I have this problem with my computer. Almost everytime I leave my computer running and unattended, like overnight, I come back to an error that reads "Insufficient System Resources Exist To Complete The API". The message is in a box with an 'OK' button to click. When I click the button it does nothing but make a loud beep. All I can do is hold the start button down and reboot. Everything else seems to be running ok. It's hard to know what to do when I don"t even know what the API is. I am running Windows XP. Can anyone please advise me on this?
