Since all computer hardware is different from computer to computer. I can't answer that question with any authority Fred. Take it as it comes. I run the miniature version of Mepis 8 and update about once a week manually using apt-get in Terminal. No problems for the past year and I am also running Testing on another netbook. Which is pickier than a desktop when it comes to hardware. No problems there either. Mepis is one of the least known, under rated (IMO) Linux Distros that just works right out of the box. I have been running Mepis since 6.5 and it has never dissappointed me. Just run with it Fred and if you get any more Lockups, maybe it is time to buy a can of air and give your computer a blow dry cleaning.

My Gear is single core processors (except for my IBM M57 Desktop) with low specs mostly and I run modern Linux operating systems with no problems. But some distros won't work with my gear, and PCLOS and Mandriva were 2 of them. So I had to scout around till I found the right combo. I do know Mepis developers are very careful with their upgrades. And the rest is taken care of By Debian, which Mepis is based on. Your Version Of Mepis is basically a spinoff of Debian Lenny with a lot of Bells and whistles added like codecs.
Use the Mepis forums in the bookmarked section of your Iceweasel Browser. Bunch of nice guys there willing to help out. Introduce yourself there and explain how you came to end up using Mepis and explain about your PCLOS upgrade troubles. They will listen and give ya some good feedback. Happy Trails Fred and Enjoy your New O/S.
