I have bad luck with Nvidia Geforce GO 7900 GS

Thread Starter 
I have a Dell Inspiron E1705, Core 2 dou, 2 GB Ram, Very powerful laptop. I have an ATI Video card in it that I've been trying hard to upgrade to a Geforce. I bought 6 till with no luck at all, I bought all of them off ebay, the last one was a couple days ago, when I got it, I installed it and everything was working perfectly, I was so happy cuz this is the first one that actually works, after 1 hour of using it, red flickers started appearing on the screen, I restarted, tried different drivers, tried placing it again.. no luck at all . Now I have different colored lines and blinking pixels all over the screen, the background changes colors.. yellow, red, green.. and its not just on windows.. Bios, safe mode, everywhere.. I put my old ATI back and everything is working fine. I'm planning to send it back again to the seller, I attached some pics. I have a 90 w adapter but I dont think its a heating or power problems. Please any help.?

the 90w power brick is fine for a 7900gs so that shouldnt be your problem, It seem that you have yet another dud card. I bought mine from premiselaptops off ebay and its fine. I know they have another for sale. You have had some really bad luck.

If ATI card works fine, its the new cards that are the problem

People on ebay who sell dud cards should be taken into a back alley and shot

I've heard you need a 130-150W PS for that card... With 6 cards, quit sending them back - I'd think you have something else going on.

ebay is absolutely flooded with shit cards.

they are re-curculating.

I bought 2 in a row that were shit.

I won't buy from ebay no more for cards.

funny cuz it's gonna cost me like 800+ for my second 8800gtx

Were you able to get 100% refunds or good exchanges for those ebay cards?

I got exchanges from one seller, he send two at a time so I can test them and see if they work.. all the rest gave me my money back, I lost more moeny shipping back than the price of new card..

Stop buying 7900Gs cards and start buying fx1500/2500 cards. The fx1500 is the same as the 7900gs and the fx2500 is the same as a 7900gtx

This is really retarted but inspect your connector on your motherboard. Sometimes the pins are either messed up or I've seen cases where there was a small sticker preventing the pins from making contact.

Incorrect - you need a 130W PSU if you have a
7900GTX/7950GTX/FX2500/FX3500 period.

Seems like you have a worst luck but there have been plenty of reports of faulty 7900GPU's - the only other option is to contact Dell and buy direct this may not be the cheapest option but at least you will get a card that works.
