I just changed my desktop graphics card to 1GB and I have driven it. When I connect it to a particular monitor it render things slowly, but on another monitor I used it rendered well? What might be the cause please?
Heres a few guidlines for troubleshooting your problem hopefully ...
1.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.
2.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 imrpoved performance in 3d games.
3.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.
