Blue Screen of Death during Avast scan in boot mode

I have used avast home edition for almost five years. Great program, no problems until possibly now. I have Windows XP SP3. And I usually do a boot scan with avast once a week. However, since December 3, 2008, everytime I thorough scan with avast inside boot mode, it progresses but before it ends around 50% the computer crashes and I get a Blue Screen of Death. The BSOD has the following:

kernel_stack_inpage_error

*** Stop: 0x00000077
0xC000009C
0xC000009c
0x00000000
0x010FE000

Yet, I have had no virus alerts or infections for over a year. However, I am able to do a thorough scan in Regular Mode. There is no notice of infection. I do not think it is infected, but I have no idea why this is happening. I am computer illiterate. This is my only computer, and I cannot afford another one at this time. Help is greatly appreciated.

The report file is created automatically in \Data\Report\aswBoot.txt. Does it have more info?
Also, it will be good if you run a chkdsk /R command and check your disk against physical errors.

Thank you for such quick responding.
Here is the text:

Scan of all local drives

Number of searched folders: 7870
Number of tested files: 96178
Number of infected files: 0

I did do chkdsk /R yesterday after finding this happen, but it still continued. Also, I can find information on all of the 0x…etc, but no info on 0x010FE000. What is 0x010FE000. Still needed help with the original problem, but another thank you.

Please run a diskcheck on your system drive, including a surface test.
It sounds like a bad block on the disk to me (though I may be wrong, of course).

ahhnoo, how much RAM does your system have?
This blue screen can sometimes occur in an out-of-memory condition.

Thanks

I just posted this morning, and already getting help within minutes. Continuing thanks. I did a diskcheck repair (chkdsk /r) it repaired some things, and I will try a boot mode scan to see if it was fixed. But in case that didn’t work what and how do I do:

Surface test?
Check how much RAM?

Also, what does 0x010FE000 mean? I know the others, but not that one.

Again, thank you for the continuing help.

As far I know, the /R parameter should do it. Am I wrong? ???

Start Menu > Control Panel > System > The OS installed, the processor information and the amount of RAM will be displayed.

This is a list of all the switches.

Good news: The computer has been saved. Yesterday afternoon, I chkdsk /r and after went into boot mode for avast thorough scan. The computer was corrected, and I had no problems with the scan. I even did another boot mode scan after the first, to make sure. No infections were present. Thanks all for such great wonderful help. If I ever become better computer literate, I’ll be sure to try to help with any others’ computer problems in this forum.

My only question remaining, is what caused the problem? I understand the BSOD, but what caused my computer to be like that for a time, and then was corrected. What was corrected?

Power down and power failures could do to file system problems and errors. That command correct them :wink:

Actually, BSOD status code 0xC0000009C indicated bad sectors on the hard disk.
Problem solved.
