My windows 7 works flawless except when I play games I get random freezes with looping sound that can last few seconds and sometimes this has caused for the whole computer to crash. This happens in Counter strike Source and Jedi Knight academy which are almost the only games I play right now. I have had Acer Aspire 7551 (laptop) for almost 5 months now. I'v updated my sound drivers and graphic drivers but it hasn't worked. I thought about trying to figure what motherboard this laptop has but I just have no idea what and can't see that anywhere to probably update it's drivers but isn't it that windows 7 instals those stuff automatically?
