My motherboard and processor are under two years old and have always worked happily with OpenSuse, and recently with OpenSuse 11.3. Now my screen display has started to break up, with mouse and keyboard locked. The only route out is to turn off the power.
This happens whether I am in OpenSuse or just at the boot up display. If I restarted it happened more quickly, to the point where I could not boot up. I assumed that this was due to overheating, though the CPU temperature was about 42 C and the motherboard temperature seemed OK (around 30 C with the case side removed). I installed a more effective CPU cooler, which took the CPU temperature down to 23 degrees C, but the problem has persisted.
When I left the power switched off overnight, the system ran for a few minutes before freezing again. (When frozen, the screen is broken up but blinking.)
My system is pretty simple/;
Asus P5Q-EM motherboard with built in VGA (no separate video card).
Intel E8400 CPU.
I am not very expert with the system logs, but tried to access them when the system stayed up long enough, but saw nothing that seemed to tie in.
Is there any way I can tell whether the motherboard or CPU need to be replaced? As the system fails even when I am at the BIOS boot up stage, I assume it is not a software fault.
Please paste the results of lspci
It might be this bug. https://bugzilla.novell.com/show_bug.cgi?id=615649
If it is, and please read the entire bug and all the posts, then one solution is to edit /etc/X11/xorg.conf.d/50-device.conf and add under where it says Identifier, under that add Driver “intel”
Caveat: you may also need to update your xorg-x11-driver-video and possibly your kernel. I’d suggest kernel 2.6.35 For the repositories, see here Index of /repositories Use wisely.
I note an Intel GMA X4500HD on that motherboard, but a brief search did not indicate many others with the same problem … Thinkwiki suggests it should work with the 2.6.33 kernel in 11.3 : Intel GMA 4500MHD - ThinkWiki
I swopped the PSU but found no change, stripped the system down to bare essentials, but found the same happening and happening somewhat sooner. Even during the BIOS boot up period the screen breaks up and the system freezes, which would seem to imply that the fault is with hardware rather and not Suse software.
The motherboard has on-board graphics so Plan B for me is to replace the motherboard.
