That would be a problem for e-machine. The beeps are codes.
I will try to help, but it is hard to diagnose without looking at it.
You can try several things. Open it up and make sure that everything is seated inside. Make sure the memory is pushed in all the way. Memory will beep like that when it is bad or not in.
Make sure everything is plugged up and the keyboard is not getting a key stuck.
Better yet...... If you just bought it...Pack it up and take it back to the store. You should not have to work on a new computer. The bad thing is that some stores only have a 30 day return policy. You mentioned that you have the same problem. Is this your second computer with this problem?
If you want more help you will have to give us the model number. That is a BIOS code and without knowing what BIOS is in it, it is hard to know the answer.
Don't give me a bad rating for trying to help, because this is hard to diagnose. You might want to call E-machine, because that should be under warranty and if you break something the warranty is gone. Hang on...E-machine was bought out by Gateway wasn't it? The last time I ordered a disk for an E-machine, the disk came from Gateway. In my research I found the following information.
E-MACHINE has a support siteClick her for support.
Click on the link below to read about Gateway buying E-machine in 2004.
