    Unhappy Troubleshooting 7800 GTX

    Hi guys - hope someone can help - cause I can't play anything at the moment and the windows drivers make my screen look funny.

    Had the machine together a couple of weeks now - wife wanted some cheapo software package on the machine, so I loaded it on. Problems! The display is set to display 4 colours and a very low res and there are no options to change. I tried to fix it.

    When I use the XFX Drivers CD for my card the machine restarts after installation and still displays in 4 colours at very low res. There are no other choices available. I have tried the new NVIDIA drivers but these produce the same result. I also cannot install Direct X 9 from the CD - it freezes while trying to execute. I have tried removing the NVIDIA drivers and going from scratch. Also done a system restore.

    These problems occurred after I loaded software onto my machine and which I have since removed. Nothing doing. Can you advise a course of action please? The windows drivers allow the card to work in 32 bit and 1280 x 1024 so it ain't the monitor.

    Any help appreciated. Thanks

    You are going to have to do a clean out, check through the registry for any of the cheapo software, and clean. DL driver cleaner, install, remove the nvidia drivers from add-remove, reboot safe mode, run driver cleaner/clean nvidia graphics drivers, reboot, install drivers.

    Also run/dxdiag/display run the tests you see

    Thanks for your reply - I have checked the registry and cannot find any trace of the software. I have also tried removing the NVIDIA drivers and reloading them but upon reboot the problem is still there.

    I don't think it is a hardware issue as the card is functioning fine with generic windows drivers. I have contacted XFX and waiting for a reply sometime tomorrow. I am going to get IOLO System Mechanic 6 and do a detailed system/ registry clean-up to see if this will help me resolve.

    UPDATE: Having downloaded System Mechanic I cannot get it to run setup.

    Any other thoughts welcome.

    Un-installing drivers, be it sound/graphics/chipset from add-remove is not sufficient, driver cleaner does that job, give it a try, it is worth a shot. Have you ran a virus scan? If you cant get one to install, try one of the free ones, housecall, mcafee, I am sure kaspersky also did one

    Might help if you told us what the machine is? Hardware? OS?

    Hi - It is a self build.

    Mobo is an ASUS AN8-E and the OS is XP Home SP1

    XFX 7800 GTX 256Mb Gamer Edition

    2.5 Gb RAM, 120 Gb HDD


    I am scanning the system with Norton as I type. I have downloaded, installed and used Driver Cleaner 3. Once the scan has finished I will reboot and try a fresh driver install. Will post with results.

    Thnaks for the tips.

    Cheers

    Update

    Ran Norton - nothing found. So deleted Nvidia Drivers in Add/remove

    Ran Driver Cleaner 3 Pro - cleaned.

    Ran System Mechanic 6 - I am now able to install it after running Driver Cleaner. Cleaned system through

    Rebooted

    Card has no drivers listed. Cool.

    Inserted XFX CD and loaded up drivers upon restart the problem still exists. I am thinking I might have to reload windows, as maybe the software damaged the windows install, not sure if this is possible - what do you guys think?

    Could try and repair - but do not know the commands I have to use to try and resolve.

    Appreciate your thoughts on this.

    I would go to the nvidia site and download the latest drivers.

    http://www.nvidia.com/object/winxp_2k_81.98.html

    Can you tell us wwhich software package it was because there may be known issues?

    I have downloaded the drivers (.98) I also have the .95 version as well have tried them but no joy. Thanks for posting the link iranu.

    The software package is 'Greeting Card Maker' by Cosmi. My wife was going to use it.

    If I resolve this through XFX I will post and let you all know how.

    There is a similar thread here http://forums.hexus.net/showthread.php?t=64167 but with an xfx 6600gt. Sounds like it may well be a hardware problem. I'd look to rma the card.

    Have you tried reseting your bios? I know its unlikely, but it is possible for software in windows to modify bios' these days.

    Thanks for sugestion. Which BIOS? Card or Mobo?

    If Mobo is it just a case of clearing CMOS (remove batt/ move jumper)?

    I am not sure how to do anything on BIOS.

    Thanks

    I was referring to the motherboard BIOS but for sure you might as well check the gfx card one as well (I'm not used to them having BIOSes!)

    First I would just try going into the BIOS options (F2 on start up or similar) and there might be an option for 'reset to defaults'. Try this first before resorting to a hard reset (which is more designed for when your computer won't boot).

    If you do need to hard reset check your motherboard manual for how to do it - you will probably have a jumper that can do it, but if you can't find it, removing the battery for longer than 5 seconds usually does it.

    For the gfx card you may be able to download a BIOS from the manufacturer - you will probably need to create a boot floppy to flash the BIOS this way though. HOWEVER - do check with the manufacturer first regarding warrenty - if they provide a BIOS it should be within the warrenty to update/reflash it, but check the details of the warrenty first.

    Nvidia Customer Help Reply

    I am in work so not tried this yet - sounds like twaddle to me!

    But here it is in all it's glory the Nvidia reply to my query re the fault/ problem. Waited two days for that, but I would have thought that the options should be there automatically (with drivers) as windows detects the cards capabilities without the drivers.

    kalniel - again thanks for your help. Black.
