Hi all,

My linux desktop freezes randomly. I mean it stop all process, It doesn't response any key event, It even doesn't change the led from the keyboard when I press lock keys. I tried with and withoud NVIDIA official drivers. I remove 2 of four RAM modules, because I realized that It generate incompatibility problems, since then Windows 7, works fine, but linux don't.

I also tried Open Suse but the problem was that the system gets unresponsive from keyboard and mouse (this problem was different from previous because, in this case I could see the torrent downloading). I don't know if this issue can be related with the previous one.

Can anyone provide information about whit issue?
Thank you very much.

Linux is very sensitive to memory problems, which I would bet is your problem. The first step you need to do is run memtest to make sure your memory is ok. You should be able to run it from your OpenSuse boot CD. Choose memtest from the boot menu and let memtest run to 100% through at least one pass. Twice maybe if you don't get errors on the first pass.

If you don't get any errors, post back. Right now, a memory problem is your prime suspect.

When you post back, also include your system specs including the amount of memory you have now. It could be you're hitting the swap file a lot if you're running with a low amount of memory because of the modules you removed.

yes, probably a memory issue. Please post your system spec as it was mentioned. Also try to check temp sensors and hard disks (especially your system drive). Try to boot from live CD

Thank you for your responses

I ran the memtest with two differents couples of memory modules with the same result:

The test failed for both couples on 44%. It is very strange that both couples have problems so It can be posible that it is a chipset issue?

And finally, why Windows run without troubles with the same memory?

Linux uses memory differently than Windows, and for whatever reason, it is more sensitive to bad memory. I'm sure problems would eventually arise in Windows too. Maybe programs crashing or other anomalies. It's definitely a good idea to get the problem taken care of to be on the safe side.

Check your motherboard manual about memory arrangements. Some boards work best if certain dimm slots are occupied in a certain order. Also, look up CMOS settings. You may be able to get the memory stabilized by increasing the memory latency. This is especially necessary if you perhaps have your system overclocked. Sometimes memory can be detected at the wrong speed too. Increasing the latency can help with that. (For example, set memory to CAS Latency 3 if it is set to CL2).

During the freeze try:
Ctrl+Alt+F2 that should get you to the log in screen.

If it continues to freeze it (could) be a dust issue or fan issue-

Is the side of the tower where the motherboard is warmer than usual?
If so, you can run this cmd and keep an eye on your systems temp:

One or more of the RAM sticks is bad. It's likely that just one of them is bad, so try one a time with memtest86+.

A number of steps that you should try: (You may have already done some of them)

1. Run memtest

2. If RAM passes the test, go to step 4; if RAM doesn't pass go to 3.

3. Replace all RAM

4. Check Linux compatability with your PC. Some PCs just don't work that well with Linux!

And remember, google is your friend, research, research and more research!

RAM is not as expensive as it used to be.
I was just at this store yesterday and they have good products.

You mentioned:
If it were my computer I would purchase a card other than Nvidia-

Maybe the new Radeon (just a suggestion)
