Hi Recently I've installed two different burning softwares in my computer, DVD Cloner Platinum, and Roxio Easy Media Creator, respectively. I wanted to burn a bootable .ISO image into a DVD-R, but since DVD Cloner doesn't have such functionality I only used Roxio Easy Media Creator. On my first attempt, I clicked on "Burn from disc image" button to burn the .ISO into the DVD properly. Thing is, it's supposed to be a boot OS .ISO file, so I'm not sure if I had to add boot properties to it or not. Anyway, I only chose to burn from disc image and the process went just fine, however once finished the DVD showed no contents at all. Assuming I had gone through the process the wrong way or that something went wrong in the burning process, even though it didn't show any errors at all, I tried again, this time simply dragging the .ISO file to another recordable DVD. Obviously it merely just copied the .ISO file into the DVD which isn't the way I wanted, but once again the burning process went flawlessly, and this time when I go to my computer and double clicked the DVD to see it's content, I could actually see the .ISO file in there. So, I switched back to the previous burned DVD, this time it actually read it properly and behaved as if it was the actual OS disk. I proceeded to restart computer, set up the booting order accordingly to install the OS within, but whenever it got to the "Boot from disk" part it would skip straight through to booting from hard drive as if there was no DVD present. I restarted and retried it several times, and once, I was spamming random keys very quickly dring the boot from disc part and it actually booted from the DVD but also unfortunately selected a bunch of options I couldn't see by accident due to my rapid key spamming, so I had to restart the computer to try again and it never recognized the DVD again. On top of that my computer had been behaving strangely, sometimes turning off immediately a few seconds after restarting and sometimes it would not restart at all. I later found out that some of the cables inside it had come a bit loose which seemed to be causing that, but I'll admit the whole incident had me lose my temper and I ended up banging on my computer's casing a couple of times next to the DVD-reader on a spot with no hardware or cables underneath, but not directly on the reader, not with much force and not while the DVD reader was actually doing anything, either. Now, the reader already seemed to have been faulty, not recognizing DVDs after burning those two DVDs (had been working just fine before that, though), but still I'm worried that it may have broken the DVD reader, because I've ran windows "Fix It" tool after my internet came back (hell of a day, nothing's been working properly) and it said it found a problem on the DVD reader but couldn't actually fix it. I also went to the registry and deleted lower and higher filter entries but it still can't read anything. I'm running Windows XP, the system still recognizes the DVD drive being there, the drivers are fine and I get no error message when trying to see the contents of a DVD inside the drive, the LED lights even go up for a short time and I get the "reading disc" mouse cursor for a little while after loading a DVD in, but it just won't read them. TL;DR: DVD reader stopped reading DVDs after burning a couple of DVDs after installing two different burning software, lost my temper and banged on my PC's casing next to it, but not directly on top, not very hard and not while it was functioning. So how can I tell if the drive is actually broken, or if its' just some software issue? Also, if it's just a software issue, how do I fix it?
