All of the sudden I'm having trouble burning cd's. I recently changed out my dvd burner as well as my cd burner. I now have an Optorite(sp) cd burner along with a pioneer dvd burner. I've been burning cds in the optorite and 1 out of 2 are being made basically. I'll make an mp3 disk and it'll say it's full, but when I put it in a player it won't play for example, the first 20 songs, but may play 21 and 22 and then not play anymore til 80 or so. It's weird. Same way with regular music cds I burn. It'll play the first 4 songs, then if it plays anymore of the songs they sound scratchy and that's if they even play at all. Disks look ok, clean and I've used about 50 out of a 100 count spindle. Same thing is happening with my dvd burner too.I'm wondering if a memory problem could cause this, or a chipset fan or something related like that. Any help would be greatly appreciated, thanks.
