Hi, so i bought a zotac GTX 650 Ti 2GB graphics card and gave it to a professional at a store to install it for me. So what happened is that they installed it but for some reason it doesnt work with my specific computer. they took it out and put it in another one and it worked just fine. My computer is a Dell inspiron 660 with windows 8, I5 3330, 8 gigs of ram, 1 TB hard drive and like around 500 W of PSU. I dont get y it doesnt work, i mean it should because my computer meets all the requirements for it. I dont know what the actual problem to it is because my computer is at the store so all they told me through the phone call was that they couldnt get it to work.
Thanks!

also i just bought the computer so its new, and the orignial came with 300 w so the store had to replace it with the new 500w.

might be the power supply not giving enough power to the GPU... PSU will never give you full 100% wattage so your probably getting at best 400W which might not be enough. it might be time for a new case and psu...try those $50-80 cases like raidmax that give you a power supply with it. u MIGHT get lucky if you look for an itx psu but it's hard to get one that matches their model size. dell makes their psu specific for each line. Standard PSU will give you usually an unstable connetion because of cheap wire and cheap connectors. If the current is inconsistent, its possible that the GPU out of fail safe might not start until it gets stable power...this is just a guess. but i'd definetly try to look for a psu/case combo on newegg or your local component store.

I also think that it's the PSU. If the card isn't getting enough power, it simply won't work.

Does the computer work with the integrated graphics? If it does, then it must be the PSU.

I looked at the Dell Inspiron 660 online and I am assuming it came with the Intel Integrated graphics to begin with and then you added the GTX 650 Ti. If that is the case, did you turn off the integrated graphics in the BIOS? If not, then I would question how professional the "professional" is who is installing this for you.

Also, what brand of 500W psu did the "professional" put in there for you?

Don't try the "$50-80 cases like raidmax that give you a power supply with it" that mafisometal suggested. Those psu's are crap. Always use a reputable company such as Seasonic, Antec, XFX, and corsair.

The "professionals" probably put a no-brand PSU in and it can't supply the card. Since you have a new Dell, you probably have to go with a Dell or Dell-compatible PSU, as my understanding is that most Dell motherboards and PSUs are proprietary and non-standard, so you would fry their motherboard if you put a standard PSU in it.

Ask the "professionals" at the store to put a higher wattage PSU in your unit and see if the card works with it. If you can, try to get them to put a name brand in it, as "maui67" suggested, if those brands make Dell-compatible PSUs.

Not all PCI slots are compatible with every pci express GPU. I had an HP that didn't work with my old 9800gt. I did some research and found that its a problem but a not so common problem. I checked who made my motherboard by opening up my old pc and it was ASUS. so I went ahead and bought an ASUS hd7770 and it worked. (pure speculation) If it was a smaller company who made ur mobo. They may have realized that the pci-e slot had some compatibility issues but couldn't afford to redesign whatever they had to. Maybe they thought most people wouldn't use it either. Maybe the mobo has a problem with pci-e 3.0 graphics cards in a 2.0 slot. Ask whoever installed the graphics card to try other cards. If nothing works, try a pci-e 2.0 card.

so when i got my computer back they said that when they were doing to pre-loading or something like that, during the startup the motherboard recognized the GPU but didnt know what to do with it. So what they did was that since they couldnt do anything about it they put in the gtx 650 for free and now it works. Although its no Ti there shouldnt really be that much of a big difference right (im no computer genius). Also my PSU manufacterer is Coolmaster 525W.

There is nothing wrong with your PC, I personally don't like sending my PC to other parties to work on it cause you never know what might happen. What you do want to check is that you've downloaded up to date nvidia drivers for your card and whether you've connected your monitor to the card's port and not your on board integrated port that you got from dell. If all the installation is done right and your computer is not reading the new hardware then it's best to invest $90+ on a new 550W PSU (or 650W if you think you'll be modding to a Asus gtx 660 ti or higher in the future) try this one http://ncix.ca/products/?sku=66083&promoid=1305, usually one of the main components a PC builder would switch out is the default PSU a company like Dell puts in to ensure all the components are getting enough juice. Like others have mentioned on this thread

There is quite a difference between a gtx 650 vs 650 TI I would ask for a refund in fact the 650 ti has 2x the amount of cuda cores, which is basically the component that helps process your tasks for graphics. Market-wise you got suckered around 73$ (the difference between a 650 and 650ti).

Please do ask for a refund cause I'm pretty sure there is no problems with your PC or graphics card just the questionable "pro" service did they even tell you the difference between the 2 cards before they made the swap?

Next time you can take a look at a youtube videos on how to switch out components yourself in a PC and some small pre-cautions it is fairly easy. With a bit of youtube guides and tomshardware helpers you can save lots of money on services while learning about your own PC. I mean the PC is generally made in such a way that it is not as complicated as alot of people think, I mean every component has it's own different looking socket and plug (literally like fitting lego pieces together).

Oh yea I got a refund for my card. Also I tried installing it myself but for the life of me I couldn't remove the power supply pins from the motherboard. The big one was just stuck. So i no choice but to give it to someone else to put in my power supply and video card because i didn't want to break the motherboard.

I don't know about that. I installed a thermaltake 430 watt psu in my inspiron 660 along with a gt 640, and it works fine. It didn't say anything like ''dell compatible'' on the PSU box. It was just a generic power supply.

I have the same problem
First i thought it was the psu cuz i have 475w psu original from HP (my pc is HP XW4600) so i went to a pc shop and tried with a new 650w original power PSU but it didnt work, the IT man says that the GPU isnt compatiable with the motherboard,theres a conflict, it can be caused from a problem on that GPU or the motherboard isnt compatiable with these gtx models...so u can try other gtx with same model maybe they will work or another GPU!
:) 
P.S
Sorry for my mistakes

Dell used to use lots of motherboards and PSUs that were incompatible with the ATX standard, so replacing a Dell PSU with a standard ATX PSU could fry the mobo in those systems. I'm not a Dell desktop expert as I build all my desktops myself and have for 18 years, but from what I've seen on forums, I get the feeling more of their motherboards and PSUs are probably standard ATX now.
