Asus p8z77-v lx motherboard
8gb Corsair Ram 2 x 4 GB DDR3
Intel core i5 3350k CPU
Corsair CX750 power supply
To be honest, this is my first time building - all pieces are brand new, recently bought from Amazon. I followed all the instructions on the MOBO manual, turned it on, but then, although I get all the case fans running, nothing appears on the monitor and the DRAM LED light comes on (first it blinks twice then steady on). There is no beep, which I believe is because I don't have a speaker for the motherboard.
I have tried reseating the memory sticks and changing channels at the same time I tried MemOK. The latter did 2 different things: with some combinations, it would do the test (blinking DRAM LED followed by restart - some 3 times or so), then turn the pc on again with a steady DRAM light on. The second thing I experienced was the same testing process but with the PC being turned off at the end of the test.
I have also checked the CPU for bent pins, but it looked normal. Also tried running it with the minimum stuff plugged in (only PSU, no drives, no graphic card), but it didn't work either.
You may have a bad ram slot or stick; try booting with just stick of ram in the slot closest to the cpu. Repeat with each stick until you get a post screen. You may also try removing the motherboard battery for one minute with the power supply unplugged, then replace and try again. A few boards are shipped with the cmos jumper in the wrong position, but this is rare. Check your motherboard manual and see which pins should be covered in the "run" position.
Just tried that (and also each stick independently in each slot), but no result. Same with removing the power supply for the motherboard for one minute. Also checked the CMOS jumper, but it's on the place where the manual says it should be.
