I was asked to take a look at someone's computer the other day because it kept freezing whilst playing games, it sometimes crashed or reset the computer. The computer is a new computer and has only been in their possession for a few days, with no internet access. I took a look at the specs and found that it was running on an Intel Pentium D processor 3400mhz, 512mb RAM and a Radeon X1300 series Graphics card (that's all the specs I remember). One of the game's that crashes the computer has a maximum requirement of a Pentium 3 Processor, 300 something RAM and I can't remember the graphics card requirement. I decided that it couldn't be because the system didn't meet requirements so I loaded one of the games (Theme Park Inc.). Then I opened task managed, and to my surprise the CPU usage was hitting 70% - 97%. I found this odd as it was the only program running and was managing to push the CPU to it's limits whilst at lowest graphics and audio settings. I did some research into the parts and found out that the Radeon X1300 isn't built for gaming and that it can also be given a part that allows it direct access to the systems RAM (can't remember the name of the part). I've determined that the graphics card is using the same RAM that the game and the operating system is using, and with so much going on during the game, the CPU spikes to over 100% and shuts down the game or the computer. Am I right in thinking this or is there something I'm missing or unaware of? Another theory of mine is that a slow speed Bus was used to connect one any of the parts and that's straining the computer.
