this is from a previous subject. upgraded my processor to an amd athlon 3200xp -baron and also upgraded the ram to 1gig cp3200. my motherboard is a gigabyte ga-7vt600-1kt600. i also upgraded my graphics card from a NVIDIA GeForce MX440 with AGP8X to 256mb nVidia Geforce FX5500 8* AGP graphics video card. i was advised on this forum to install a new power supple so i did. it is now a psu 650w triple fan 24p and my cpu cooling fan is an artic cooling copper silent 2. it still freezes after 10 minutes(this is the whole computer). could it STILL be over heating. can you please help as part of my job i need to be able to burn DVDs. i also tried a different burner to the one i usually use and still no joy. i've also tried updating my bios as well. it also freezes when i'm on the web and there's one or two other things are running. this is driving me crazey. i really need someones help with this as i've spent quite a bit of money on this and thought i'd done everything right.
