I recently upgrade from Windows Vista 32 bit to Windows 7 Ultimate (64 Bit). I have an HP Pavilion DV2810US (or a DV2500, theyre the same thing). Recently my cd/dvd has not been working at all! When I put in a cd or a dvd the little light on the cd drive turns on, the cd spins and NOTHING HAPPENS. I used a MYFIX IT program and it told me My optical drive isnt being detected. When I pop the cd in, I don't even see it on My Computer the E: CD Drive, and when I go to Device Manager I don't see the CD/DVD button that alot of forums online say I should play with. Any help would be greatly appreciated! Please let me know if there is a way I can see if its burnt out so I can replace it or if its just disconnected on how to connect it or if it just need an update I could do. Please help it's urgent as I need to install software for my class and it only comes in the form of cd THANK YOU!
