computer starts beeping every 3- 10 seconds

Please help. I use my computer to produce wedding videos and I cannot afford to have it crash. Please help me understand how I can fix this. I don't know what the beeping code is.

I just "air" cleaned the inside of the cpu out about 4 months ago. Maybe a fan is dying? Maybe its my monitor? I have read the other forums but cannot figure it out.

When it starts beeping, other programs are slow to react and it won't shut down properly.

Thank you so much,
Joanie

When it beeps is it 1 long beep or a series ?

It sounds like a CPU overheating issue.

I would open the case & inspect the CPU heatsink/fan & see if they are dirty.
I would also start the unit with the case open & watch the fan to see if it is spinning properly.

One other thing you can do is download a utility that monitors the temperature & install it.

PC Wizard is aq small system info utility that will show the temps [provide the chipset has the feature]

Once it's installed open it & click on the icon in the lower right that looks like a temp gauge.
Post the Processor temp.

If you minimize PC Wizard to the taskbar it will show the temp in the upper right corner of the monitor & you can see if the CPU is overheating when the unit starts beeping.
