i have recently aquired a gateway gt 5056 it has a foxconn C51GUO1 motherbord soket 939 and an amd athlon 3800+ cpu it uses the large fan with the green air duct (for lack of the correct name) for cooling no fan directly on the cpu heatsink hears the thing: more than a one part question first, it freezes up after maybe 15 minuites it has 3 512k sticks of ram Kingston ddr 400mhz get this if i only use 3 sticks in post it says 2t single channel memory 333mhz ??? if i add the 4Th and last stick it says 2t dual channel memory 333mhz ??? it will go through the post but hangs up there all sticks are the same have tried rotating them in different slots and they work fine in other computers I've swapped out power supplies, hdd's,cables the works it takes forever to install xp or win 7 win 7 has always installed pretty quickly on my other machines sometimes i will have to restart loading the OS a couple of times before it will run long enough time to finish the install even freezes up on updates before they can finish all the fans are working and even put a 10mm fan directly on the heat sink in my limited experience the only time I've had this problem is when the CPU is getting hot but mine is simply a very little warm, case is sealed well i thought maybe it was because of some chipset conflict to win7 but xp is even worse because it takes longer to install the OS I'm using onboard video to avoid any conflict there whats up with that i don't even begin to get this. can you guys help me with this ?
