What does power down pc and plug in cabkes for gpus mean, even though they are already plugged in bad card?


Added a new graphics card? Today, high-end gaming graphic cards (GPUs) need separate power from the computer's power supply; they take more power than the motherboard can give them through the connector under the card. Your power supply should have separate connectors that match what's on the new video board.

Shut your computer down, pull the plug, open it up, and connect the power supply to the card, and then you'll be fine.

Ugrade Lenovo 8113 to GeForce 8500GT 512 -Problems?


Not a compatibility issues per se, but their could be a Driver conflict.

Install the Drivers FIRST, then power down, computer unplugged from power, observe Anti-Static precautions, and install the graphics card.

Plug the monitor into the graphics card, plug the computer into power, WAIT 1 minute, turn the computer on.

(The drivers are on the installation CD that comes with the Nvidia GeForce 8500GT graphics card. Just install the CD, and load the software. The drivers will automatically be loaded)

If you install a device first, (Such as a graphics card), Windows will break it's neck trying to find suitable drivers.
Windows will match up one of it's thousands of generic drivers.

Then you come along, and install THE drivers.

Driver conflict.
Windows: "Which drivers do I use? These or THESE?"

If you have already installed the graphics card, then powered the computer up, and installed the drivers, I suggest you do this;

Computer off, and unplugged from power. Open the computer case.
(I prefer to remove all cables to the computer, and lay it on it's side on a clean towel, on a table)

Observe Anti-Static precautions.

[Anti-Static Precautions:

Your body carries Static electricity.
Static WILL fry out (Short Circuit) the hardware components inside a computer.

You may not even see it, or feel it.

Computer on a table, computer unplugged from power, computer case open.

TOUCH the metal frame of the open computer case, BEFORE you reach inside the computer, or take a device out of it's anti-static bag.

Should you get up in the middle of working on your computer, and leave, upon your return Touch the metal frame again ]

Remove the GeForce 8500GT.
Plug the monitor into the Integrated Graphics of the motherboard.
(VGA port

http://en.wikipedia.org/wiki/VGA_connector

Press the Power On button in, and hold it in.
Hold it in for a count of Five seconds.
(And I mean at least Five. Count 1001, 1002, 1003, 1004, 1005)

Let go of the Power On button.
Do this procedure two more times.

What you are doing is clearing CMOS Error Codes, and resetting BIOS back to the factory default settings.
One of which is Integrated Graphics.

Computer case open, cables plugged back in, computer in normal position.
Plug the computer back into power.
WAIT 1 minute, turn the computer on.

When Windows has fully loaded, go to Start>Control Panel>Add/Remove Programs.

Remove anything you see associated with the GeForce 8500GT.
(DO NOT remove anything in the Windows files. It's a separate section you have to go into anyway, but thought I would warn you in advance, just in case)

Restart the computer. (Start>Turn Off Computer>Restart)

Once Windows has fully loaded again, install the software off of the CD disk, that comes with the GeForce 8500GT graphics card.

If you are asked to restart your computer - No.
Close all windows, go back to your desktop screen.
Shut your computer down normally.
(Start>Turn Off Computer>Turn Off)

Unplug your computer from power. Observe Anti-static precautions. Install the GeForce 8500GT.
Plug the monitor into the graphics card.
Plug the computer into power.
Wait 1 minute, turn the computer on.

Everything works okay, close the computer case.

1) No. The switch color should have been Green

2) No Signal on the monitor, indicates the monitor is not receiving a Video Signal from the computer.

A) Could be due to a faulty monitor cable.
Monitor cable is used on a working computer for a test,
Or,
working computer's monitor cable is used on the Advent for a test.

B) Could be due to the graphics 'engine' on the motherboard, or on the graphics card is bad.

[Graphics 'engine'.
GPU
Graphics Processing Unit.

http://en.wikipedia.org/wiki/GPU ]

If the computer is using Integrated Graphics, the GPU is on the motherboard.

(Integrated Graphics is also referred to as OnBoard Graphics. Meaning On the motherBoard)

You will know if it's Integrated Graphics, because the monitor cable will be plugged into the VGA connector, on the motherboard

http://en.wikipedia.org/wiki/VGA_connector

Since you indicate an adapter was included, to adapt to a different port (Connector), it could be a VGA to DVI adapter, or a DVI to VGA adapter.

Your monitor may just have a VGA connector on the monitor cable.
Hence you would use a female VGA to Male DVI adapter.

Your monitor may be an LCD flat screen monitor, and has a DVI connector on the monitor cable.
Hence you would use a female DVI to Male VGA adapter.

DVI
Digital Visual Interface

http://en.wikipedia.org/wiki/Digital_Visual_Interface

VGA monitors are Analog.
LCD monitors are Digital.

A computer puts out a digital signal.

If a VGA monitor is used, the computer has to alter the Digital signal to an Analog one.
This slows down the video signal.

If your monitor (In any case. Not just this one), is an LCD flat screen monitor, it is best to use a DVI monitor cable, and plug into a DVI port on the computer, if available.

If your monitor is a VGA (CRT. Cathode Ray Tube), monitor, and you have a DVI connection on your computer, using the adapter will do you no good.

The adapter just uses the contact pins for VGA, that are present in that DVI adapter, and hence the DVI connection on the computer.

You're still just getting an Analog VGA signal.

Example of a female VGA to male DVI adapter,

http://www.directron.com/dvi.html

If the Integrated Graphics are suspected to be bad, a graphics card is used in the appropriate expansion slot, for a test.

If the graphics work then, the graphics card is left in service.

After I test the monitor cable my next procedure is to suspect the Power On switch, or the Power Supply, and go to the graphics next.

The reasoning is that Power Supply failure, is the number one cause of computer failure.
The next is the Power On switch, then Electrolytic Capacitors used on the motherboard.

(Specifically, any Electrolytic Capacitors used in the motherboard Voltage Regulator Circuit)

If the Power On switch is bypassed, the diagnosis will reveal if the problem is the switch, or Power Supply.

Bypass the Power On switch, and the Power Supply comes on?
Problem is the Power On switch.

[One Power On switch I have found to fit a lot of computers. The Power On switch goes into the plastic Power On button,

http://www.directron.com/atxswitch.html ]

Bypass the Power On switch, and the Power Supply does Not come on?
The problem is the Power Supply.

The Power On switch is bypassed using a jumper wire, from the green Soft Power On wire, to ANY black Ground wire. The contact made is a brief momentary one.

The jumper wire is used at the back, of the 20, or 24-pin ATX main power cable connector.

When you say you tested the other components, did you test the graphics card in particular on another computer?

If so, and if it worked, you can try clearing the CMOS. There should be an easily identifiable switch or set of pins with a jumper. With the power cable unplugged, set the switch or move the jumper into the clearing position, leave for about 30 seconds, then move it back into position (important! do *not* power on the system while the jumper or switch is in the reset/clear position). Try booting up the system again.

If it now has a picture, you will probably need to enter the BIOS and, at the least, make a basic change such as setting the first boot device (defaults to the cd/dvd-drive, then the primary-channel+master hard drive).

If you still have no picture, and you are using on-board graphics only, then there is a chance that the on-board graphics chip may have died.

To test this, you can put a graphics card into the system (I recommend a cheap, second hand one that you know is working, in case the motherboard ends up damaging the card), repeat the CMOS clearing process, and then try booting up the system with the monitor plugged into the graphics card.

If you get a picture, there's a good chance the on-board graphics have died. You'll want to go disable the chip to prevent it from causing any further problems by finding it under the 'integrated peripherals' section of your BIOS. If it's not located there, search for an option for the 'primary graphics adaptor', and change it from IGP to PCI-E. Then find any option for 'vga memory share size', and see if you can set that to 0mb. If it is the model with the 2400XT with its own 256mb memory, you'll need to find an option to disable it entirely.

Please post a followup if none of the above was able to help you, with clarification if possible as to what you're using and have tried, and I'll see if I can help further.

ASAP! Power Problems. Please Help!


try replacing the cable first, or try a diifferent monitor, otherwise open the case and look for a card that has the vga(monitor plug) on it-but your existing one may be built in to the MOBO in which case you will have to disable that driver, then pop in your graphics card in an empty pci slot and download a new driver
