I have an officejet 4580 on my hp desktop and I mainly use it for scanning in business documents. I have never had any problems before but yesterday it started shutting down my computer automatically after 8 pages. I use the feeder on the top of the printer to scan.

I sat on the phone with hp for 4 hours while they took over my computer and tried uninstalling and reinstalling the printer software. This did not work, and my computer is still shutting down after scanning 8 pages.

Hp said the cause may be that my ram is too full and its not allowing me to temporarily store the that much information.

Is this true? If so how do I free up ram space and if not, what could the problem be?
Help me please!

Define "shut down". Does it actually go through the shut down procedure like if you selected shut down from the start menu or does it just turn off? Do you get a blue screen or does it freeze? Please also tell us more about your computer.
