Hello, I am new here and I need some help. Computer Specs: Windows XP Pro SP2 Version 2002 Intel Pentium 4 CPU 3.40 GHz 1GB RAM Chaintech NVIDIA GeForce 6600 Video BIOS: 5.43.02.66.01 256 MB ForceWare:71.25 Power Supply: MAXTOTAL 480W At first I had a FoxConn motherboard and games worked for about 5 hours before the computer shut off. I tried to turn it on again and did not work. I then removed the power supply cord and put it back in and the computer would turn on till windows and crash. So I kept it off for a couple of hours and turned it on again. This time everything loaded like normal, seemed like it overheated. I played for 5 hours and the same thing happened again. So I decided to get a new, more known, motherboard. The ASUS motherboard had the same issue and I ended up buying a huge fan for the CPU. This fan cooled it very well and I knew this because of the ASUSprobe program. I wish I could say this helped, except it did not at all. Even when I play 2D MMORPG games, it takes less than 30 minutes for it to turn off. I don't know what could be causing this, the RAM sticks? Video card? Power supply? Any help is appreciated.
