Hello.. I hear many have this same problem.. but mines a little more odd... here's the story, computer was running perfectly fine after purchase for a year or so, then it starts acting a little strange, really slow even though I've got a decent amount of memory, awesome video card, etc. so I reformat.. and oh after I reformat all hell breaks loose on my E: drive, won't recognize disks AT ALL, so assuming something went wrong in the formatting process, I format again, this fixes some of the errors, some disks are recognized not others (mainly games will work) so I uninstall and reinstall the drivers for my E: drive, and now most games and some DVDs are recognized instantly, others after several tries, and then there's other disks that won't be recognized at all one day, and then recognized the next. It's almost as if my E: Drive is choosing what it wants to play... I know the drive isn't screwed, the disk spins, the lights comes on etc I even had my computer professionally cleaned about 3-4 months ago.. is there any way to fix this without getting to the inner workings on my computer? Such as switching plugs, and all that fun stuff. If it comes down to that, I'll leave it up to the pro's but I don't want to pay 40$ to have some guy install a simple program on my computer.. if you know what I mean...I'd rather know if I can do it myself.. please help, I am very frustrated after three days of a constant battle with this thing. Thanks in advance.
