Solid Asus DRAM_LED.

Hello there.

Just looking for some thoughts on an issue I've ran into. I put together my latest build about 6 months ago, and it ran fine up until recently. While playing a game I had a crash, after which it would not post. Upon inspection I noticed the DRAM_LED was on. I've tried a few things to resolve this, at first I spent awhile just re-seating the mobo and running Asus' MemOK, when this didn't get me anywhere I ordered some new ram however the problem remained. I decided to get a new mobo which arrived today, and after setting it all up the DRAM_LED/no post seems to have remained. You guys think I should just assume it's the CPU? Any of you have experience with the DRAM_LED indicating an issue with the processor?

Build:
i5 2500k
Original mobo: P8H61-M Pro, Replacement mobo: P8Z77-V LX
Original RAM: Kingston 8GB 1333Mhz HyperX Blu, Replacement RAM:Corsair 8GB 1333MHz XMS3
Radeon HD6870

Thanks,
~Friction.
