			<content:encoded><![CDATA[<p>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 <strong>Second repair</strong> 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.</p>
<p>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.</p>
<p>The new motherboard is Intel DP55WB, of course, the CUP and RAM are new too, they are Intel Core i7-860 and DDR3 respectively.</p>
<p>Now, the problems are:</p>
<ul>
<blockquote>
<li>With the new system(Intel DP55WB), it comes blue screen with 0&#215;0000007B error: STOP: 0&#215;0000007B(0xF741B84C,0xC0000034,0&#215;00000000,0&#215;00000000)</li>
<li>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).</li>
</blockquote>
</ul>
<p>Fortunately, Microsoft provides a solution, it works:</p>
<p><a href="http://support.microsoft.com/kb/314082/en-us" target="_blank">http://support.microsoft.com/kb/314082/en-us</a></p>
<p>The blue screen has gone, however, it brings a new issue:</p>
<p>DP55WB does not have PS2 ports, I have to use USB keyboard and mouse, but the system can&#8217;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.</p>
<p>And again, Microsoft has another solution to solve this problem:</p>
<p><a href="http://support.microsoft.com/default.aspx?scid=kb;en-us;311504" target="_blank">http://support.microsoft.com/default.aspx?scid=kb;en-us;311504</a></p>
<p>Then, everything goes smoothly, it picks up USB stuff and eventually, the whole system work on DP55WB system.</p>
<p><strong>NOTE: when I do the test, I always use ghost to copy a backup hard drive to do so.</strong></p>

<p>A friend told me that his computer can not access some websites, like Yahoo, Google, IBM etc, but he can access other websites like Shaw.ca, cibc.com etc.</p>
<p>He use Shaw Internet without router, the IP address is obviously public. The OS is Windows XP professional SP2 Traditional Chinese Edition. The IE version is 6.0.2900.2180, 128bit.</p>
<p>Without doing any configuration for this computer, we moved it to my network environment: Telus Internet plus a router, so it gets private IP address, like 192.168.1.x, <strong>but now every websites can be accessed</strong>.</p>
<p>[Not finish yet]</p>

<p><strong>Delete all the Quarantine items from all anti-virus program running on the computer and it works.</strong></p>
