I think on this one i'll stand by what iv said befor Windows (of any kind) is unstabel so you shouldnt expect it to work at all so your prety lucky

, no seriusly windows is unstabel and iv discoverd that unless you have the lastes technolagy, system stand by and habornate are liky to fail, also if your settings in your bio's are wrong then you have no chance and i wont help you with the BIO's as it can have ALOT of settings and any one of them could cause it, but most likly the power saving/wake up events setings are wrong, but if there not wrong then it'll never work properly
