Could someone please help me with this. I recently built a computer and when I run a program with any sort of graphics more advanced then the desktop or the internet the computer will reboot. Here's a run down of what I've got. Intel Celeron D 340 2.93Ghz / 256K Cache / 533 FSB / Socket 478 Mach Speed Matrix P4M800 Via Socket 478 MicroATX Motherboard Ultra / Intel Pentium 4 up to 3.06GHz / Ball Bearing / CPU Cooling Fan Ultra / V-Series / 350-Watt / 120mm Fan / Power Supply 2 Ultra 80mm fans. 1 sucking air in, 1 blowing out. 160 GB HD 16x DL DVD ATI Radeon 9200 256 1 gb pc2100 256 pc2700 I've ran Everest and Warpspeed which came with my MOBO and both say that my temps are fairly low. Nothing over 50c. Could there be something wrong with my video card. I know it is old. Please help. This is frustrating me to no end! Also the FSB is showing as 133 in everest is there something wrong there?
