I bought a new motherboard, CPU, and RAM for a new build and when i put them together a red LED light lit up indicating that it can't read the RAM. I only bought 1 RAM because i was tight on the budget. I even get the error beep code of 1 long and 2 short beeps. I looked it up and it did say that it indicated memory issue. So I went to replace the RAM but it still didn't work. I'm beginning to suspect bad memory slots and may have to return the MOBO. I haven't tried resetting the CMOS though, will that help? and I have a friend coming over to test his RAMs on the motherboard.
