Dead CPU or RAM? Won't POST.

Justin5609 · Mar 1, 2014

So my PC would freeze at the motherboard splash screen and then just go to a blank screen with a flashing " - " in the top left corner and stay like it.

I assumed it to be my motherboard so I RMA'd it, Gigabyte just sent me a response saying it's fine.
I put my 850W Consair PSU, GTX 770 in my parent's PC and it's working fine.
I guess that narrows it down to my CPU/RAM, the RAM won't fit in my parent's PC so I guess ill have to wait to test them; in the mean time does anyone have any ideas of what I could do to confirm which one it is?
My build is;

EVGA SC GTX770 2GB
Consair 8GB DDR3 RAM
Consair 850W PSU
Intel i7 3820
Gigabyte x79-UP4 socket 2011 motherboard

Try taking out all your ram and put 1 in at a time and see if one is faulty

Did you look at this?

does your ram occupy the second slots taken from the cpu away/out? I assume,since you've got 8bg's,that you've got 2x4gb's?

Yeah. My PC wasn't opened or touched on the inside since September and has been working fine ever since; I just came home to the problem. I unhooked everything and put it all back together and the exact same thing happened. The RAM and everything was slotted correctly.

I believe I tried the RAM thing before I sent my mobo off, but I'll try it again when it gets back. I couldn't use memtest because I couldn't get into the BIOS to even try to boot from DVD.

If the CPU is dead I should hear a beeping correct? it didn't come with a case speaker so I guess i'll need one of these?

Can you do a clear cmos via the right jumper? Or take the motherboard battery out for a few minutes.

It should probably be noted too I couldn't access the BIOS, it just wouldn't go into it. Not sure if that leans closer towards it being the CPU or RAM?

So I received my motherboard back today, hooked everything up and it's running better than ever.
Not that it matters but my motherboard splash screen is completely different, just curious on why?
