Laptop will not connect

Posted on 2009-02-16

Around 7 days ago my Dell laptop 'blue screened' about 4 times. Its automatic disk check came up with a few corrupted files and then it stabilised itself.  At first I thought the hard disk was giving up (the motherboard was replaced about a month ago) but it hasn't crashed since.
Since then it :1 Numerous "the application failed to initialize properly (0xc0000142)" errors on startup
2 Hangs on certain tasks. eg. extracting Windows debug symbol file, defragmenting
3 Will not connect to internet either over wireless or network card
4 Will not connected to Aventail VPN 'Access denied' message
5  tells me that my user account does not have admin rights even though it is listed correctly under User accounts.  I had to use the local (no domain) 'Operations' account to run windbg and regcure

I have :
1 Disbabled and removed 'Integrity client' firewall software
2 Decrypted hard disk (It was encrypted with Encyption Plus)
3 Clean-up hard disk
4 Run a full disk check
5 Run a full virus scan using NAV
6 Run Regcure to remove any corrupt registry entries
7 Run Malwarebytes
8 Run windbg on mindump files .. original crash caused by pwd_2k.sys
9 Examined event log .. lots of error 481/485/489 "an attempt to delete c:\windows\softwaredistribution\datastore\logs\edbtmp.log failed" I don't use Exchange !!

Please help .. I am having to lug round a desktop and a flat screen until I can fix this !!

    re-seat the memory in the computer.
    I would also try to do hardware diagnostic scans - memory and hard drive - to see if any fail.  if they fail, replace the parts.  A pass doesn't mean that it might not be having problems.

    I would also consider doing a repair install of XP (not from the command line).

    1. Download all updated driver from Dell web site again
    2. reinstall windows with the latest drivers

    I have many experience that the stock driver of Dell machines are too old to run stable.

    Accepted Solution

    The hard disk was replaced after ghosting the contents.  No need to re-insatll all my apps !!
    All the problems I mentioed above were solved.  
    I suspect it was some low level disk corruption.
