Power Supply Problem?

I just found that my LiteOn SOHW 1693S isn’t being recognized by Windows XP Pro, SP2. Device Manager tells me that the drivers are loaded, but it can’t locate the hardware. If I uninstall it, XP does find it on the next powerup (found new Liteon drive, new CDROM drive, etc.) but when I go to Explorer, it’s not there. I did put the drive in in another XP PC & it’s fine. Is this the kind of thing that is typically caused by a weak power supply?

if your in any dout about your power supply, then change it.

i have just changed my 2 1/2 yr old power supply and my 1673s is burning a lot better and my aopen dvd-rom has stopped locking up my system.
