Beeps always indicate error excluding a one single beep only which indicate process.Every manufacturer has its own beep setting. it comprises on short and long beeps. If previously it working good, then your idea may be correct. replace both the keyboard and mouse with existing. start computer if now it not giving beeps it meant that one of them is causing problem. connect one by one and start computer you will reach. AND if even after replacing keyboard and mouse it gave beeps then shut down your system. Open casing remove processor and memory chip out and connect them again it will work now INSHALLAH.

Beep beep beep


Temporary Fix: unplug the dryer or cut its power at the circuit breaker panel, when not in use. If the dryer alerts/alarms are set to silent and the beeping happens when it's not in use, chances are it's the same beeping you hear when you first introduce power to the unit or press start. This may indicate a short affecting the control board. If you need to press start multiple times to get the dryer started, then the control board components are most likely starting to fail.

3 long beeps normally indicate defective memory or loose memory on DIMM so take out and insert it again or you need to replace with new memory module. Where as fast beeping indicates Graphics error and need to change the graphic card

If this dont fix please tell me
Best Luck!
