Ok i have quite a problem. I have the following optical drives: 16x LG DVD-ROM, 16x Sony Dual Layer Dvd-/+rW. For a reason that i cannot figure out, the autoplay feature on both the drives doesn't work. I've re-installed Windows XP Professional countless times, and after some time has passed after the installation, i keep having the same problem. I have had my computer for 2 years now, and i bought the Sony dvd burner in December,2004 for $100 CAN. I installed it and it worked fine with my XP, untill for some reason, a couple of weeks later, when i opened "My Computer", the Dvd-rom and Dvd-burner drives were gone from there! It only showed the floppy drive! Luckily i had made a backup of my files 2 days before so i was safe. Because my computer didnt see those drives were there. I re-installed XP and after a while, the AutoRun feature was gone! I kept reinstalling...Now the last time i installed xp was late december. The same problem. For example: i put in a Half-Life 2 cd and it doesnt AutoRun it! no matter what drive! I have to go to "My computer" and there for the dvd drive all it shows is the dvd drive! no Half life 2 logo! But when i double click the drive it opens up the contents of the cd and i can install it from there. The same is for any cd i put in. I tried countless games, programs. PLEASE HELP! WHAT IS THE PROBLEM? Half Life 2 kicks ass

TRy this. Create a Restore point and back up the registry.Open regedit. Look for; HKEY_LOCAL_MACHINE\system\CurrentControlSet\SetControlClass. Key name: {4D36E965-E325-11CE-BFC1-08002BE10318} Value Data:[Delete all value data from upper and lower filters] Note-Do not delete the key or the multi-string values. Delete only the data values. Exit regedit and reboot.

i'd rather contact microsoft tech support. Half Life 2 kicks ass
