Pc was happily working with 2 ram sticks. One day I replace thermal compound of cpu by moving out of mobo and fix it with same stock cooler. Then I start pc but pc didnt boot and given beeps.
I remove 1 of ram stick then it started. Then I check second ram by removing ist n install 2nd in same place, pc again started. I swap install ram both sticks in dual way but again didn't boot.
I mean 1 stick is only supported at a time by mobo. Both stick working but when only one is installed. Mobo ram slots also working bcoz i tried single stick in different slots n pc boots ok.
I think some bios settings must b changed automatically. Bcoz all hardware ok.
Plz help if u can find the way so i can again use both sticks same time.
