Either the graphic card is not compatible or the power supply that you changed is not fit for the motherboard....
check this
1 switch on the machine....if u can view / hear the fan on the power unit at the back of the PC running then the power unit is working.
2 do u get any msg or charecter on the screen when you power on the manchine ? if yes then the graphic card is the issue....
3 the cables inside the PC that you connected of the power supply are not properly joined in the MB

well at the last i will ask if the PC was new why did u make an upgrade....u could have bought a better PC with the extended features ??? well that's ur choice...!!!

ok then....
just put back the original power supply and original graphic card to c if it works now....
then let me know pls...
regards

Best is to buy a new laptop with fast processor, plenty of RAM, & a powerful graphics adapter (preferably NVidia or ATI) with plenty of video memory. The exact choice will depend on how much you are willing to invest in these main components.

I am trying to play a pc game but it keeps saying my graphics card does not meet the minimum spefications how do i upgrade it?


graphic cards usually are made to a DirectX level the most up to date cards are at DirectX 11
check your game and see what direct X level it requires. it may well be that you can download and install direct x to the level of the game, if the graphic card you have will accept it.

if not the next steps could be expensive, if you are looking to buy an new pc soon anyway then i would not bother to buy a new graphic card, then better a new pc with a decent graphic card installed. if not you have to be aware of the upgrade.

firstly you have to have a power supply that can give power to the new graphics card, if you opt for PCI express these usually have a secondar power connector and your power supply will need to have the connector for this.

also *********** board will have to have a slot that accepts your new graphics card.

check with your computer store to ensure you get the right one. and that your pc will work with it ok.

I hope this was helpful.

Having trouble upgrading to xfx radeon 5570 graphics card


1) Did you upgrade your power supply? The x300se was a low power graphics card. The new card needs at least a 400W power supply and that is what I find in the specs. However, the exact power needs depend on the rest of the specs for the computer (use a power supply calculator to get an estimate: www.thermaltake.outervision.com/ ). (Optical drive, hard drive, etc)
2) Did you uninstall the driver for the original card before removing it?
3) Check for updated drivers (newer than on the supplied card). Download and install those.

The original card was a low-profile card. Do you have enough space for this card in the box? (Similar question comes in with the power supply - make sure it fits in the case.) Also make sure that you are not getting overheating issues with the new graphics card. There are slot cooler fans and fans that can be mounted above all of the card slots. The best choice for your needs depends on the case and the temperature causing instability.

If you provide more details on where you are having trouble, I'll try to provide more assistance.

(at least this graphics card doesn't require a pci/e power connection to the PSU, as far as I knowm so that is one less thing to go wrong. Note: PSU are often rated by the max peak power that they can supply; it is the mean (average) power supplied to all devices that matters. Otherwise, a gaming session will pull too much power and shut the system down.)

if thats wat the specs say then thats most probably the max youve just bought one thats to powerfull, and y did you need so much power the most powerfull graphics card in the world needs a 750watt power surpply, your computer is probably not designed to have major upgrades, and by looking at the specs i can see that your computer well putting it simply is **** for upgrading the specs are **** (no offense intended) i suggest upgrading to a whole new computer if you want that sought of power and graphics

My Pc just shut down while i was playing a game. i unplugged my geforce 9600 gt's power and my pc worked again, but without graphics. what is wrong with my graphics card???


The problem that caused the PC to shut off is the GForce graphics card is drawing too much power and the switch mode power supply was overloaded and shut down.
Check the switch mode power supply's wattage, if it is around 300 to 400 watts, it maybe be too low. You most likely need to get a higher wattage switch mode power supply, especially if you added more RAM, disk drives, DVD drives etc. to your PC after the initial purchase of the PC.

Hp compaq d530 400 watt power supply


You will not find a power supply for this case. Why would you want to upgrade such an old computer? Get yourself a new one with amply power for your needs. If you are one that upgrades regularly, get a standard case with standard components that can be upgraded without the hassle of replacing proprietary form-factor compnents.

Upgrade graphics processor hp pavilion zv5034us


Honestly speaking, I recommend you to go for a New Notebook rather than changing the Motherboard since it is not possible to purchase another Motherboard for this Notebook with a better graphic card.

The actul Motherboard of your Notebook will cost you pretty more and I personally recommend you to go for a New Notebook with which you can get latest Graphic Card and hardware components.

You can find the list of parts available for this Notebook from HP Part Store from the link below :

http://h20141.www2.hp.com/hpparts/Search_Results.asp?mscssid=EJVUXR20AGCT8PMRJKPJXR6FSGX6C2W2

However, if you donot have any issues with the Notebook currently, go ahead working with it.

Hope this helps...

Upgrading motherboard


Dual graphic cards aka SLI require a SLI Power Supply. This is a good option if you want to start building a new system. Another option is just to get the new Nvidia 280 graphic card. Check out Tomshardware.com for a killer article on the latest graphic cards.

PC is dead


I assume you installed the new graphics card already. Did you check if your power supply could handle the increased power? If your power supply is rated at 350W or less, I'd upgrade to at least 400W.

Also, ensure that the graphics card, if it has a power connector, is connected properly to the power supply, and that in the process of installing it, you didn't accidentally remove any of the power connections to your motherboard.

The Green LED lets you know that it is receiving power from the wall, and that the problem lies in the computer somewhere.
