So, after more than one month, I have got my lifebook back; at the official service they did not found any mistakes on hardware, nor software. I was told Windows 7 are installed correctly; as well as all drivers. Although they did not found any problems, they changed the motherboard. Only two hours after I received my laptop, it froze like always. And it froze again three times that day. I brought it back to the store, and they sent it back to the Official Fujitsu service. Ten days after that, they call me, "no problems found", but I will get the same laptop from the store, and the mine that "freezes" they will keep.
So I have a new laptop for less than 24 hours, have fresh Windows 7 Pro (legal of course, but now the version in Croatian), all the drivers, that I have checked from Fujitsu DeskUpdate.Guess what???!!! It freezes again!!!
I have tried to work with laptop with and without my external hard drive (Verbatim, Model # 53030, 500 GB), with or without my internet usb drive (Huawei Mobile Broadband E367), for which I thought they could interact badly (??) with my laptop. Both drives are new (HDD 6 months and Mobile one month), and they both work perfectly on other computers (at least two laptops and three table computers).
I have Microsoft Office Suite 2010 installed (original), Adobe CS3 Master Collection (that works/ed on all my previous computers).
Everything is legal, correct, normal, and clear, like always before, since I work with computers, but this laptop is a real exception.
Does anyone has any idea to help me?
Thank you very much for your help!
