recently recieved a new intel DX79SR from an RMA due to my old one going out. well i installed everything back into it as it was previously and now on top of what appears to be my heatsink(h20 920) going out, my computer is blinking red the WD Fire LED on the motherboard. i tried reapplying thermal paste checking the temp of the processor to make sure it wasn't overheating and it still does this it was also giving 3 long beeps but i moved the ram around a bit and that fixed the beeps. i'm actually wondering if the heatsink is the issue or if the motherboard is defective at this point. also it was odd if i had the memory in certain slots it would read as defective ram but moving them into different slots made it read as functioning. wondering if on top of this WD fire LED blinking if the memory slots themselves aren't defective.
