When I start up my PC and I have 2 sticks of RAM, it gives me 2 beeps, but when I remove one and it's just one in, it starts up just fine, no problems at all. If I were to leave both on it will start up and after it will either reboot, or give me a group of squiggly lines. It's getting very annoying. I have little bit knowledge of computer, but I can't work with the BIOS at all. I have a BIOSTAR TA790GXE 128M with an AMD Athlon (TM) II x3 425 processor. If you are having any suggestions then reply me. Thanks in advanced.
