<div> <font size="2"><font face="Arial, Helvetica, sans-serif">What else was plugged in, apart from the USB devices? Some nearby ports will affect the USB ones, so removing the peripherals you don't need might work.<br>
I think it's a voltage/current thing, as there's an extra load added for each connected device plugged in, so try a higher-rating power supply and the BIOS settings.<br>

<pre style="font-size: 9pt;"><tt>Hi,<br>
<br>
This morning my machine started up fine as usual.<br>
<br>
I then put in the USB memory sticks I use for backups throughout the<br>
day. I put them in one at a time, pausing between each one to allow<br>
nautilus to start up and show it before putting in the next one. When<br>
the fourth one went in the machine froze. No keyboard or mouse response<br>
at all.<br>
<br>
I pressed the on/off switch and the machine popped up the GNOME shut<br>
down dialog and after 60s shut down. I then rebooted and discovered that<br>
none of the USB ports was working---no mouse or keyboard. The machine is<br>
old so I plugged in a PS/2 keyboard and that worked, but the USB ports<br>
were "dead", and not even the network card was working. I rebooted and<br>
tried the gentoo system rescue disk; that started fine, but still no<br>
mouse and only the PS/2 keyboard.<br>
<br>
Now, several hours later I've restarted the machine and everything works<br>
fine!<br>
<br>
I've never experienced this before. I think I bought the machine in<br>
2006---d'you think this is a "foreshadowing" that the machine is likely<br>
to fail permanently soon and should be replaced?<br>
<br>
I spent this morning visiting various computer shops and was pretty<br>
disappointed. I brought a Ubuntu live CD and did try it on one machine,<br>
but it didn't recognize the graphics card, so I suspect that buying a<br>
replacement won't be easy.<br>
<br>
Any shops you'd recommend for getting a custom machine, or is it easy<br>
nowadays to build one's own? Or is it easiest to just buy a Dell since<br>
they can supply their machines with Ubuntu preinstalled?<br>
<br>
