I had to do this for vista. The problem was exactly the same then. I am now running windows 7 home premium 32bit. I get from pushing the power button till a black screen with a cursor on it.
Then it starts all over again. I'm not sure what else to do. I do not have install discs for either vista or windows 7. The shop in new zealand where i brought it from says we do not need them. Besides above suggestions, please also try the following steps to troubleshoot the issue. Temporarily disable all unnecessary hardware devices in Device Manager, such as Modem, sound card or external device.
For detail steps, we can refer to the link below:. Device Clean Boot. If the issue persists, I suggest you insert the Windows 7 installation disk and repair the system. I started to have this problem after windows 7 safe mode boot stops at classpnp.sys free download the Sniper Ghost Warrior game. Into BIOS, reseted all configs to default. Than, reboot and, inside the BIOS againreset system to your old configs.
I'm having some problems with my main HDD. HD Tune pro accuses it of having a very high spin number. A little late but I just wanted to point out that Limbix's solution worked for me. Now, I never created recovery disks.
My computer would just hang on the startup. Then I would get the blue screen of death. It will restart and then give me the option to repair or start normally.
I would choose repair. Attempted restore. Initially it would work. But as days went by, it would not restore at all. It would just reboot continously. I tried booting in safe mode and the system would hang at the Classpnp. I applied the solution provided above to renaming the classpnp. Restarted and then the system would hang at the strtup, a brief BLOD would show and the computer would restart. So the bad thing was that I never backed-up my data. Low and behold, the reccovery screen showed up.
I was able to see my C: drive. I backed-up my data. After four DVD worth of backed-up data, the computer restarted. This time, I chose restore computer to factory setting. The computer restored back to the Old Vista Home premium Originally it was bought with Vista with a free windows 7 upgrade sent later.
I did this last night, and I am currently writing this post from the same laptop. Basically, I got my laptop back. I am still unsure what caused the problem. A friend of mine said that perhaps a windows update caused the crash. I do not know. A very good lesson has been learned. I will create recovery disks that Sony offers and put them away in case I run into a similar situation in the future. I am having the same issue. I have only had the laptop since January.
It is the first time this happened. I updated Windows 7 and then it stopped. Everything I have been told hasn't worked. I had tried all the solutions posted here with no luck, as well as a myriad of other suggested solutions. Hi, I had the same issue yesterday with my pc after loading fail-safe bios settings OC gone wrong.
Solved for me. I had the same problem. If I rebooted the computer in safe mode it hangs, if I reboot in safe mode with command prompt it hangs. Anything I do it hangs.
I noticed that when windows would load files and freeze at classpnp. Then if I pressed a key on the keyboard the keyboard lights would turn back on. I disconnected my USB keyboard and rebooted I plugged the keyboard back in windows 7 safe mode boot stops at classpnp.sys free download a successful reboot. I have since restored my hard drive to an image that was backed up when I did a clean install.
If it freezes at classpnp. Disconnect all hardware that is plugged in any ports not internal to the case and start from there. Then it is process of elimination like removing ram sticks, video cards, PCI cards, extra hard drives etc What makes the most sense is that sometimes windows can get windows 7 safe mode boot stops at classpnp.sys free download in regards to allocating resources that all the hardware installed on your computer requires and can mix it up at times IRQs, etc Same problem.
Turned out to be an SDHC card. I suppose any recently added hardware can be suspect. I've just had this with an Acer, System restore etc didnt help but the problem did occur shortly after a windows update. I removed a wireless card from the system that wasnt in use and it booted straight up. Alright I have a dell xps and today I ran Windows Update. My PC no longer boots into windows.
I've tried safe mode and it stops at classpnp. I have tested this solution. It does crash your computer. This Classpnp. There are no definitive solutions to it. My netbook doesn't allow me to try the BIOS solutions mentioned. I am still in the process of chkdsk and later on sfw, but sfw didn't work for me with the commands posted in this thread, i searched around a bit and i found this:.
Right, I battled long and hard witgh this one and found it to be quiet simple if you hold your nerve. I waited almost 45 minutes with a black screen and a hyper active hard drive but hey presto it worked. As a precaution I ran an in-depth stress test to make sure nothing was indeed failing and I was lucky. Running laptop using an iso file of Linux Xubuntu on CD windows 7 safe mode boot stops at classpnp.sys free download laptop is running perfectly, so I don't think its a hardware issue in this case.
Wondering if when Win 8 comes out upgrading may fix this so I don't have to reformat my entire hard drive as above have seen reformatting has resulted in same error and reinstall everything AI got the same problem on my Windows 7 safe mode boot stops at classpnp.sys free download Z workstation.
That problem was occur after a BIOS default setting application. It was solved the problem. As it turns out, you're all windows 7 safe mode boot stops at classpnp.sys free download to find that something different is wrong with each of your computers. SYS is the offender. For me, it turned out that I had a hard drive on my secondary Marvell controller that would act up. All I had to do was remove power from that drive and my computer booted fine. Subsequently after booting into Windows I could then turn the key on the pull out drive tray which reapplies power to the drive and I have access to the drive.
I am going to check now for driver updates from Marvell that I may have missed. I stumbled across the hard drive issue because I didn't want my c: drive to become the f: when I ran a recovery with multiple drives installed. And one reboot before I was to run the recovery, my computer started working again, consistently I can recreate the error by having that drive powered during the boot process and it locks up every time at CLASSPNP.
So start removing hardware one at a time includes memory modules untill you get a good boot. Then put all the hardware back in powered off of course except the last item you had removed before the computer started acting normal, again. I took my USB mouse out from my laptop, fixed this problem. I do not know why Win 7 stack at USB connection.
