Put the writer back in, disable all DMA and see if system remains stable. Infact, stress-test with this config if possible.
about my second problem. Umm...and won't disabling DMA severely impact the system's performance? I already have enabled the cpuspeed daemon so my system is already underclocked. I also dont think power is the issue because I used to run a DVD-ROM, CD writer along with the current config and never had any issues. My PSU is rated 300W. I think that should be sufficient.
I meant that for debugging purposes - not as a permanent solution.
BTW: i ran my Celeron2.4 underclocked @2.2 for almost a year before I bought that new PSU - for me that was a *good* solution. My old PSU was rated @ 350W - but it was the cheap local variety - so it probably didn't deliver.
The thing with hardware problems is that they are rarely deterministic - you never know which change might trigger an old itch. More precisely, the electronics are usually deterministic but the electricals are not. And it's near impossible to find someone having the *exact* same h/w config as yours for comparison.
AFAIK, cpuspeed for desktop processors is a farce. The core internally runs at the same speed, but only does work in a fraction of the cycles and no-ops the others. This translates to no power-saving and no cooling effect - just looks cool :-). It is only meaningful for Mobile processors where the clock frequency and voltage are actually scaled down in hardware.
