Hi all, Ive had my laptop for a couple of years now, its a acer aspire 5630 and up until about 5 days ago it had xp media center edition installed on it and I never had any problems with the hardware. But as I said about 5 days ago I installed vista ultimate x64 (a clean install). And everythings fine except for the fact that yesterday i ran my antispyware and usually on the startup screen i can also include the dvd drive and external drives (i presume thats the same with all of them), but yesterday I only had the option of checking my C drive the dvd drive wasn't shown. So I clcked on my computer and I couldn't see it there either (started to panic) looked in disk management and its not there, bearing in mind it was very late last night I quickly went on google and found a few other people had a problem with they're pc not recognising they're dvd drive, and someone had posted a reply saying to go into regedit giving the name of the file and then looking in the box on the right for upper case files and lower case files, deleting them, and reboot your computer. I don't even have those 2 files in the corresponding folder in regedit. I even put a disc in hoping that it'll start to turn and i'll have a popup saying new hardware found. I even downloaded driver detective so that it'll give me a report about it and the model number, driver detective says TSST DVD/W TS-632D ATA is unplugged. Please does anyone know how or why and how I can fix this problem. Thanks in advance.
