    Hi,
    For the past year or so I've been getting BSODs with the stop code 0x7a (kernal data inpage error).

    Last week my wireless Internet stopped working on my computer, even though it continued to work on all other devices in the household. It showed as connected on my computer, but I would get a dns/connection error every time I would try to go on a web page or use a program that needs Internet. It would sometimes work for a few seconds then fail again.

    This morning, I noticed my computer was lagging and after a while things began to freeze up. I knew from past experience that a BSOD was coming and sure enough I got one after an hour.

    Usually when I get BSODs I can turn my computer off for a while and then reboot with no problems, however this time it's been problem after problem. At first I could start windows normally and get to my desktop after a little while, but things would right away freeze up and I would have to shut down.

    For a while I could boot pretty well into safe mode, but things were still slower than usual.

    Right now I'm at the point where I tried to boot in safe mode but it wouldn't let me, and booted normally. When I got to my desktop, it told me "desktop is not accessible, access is denied". I'm fed up with trying to fix this myself, so any help is so so so greatly appreciated. I'm a noob when it comes to fixing this stuff so go easy on me :)

    Thankfully I backed up all my files, and I saved my minidump files to my external hard drive, so let me know if you need me to upload them. I'm using my iPod to upload this message but I can use a friends computer to upload anything you need.

    My info is:
    Windows 7 64bit
    Toshiba satellite l500d

    Thank you so much!!!

    Ok, so I tried running the DOS in safe mode, since I can't boot in normal mode, and it told me it wasn't the right version. It might just have to do with the fact I'm in safe mode. I'm not sure.

    I'm running chkdsk now, it was stuck at 11% for 10 minutes or so, and now it's saying it has replaced a bad cluster in a file. I'll post an update once chkdsk has finished.

    Oh...haha now I feel dumb...

    On another note, chkdsk is either frozen, or taking an hour to process one file. Should I restart my computer and just do the dos thing? Or should I wait?

    checking the hard drive can take hours,but chkdsk checks the file system only and usually does not take that long

    It's on stage 4/5 'verifying file data'. It seems stuck on file 178721/253424, as its been on that file for over an hour. Is there something I should do?

    Ok, chkdsk has finished. It found something like 60 'bad sectors'. I'm not sure what that means.

    I'm trying to figure out the whole DOS thing, but I honestly have no clue what that is. The text file says I need to boot from a DOS disk, which I don't know if I have. I'm not great with computers so some help would be greatly appreciated!

    So after chkdsk, I can now boot into normal mode! My wireless connection is still fishy (the wireless is fine, it's something to do on the computer's end), but at least now everything is somewhat stable.

    I too think it's time for a new drive...however I have everything backed up, so I'm basically gonna run this drive to the ground and then get a new laptop.

    Any thoughts on what problem could be causing my internet to be messed up? The connection says it's always connected, however sometimes it just won't let me connect to the DNS, or something. The troubleshooter tells me nothing.
