Having problems with GH22NS40

Hello guys and gals,

Recently I have encountered the next probelm with the LG gh20ns10 and the gh22ns40 which i got as a replacement because of that problem:
Whenever i am to burn a dvd (dvd-r) whether it’s data writing or image writing using origrams such as iso burner and imgburn the process doesnt move a bit. It starts, but never goes past that. Now after that the only way to open the dvd is by reseting the computer. Only the disc is getting wasted.
Please tell me what can i do to make it work.
My pc:
Intel Core 2 Duo e8400 3ghz
Asus p5n-t deluxe
3gb geil 800mhz
Thermaltake tr2 rx-500pp power supply
Windows XP Pro sp3

Thanks a lot.
