Win7. My Asus DRW24B1ST optical drive isn't reading any discs. It opens and closes fine but the drive doesn't appear in My Computer. I went to the system restore menu and it says my drive has been disconnected. I googled how to fix the problem and followed all kinds of steps and how-to's but its still not working. I don't feel like its a hardware issue since it still opens/closes fine. I installed new drivers from Asus website and have the file on my desktop but I don't know where to put it or how to update the drivers. I went into the registry and deleted upper and lower files. Don't know what else to do. Please help, thank you.
