Q. I am having random lockups. How do I fix this problem?
A. There are several factors that can contribute to system instability. Since the graphic card is always drawing to your screen, Windows will often report the graphics card or its drivers as the problematic device after a system error. In most cases, the problem is caused by another device or component in your system such as the motherboard, system memory, power supply or hard drive. Here are some tips to help you troubleshoot your computer.
Close unnecessary programs and processes in Windows XP and Vista.
Right- clicks a blank space on the Windows Taskbar and select Task Manager.
Click the Applications tab to view the list of active programs.
Click on any program listed in this window and click the End Task button.
Repeat until all programs have been closed.
The following steps are to close unnecessary processes in task manager:
Click the Processes tab to view the list of active processes.
Click the User Name column header to organize the processes by your login.
Click on any program listed next to your Windows login, other than EXPLORER.EXE and TASKMGR.EXE, then select the End Process button.
(Do not close processes running under SYSTEM, LOCAL SERVICE, or NETWORK SERVICE.)
Repeat the previous instructions until all programs/processes associated to your Windows Login are closed except for the following two:
TASKMGR.EXE
EXPLORER.EXE
DWM.EXE (Vista only)
If you have installed NVIDIA nTune please uninstall this utility for troubleshooting purposes through Windows Control Panel Add / Remove Programs.
Thereafter, close task manager and try to reproduce the problem.
Check and see if your motherboard chipset drivers are up to date. Since everything runs through your motherboard, the motherboard chipset drivers should be installed and up to date. Otherwise, this can lead to system instability. Here are the links to the most common motherboard chipset manufacturers:
AMD / ATI - www.amd.com
Intel - www.intel.com
NVIDIA - www.nvidia.com (for nForce Platform Processor only)
SiS - www.sis.com
Via - www.viaarena.com
Q.I just installed a new NVIDIA based graphics card in my PC to replace an older graphics card. I am not getting noticeably better performance when playing games. How can I improve performance on my PC?
A.If you have installed a Performance or Enthusiast class graphics card and your computer's frame rates have not dramatically increased, it could be caused by a number of factors. Please read the following guidelines to troubleshoot your performance issues:
-- Uninstall older display drivers - When replacing graphics cards, you should always first uninstall your previous cards display drivers. If they are left on a system, they may remain active and consume CPU resources which lower overall performance, especially when going from a non-NVIDIA based graphics card to an NVIDIA based graphics card. Please check that the drivers for your previous graphics cards have been completely removed from your system.
-- Software audio controller - Most PC's shipped today use an onboard sound controller for audio playback. These solutions use more CPU resources than a dedicated hardware sound card. Upgrading to a hardware PCI sound card can provide improved performance in 3d games.
-- External power - If your graphics card requires an external power source, verify that the cable from your PC's power supply is running into your graphics card. When the graphics card is not receiving enough power, it reverts to lower clock speeds to prevent your PC from locking up.
Motherboard chipset drivers - When installing a new operating system, the drivers for all of your components should be installed including your motherboard chipset drivers. If Windows is using standard drivers, it will not perform at the optimal level that your graphics card is capable of.
PCI Express vs. AGP vs. PCI - Before purchasing a new graphics card, inspect your system to find out what type of slots it supports for graphics cards. Many of the older PC's use an AGP slot to interface with a graphics card. Newer PC's have a PCI Express x16 slot for the graphics cards. Both of these slots are high bandwidth communications slots designed specifically for graphics cards however are not interchangeable with each other. Several budget older PC's do not offer support for AGP or PCI Express x16 graphics cards. This may require you to purchase a PCI graphics card. If this is the case, then it may be limiting the speed of your graphics card. A PCI graphics card operates at around 20% lower speed than an equivalent AGP or PCI Express x16 graphics card.
Q.What is the difference between DVI-I and DVI-D on NVIDIA based graphics cards?
A. Most current NVIDIA based graphics cards feature a Digital Video Interface (DVI) connector for connecting a digital flat panel LCD monitor or projector to the card. A DVI connector is characteristically colored white (as opposed to a VGA connector which is colored blue). For every graphics card that features a DVI connector, the number of pins and layout of the pins on the DVI connector will vary depending on what type of DVI connector is found on the graphics card. There are currently two prominent types of DVI connectors, DVI-I and DVI-D
DVI-D connector on a graphics card sends out a digital signal only, while a DVI-I connector, which carries both an analog and digital signal, can send out a digital signal (for digital displays such as flat panel LCD monitors) as well as analog signal (for older displays such as a CRT monitor) using a DVI to VGA adaptor. The graphics card shown in Figure 1 which shows a DVI-I connector contains more pins than the DVI-D connector shown in Figure 2. The extra pins on a DVI-I connector carry the analog signal which the DVI-D connector does not have.
NVIDIA based graphics cards which carry a DVI-I connector are fully compatible with flat panel LCD monitors which typically have DVI-D cables. The DVI-D cable will only read the digital signal from the DVI-I connector on the graphics card and ignore the analog signal. If your NVIDIA based graphics card features two video out connectors (ie VGA + DVI), it does not necessarily mean that it will support dual monitors at the same time. Some NVIDIA based graphics cards will look similar to Figure 2 which features a DVI-D connector as well as a VGA connector. These cards generally will only support a single display at a time, not dual monitors. The reason for having two different type of connectors is to allow you to connect either an analog or a digital display to your PC.
Q.Upon boot up of my computer, I get no video signal to my monitor and get only a black/blank screen. How can I resolve this?
A. If previously using an integrated video device on the computer, connect the monitor cable back to the port that you used to connect to. Boot up into the motherboard's BIOS settings, consulting your motherboard's documentation if necessary, to disable the integrated video card, save the settings, and then reboot with the monitor cable connected to your new video card.
Should that not work, try swapping out your system RAM and running each stick one slot at a time and one stick at a time.
Also, make sure that the power supply meets the minimum requirements of the video card. More important than the wattage will be how many Amps are available on the 12v power rail of the power supply. You can check this on the power supply unit itself by removing the side of the case. The label on the power supply will list the 3v, 5v, and 12v power rails. Add up the number of Amps listed next to any 12v rails listed and make sure that the total is greater than or equal to the minimum required listed on the side of your product box.
Q.I am having audio capture problem. How do I fix?
A.Please download file make correct audio setting. Download
Q.Why does the PCIe power adapter have two plugs at the end that plugs into the power supply?
A.Most newer power supplies now come with a dedicated 6 pin PCIe power connecter. If your power supply does not have one you must use the PCIe power adapter and connect both 4 pin molex power connections to your power supply. This will ensure a reliable flow of power to your graphics card and help stability.
Q.When I run a 3D application, the screen suddenly goes black ( I lose the monitor signal, but the computer doesn't lockup. How can I fix it?
A.Try going into Safe Mode and go to Control Panel / System. Remove all monitor devices listed and let Windows redetect the Monitor with it restart.
Try changing your refresh rate for the current display resolution and colour depth
Q. I am getting a CODE 10 Error-how can I fix this?
A. Code 10 means Windows didn't assign an IRQ to the device properly.
In device Manager, click on your display adapter ( click arrow next to Display Adapters ) and choose Properties.
Look at Resources and see if an Interrupt Request has been assigned to it.
If you are comfortable with opening your computer, you can try this.
Ground yourself by touching something metal before touching anything inside the computer and of course have it unplugged.
Disable your sound card and network card.
And while you are in there, make sure the video card is properly seated
Then turn on your computer and see if an IRQ has been assigned to the video card
If not remove the drives for the video card and reinstall them and reboot
If windows then assigns an IRQ to the video card, reinstall your card and make sure an IRQ has been assigned to it
Then reinstall the network and check it's IRQ
Hopefully allowing windows to deal with one device at a time will allow it to sort out the IRQ's and get everything running
Another thing to check, Windows XP should have ACPI IRQ Holder for PCI Steering
This allows more than one device to use the same IRQ
If this is missing that could be a season that an IRQ was not assigned ( You have too many devices and not enough IRQ'S
To check if PCI Steering is on go to system information it should be listed under accessories in your start/ programs menu
Click on arrow next to hardware resources than click on IRQ's
You will see list if IRQ's and what device they are assigned to
Make sure you have ACPI IRQ Holder for PCI Steeling listed. It can be listed more than one time
Q. Where can I download VGA BIOS so that I may flash my video card
A. At the moments, we do not offer video BIOS for download. Zogis will not be responsible for incorrectly flashed BIOS as it will void manufacture warranty
Q. What size power supply do you suggest for running NVIDIA GPU?
A. While some cards only requires 300 watt power supplies other require as much as 480 watts. Please check the product page of the card you are interested in to verify its requirement
Q. Is there a maximum resolution when using the TV out function?
A. The maximum output is 1024x768.
Q. Why my screen scrambled after the new driver installed?
A. The monitor you are using is not synchronizing with the display adapter. Lower the display adapter REFRESH rate. In case the refresh rate is set to minimum and the monitor is still not working, change the monitor type configuration in Windows
