Having problems with your PC Desktops ?

CPU bleeping constantly.

\015 After being moved my grandsons computer when put back on bleeped constantly. Tried all the leads - changed them over to his sisters who has the same set up but to no avail. Could dust in the CPU do this or do you think something inside has become dislodged.\015\012\015\012The monitor just come on (blue light) says Acer and then no signal and then the light turns orange. Still the bleeping goes on.\015\012\015\012Help. A Nanny in distress...\015

Answers :

Yes that means the computer has failed POST. So yes, something has come loose or has got damaged.
\015\012
\015\012"POST" is an acronym for Power On Self-Test. The POST process checks the basic system functions before attempting to load an operating system. It checks RAM, processor, drives, system interface, etc. If POST fails, the system will normally halt and may produce a series of beeps from the computer speaker which can help indicate the cause of the problem.
