I don't know how to explain it, but I think I ruined my computer (or a component in my computer) by BURNING A CD. I'm trying to troubleshoot what's wrong... I'll give as much detail as I can and hopefully you all can help me figure this mess out
I was listening to music through Frostwire and burning an ISO to a CD-RW through Nero 7. Suddenly everything locked up completely (couldn't move mouse, time in taskbar didn't change, couldn't ctrl+alt+delete) and the sound coming out of the speaker was just a fraction of a second of the song repeating over and over again like a broken record. As frustrating as it was to have that RW now corrupted, I figured I'd restart the computer and wipe the disc and reburn it. I hit the restart button on the case, I get past the BIOS and such. I get to a black screen with nothing but a cursor in the middle. I can't move the cursor... it's locked up again. I reboot. This time I at least get to my desktop and the taskbar loads, but again I can't move the mouse... and ARGH, it has locked up again - the keyboard does nothing and the LED on my computer isn't doing anything anymore. I try yet another reboot, and every time since then I cannot get past
this screen without the loading bar freezing during the loading proces.
So I try a few new things. I try starting it in safe mode. It loads most of the drivers... and somewhere during that it locks up and never gets out of DOS. I try running a test on my RAM with an Ubuntu disc at this point to see if my RAM is shot (as suspected, it's flawless). I try Ubuntu through a live CD. It too locks up just like XP at the exact same point (the OS loading screen).
So I've come to the conclusion that my processor is toast. I must have overloaded it when I was listening to music and burning a disc  
I don't know, can anyone offer their thoughts?
