<br>
</div>There is a problem with that. Whenever I boot without the 'nomodeset'<br>
option, the machine resets right at the start of the GUI (I just<br>
thought maybe it's when the Intel driver loads, or just about that<br>
moment). This happens in both CentOS and in Ubuntu, with Live CDs and<br>
with installations to HDD.<br>
<br>
Not sure what is causing that, but I can't get it to work without<br>
'nomodeset' option at boot... :-(<br>
<br>
P.S. My motherboard is Asus P8Z68-V LE, and CPU is an i7-2600S.<br>
