Hehe I guess the GT220 cards are a tad bit unlucky.

Thanks for all the help, and now to look up some cards I can afford.:)

I would take the video card back out and clean the contacts with a pencil eraser and try it again before buying a new card. Amazing how many times contact is restored by cleaning with pencil eraser.

Pencil eraser works fine (as long as you make sure you know where the shavings drop
alternatives: Q-tip with rubbing alcohol (that's what I use most of the time)

One of those fiber glass pens from your automotive shop (the ones used for prepping touch ups) but be careful with those.
or fine grid sandpaper (I'm talking 1200 grid rather hard to come by....not the 150 or 200 grid from home depot
also a damp sponge, dipped in chalk or plaster of paris...the possibilities are endless...
Just so you know....when all the "golden" is gone, you did it wrong

As far as wearing latex gloves, I would recommend using an ESD strap or nothing. Latex is an insulator and will build up static charges that grounding your body will not dissipate. It is really much better to maintain contact with the system chassis to disipate any charges than to wear latex gloves. Additionally most latex gloves have dust on them that you probably do not want to get in the system.

You have a point there, I'll take a look in the local computer store for an ESD strap.

I'll try a few of those methods, got nothing to loose :)


Well i was thinking of buying some molex-2-sata connectors so I could use my old 400W PSU but they're incredibly expensive and it was cheaper to just buy a new 420W PSU lol

I'm an electronic technician by trade and my advice is to avoid cleaning the gold contacts on the video card with any kind of abrasive substance. The last thing you want to do is scratch the surface or wear any of the gold coating off. I only ever use isopropyl alcohol or contact cleaner. If you wear the gold coating off the contacts will oxidize very quickly and it will cause nothing but problems. Just my 2 cents.
