|Tell us the make and model of your brand name system, or if you have a generic desktop system, the make and model of the mboard. |
The specific model of a brand name system is often shown on a label on the outside of the case somewhere, or it can often be determined by going to the brand name's web site and loading a program they have available, if Windows is still working, on the subject computer.
If it's a Dell computer...
Go here for how to find the Service tag "number":
Tell us what it is.
If it's a HP or Compaq computer.....
Scroll down a bit.
Look for the similar label on the outside of your computer.
Quote the specific model number - that's at the end of the first line.
Quote the Product number - that's on the third line.
The model, sometimes the make, of a mboard in a generic desktop system is usually printed on the mboard's surface in obvious larger characters, often between the slots.
The video card DOES NOT need drivers before Windows loads. The video card and the mboard always support basic video before Windows loads, and Windows supports basic video before specific video drivers have been loaded for the card's video chipset.
There is no reason for you to have no video while booting unless...
- your mboard has onboard video as well and supports Hybrid video but the video chipset on the card in the slot does not support Hybrid video with the particular main chipset - in that case you need to change settings in the bios.
- the video chipset on the card you installed in a slot draws a lot more power (amps at +12v) and your existing power supply does not have enough capacity to handle that (See below).
-the video card is NOT all the way down in it's slot - check that.
- you damaged the video card or the circuits of the slot you plugged it into or both because you DID NOT unplug the computer or otherwise switch off the AC power to the computer when you plugged in or unplugged the old card or the new card.
- you neglected to plug in some connection to the power supply that your system requires for the mboard or the video card in the slot. If the card in the slot has one or two power sockets on it, there must be a suitable wiring connector from the power supply plugged into it / them.
The mboard usually has TWO power sockets you must plug a connector from the power supply into.
Your power supply must have at least the minimum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD ! )
If that info is not in the ad for the video card, you can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.
If you're a gamer...
In most if not all cases, the max capacity rating of the PS is an intermittent rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should get.
If you need to get a PS with more capacity, you can usually replace it with any decent quality standard sized standard ATX PS.
Standard (PS/2) power supply size - 86mm high, 150mm wide, 140mm deep, or 3 3/8" h x 5 7/8" w x 5 1/2" d , or very close to that, though the depth can be more or less for some PSs.
Don't buy an el-cheapo (in quality) PS.

Note - I may have mentioned Coolermaster in that - I have recently found some models have only a 1 year warranty, some are known to have premature fan failures, some are known to develop failing electrolytic capacitors.
