BSoD during Dota 2, never happened before and now I can't play.

Confirmed, chipset damaged. I used a GIF to confirm it, a well colored one. I can still run everything without the device activated but now I passed from 1366x768 res to 1024x768, and I cannot play games anymore... Now I'm running the PC with the video defaults (as if I haven't video driver)... Tried all versions of the Chipset driver, none worked at all. So my "half" fix is deactivating the "screen adapter" device on Device Admin, Control panel, Windows 7. Cons? low res, forget about gaming... Can still watch youtube videos, which is nice :)

Ill close the thread in two days, just watching if I get another error but for now I'll keep updating if there are more issues. Thanks Laith for the help

Have you tried running Seatools for DOS and Windows? Run it and if it gave no errors then replace the chipset im pretty sure it is its fault. SeaTools for DOS and Windows - How to Use

Already tried, no errors found!
Still thinking is the chipset since when I deactivate it, win 7 never gives me BSoD.

Well, until now I noticed that last disk checks from the cmd command reduced in 35GB my primary partition... So I wanna ask you this: is there any probability that video (drivers and performance) could be affected by a damaged HDD? I mean, since deactivating video device on the Device Manager solved me the BSoD errors I thought that my chipset was the main error but noticing that in fact, my Hard Drive was reduced, it means it was faulty so I don't know what to think already, by the way, I'm asking this because I don't know much about HDD-Devices relation apart from the drivers of course!
Is there something wrong if I try to install the Win7 on the other partition or better replace the damaged disk?

Oh sorry for the seatools for dos thing i didnt see the last post. I think there is a possiblty im not 100% sure about it but i think there is. But how is it damaged? Scratch on it or something? I think you should install Win7 on 35GB partition. Make sure it is not System Reserved, if it is dont do it will mess up your comp really bad. You wont be able to boot into windows and all that kinda stuff.
