5920G freezing

Hi All,

Just bought an Aspire 5920G (with 8600GT, bluetooth,..). I have a big problem, in that it freezes under both Vista (factory installed) and Ubuntu which i added. While doing nothing special, it will just lock up entirely.

I think, but am not 100% sure, it has only happened while running on batteries. I do know I tested stability under Linux by letting it running 2 instances of burncpu, while playing a 3D game, and it ran fine for over an hour (on the 220v adaptor I think). Later it would freeze while just typing something in the console, and in Vista while doing nothing special either ?

Any hints pointers ideas ? Its got the latest BIOS.. Anyone else having similar issues ?

 

Did this happen before you installed Ubuntu?

 

Im not sure; installing ubuntu was about the first thing I did. Its only when that proved a small disaster (not installing from DVD, needed to use a USB stick, no support for Wifi, standby and hibernate not working,...) that I started using Vista.

But I doubt installing vubuntu had any impact; I installed it it on the "data" partition, so it shouldnt interfere with Vista.

 

I think I found the cause: cpu throtteling.
When I run BurnCPU all the time, the machine is rock stable. I worked on it all day, played games, no sweat. When its iddeling there is no problem either. its only with light use, when the cpu speeds up and down.

I contacted Acer, and they will pick up the machine tomorrow for repairs. I hope they fix it, cause its a nice machine otherwise (despite my linux woes).
