Updating computer motherboard

Thursday, November 26th, 2009

Usually, it is no problem to update Intel motherboard for Windows XP system. For example, if you have a Windows XP installed on an Intel motherboard, if you want update it, just simply replace the old motherboard with the new one, it will work for most of case. Some need you do Second repair to fix the system to fit the new hardware. However this one, there is a little tricky inside, I write this down because it is a good experience to share.

The old system is Intel board D915GMH running Windows XP SP3, actually, the original installed OS was Windows XP without any Service Pack, it was gradually updated to SP1, Sp2 and finally SP3.

The new motherboard is Intel DP55WB, of course, the CUP and RAM are new too, they are Intel Core i7-860 and DDR3 respectively.

Now, the problems are:

  • With the new system(Intel DP55WB), it comes blue screen with 0×0000007B error: STOP: 0×0000007B(0xF741B84C,0xC0000034,0×00000000,0×00000000)
  • Second Repair does not work because the Windows XP was updated from no Service Pack to SP3, None of Windows XP install CD works (I tested Windows XP, XP SP1, XP SP2 and XP SP3).

Fortunately, Microsoft provides a solution, it works:

The blue screen has gone, however, it brings a new issue:

DP55WB does not have PS2 ports, I have to use USB keyboard and mouse, but the system can’t not pickup USB stuff automatically. So I put the hard drive into another system with PS2 ports, it is Intel DG41TY, however, there is nothing in Device Manager.

And again, Microsoft has another solution to solve this problem:

http://support.microsoft.com/default.aspx?scid=kb;en-us;311504

Then, everything goes smoothly, it picks up USB stuff and eventually, the whole system work on DP55WB system.

NOTE: when I do the test, I always use ghost to copy a backup hard drive to do so.

Remove Hijack.Windowsupdates

Wednesday, November 18th, 2009

Run Malwarebytes’ Anti-Malware  and  find

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\BITS\ImagePath (Hijack.WindowsUpdates) -> Bad: (%fystemRoot%\system32\svchost.exe -k netsvcs) Good: (%SystemRoot%\System32\svchost.exe -k netsvcs) -> Quarantined and deleted successfully.
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\wuauserv\ImagePath (Hijack.WindowsUpdates) -> Bad: (%fystemroot%\system32\svchost.exe -k netsvcs) Good: (%SystemRoot%\System32\svchost.exe -k netsvcs) -> Quarantined and deleted successfully.

It will come again even after you remove it. Some people discuss it here

By the time I write this post, it did not solve the problem. However, I find an easy way to remove it:

Delete all the Quarantine items from all anti-virus program running on the computer and it works.

Windows XP keeps rebooting

Monday, October 19th, 2009

There are many reasons of Windows XP keeps rebooting.

Usually, when windows keeps rebooting, there are some options you can choose:

  • Safe Mode
  • Safe Mode with Networking
  • Safe Mode with Command Prompt
  • Last known Good Configuration(Your most recent settings that worked)

Unfortunately, most of time none of them works, it looks like you can’t do anything with them. While windows is rebooting, you may press F8 to get more options, they are:

  • Enable Boot loggin
  • Enable VGA mode
  • Directory Service Restore Mode(Windows domain controllers only)
  • Debugging mode
  • Disable automatic restart on system failure
  • Reboot
  • Return to OS choices menu

What can you do?  Try “Disable automatic restart on system failure”, you will get some detail information.

Here is an one example:

Blue screen

UNMOUNTABLE_BOOT_VOLUME

STOP:0×000000ED(0×8A2CA9E),0xC0000006,0×00000000,0×00000000)

Microsoft has given an answer:

http://support.microsoft.com/kb/555302

Let’s try chkdsk /r

After one and half hours, computer showed message:

CHKDSK found and fixed one or more errors on the volume.

then type exit, the computer restarted.

It worked!!! So, this one can be a case of why Windows XP keeps rebooting.

TODO: Will wirte more different cases for Windows XP keeps rebooting.
