Need help quick! Dell computer not turning on
Ok, just bought a used Dell Precision 340 to use in the shop, and when I turn it on, it makes a beeping sound, and the "a" and "b" lights on the back are amber, while the "c" and "d" are green. It won't do anything.
What is causing this? I know the computer was working a few weeks ago. All the guy did was unplug it and set it in the closet.
Please help. thanks.
