If started beeping, that is sign of RAM, or CPU issue.
Heat RAM and CPU for test.
You can also try to burn eventually accumulated crap; use quality flux.

If it's beeping, this is trash. Dead CPU, dead PCH, dead RAM, broken internal trace etc. Waste of time.

It beeped when it died according to the customer.
when i test it, It does not beep.
Will try heating ram and cpu and burning crap.
