I have recently had to reboot my whole PC and when downloading some programs, like IMGburn, nro etc DVD shrink,
Sounds like a CD-/DVD creator-cocktail of the worse kind. All the told programs are used for writing CDs and DVDs. One program should be enough or do you want to open a new company for creating CDs / DVDs? So...

... these programs keep telling me I have no device present.

I did try the Dr web stuff, this worked and all seemed fine. One I switched my PC off at the mains etc and when I loaded up, the exact thing happend, no devices present or no CD rom drives found.....Can you help....
..this doesn't make me wonder. Kay, lets try this:
1. Please check if you can find the missed drive at the Device Manager at CD/DVD drives. What does it tell you? Any yellow triangle warnings?
2. If it's not listed there
Scan for new hardware. Whats the status after doing so?
If nothing helps:
3. Uninstall all mentioned CD / DVD writing prorams please, clean up the registry with f.e. CCleaner. Does the drive appear after a reboot?
Tell us about the result after, ok?
Have a great day and good luck.
