Random freezes are hard to diagnose. Personally, I'd check the memory first. Boot up a Live CD, and run Memtest a minimum of 10 complete cycles to allow the algorithms to put a hard load on the memory.

It might be something as simple as a bad stick. If it's not that, it'll probably be quite a puzzle to figure it out. (Been there...)

Good luck.

There is a lot of problems there could be.
I had a similar issues with my old Compaq, and wrote it off as a CPU problem. Come to find out, I think it was the internal video card all along, as I am now using it as a server and it hasn't locked up in 23 days!

The video card in mine probably had a glitch or was overheating causing the screen to freeze. Of course, now that I am using it as a server, I never have this problem anymore.

But it could be RAM (as OrangeCrate suggested), CPU (doubt it), Video card and possibly other components.

Orange-unfortunately I do not have the cd right now so,I guess that's kinda outta the question ? Hmmmmm ? I have down an extremely long long [hours] memtest on this pc before & every thing seemed fine.But,it has been a couple [2-3] months.

Thanks very much Dr.

Like they say it could be many things. I had a problem with mine getting to warm after being left for a few hours. Found a thread that said screen savers will keep using cpu until the use it all. I switched to the all black and haven't had a freeze on starting back since.

Yeah, that was one of the first things I noticed when I moved to Ubuntu two years ago. The screensavers really hog the CPU. I think they should make a new screensaver set for Xorg, that are not quite as CPU intensive. I set mine to a text screensaver, which shouldn't use to much of my CPU.

Didn't think of mentioning the screensaver. As said, that's a good place to look for a problem, after eliminating faulty memory.

On a fresh install, one of the first things I do, is dump Gnome screensaver, and install xscreensaver. Do both in Synaptic. (I'm running xscreensaver on both of my machines - fade to black screen only.)

Could be a bad hard or power supply. I am having kind of the same issue except with a different OS. I am going to run some tests this week to see if it is a dieing hard drive or a dieing power supply. Try using a different power supply and run some tests on your hard drive.
