no reboot after crash

[beligun]

Hello,

I'm new to ubuntu, was using FreeBSD for a while, so I'm not entirely new to unix.

Installed 9.04 (?) and upgraded to 9.10. After upgrade at some arbitrary point the system freezes. Only a hard reset gets the computer going again. However, when the system reboots again, I get the ubuntu logo and then a black screen - that's it, no login, no nothing.

First I thought it was a glitch, so I re-installed, re-upgraded and voila - same old thing. This stops being funny. Can anybody tell me how I can get the system going again without too much effort and what might have caused the crash?

I running x86 9.10 on P4 Dell GX260 without any fancy hardware.

Thanks!

I have a GX260 and have the same sort of problem.
I have tried upgrading from 9.4 and clean installs of 9.10 but I still get the problem booting up and when I manage to get in the system will eventually freeze.
I have been looking for a solution since 29th but with no success.
