I have an old PC but I get a problem. X Window or GNOME didn't work properly. On my screen appear "X startup error Line 1" and other errors. I tried to use "noapic" and "nolapic" but useless. Please solve my problem...!!!

My PC :
* Intel Celeron 2.4 GHz
* Motherboard Matsonic Model MS9388E
* Memory DDRI 512 Mb

Additional:
* Using VGA On-board
* Sis 661FX_760_741_M661FX_M760_M741

Sorry if my language is not good. I'm confused.
