Having problems with your PC Desktops ?
I have just installed an ati radeon x800xt graphics card. system is 3 ghz p4, 400 watt power supply. I have plugged power in but fan is not working
When you are running low wattage power supplies, sometimes you need power from 2 locations within that power supply, Ie make sure you get 2 cables that are seperate from each other but still part of the same psu, which plug into your graphics card. Always work with a static wrist strap, you could of fried your graphics card. I'd say it's probably inserted into your motherboard, you just need power from the psu as well as motherboard to power this card.

I am working on an HP Pavillion a1220n Desktop and I am getting different bootups each time.

AMD processor? My computer died "slowly"...while using it the picture slowly darkened so I shut it off. Then when I tried to put it back on, there was no power...nada, no sound, no lights, nothing. I removed the cover, cleaned out the incredible amount of dust accumulated inside and around the fans and now the power goes on but nothing else happens. Has the processor overheated? I would like to try and repair this myself if possible. If it is the processor, where would this be located in
The processor is located under the large fan that is attached to the heatsink (large aluminum cooling device). The fan/heatsink will be located on the board itself, so it's pretty easy to locate.\015\012\015\012You should just need a flat head screw ... Gateway GT4010 (RBGT4010) PC Desktop
