Ive recently purchased myself a new computer and at first i really liked it. It ran everything great and was a nice upgrade from my old 1.6g gateway that was about 7 years old. Ive had the computer for about a month now and ever since ive had it its been freezeing during games. Its a complete freeze, cant alt tab or Ctrl+alt+del. Only thing to do is to hit the restart button. I have tried everything i can think of to fix this. I have all the latest drivers, I've ran memtest for hours and hours with no errors. The PC is quite cool, usually the cpu is running at about 40-50C and graphics card is about the same temp, of course the temps rise a bit during gaming. The freeze happens in every game i have, from old games to brand new ones. The computer never freezes during internet browsing or simple tasks but does freeze during a prime95 torture test. Usually it doesn't last long in prime95, maybe 20-30 mins but it seems each time i run it it increases how long it lasts in prime95. to top it off after i run prime95 a couple of times it seem to make games run longer without freezeing but after a while the freezes become closer and closer together. I've called the manufacturer about this and they thought it was a problem with the cpu or motherboard so they sent me replacement ones, but the problem is still there. They seem to not know what the are talking about over the phone half of the time so i am resorting to my own methods. here are my computer specs: intel pentium D 3.20ghz cpu abit IP-95 motherboard nvidia 7300 gs 160gb Western digital sata hard drive 585 watt orion power supply 1gb DDR2 ram running XP home edition SP2 Any help at all would be great cause i am totally lost as to what the problem is. I have some spare parts that i can swap in and out so im all ears as to what to do now.
