5. Your computer screen suddenly changes on you. Images and Windows are much bigger than you are used to and everything seems washed out like there are fewer colors to choose from. You suspect there is a problem with your video card, but what else might it be:

The monitor cable may have come loose.

The government may be sweeping your computer looking for terrorist activity.

Your neighbors may be playing "Rock Band" too loudly again.

The dead may be trying to communicate with you.

Your monitor may have run out of color pixels. It is time to bring the monitor in to your service tech to have the color refilled.

While I cannot rule out the possibility that the dead may be trying to communicate with you this way, the most likely option is that the monitor cable to the computer is loose.

7. If you are running out of room on your computer and you don't have any money for new equipment you might be able to:

Purchase and install another hard drive.

Add more memory.

Compress the hard drive.

Format the hard drive.

Hook up a second monitor.

Hooking up another monitor will not give you more space, neither will additional memory. Adding another Hard Drive would work, but the question states that you don't have any money to spend. Formatting the Hard Drive deletes everything, so you will have more space, but everything you have now will be lost. Compressing the drive makes what you have on the drive now fit into less space, so you can fit more.
