A friend of mine got this IPC topnote f series model 200. It was working fine until a few weeks ago, she noticed that her cd-rom doesn't read any cd's and there's no sound coming out from speakers. She also heard a scratchy kind of noise when the system is booting, using modem. Basically anything she does she hears that sound. It's like something is interfering the sound card. Windows xp pro detects sound card and cd-rom find but they're not working at all. Upon inserting the cd into the drive, it spins for a few secs and stops and when you go to cd-rom drive, it'll say there's no cd in it. The sound is detected fine as well but there's no sound coming out of speakers nor earphones port. She hasn't droped or physically damaged the laptop. Sound card is sis 7018, and the chipset is sis 630 I think. We have downloaded and tried the latest drivers and it didn't help. We also tried using the cd-rom in real-dos mode, the driver loaded fine but the cd-rom wouldn't read cd's.
I'll tell her to go back to the shop where she got it from if there's no solution for it.
