I didn't know if this should go here or in the Driver forum. I've been getting different blue screens pretty steady now for the past month. MEMORY_MANAGEMENT PFN_LIST_CORRUPT PAGE_FAULT_IN_NONPAGED_AREA IRQL_NOT_LESS_OR_EQUAL I ran that verifier.exe and pinpointed it to "ntkrnlpa.exe". Whenever I had that checked and restarted I would get the blue screen: ***STOP: 0x000000CD (0x89F13000, 0x00000000, 0x8053696F, 0x00000000) So then I'd have to boot up in safe mode, Run verifier.exe /reset and restart normally to not get the blue screen. How do I fix this? I know "ntkrnlpa.exe" is in my system32 folder and that it's "NT Kernel & System" and 1.96MB in size. Is this what is causing all my blue screens? What do I do now? BTW, I don't have any spyware (ran Spybot, Ad-Aware, etc all the time), viruses (ran Norton and Trend Micro), and I'm pretty confident that it isn't bad RAM (ran Memtest for 10hrs with 0 errors). If you need anymore information let me know.

check for bad sectors on HDD: How to Perform Disk Error Checking in Windows XP A file may be in a bad sector. --------------- Then Try System File Checker: Open the Command Prompt, then type: sfc /scannow note space between the c and / Have XP CD in your drive. Information about SFC ---------------- Memory(RAM), test program for downloading: http://www.memtest86.com/

I forgot to mention that I ran check disk without any problems. I already ran that memtest with 0 errors. That's the exact site I got it from. Here's what I got if that's of any use: ---------------------- Memtest-86 v3.2 AMD Athlon 64 2210 Mhz L1 Cache: 128 18114 MB/s L2 Cache: 1024k 4500 MB/s Memory: 2048M 1762 MB/s Chipset: blank Walltime - 10:00:00 Cached - 2048M RsvdMem - 276M MemMap - e820 -Std Cache - on ECC - off Test - Std Pass - 16 Errors - 0 ECC Errs - blank ---------------------- I can't do that File System Checker since my XP CD isn't handy at the moment. I absolutely need the CD in order to run that?

If SFC needed to replace a file, then the CD is needed. I guess that you may be able to run it just to see what if finds, without the CD, not sure. The SFC link above states- If System File Checker discovers that a protected file has been overwritten, it retrieves the correct version of the file from the cache folder (%Systemroot%\System32\Dllcache) or the Windows installation source files, and then replaces the incorrect file.

Yeah I definitely need the XP CD. Should that fix my problem my replacing/fixing the ntkrnlpa.exe file?

Not sure, I am not too knowledgable, just giving suggestions to try. Like I said, you could try SFC without the CD, to see what it finds. You can find all of your errors here-- KNOWLEDGE BASE LINKS STOP MESSAGES And the thing to do would be to find a common factor in all of the errors.
