Burning problems with PX-W124TS

When I’m burning CD’s my computer crash, the screen is freezing. I have to
push the resetbutton to start my PC again.
I used Win98SE with Nero and PlextorManager v.1.09.
I try to setup the PC again with only Win98SE and Plextor Manager installed,
but the same happens.
My computer: - PIII-500, 256Mb Ram
- Abit Be-6 with latest bios
- Matrox G400DH with latest driver
- Western Digital 20Gb HD ATA66
- Plextor PX-W124TS firmware 1.07
- Nec DV-5500A
- Scsi controller: Adaptec AHA-2904
