So looking thru the manual and online forums i reinserted the RAM, reset the BIOS using the jumpers and took out the battery. Finally getting it to work pushing the MEMok button and getting into the BIOS. Since that day i have had no issues, so around 3 months, until last night. I was playing f1 2011 online and had been without issue for 2 hours prior when the PC froze! i went to reset the PC and after booting for 1 second or so, it shut down and reset, stalling. So i opened the case to find once again the DRAM light a solid red. So to my annoyance i had a quick look reseating the RAM but to no avail. This morning i have spent multiple hours reseating my 2 sticks of Corsair 1600MHz RAM, changing jumpers, clearing the BIOS, unseating all the hardware. There are no signs of cosmetic damage to anything. I have done the MEMOK test 100times changing the modules into different slots, 1 at a time, 2 at a time. I tried with no memory in the PC and that continued to beep so i know that is working. I tried the ASUS websites FAQ section about 1600MHz RAM by turning off the PC, unplugging and switching jumpers. Is there anything else i can do? I am at my wits end and dont know whether changing to 1333MHz RAM is going to help to fix the problem ( as 1600MHz has worked without problem for 3 months) or whether the motherboard has become faulty and is in need of replacement. I hope you can resolve my issue.
