Why doesn't my disc drive work?

I have an e-machines computer and the disc drive doesnt work. I just got it fixed after it wouldnt turn on and had to spend 7 months with out it. I was wondering if I could fix it from home ?? any advice would be helpful.

thanks

Take the drive out.Check the connections.See if the power supply is right.Try interchanging the hard disc and the drive. Also try changing the cable

Floppy disk drive, CD disk drive or Hard Disk drive?

Also, not too helpful now but in the future try to avoid e-Machine computers.

lol ok I will
