I have a pretty challenging one here…I have an acer aspire 3100 model BL51 and the initial problem was that it had a black screen when booted up and the sound was all messed up. It did not go past the windows loading screen.
I replaced the motherboard and reinstalled windows media center on it. After loading the video driver for the acer it appeared to have messed up the screen and it was flashing like crazy. I uninstalled and didnt install any kind of video drivers. That appeared to fix the problem up until the customer received the initial problem once again. It turns out he downloaded a game and that appeared to have caused the issue. I would appreciate any assistance on this issue. This has been an ongoing problem and would love to squash this as it has kept me up at night 🙂
