Hard Error message help please

[Twister00]

Has anyone ever seen this error message in WinXP before:

On a blue screen:

Stop: C0000221 Unknown Hard Error
\Systemroot\system32\ ntdll.dll

Or this one?

On a black screen:

Windows could not start because the following file is missing or corrupt
\windows\system32\config\system


This is on a new P4 2.0A with an MSI 845E Max motherboard with 512MB DDR 2100 a Maxtor 30GB 7200 HD with MSI 64MB GeForce 4 MX420 VC

I swapped memory with another stick I know the HD is working properly and did a repeat test and came back in proper working order.

Thanks in advance

Are you overclocking at all?

 

[Twister00]

Nope all normal settings.

Is there any tech support in the tech support forum

Has anyone seen this error before?

Yes, I've seen both these errors on XP, and just recently. They occured on my system while I was seeing how far I could overclock. Since you say you are not overclocking I suggest you check your memory settings. They are probably too aggressive for the memory you were trying to use. For example, try 6-3-3 instead of 5-2-2.

EDIT: Also, sometimes moving memory to a different slot can fix this problem.

Settings are at 7-3-3. Could it be a bad motherboard? Tried a different video card without error messages.
