cd tray ejects automatically

[yrana2002]

I have an acer 4520 aspiron laptop with DVD/CD combo drive...
Lately ive discovered that my cd tray ejects on its own for some reason, very randomly at any time...

Its not like its related to any particular program or anything.. and i cant figure out the reason for it

Check for the presence for any alien programs.

Otherwise, it's a hardware failure.
