Normally when I boot up, the cd/b flashes its light for a second and then switches off. Recently , but not all the time, the light stays on and my pc takes a long time to boot (3*normal). My pc works relatively normally but the light still flashes and I am unable to get the cd tray to come out so I can't use the cd/burner.
I am running winXP home and my modem is from the KM4M series, MSI/Mainboard for AMD Athlon XP/Athlon/Duron.
I have removed anything from the start up menu that might cause the problem, such as NeroCheck but it had no effect.
Thanks for any help you can give me.
