I was trying to fix a Toshiba A50 laptop running XP Home SP2. The laptop was experiencing frequent blue screen failures, with the IRQL_NOT_LESS_OR_EQUAL and STOP: 0x000000D1 messages.

I followed the instructions in the malware and spyware cleaning guide, but the problems still occured. It reached the stage where the laptop would only boot in Safe Mode.

I do not have the original XP installation disks, however i do have an XP Pro disk, which i inserted while in safe mode. This asked me to a) Upgrade or b) Re-install. I chose a), assuming, i guess, that that might fix the problem without resorting to a full-blown re-install. That has unfortunately made a bad siuation worse. The setup went so far, then re-booted the laptop. The computer now crashes with the same errors regardless of whether i'm in safe mode or not.

I'd appreciate if someone can advise me on a course of action

download the following file: rc.iso....from here..then run chkdsk /r... from the cd...be sure the bios is set to boot from the cd drive first...

go here and get burncdcc ..a small FAST no frills iso burning program...

NOTE...do not put a blank cd in until burncdcc opens the tray for you
1. Start BurnCDCC by clicking on BurnCDCC.exe
2. Browse to the ISO file you want to burn on cd/dvd ....in this case its rc.iso
3. Select the ISO file
4. click on Start

make sure in the bios the cd drive is the first boot device....put the cd in the cd drive..boot your computer....when you get to the screen that gives you the option to install or repair ...select r...then when you get to the prompt...type in chkdsk /r..press enter

NOTE THE SINGLE SPACE BEFORE THE /
While chkdsk is running you will see a light blue window with a dark blue band at the top and bottom. or a black dos box depending on on which cd you use... a Chkdsk will display the specific stage it is checking as well as the percentage of completion of the stage....
there are 5 stages...it may appear to hang at a certain % for a hour or more...it even will sometimes go back over a area...this is normal...
DO NOT SHUT DOWN THE COMPUTER OR YOU CAN HAVE SERIOUS PROBLEMS...it can take a long time depending on how large the drive is...
You cannot do anything else on your computer while chkdsk is running. When chkdsk is finished, it will automatically reboot your computer....

when your done running chkdsk /r...try repairing windows...

Thanks for the reply happyrock. Prior to getting the reply i made some progress - i got to the Bios and set it to boot from CD so i was able to use the XP disk to cancel the upgrade and do a fresh install.

Everything seemed fine, except when i went to reload the drivers, wireless first (i had saved them when i was previously in safe mode). Guess what, i got the blue screen of death again. I therefore went back to previous configuration that worked, i.e. the vanilla XP re-install, and will try to source the drivers from the net instead.

Thanks for your help

go here Toshiba support to get your drivers...grab them all while your there...burn them to a cd...just in case sometime in the future you need to reinstall a driver you will have them on hand...
check the device manager for any yellow ! or ? marks...
always start with your chipset driver..that will fix a lot of issues
