Hello all,
I bought the following parts (from Scan) in early October and built them as a new system a few days later:
- Motherboard MSI H61M-P20
- CPU Intel Pentium G2030
- Memory 4GB Corsair DDR3 XMS3, PC3-10666
- HDD 500GB Hitachi 0J11285 Travelstar Z5K500
- DVD Samsung SH-224DB/BEBE
I initially installed Ubuntu 13.04 64-bit and noticed regular but random application / system component crashes (all manner of packages with segmentation faults from udevd to compiz to terminal and sometimes a kernel panic during boot).
I wasn't 100% confident in 64-bit builds so installed 12.04 LTS 32-bit instead. No improvement, similar issues.
Even from the 12.04 LTS 32-bit live CD I get similar instability (with the HDD SATA cable disconnected)
Around half of all reboots result in an eventual app crash, and when I see one problem it's normally followed by several others.
The other half of reboots are completely stable, I can run CPU stress tests + google earth + firefox with HTML 5 fish graphics test + several instances of supertuxkart for hours and not a single crash.
I've run memtest86+ for several hours (7 complete passes) without a single failure. I've tried debsums which returns good checksums for every package installed on the HDD.
Basically the 'random crash' behaviour points to a hardware problem, but any tests I run fail to find any problem with the hardware.
I'm running out of ideas so any suggestions would be much appreciated. If it was a motherboard fault how could I confirm this?
Thanks,
Jon.
