Thank you for your suggestions. I have had no problems so far compiling my |
33 |
Gentoo packages, and I often stressed my system with lengthy computations |
34 |
without any issues. So I tend to think the RAM is good. |
35 |
|
36 |
I thought that power supply issues would tend to occur under stress, not under |
37 |
rest. But you are right of course, the problems may occur after some delay. |
38 |
Unfortunately I've no idea how to test this. |
39 |
|

I'll check the disk to see if something comes up there. I also plan to install |
41 |
Ubuntu on some separate disk and see if the problem occurs there as well. |
42 |
|
43 |
If these are indeed hardware related problems, I feel like abusing this group |
44 |
(which is software related after all) with my problems. So, I'd also appreciate |
45 |
suggestions which online community would be better suited for help with |
46 |
debugging hardware issues. |

Thanks, |
