Celerons do that if they heat up. 128MB might be too slim for PCLinuxOS.
Try DSL next.
Ok, I have a pc that I reset the CMOS on and booted back up. I decided to get an ISO Image of PCLinuxOS and boot it up on it. By the way the specs are: Intel Celeron 1.2ghz 40gb hd 128mb ram desktop. I got it to boot the OS up fine but after it logs on it runs so slow from the disc it freezes up when I doublee click on install OS to HD.
