2 beeps - Parity error - bad memory

[Zerkan]

How can I fix this?

The mobo is Z68A-GD55 (G3), it beeps 2 times, 3 times without ram installed and no post, ive tried all slots with different ram and cleared cmos.

I dont use any gpu just the igpu

[goto10]

try with other ram modules, see if that helps

 

remove battery, then clear cmos

 

check ram modules on another pc to see if those work

I have tried different modules and same problem, and ive cleared cmos aswell 

[goto10]

then it is, well, was the motherbpard

 

just to discard before going to buy anotjrr motherboard, reseat cpu and try with another psu to see if it helps

 

do the same with gpu, try with everything unpligged, hard disks, ssds, sound cards if you have, only keyboard, mouse and monitor, but sounds to me is the motherboard
