I have started having a strange problem. At certain times, after Windows boots, the screen becomes pixellated and ultimately the machine freezes. I have no option but to reboot. But once I reboot the system, it runs fine even for long hours. This only happens after windows starts. If this pixellation doesn't occur, the system runs fine. And at some other times, if the pixellation doesn't occur, Windows shifts to a 800*600 resolution, and gives a Graphics Driver Error Code 43, which it also gives every time the pixellation occurs.
I have reformatted my system completely, but to no avail. I have even tried changing the hard disk but the same problem occurs. The graphics card is barley a month old. I have also tried different versions of the NVIDIA drivers. There is no problem with the monitor, I've checked it out with a couple of monitors and the same thing happens. Could it be a problem with the hardware?
