Video Card issues: fried?

I have a Compaq Presario SR5160AN Desktop PC, which has a Nvidia GeForce 8400GS Video Card. I have changed the OS from WIndows Vista to XP Professional, since I use it mainly for gaming, and Vista uses too much of the computer's RAM. Recently, while playing games on this computer, after about 10 minutes of gameplay, the screen goes a multitude of colours at the same time (little square blocks of many colours, covering the entire screen), the sound seems stuck on an infinite loop of less than a second (a-a-a-a-a-a really quickly), and I need to restart my comp in order to do anything. I had a quick read through some of the solutions for other similar issues, and from there it seems that my Video Card is shot, But since no one's really explained 'what' happens to their computer (I suppose it's hard to explain exactly what is happening on-screen without thinking long and hard about 'how' to explain it) I thought I'd ask myself.
If the card being shot is the case, would a Nvidia GeForce 9800GT PCI-E 2.0 1GB DDR3 Video Card be more suitable? I have ordered one, and I'm hoping it will be a bit better than the 8400GS.
Thanks for any solutions that can be provided.

    The card I would presume has a fan, Since it was shipped directly with the computer as I bought it. I have owned the computer for Around a year, and all the Drivers/Service Packs etc are all up to date.

    Is there a way to tell if it's the card itself or the PCI-e slot? I'm not much of a techie, but I could get someone to take a look for me if it's not something easily visible. I don't want to go paying out all this money for a new card if it's the PCI-e slot ._.

Yes, it sounds like either the video card is bad, or the PCI-e slot on the MB is bad. If you do indeed have a PCI-Express x16 slot on the MB, than yes a 9800 series should do fine provided your power supply is up to the requirments needed for the card.

Why my hp is not able to run need for speed most wanted

From what I ca see you need to upgrade your video card. The software's minimum requirement for NVidia is a GeForce 8800GT or higher. The minimum for an ATI card is RADEON 3870. Your machine comes with wither an NVidia 8400GS or an ATI RADEON 2400.

Installed GEForce NVidia 8400GS graphic card but no video output. Onboard and other video cards will work. The 8400GS will work in other desktops correctly. Any help would be graet!

Assuming that you have installed the drivers for your new board, go into Control Panel, select Device manager and Display Adapters.
Dissable the onboard adapter and enable the NVidia card.

I have a dell 20" LCD monitor. But Presario S4000V doesn't fit for that monitor. Please let me know what can i do. Change "Video card"? thanks

Have you tried changing the Resolution settings to "Recommended"? If so, then you may have to purchase a newer Video Card. Look-up your motherboard 1st, then go by the Recommendations of the motherboards BRAND and Chipset of Video Cards. If you have nVidia Chipset, get GeForce or nVidia card, VIA, SiS work fine w/ these (nVidia Chipsets) Video Cards. But, if the motherboard is of Intel Manuf, you will want the ATI card. Get at least a 256MB Memory card(512MB is better) and read-up on the cards resolution to make sure it fits your screen size/dimensions. Good Luck. To find out your motherboard type/brand, dwnld. CPU-Z for free online. It will tell you about your CPU, Motherboard, Memory, and alot more.

Problems with 8400GS graphics card

First, you need to be sure you have installed the correct drivers for the card that corresponds to your OS.

Second, you need to go into the control panel (assuming you are running Windows of course) and tell the computer you now have a new graphics card installed and to use it instead of the default one detected when the OS was installed.

Reattach the monitor to the GeForce card and reboot. All should be OK.

I have quite a few d530-SFF systems. They have the ''standard PCI'' slot ''carrier'' that plugs into 1 of the 3 PCI slots on the M/B and has 2 full-size PCI slots. I installed a PNY Nvidia GeForce 8400GS...

I checked the specs on the video card thinking it must be PCI-e and not old style PCI but in fact there is an old style PCI meant for just what you are trying to do. The problem is the memory at 512meg plus the GPU put your power requirements at 300w and I bet you have at best 185w in those units so they won't even start and you won't be able to cram the bigger power supply in there. Go with a card that has lower specs and 64 - 128 ram and you should be ok. Just check the power req. JC

NVIDIA GeForce 8400GS dual monitor problem

In this case too much ground on your TV. Going through to your S-Video input. I have encounter with this problem but I fix it. Most likely the another problem is the compatibility with your Motherboard and your New VGAPCI-E Card 8400GS, this VGA Card are likely known or have another connection to another Monitor or TV Devices.
Here's what you do, use your Utility Disk that have INF software programs that support your Motherboard from any plug-in devices like PCI-E Card. That INF program provide assistance to accelerate some resolution or pixel graphics on your System and also use DirectX 9.0C version to test the resolution that can give you satisfaction to use dual view on your PC. hope this might help you. Good luck!
