Hi<br><br>I have had my ThinkPad for just under a week. The day it arrived I upgraded it (maxxed the RAM to 2x512MB sticks, upped the hard drive to a 60GB and fitted an Intel 2200BG internal wireless card without antenna) and installed XP Home and Ubuntu 10.10.<br>
<br>It has been running fine and I haven&#39;t changed the hardware at all.<br><br>This evening it started locking up shortly after boot. It will run for about 2 minutes then lock up. It requires the power button to be held down until the machine turns off. This has done it about 5 times in the last hour.<br>
<br>My default OS is Ubuntu, so I booted into XP and it doesnt do it. I am writing this email on it in XP and it has been running fine for about 30 mins.<br><br>Any ideas?<br><br>Simon<br clear="all"><br>-- <br><span style="border-collapse: separate; color: rgb(0, 0, 0); font-family: &#39;Times New Roman&#39;; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; font-size: medium;"><span style="border-collapse: collapse; font-family: arial,sans-serif; font-size: 13px;"><span style="font-family: Tahoma,Verdana,Arial,sans-serif; font-size: 13px; color: rgb(42, 42, 42);"><pre style="white-space: normal; line-height: 17px;">
