DVD-Rom Problem

[i_am_pants]

Hi ill try to give as much info as possible here to see if anyone can help.

I recently started buying games to play online,to be precise f.e.a.r and battlefield 2142.The games will install from dvdrom fine,but when i go to play them it sems the game cannot detect my disc in the drive.

A partial workaround for fear was to open the dvd up in windows explorer and double clicking the autorun,but having just installed battle field 2142 it wont work at all.

I have a pretty clean windows install,with only ultraiso as something close to emulation software maybe causing a conflict?.
2 sata drives,and my dvd drive (pioneer 111),set up as primary ide master.

Thses are legit games with cdkeys etc and any help to whats going on would be much appreciated,the dvd drive is fine apart from this,it looks like it just wont run pc games?
