[SOLVED] Karmic live CD and installation crashes

[SDL]

Hi everyone.

I have downloaded and burned 32-bit Ubuntu 9.10 but when I use the live CD it loads the desktop and about 10 seconds later the mouse and keyboard become completely unresponsive.

If I try to install instead of using the live cd, the initial installation screen loads but I cannot choose my language before the computer crashes.

The image md5sum was fine after downloading 9.10 and I have checked the CD for errors. I have also tried Xubuntu with the same result.

I am currently using 8.10 as I had the same problem with 9.04 except that I could successfully install that version. The problem was that having installed it, I had the same crash as with the live cd after booting.

Here is a list of my hardware, please let me know if I can provide any more detail:
Processor: AMD Athlon 64, 2000 MHz (10 x 200) 3000+
Motherboard: Foxconn 755A01/K8S755A Series
RAM: 1536 MB (PC3200 DDR SDRAM)
Graphics card: NVIDIA GeForce FX 5700 (128 MB)
HDD: WDC WD1200JB-00GVC0 (111 GB)

Thanks for reading.

Stephen.

P.S. In case anyone reads through my past threads, I am still booting with ACPI=off but I have tried without this command and it makes no difference to the current problem.
