Question about XFX GeForce FX 6800 (256 MB) Graphic Card

2 Answers

Monitor goes blank after showing XP logo screen (black screen with the xp logo right after boot up screens)

How is it going? I really do hope you can provide me with some insight :) I used to have a ati 9200se card and my computer worked perfectly for 2 years. 2 weeks ago, I bought a Geforce 6800 xfx (agp) 256mb card. I installed it; drivers as well. Then connected to my mointor using the dvi to vga adapter. And worked fine. And it did work fine for 3 days. Then I had to open up my cpu case; remove heatsink; check processor etc. And now whenever I boot up the computer........its shows the first boot up screen as normal (screen which says 3.00ghz, 1.5gb ram etc xp or recovery console etc). Then it show the next normal screen........the black screen with XP logo. AND THEN........... THE monitor goes dead. Says "monitor working fine; check your connection cable or computer". This keeps on happening every single time. Could you please help me. My email id is: (if you need) THANKS BOSS.

    Hey......that was extremely fast reply.

    Thank you.

    While you typing reply, I was working on the safe mode. And its not all bad news.

    Safe mode works fine. The resolution was already the lowest = 800*600. I changed 32 bit to 16 bit. The DPI is 96 which i did not change. The monitor refresh rate etc are all greyed out. Nothing can be changed there.

    Then finally I reduced hardware acceleration a bit. Then restarted in normal mode.


    Everything good up to xp logo...then monitor goes blank!!

    Now the onboard video part:
    I have onboard video. But if I plug in to that output............NOTHING...and absolutely NOTHING shows up. Not even the initial boot up screens. I remember......i have tried that before just for fun. But onboard video has never worked.

    BRIAN ZEF Apr 28, 2007 I did the same in Enable VGA mode.

    Resolution was already 640*480 (and it even gave a notification that the display settings are very low). The other thing was 8 bit.
    Then 96 DPI and the monitor resolution was 60Hz.

    So there was nothing really to change.

    In any case.........important thing.

    WHILE I WAS LOOKING OVER THESE SETTINGS, THE MONITOR TURNED OFF (in this vga mode). As always, the computer was running; but not the monitor

    What the heck?

    Help.................... :(

    Hope to get a reply tomorrow. Thanks man.

    hey..thanks babb comp. has another serious problem too. I didn't mention it 'coz that was not connected to this problem and I didn't want to complicate the scenario.

    Thing is a heat sink/thermal paste related problem. Speedfan shows temp of 85 to 90 etc. Tomorrow I am buying artic silver 5 and am gonna apply. In the current situation, the computer won't stay up for more than 2 mins (EVEN WITHOUT THE DISPLAY PROBLEM).

    Now back to our problem.........I changed the video card with my old ati 9200se. And it works the problem has to be with the new card's drivers, as you say.

    Once I apply the paste tomorrow, i will try your method (of uninstalling the adapter and resinstalling drivers).

    Meanwhile......please tell me what you meant by " there a vga connector on the monitor?"
    I have tried this computer with two different monitors and both show the display problem (with the new card). One of the mointors has a slot in to which the monitor cable goes (from where the cable can be removed). It is a VGA slot (infact both monitors use VGA cables). However, the card itself used DVI and I have the DVI to VGA adapter.

    Hope to hear more from you (and as I said I will be posting back after applying the paste).


    BRIAN ZEF May 04, 2007

    Hey.......babb. I'm back again.

    I fixed the thermal paste problem. Now back to video card thingy.

    I installed the latest nvidia drivers and there is QUICK RESULT. Computer gets past the initial screen and I can work for a long time without a problem.

    But once in a while (during game play or not), the monitor says "switching off power" and it shuts down. Computer is still running. I then have to manually press the restart button and....then comp. boots up and everything is normal for a stretch of time. Later same thing happens.

    What do you think BABB?

    I have a toshiba Sattelite laptop. I started running a dual monitor and now the secondary monitor is the only one working. When I try to identify it it says the external monitor is #1. I have gone to the setting under properties. Changed it, tried Fn f9 - still nothing - Got any ideas

    i have the same problem jus after the windows xp logo it blacks out, i have even bought another monitor and still the same problem.

    Could have had some virus had a add that kept poping up called spyware guard 2008 could not get rid of it. Cpu was very slow also. Bought some soft ware to try and clean up the system but it would just lock up after running for 5 or 10 min. Decided to try a system restore and now after the window XP logo the screen just goes black.

    I have a Sapphire 7970 that starts to load windows, gets to the splash screen with the windows logo, blanks out but you can tell it is still booting windows cause the hd light still is working and you can hear the Windows bootup music, even after the monitor goes black. I installed another 7970 and everything works fine.

    Thanks Lonnie

There are different reasons why this might happen. Let's try some. 1.) Does your board have an onboard video card, cause if it does, then XP might be using that as the primary monitor. TRy plugging into the onboard video when you start up! If that works then you need to disable the onboard video.(try disabling it in bios!) if not then 2.)When booting at the select xp or recovery console, press F8. You'll get the menu with safe mode and what not. Go down to Enable VGA Mode then press enter. If that works, go to display settings and lower your resolution then restart. But usually when this happens your monitor says "Out of Range" but u can still try Well if that doesn't work, tell me more! Regards, Armando

    Don't go to safe mode, safe mode doesn't load the VGA drivers. Look for Enable VGA mode, it loads the driver but at the minimum, then you can set it properly!

    Armando Babb Apr 28, 2007

    Well lower the resoultion in Enable VGA mode!!

  • Armando  Babb
    Armando Babb Apr 29, 2007

    Well, the only other thing i can say is a last resort technique! While in enable VGA mode, go to device manager and uninstall the display adapter(video card)! When u reboot in normal mode, the drivers will automatically re-install (you might need the driver / cd) and hopefully you will be able to adjust settings, try to see if you can get the latest driver for your card!! Try that and see if that helps!!

    Hey another thought! Quick question is there a regualar VGA connector on the monitor????

  • Armando  Babb
    Armando Babb Apr 30, 2007

    Sorry about that, what i meant was if there was a VGA connector(as opposed to DVI) on your video card! But regardless I still think re-installing the drivers might work!

Been following this for a while. seems that this problem stretches across many types of display. I have onchip vid display. have DVI and VGA. VGA (2nd) boots up first then i usually have to hit properties and enable "digital display" instead of "monitor". lately (today) it was just the 2nd monitor. My VGA. I tried disconnecting so that the DVI would boot up, nope. switched my VGA cord to my primary (larger) monitor and DVI to the smaller secondary. works like a charm. I think that if you are trying to run DVI for a higher res monitor the system looks to the VGA? seems to be a common thread since alot of people will want the larger higher res monitor to be the Primary, but probably most drivers will look to VGA on startup.

The splash screen with the LG Flatron logo is the monitor's splash screen not the PCs.
The machine is NOT booting up the splash screen is the monitor coming on.
Remove the 1Gb stick an see if the machine performs normally.
If it does then power it off, remove the power cord and CAREFULLY reinstall the new stick.
If it fails to boot you may have a defective memory module.
If the machine fails to boot with the new stick removed make sure you have the original memory seated properly and all cables securely attached

Monitor displays breifly then goes to blank screen

If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.

Monitor goes standby after boot

Look the problem it may not your monitor it's your windows XP. Let me guess you have a VGA/Svideo card. From prior experience I can tell you that dual output Nvidia cards will default to Svideo first, and then "adjust" your windows settings to do so every time even if a VGA monitor is re-connected (HIGHLY ANNOYING). So if the last thing you see before nothing is the Windows XP boot screen, here's how to fix it. Boot to safe mode uninstall your video driver, reboot then reinstall. You can substitute a system restore for uninstalling your drivers if you can remember when the monitor was last working. This really really pissed me off when it happened to me.
