I have a Dell Inspiron 3521 and it had been a year since I have used a DVD. But when suddenly I got a serious work on a DVD it errored. I just put in the DVD and wait for some time but nothing was showing up then I opened explorer and tried to open the DVD drive E:\ but nothing showed up for about 5 min and the cursor was loading and loading. I tried to put all the other CDs and DVDs I had but still the same problem. I tried to boot from a cd in bios and it worked really well. So, I thought it is a software related issue so tried it on the web. they told me to delete Intel rapid storage and the DVD driver. So, I went to device manager and tried to uninstall the DVD but whenever I tried to uninstall the device manager got hang. so I tried to delete IRST but still the same, for almost half hour the uninstaller didn't have any progress. so, I tried to go to safe mode but when I was on the lock screen in safe mode, a black screen kept blinking which didn't allow me to put in my password. And now I am here to you. Please help me with a solution.
