Iguess this trouble is happening due to bad RAM. get rid of RAM fromCPU board and clean it and then directed the RAM again in the CPUboard. If this does’nt exploit for you, then it might beapproximately internal trouble of RAM. The beep faults concern to a"Base 64K RAM failure”. If you acquire 3 beeps then it isemphatically a RAM trouble. If your RAM is below warranty period thenit will acquire substitute, but make sure that you accept a RAMtrouble nothing else.

Whencomputer beeps 3 times at the startup then it entails itinterpretation storage fault, which means one of the storage sticksis bad. You accept to assure your RAM storage 1st, take out your RAMfrom the CPU board and clean it with approximately air pressureinstrumentality and placed it into the CPU board after stripping it.Assure that your trouble has decided or not, if not, then try toinquire approximately hardware techie it will help you.

Theprimary cause for fault beeps is a failing PSU. You accept to detectout 1st why this fault beeps is happening in post. There is not a 1cause for that it might be your RAM trouble or something else. Afailing PSU can case this trouble but not sure. If the PSU is indeedbad then your computer would’nt post at all. If you don’t detectthe exact result of your trouble then you can call to a servicecenter or a hardware techie.
