|Everything worked perfectly fine up till a couple of weeks. First sign of weirdness came while working in Photoshop: a crash and no video signal while working on a file with the "Enable OpenGL drawing" option activated. After that, a couple of days later I tried to play a DVD, but after 15 or 20 minutes the screen freezes, then goes black and my monitor´s light starts flashing as if it doesn´t get a signal (I checked the monitor with another computer and it works perfectly well).|
Since then, I haven´t been able to play any DVD, and sometimes even regular avi files (at least for more than 10 minutes or so): the screen always freezes first and then the video signal goes off, forcing me to reboot via reset button. One of those times, as a matter of fact, after a perfectly normal boot sequence, the system entered windows (I know ´cause I could hear the Windows welcome sound) with no video signal.
Any ideas? Should I just change my video card? Or is there any possibility this is software-related (though I didn´t install any new programs or components lately).
Thanks a lot!!
