is this computer one you built or bought? how old is it? if it is one you built and its not that old try pulling the cover off and make sure the cables are connected correctly the IDE cable will have a red stripe showing pin one on it. the red stripe should be pointed to the power plug on the drive. also make sure the jumpers are set correctly and that no other cables have come off.
I have a very annoying problem. My CDR drive keeps opening and closing for no apparent reason. Since I don't know what causes it, I don't know how to fix it.
This is the first time I have had a chance to reply. Possible causes:
Software -- under what circumstances does this happen? Are you on the internet, is there a particular program running, does it happen at turn-on or if the unit has been running for a while, etc.
Hardware -- a common problem is a bad tray open/close push-button switch. The switch behind the front panel button is very cheap and prone to problems. The "springiness" to the action is provided by the same piece that closes the circuit. A partial collapse of the contact will cause the switch to intermittently short out, making it act like the button has been pressed. How does the button feel when you press it? There should be a slight-but-noticeable "snap" or "click" to the feel of it. These switches are cheap and relatively easy to replace. Sometimes, too the plastic button binds in the panel and never fully pops back out when pressed -- try wiggling it by probing its edge with a round toothpick to check this.
I have a problem with my CD drive, as soon as I start up my computer the drive opens and remains open until the computer is switched off. I have scanned the computer with anti virus, Adaware and Spybot without any solution. Can you help??
