Yesterday, I had a few hiccups with my computer (with the ti4200 8x I bought about a fortnight ago). First off, I had the PC on, and I went downstairs for a bit (turned the monitor off, and went away as normal). I came back about an hour to 2 hours later, and turned the monitor on and knocked the mouse, only to be presented with an "Out of Range" box bouncing around the screen with the Hz randomly changing. My thinking was "WTF?!", so quickly hit the reset button on the case and rebooted the machine. When it had rebooted, it was all OK, but a while later (after playing Q3), I exited the game to desktop and there were little jittery lines all over the screen. I tried opening WinFox to check temperatures on the graphics card, but I couldnt read anything on the menu (was garbled big time), I then took a screendump to paste it in Photoshop (to see if it would show the little glitches) but the PC froze half way through Photoshop initialisation, and then rebooted (didnt see any blue appear onscreen as in a bsod). It rebooted fine, but I quickly uninstalled the 41.09 drivers, installed the 44.67 whql drivers from guru3d (got the link from the nvidia drivers thread) and re-aligned my 11" deskfan blowing into the case, and it was alright until I turned it off to go to bed. I have to admit, its a bit worrying... I'm not sure if its a sign of a dodgy card, or if its just a heat issue as my bedroom was the hottest room in the house yesterday, even with the window open and the deskfan on (albeit aimed in the pc), so it could just be heat and I'm worrying about nothing... still a problem if it wont keep running stable (like it had until yesterday). Could it also have anything to do with the driver set? Although I had aimed the deskfan more in the PC at the same time... Thanks for any advice given... I'm gonna phone ebuyer later today if I need to, so I can arrange a replacement.
