When my pc turns on it constalty makes beeping sounds and doesnt stop the diaplay doesnt turn on,the monitor works fine

The 5 beeps is a memory or motherboard problem. I would remove all but one of the memory modules and test each one individually and find the one that may be bad.If the PC beeps 5 times with all of the single memory modules tested at a time, then the motherboard is shot. Hope this helps
