote from: Askall123 on March 20, 2017, 01:20:38 PM
