I have a Toshiba Tecra A1 laptop w/Windows XP and SP2.  I recently tried to download an update of Adobe Acrobat and began experiencing problems:
 1: The download stopped in the middle and restarted my computer with the following error:Kernal_Data_Inpage_Error.  I was able to restart and still access the web several times.
2: a day or 2 later my computer began shutting down spontaneously and would bring up the safe mode boot screen.  I booted in the debug mode and that option seemed to 'fix' it for a few hours.
3: a few hours later the computer began shutting down and booting to the safe mode screen in a continuous cycle (I'd choose safe mode and it would act like it was going to load, then it would go back to safe mode screen).
4: A friend of mine 'fixed' it (with his Norton recover disc) and recommended I download a registry cleaner to 'fix' my slow loading of programs.
5: I downloaded ErrorKiller, used but did not purchase (I uninstalled after I found another registry cleaner that had good marks from a consumer).  Then I downloaded AND PURCHASED MaxSecure's Registry Cleaner, which found over 2000 errors!  I deleted ALL of those errors and then my modem stopped working.  When I Queried the modem I got the following error: OpenComm, the port that the modem is attached could not be opened.  This may be the result of a hardware conflict.  Check the device manager to verify all devices are functional.

I have checked, rechecked device manager and have found NO conflicts (there are about 4 other devices that use the same IRQ, and I have tried to disable them and then use my modem but did not work).  My COM3 port doesn't even show up on my device manager ports.  It is an internal modem, so it could be a virtual port????  I have removed and reinstalled my modem several times.  I recovered the deleted entries from Registry Cleaner, I uninstalled it, rebooted the computer and STILL NO MODEM.

I'm on my desktop, so I downloaded a new driver from Toshiba.  Installed it on laptop, but no happy ending.

I tried my BIOS; I tried my msconfig; my system.msc; I even tried to recover to an earlier save but found that my previous saves are NO LONGER THERE!  They have disappeared.  So, I can't even roll back to a few weeks ago.

I've noticed that other Toshiba owners have had this SAME problem, but have found no solutions to their angst.  PLEASE, oh masters of the Computer Universe. HELP ME.  My husband threatens to divorce me if I don't put desktop back in storage (takes up too much space!)

I do have HijackThis and will try to use my wireless network at my office to access the internet and post a log (from my laptop).  but, I have not tried my wireless network since the modem problems, can't guarantee it will work.

Thank you in advance my wise men (and women).

do you have a sytem restore cd? then the easiest way out would be : backup your data, and use the system restore, to put the laptop it a "new" state.
you can try to run sfc /scannow from the run box, to check your system files, or even a repair install :

I do not have a system restore disc. (that's why my 'friend' used his Norton recovery disc last week)

I do have a Windows XP disc from my desktop, but it is Home edition and I have Professional on my laptop.

Am trying the sfc /scannow.  It's taking a LONG time (been running for 30min, so far).  If that does not work I will try downloading the repair install.  (My wireless internet still works!!!:) (But I must travel to work with my laptop to use the wireless)

Thanks for the suggestions, I'll check in with my progress.

I did have a virus, but turned out my internal modem was 'broken'.
