I am not a really big PC gamer, which is why back when i purchased this Toshiba laptop 2 years back i wasn't looking for anything fancy or expensive. It is running Windows7 Home Premium with a 2gig Athlon duel core, 3gig RAM and a Mobility Radeon HD 4200 inside. This was fine by me. The only games i play on PC are the Dragon Age games and Mass Effect series, and considering my low specs those games ran fine, if not perfect for me with medium to lower settings. Then came last month... when I had to send this in to a local shop for fixing.
What happened was that the GPU went out on the motherboard, or so i was told by the guy fixing it. He had to order a whole new, but same motherboard and install it. Took about a month or so. I finally got it back last friday, and everything seemed to be working great, if not perfect... til i loaded up Dragon Age 2 the next day. That's when the crashing started to happen about 5 minutes into the game. Now at that time i didn't get the display driver error. Then i loaded up Mass Effect 3, the game froze about 5 minutes in, screen went black and when it came back i got that "Display driver has stop responding and has recovered." After which Mass Effect went back to working fine for another minute or so... then freeze and error again. I can't seem to play any of the games i enjoy because of this error popping up now. Even with Dragon Age i getting the display driver error now when it crashes.
Now let me point out that before I had to send it in to get fixed I had no problems playing these games, now all the sudden i get it back and i get this crap.
I have searched all over the net for this problem and a solution, none of which have worked for me, and it seems in general this error can be caused by multiple issues. I've cleaned out all the drivers and re-installed 3 times, updated bios, and checked all other drivers and devices to see if their is any conflicts. None of which i can see or find, and so i have come here to this forum hoping to find some insight into what could be the problem in my case. I haven't really messed with the whole TDR registry thing, mainly because i get shakey when doing so since i screwed up my old XP machine years back. I don't think it's a heating issue cuz it doesn't seem to be getting any hotter then before i had to get it fixed. And as far as voltage goes i am not sure. My BIOS doesn't have any options for looking at that sorta thing.
Any insight would be greatly taken. Maybe the shop installed something wrong, or didn't connect something right...
