hi everyone,

am using gateway laptop, athlon64 processor, 1 gb ram, dvd r/w drive.

recently i have been recording cds and dvds (apparently), which are not getting recorded.
was using windows xp home, and nero 7.

the disks are getting recorded. there is this colour change at the back. but when i insert them back into the comp again, the computer doesnt read them, not this nor any other comp.
at first i thought that maybe its the software, so i switched over to vista and nero 7 (again for vista).

same thing's happening. am recording, colour changing at the back. but the cd's blank.

and yeah only thing that seems to be working is nero vision, that actually records and playsback. so its not the hardware/or maybe it is.

what could be wrong here?
