Dear FB, it could very well be a hardware issue, but it could also be a virus or even a microsoft update issue.
Ktreas, you can replace cards in your computer reletively easy. Unscrew the case and pop out the piece u need to replace and insert another. There are many videos on youtube which can walk you through it! Best wishes!
Dear Marilyn, I worked as a PC technician for over 10 years. I think I know what I am talking about.
1 Long, 3 Short - Conventional/Extended memory failure
You stated you had 5 gb of ram, which is an unusual number, they usually come in even numbers and come in pairs. If you know what the ram looks like, try first to see if any are not seated properly.
If that is your motherboard, the ram is located in the blue and black slots.
If they all seem to be seated properly, remove them one at a time and then try to boot it up.
Also, make sure that before you touch the motherboard, or remove the ram, or do anything, that you unplug the computer, and ground yourself by touching the metal on the case to discharge any static electricity.
