lockups after boot

[jeff1958]

I have a Dell Optiplex GX110 P 3 w/512 ram onboard video. I can install Ubuntu 8.04 with Grub with no problems. I install the updates then reboot after I log on I get wavy lines and the system locks up. I have tried it with and without the updated driver same problem. Mem test passed with no errors. My guess it's something with the video driver but I do not know how to fix it. Thanks in advance.
