I have installed both the 64bit and 32 bit versions of 10.10 on my Compaq Presario PC.

I first installed the 64 bit version of the OS.The video often crashed when switching user. It also went haywire occasionally when I visited some web-sites. I read that there may be some problems with the 64 bit OS. So I installed the 32 bit version on another disk. This version seemed even less well behaved.

HP's model number for the computer is SR1838NX. The hardware is listed at

I think the important info is that the chip set is "ATI Radeon Xpress 200" and the processor is "Athlon 64 (S) 3700+ 2.2 GHz"

Has anyone else had video problems with similar machines? Is there a work around or an update? I have had previous versions of Ubuntu working on this machine and other flavors of Linux as well.

Thanks in advance. John
