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:
MSI MS-10342B-035 (M660) Core™ 2 Duo Notebook Barebone, Socket M, Intel® 945GM, 15.4" WXGA TFT Glossy, SATA, DVD±RW, Webcam, Integrated Intel® GMA 950 Graphics
Mfg. Part No. 10342B-035
Item Code. NBB-MSI-10342B035
a factory reset is fine
I have no recovery disk, nor do I have a second computer running Windows 7 in my home, nor do I have any CDs of Windows 7. I do have the license key that came with the laptop, however
I did what you said. What I get is "Windows boot manager". It says: "choose an operating system to start, or press tab to select a tool"
the only operating system available to choose is Windows 7. The only tool available to choose is Windows memory diagnostic. What do I do now? It also gives me the ability to specify an advanced option by pressing F8
I did so. I can choose from: repair your computer, safe mode,safe mode with networking, safe mode with command prompt, enable boot logging, enable low resolution video, last known good configuration, directory services restore mode, debugging mode, disable automatic restart on system failure, disabled drivers signature enforcement, start Windows normally
I will do so but I tried it before and it didn't work because it asked me for a password XXXXX I didn't have
I tried. I am seeing on the screen now the words "Starting Windows" The Windows logo is flashing, telling me to wait. it's about 3 minutes now that the laptop is stuck in this state. When something happens, I will let you know. Thank you.
it's been 15 minutes now and nothing has changed. The good part is that the computer does not seem stuck, since the Windows logo is still in motion. How much longer should I wait with this to see if it gets us anywhere?
I told it to try to repair the computer. It is giving me 2 options for user names. For each one, it is asking me for the password. I have no idea what passwords to type for either of them.
The choices I am given are:
I'm pretty sure that the second one above, MSI, is what the technician who repaired the computer set up for me.
it will not repair the system unless I give it the password XXXXX one of these usernames
it doesn't work for me. When I press and hold the F3 key, I don't get the system recovery screen. I just get what I told you earlier: the Windows Boot Manager
I tried that too. Same effect. I still get "Windows boot manager".
It says: "choose an operating system to start, or press tab to select a tool". It also lets me press F8 for advanced options, but when I do F8, none of the advanced options are "system recovery"
do you mean I should turn off the computer, and try all those keys as it boots up?
I tried F11 as you suggested. I received a screen asking me to select my boot device. The choices given me are: my hard drive, my DVD drive, and "Network". The last choice surprised me, since I didn't expect to be able to boot from the "network". It says Network: Realtek Boot Agent. Should I try a different F key or should I pursue something from this screen?
I have gone through all of the F keys except for F6 and F7.
I will let you know after I test those 2 keys.
I am writing to you now because something interesting happened when I pressed F10. it gave me the ability to edit the command
it also let me edit the path that Windows uses to boot from. Is there anything to do on this screen, or should I continue with my remaining 2 options, F6 and F7?
I did the other two keys, and got nothing special.
(By the way, nearly all of the F Keys gave me the same screen that the F3 screen gave me)
Now what am I supposed to do?
Assuming I had a Windows 7 installation disk, how would I use it?
I assume I would just go into the BIOS and tell the laptop to boot from the CD drive first, before it boots from the hard drive. (And of course I would put the disk into the CD drive before doing so) --- but what about the Windows 7 license key? Would I have to purchase a new license key for Windows 7? I already have a license key, the one that came with the laptop.
I have a feeling that if I use someone else's Windows CD, the CD would allow me to enter the license key I already have, so I'd be OK. Is this correct?
If so, it means that all I really have to do is just get a copy of any Windows 7 installation CD (I assume that such a thing cannot just be downloaded from the Internet).
(I also assume that if I reinstall Windows, the data in my hard drive will not be wiped out. Is this correct?)
