Weird laptop crashes/freezes (very frequent and random).

I just got a Toshiba Satellite A205-S5804 laptop given to me to “Fix (reinstall) the ubuntu” and I can’t get the thing to remain stable. So far I noticed that *SUSE and windoze run perfectly on it (no crashes), but any other linux OS or *BSD crashes very frequently and randomly during boot, login and when you’re using it).
The specs of the laptop are:

Ran memtest86+ and found no errors, ran the S.M.A.R.T tests, both short and extended and found no errors, the laptop doesn’t run hot and both thermal zones have 49°C at heavy load, so no RAM,HDD or temp issues, cleaned vents with compressed air and added thermal paste to the processor to ensure that there are no heat-related issues. Only thing that changed is that the client upgraded the BIOS around 2 or 3 months ago.
Can this be some sort of (quite odd) hardware issue. Or some sort of BIOS/hardware DRM?
BTW: Someone at LQ reported a similar oddity with an Alienware PC (and someone else showed up with a Toshiba laptop too, this time his issue was with Fedora instead of Ubuntu) just acting up with ubuntu & Fedora.

Just confirm
Are you asking about installing Ubuntu? What version?
