Installation stuck while setup ist at 1 min resttime

[stony]

Hello,

- installation stuck while setup ist at 1 min resttime; installing a secound time without formattig Leo partition didn't help
- one time I've chosen some kext's (sound, graphics, etc.) ohne time I used to install Leo without any extra kext; nothing worked
- it doesn't matte if I chosse 9.1.0 or 9.2.0 kernel; no success
- I selected every time EFI MBR to install

At the end of installation, DVD stoops to turn in the drive and animation of loadinbar (the blue one) stopps.

My System:
CPU: AMD Athlon 64 3200+
Motherboard: MSI K8TNEO2-F V2.0 | ChipsetNorthbridge: VIA K8T800 Pro
RAM: 1024 MB (Infineon)
Display: GeForce 6800 GS (Asus V9999 Gamer Edition)
Lan:1000 Mbit Realtek 8100S


What can I do?
