Today my daughter used her laptop to watch a movie online. She used the Chrome browser to watch the movie. Her laptop runs Windows 7. Her movie got stuck, and the laptop made a loud beep for 2 or 3 minutes. My daughter lost patience and, instead of pressing Alt F4 to close Chrome, she pressed the on-off button to turn off the laptop totally. Since then, the laptop will not boot, not even in safe mode. When I try to boot it up into safe mode, it gets stuck at classpnp.sys Please help.
From my research on the Internet, I understood that getting stuck at classpnp is usually a hardware error. The laptop was bought used, so it may be that this is the problem. But the fact that the problem happened right after my daughter did what she did, makes me suspect the problem is software related. I just want to add that there are no peripherals attached to the laptop at all when I tried to boot it into safe mode, nor were there any peripherals attached to it while my daughter was running it.
In case it matters, here is the spec of the laptop:
