    I had been having blue screen problems with my old Dell XP. The programs WhoCrashed and BlueScreenView implicated a few drivers of non-essential software as the culprits. I examined the drivers module in AutoRuns (by Sysinternals) and carefully selected non-essential software drivers for disabling of their autostart status by unchecking the box in AutoRuns. (I avoided hardware drivers, Microsoft drivers, and drivers for actual autostart programs.) Three times when I restarted after this limited driver-autostart disabling I got the STOP: 0X0000007B blue screen. I was in effect forced to use Last Known Good Configuration on the subsequent startups, and this restored all the autostarts I had disabled. To test what was going on, I shut down my system without disabling any driver autostarts, and the system started normally.

    I tried disabling via AutoRuns only two files in the system32\drivers folders that were implicated in previous blue screens : wrkrn.sys (associated with Webroot, which after expiration had continued on my system as an on-demand scanner) and vvbackd5.sys (associated with a FarStone program which I had not yet chosen to utilize). I got the STOP: 0X0000007B blue screen again. After this in my frustration I shredded wrkrn.sys and vvbackd5.sys.

    Really bad move. After this I continually get the STOP: 0X0000007B blue screen when I try to start the computer. On the next try I will get the menu that offers "Safe Mode" and "Last Known Good Configuration", etc., but those options lead only to more STOP: 0X0000007B blue screens. I had deleted those two drivers previously without problems, but it had been after moving them out of system32\drivers. (And of course, the drivers had been recreated.)

    I know it's academic at this point, but what do you think I could have done with those drivers without creating the mess I created? Maybe I should have just uninstalled the programs although I preferred not to.

    I took my computer to one repairman, and he said it couldn't be fixed. I want more opinions.

    I have a new computer I will be setting up soon, but I had really wanted to keep this one as a second computer to use for limited purposes, including substituting if the new one has to go to the repair shop.

    I also want to recover everything off the old Dell. The repairman said he didn't think I would be able to recover my Outlook Express emails. What do you think? I could set up a virtual XP on my new computer and possibly get my Outlook Express emails that way, I think.

    The repairman said I could use an IDE to USB adaptor to drag and drop files and folders from the old Dell XP to my new computer, although he doesn't think that will work for restoring Outlook Express emails. A good adaptor of this sort can be had for as little as $20. Any advice about this procedure?

    I have Laplink PC Mover Ultimate. I called Laplink support late at night. The technician said he that in order to use Laplink PC Mover Ultimate in this situation I would have to fix my old computer first. He said he could help me do that, interestingly enough. But he said I would have to sign up for a year of iYogi support for my two computers at $299. Ouch! And that's more than double the subscription price at iYogi's own website..

    So do you think my old computer can be fixed? Any advice on any points raised here would be welcome.

    number 1: your chosen repairman sounds like an absolute idiot and is not someone i would deal with ever again if i were you. a blue stop screen error no boot doesn't really mean jack diddly squat in this field. driver errors and memory buffer overflows are common for creating many various stop screens and these are by no means indicators that the machine is not able to be fixed.

    number 2: unless something in the bios or the motherboard is fried, you do not need any cable whatsoever to get your files off the machine. if the machine will recognize a disc in the cd/dvd drive then that's all you need. unless your ram is toast and then this could be a problem. if your hard drive is fried then this won't matter but the files are still very much able to be recovered though not without a lot of know-how and not without a significant cost.

    make yourself a winpe disc, or if this is not something you can do, download one of many winpe discs available online. with this live environment you can browse whatever you want on the hard drive and move it to wherever as well, amongst many other things.

    your best options are to make a complete image of your system hard drive so that you have an exact backup of everything (and in some sort of format where you can view/extract/edit the files within without restoring--imagex works great for this), and then totally wipe that old xp install and re-install it with one of the many isos found here on the boards. just from your post i'd be willing to bet you've had that same xp install running for years and it's registry is probably all jacked up, filesystem cluttered with useless junk programs, temp files, leftover files, and all kinds of other things that make the operating system unstable to begin with. (if this doesn't apply then disregard lol)

    number 3: your outlook files are most likely on your hard drive. unless you're running on a business network or highly tuned home network, a copy of all the emails in your inbox(es) in outlook is on your computer. i can't tell you the exact location but it will be something like "C:\Documents and Settings\<Username>\Application Data\Microsoft\Outlook\profile\..." you will of course have to have hidden files visible to find the directory. the application data store is where the majority of everything all your software uses to operate and remember its settings is located in XP.

    the majority of your issues are just from not being IT savvy i believe--which isn't meant as an insult by any means. most consumers are not pc savvy at all and that's why there exists repairmen, who most often don't know anything themselves...
    also you are really running on some old, crummy hardware, and to be quite honest i'm surprised is hasn't given you more trouble than this before now.


    acquire a live environment of some kind on usb/cd/dvd whatever
    make a full backup image
    acquire a new, updated xp install iso

    0x7B is a critical boot driver error. The notebook is probably setup for AHCI & these drivers are now missing or corrupt.
    You could check in the bios if your hdd controller is set to IDE or AHCI & toggle it. Perhaps the Dell dvd can repair install...

    Intel 845 chipset is way too old to even have AHCI, LOL.

    I had similar issue with a computer w/ 7 and it turned out to be memory. Swap them out for a test with good brand like micron, samsung, hynix etc Not no-name and strange names that is not memory makers that are not actually made chips and assemble them selves. Also take your computer apart to clean and also clean up heatsink fins (from the inside and outside with compressed air, do not allow fan to spin while doing this.) paste for CPU and repapply with fresh heatsink paste.

    Cheers, wizardbios

    If you have an oem xp disk or know somebody that does, you can do a repair install on XP to restore the files that you deleted, and you should still be able to retain your software
    Not enough posts to do a url yet but you can google
