I just got an upgrade from Vista to Windows 7, plus I wanted to play Maple better on my crappy Slimline HP s3100n computer so I bought this card. Mine is exactly the same but the 256MB model. Everything went perfect for like around 1month.

I looked at the connection on the back of the pc (DVI to VGA adapter) but eveything was good. No beeps, all fans working, nothing loose. So I had to change the monitor connection to the one on the motherboard and it worked.When I logged in, I noticed the PC slower so the 1st thing I did was to check for the Video card in device manager, and It was not being displayed. So now I had a bigger problem. Unistalled the latest drivers from nVidia and reinstalled them, went to a previous restore point , around 4 days back, but nothing. I even went into the BIOS to change the main video adaptar to PCI-E and to default settings, nothing. So im thinking, "the fan spins, at least is getting power", so at this point I don't know if is the PCI-E slot, the card, drivers, BIOS or what the hell. I went on to a friend's house to check the card, but same thing happened, well a little worse. The card was getting power (fan spin) but the card wouldn't display anything and if we changed the connection back to the VGA slot on the motherboard it wouldn't work either. The only time the PC could display anything was to boot it with out the card installed. Back at my house I installed the card and went to sleep. In the morning I turn on the pc and WTF? The VGA slot in the motherboard now doesn't work now, so the 1st thing I do is to put the adapter and try the video card slot and works. GREAT! ..But only for 1 day, I turned on the PC in the morning just to find out the same thing happends. No display from the card, and not detected by the system and fan spins. Only one new thing comes to my mind, the power supply might not be enough to handle the card, since it says it neads a 350w power supply and mine's 160w, but why would it work for several weeks and then not? Any help?
