    Do you get any response at all when you switch the PC on ? (examples: lights come on, the fan runs)



    Have you ever installed a power supply before ? Did you use and earthing strap while working on the PC ?



    Does the motherboard have a video connection as well as the one on the card you installed ?

You should only change one item at a time to determine where to start checking. If you have another graphics card or an onboard video connection use that and tell me the results. Also if it is an AGP card reseating it may fix it as that is a common fault. Steve

How do I get a evga gt 610 2gb graphics card to work with my pc?


If you have a black screen with a blinking DOS/text-mode cursor, and you're sure you disabled the integrated graphics, the card is bad or your power supply is not delivering enough electricity on the 12v line to start up the graphics card BIOS.

To check if it's your power supply, simply disconnect your DVD and hard drive from power, and your video card will have enough 12v juice. (the GT610 needs more than half of the power on the 12v line that the stockPavilion P6-2330 can supply). If disconnecting your drives fixes your issue, you will need to buy a better power supply to use them at the same time. One with 15-20A on the 12v line is ideal, a good price is $50 or less.

If it still doesn't display anything besides a blinking text cursor when your drives aren't connected, try re-seating the graphics card and make sure all the pins are completely connected, if this doesn't solve your issue, the video card is most likely bad, just exchange it.

If you have a black screen with a mouse, your new card is probably being used as a 2nd desktop. To confirm, just connect your monitor to your integrated graphics; if you get a picture, just set your new card to be the primary desktop.

GPU hardware not recognised


Hello the homepage is here:

http://www.biostar.com.tw/app/en/mb/introduction.php?S_ID=583#dl

Try to download a manual if you don`t have it.
If any drivers for the mainboard is missing install them.

Install the newest NVIDIA graphic driver from here:

http://www.geforce.com/drivers/results/49949

This is the 64 bit version.

Check also if the graphic card is properly insertet
in the slot on the mainboard.
And the graphic card has to support PCI-E X16
This graphic card needs extenal power
from the power supply to work
the power supply has a wire with pci-e stamped in did you connect this ???.

Try to disable the onboard graphic in the device manager.

Good luck

PC wont boot


Check your specs for this one on your Card (should be on the box or in your included documentation), but I believe your card is PCIE v2.1. If this is the case, your card won't work. Your mainboard is an older one, and you can tell by the black PCIE slot that it is only PCIE 1.0. NOTE: PCIE v2.0 cards will work with PCI v1.0 as long as they meet power requirements, etc. (yours should be fine) but there are no updates to fix this on your mainboard. Time to dig out your receipt and look over the return policy. Again, a PCI v2.0 should work OK, just not the v2.1 cards.
Please take a moment to leave feedback if I helped you out today.

Graphics card won't work on computer


I cant be sure since I can't see the error during bootup. But its highly possible that you forgot to plug in a extra power cord that goes into the video card. at the upper corner of the video card. you will see a black plug with 4 pins on it that needs a power source. You have that from your power supply that normally people use it for a floppy drive. Plug that in here and that should work. If it still doesn't, give me the exact error during bootup and I'll help you from there.

Your card is available at Newegg.com gforce 7300le for $70.     Any PCIe 16 card wil fit you computer just make sure that you have a large enough power supply to handle a card that would use more power.
