Thank you very much jcgriff2 for taking the time to look at my dump file.
By now, I have plenty of them on the minidump directory
I did exactlly what you said with driver verifier, but the PC started normally with no BSOD or any kind of problems.
Also, when I try to run msinfo32, it just opens the Help and Support window
BTW, let me describe another symptoms I'm experimenting.
My processor runs almost always at 100% after I run any install or some programms I used to run with no problems before, but speccially I've noted that when I install anything

The laptop becomes REALLY slow, even the mouse get lags, and I have to restart the computer in order to work again.
I really don't know what else to do

I'm thinking about refformatting and reinstalling all over again, but I'm affraid it'll be justa waiste of time as it was last time.
Should I just send it for a hardware fix? Maybe it's the mobo or the video (part of the mobo) that are having problems???
Thanks again
