i have the same problem with my computer....
- 450 watt power supply that came with my Xion II case
- 2x Serial ATA Hard Drives
- NVidea GeForce 6600 GT
- Floppy Drive A:
- 2x EIDE Pioneer DVD/CD Burner Combo Drives
- Asus K8V X motherboard
w/ AMD Athlon 64 Processor 3700+ 2.40 GHz
- 1 GB MB RAM
- 32 bit OS
I had one here in the shop that did the same thing.the power supply was bad so i took one of my known good ones off the shelf and hooked to it did the same thing.come to find out it was the memory causing it.
It depends, I had an issue like this where my memory was slightly out and had dust in the slot - and it could be an overheating problem -- try getting a hold of another stick of ram and test it out
