I decided to add ram so i installed 2- 1g sticks.... started up comp and monitor and keyboard arent turning on?? removed new ram and put old back in---same thing...tried another monitor-nothing.. Has AMD Athlon 64 ... 3400 processor... Hear a longish beep then pause then another longish beep at startup...Any help would be appreciated-I really need this comp to run..
