PC not booting (Beepcodes if no RAM but no video if RAM is in)

[Margott247]

Hello, as the title says. Ive just built a pc and it refuses to display. Neither from the igpu nor from the dgpu. When i take the ram out, the pc gives 3 long beeps (ram issue) but when i input any ram, it doesnt do any beepcodes and doesnt beep.

Specs:

intel desktop board dh55tc

i3-520

2x4GB DDR3 1333

AMD HD 5850

Rexpower 400W PSU (w/2x6pin pci-e)

 

I have tried reseating the memory, tried different memory, tried to boot without dgpu and also tried a different PSU - Fortron Hexa 500

Did you clear cmos? 

 

I mean you shouldn't need to with a new build but it may help with your issue.

I didnt, ill try to now

Ok i checked and i dont see anything that is connecting the jumpers as in this picture. There is no red thing like that, just 3 pins. Could this cause the issue?

Hmm,  yeah that could be but I'm not sure,  hopefully someone else knows. 

 That seems strange for sure.

Im so ashamed of myself, that actually worked. I placed a jumper on it and the pc now boots ok and displays. Im so sorry for bothering

Ah, cool, glad it helped. No problem! 

 

Well it's not really your fault if that jumper was missing.
