Currently I have a Compaq SR1103WM, which I am on right now. I have recently installed a Sparkle Geforce 9400 gt into the PCI slot, the card drivers will not install, I have had people tell me to update my motherboard drivers (whatever that is) or update my PSU. The PSU that is in the computer is rated at 250 watts, could the card not have enough power?
When try to install the drivers from the card cd, the installation fails, If I try to install them from either Nvidia or Sparkle's site, they also fail. When the installation fails the screen goes black with a flashing underscore on the top right of the screen, just like it has restarted. Does anyone know the problem? If it is the PSU could I get a new one without having to buy a new case or motherboard? I cant get a new computer because I simply don't have the money.
Solved! Go to Solution.

Did you disabled the on-board-video? Is the new GPU detected in the BIOS? That's a very slow CPU. Don't think you will get very far even with that new GPU. It is possible that your GPU may need an external 12V power source from the PSU to remain stable. The PCI slot may not provide sufficient current to run this card.
Need to try an AGP card, or buy another PC.

AGP is not an option because the computer doesn't have those ports, it just has PCI.
I can't get another computer because of money situations.
Later on I will try to find a CPU that matches the pins the socket has.
I found out that the card requires 300 watts while the system can only supply 250, tommorow I am getting a new one from a local computer store.
Would anyone know how to install a power supply? Would I need anything other than the power supply?

My bad...no AGP. The stock PSU has plenty of power to drive that GPU if it is located in an AGP slot. Each PCI slot is designed for up to 25W max. You can hook up a 1000W PSU, but the PCI slot will still be limited to 25W. Go back and re-read my post. Need to disable onboard video and check for detection in BIOS. If you cannot install the card with various drivers, then try another PCI card. There is no guarantee compatibility in the hardware business.
You are trying to upgrade a PC that will net you very little in performance gain. Put the $ in a piggy bank and start saving for another new PC. Really no need to pour more $ into a black hole.
Each installed PCI card must draw less than 25 watts of power. The total allowable maximum wattage for PCI cards is 150 watts. The PCI slots are limited to 25 watts power dissipation per the Peripheral Component Interconnect Specification 2.1.
Again, that motherboard may be at the borderline of putting out sufficient current to run that GPU. You can try another PCI slot. Sometimes, moving the GPU to a higher PCI slot will give it a little more juice due to the shorter electrical path to the PSU.
If you still insist on another PSU, then order this $38 Corsair from NewEgg.

The Graphics card has something that looks like a power plug for a fan on it, but the card has a giant heat sink and thus has no need for a fan, could this plug be to power the card? Also the card is on the top PCI plug!
The PSU is running about 5 times louder and hotter now that I installed the card.

That's a passively-cooled card (no fan). The small two pin connector is reserved for a GPU fan. Try another PCI slot. The OEM is getting quite old with a lot of dust bunnies inside. Any load will result in higher fan speed.
The giant GPU heatsink tells me that this GPU can come pretty close to drawing the full 25W from the PCI slot. A new PSU may help, but I suspect the root cause is the motherboard.

Sure...pic is good. Cheap way is to use a PCI card that doesn't draw close to the the limit supplied by the PCI slot. But you've already paid for the card. You could try another PSU from Staples. Get a full refund if it doesn't work.
The GPU may work okay if you have a good board. Remember that there is another powersupply on the motherboard to drive various components soldered to the board. If this powersupply has degraded over time, then you may have difficulty with that 9400 GT.
If you are local, then I can help you build a cheap PC. You still need to save about $200 for parts. The best and most logical solution is to save $ toward a new PC.

Sorry, the pictures were taken from my cell phone, I cant use a digital camera because of the card problem on the main computer![URL]http://i40.tinypic.com/k0rhqp.jpg[/URL]
On the pictures with the graphics card, you can see the heat sink covers a pci slot.
And if by local you mean Clermont, FL?

Get a pic of the fan header on the GPU. Disconnect the optical drive, floppy drive, 2nd hard drive, and modem/LAN card. This will give your PSU another 20-30W headroom if you suspect that the stock PSU is underpowered. Remove all video drivers. Shut down PC. Clear CMOS. Disconnect power cord from PSU. HIt the power switch to discharge the capacitors.
Reboot and see if you can install the video driver. No joy? Move the GPU to another PCI slot and retest.
Ahhh central FL. I used fly to Orlando and travel to Cocoa Beach to support shuttle launch at the KSC (mid 80s till 00). PM me with an e-mail account and I'll send you links when I see a good deal on RAM, MB, CPU, etc.... Some will be free after rebate.
How bad do you want that new PC? You should have enough $ for a new PC if you kill the cell subscription for 1/2 year....hehehehhh.
