Hey guys,

Thanks for taking the time to read my post. I had a dual partition hard drive running windows XP x64 on one partition and Win7 x64 on the other side. The windows 7 side stopped booting and was getting stuck loading in the ClassPNP.sys driver. The XP side was freezing a lot too, so I decided to completely reformat my hard drive into one partition and use only the Win7 x64 side. Since then the problem has not stopped. It is freezing up a lot, usually whenever I'm opening up Firefox or when I'm opening up an explorer windows (such as My Computer or some folder). It stops responding and if it allows me to ctrl alt del (which sometimes it doesn't) it goes to a black screen and nothing ever happens. Its causing me to have to hold the power button a lot until it restarts. I hope someone has SOME idea on how to fix my problem!! I use my computer a lot for my profession and frequent freeze ups can cost me hours of work. Thanks again! Here are my specs:

Dell Precision M6500 Laptop
Windows 7 Ultimate x64
Intel® Core™ i7 CPU Q 720 @ 1.60 GHz 1.60 GHz
8.00 GB RAM
TOSHIBA MK3256GSYF Disk drive
NVIDIA Quadro FX 2800M Video Card

I'm a bit new to trying to address problems like this, so any advice or maybe hardware diagnostic tool suggestions would be greatly appreciated. Let me know if I didn't give you the appropriate specs.

Also, if it is of any help, disk defragmenter always seems to cause the system to crash. Just something I noticed. Is there possibly a more advanced disk defragmenter that I could run that wouldn't cause the system to crash? Thanks again in advance!

Also if you at the desktop try a advance command prompt and run this command on windows 7 sfc /scannow in Windows 7 and than run chkdsk C: /r that switch /r will recover any file block corruption and will tell you to that a reboot is schedule for the disk. This command with this switch will take hours depending on your specs.

Defraggler is a third party tool for disk fragmentation. http://www.piriform.com/defraggler it has both 32/64 bits run the Defragglerx64 one run the long one

Hello, first of all thank you so much for the reply. I tried all of the recommendations with no success. I did however get an error afterwards that said "Display driver NVIDIA yada yada has recovered from an unexpected error". The screen went temporarily black and came back up almost instantly with this message. I have all the latest drivers, but I just thought I'd throw that out there just in case it is indicative of another problem. Let me know if anyone else has any software suggestions or diagnostics in general that may help. Thanks!

You can try to reinstall your Graphic driver there is a option to remove and replace your graphic drivers

did you have any problems running the sfc tool did you have any errors running that tool.

Chris,

No problems running any of the tools. I reinstalled the driver and I haven't had any problems since then so far. It is a bit early to say that it is completely resolved, but it definitely is a lot better. Thanks for your help, it is greatly appreciated.

Hey again,

Well, my machine has definitely gotten better (as in I don't have a 50% chance of it crashing when I open up firefox or My Computer) but it is still freezing and crashing a lot. I know that it is normal to have programs stop responding from time to time, but I can NEVER use ctrl alt del to resolve an issue. I get a prompt that it has stopped responding and if I try to stop the program it just doesn't work. Ctrl alt del pulls up nothing. Now it is mainly happening when I'm doing two things at once (e.g. pulling data over from an external harddrive and opening up firefox). Any ideas?

Thanks again!
