Question about Nvidia GeForce 8800 GT 512MB Graphic Card

1 Answer

No Signal I was using my computer the other night when my cat knocked out the power to my computer. when i restarted the computer my monitor was not receiving a signal. i tried a different monitior to see if it was my monitor that was the problem, but no signal was still being sent to that monitor either. Can this problem be fixed or do i have to replace a part if? so which part? I have a Gigabyte 8800 512 MB, Asus motherboard, AMD Quad core processor, 900 watt PS, and overheating isnt the problem my computer was at a constant 86 degrees.

    hI,

    Can you tell if the computer is actually running ? Usually you should see the hard disk like (a cylinder icon) flashing during the boot process.

Just out of curiosity confirm that the power switch is set to 115/120 and not 230/240 (assuming you are the states)
Try These please
1- if the motherboard has a built in video card, plug the monitor unto that to test .
2- remove the video card from its slot then reseat it, then power on system
3- remove the memory and reseat, then piower on system

    ok try this

    take all the memory sticks out, and power on

    the system should beep, that will confirm if *********** board is doing doing its system tests.



    Secondly remove all devices on the motherboard just leaving the barebones, video and motherboard.

    Since you are already at it you could also reseat the processor.

    Hope this helps you to narrow down the problem

Wont start up


Check physical connections first, check monitor cable if securely plugged in and then check power light of monitor. If power light on monitor is amber or yellow it means that monitor is not getting a signal from cpu/ tower. Try to do a power drain on the computer, remove power cable at the back of the computer and then press and hold the power button for 10 secs, after that plug in power cable again and restart the computer.Check if there is any connection if not then try to use another monitor, a known good one. If you get a video from another monitor it means monitor is already defective.

No signal with acer moniter


Check your power settings on your PC (Start Button ---> Settings ---> Control Panel ---> Power Options)

Under the "Power Schemes" tab you will find the dialogue "Turn off monitor:" and then your choice. The power option refers to the SIGNAL sent to the monitor, not the actual monitors power-source itelf (although some can control both). It will simply stop sending a signal to the monitor and "put it to sleep"

Change the setting to what is appropriate for your use, and you should be set!

Hope this helps!

I have a Princeon Monitor attached to a dell computer- been using it for about 2 years with no problem. I usually leave both computer and monitor open at night. Last night, there was an electrical storm...


Mmmm not a good thing. Ive had this happen to me before. Knocked out my COMPUTER, MONITOR, AND TV! Well it could have shorted your monitor, you can get it fixed, but mind as well pay for a new one. As long as the one you have now is not really that expensive, but you could probably get it fixed for around 80$.. I wouldnt recommend it to be a "Do it yourself job" I would call some tv repair shops.

My monitor says no signal


You'll need to check the cable connections and the computer that it is attached to. The monitor may be going into standby mode because the computer went into Suspended/Hibernate mode. Try restarting the computer. If you're unable to do this, try a hard power off and then try to turn it back on.

Monitor goes to white at cpu shutdown


The problem is in the "soft switch" technology: On some of Sylvania's newer monitors they have incorporated what is called "soft switch" technology. This allows your ATX power supplied computer to turn your monitor on and off using it?s software controls. Therefore, your monitor?s light will always stay on blinking even when your computer is off. The monitor in normal operation consumes about 80W of power; in the "OFF" state it will be reduced below 8W. The "OFF" mode of the monitor can be controlled by the PC input signal or by pushing the soft-power button to disable the PC signal control for manually turning off the monitor screen. Thus, when the monitor is in soft-power "OFF" mode it still consumes a very small amount of power. For the purpose of making it noticeable to the user that the monitor is in soft-power "OFF" mode, we designed the power indicator to provide for a slow blinking signal (every 2 seconds). If you need to totally turn off the power, then the power cord would have to be unplugged. The same is true of the PC itself, but the PC does not provide for notification while in "OFF" mode. Your monitor looks like it may be in need of repair, contact info: PTI Technologies Inc. 7372 Doig Dr. Garden Grove, Ca 92841 Phone: 714-799-3899 Fax: 714-379-6290 Hours: Mon - Fri 8:00am to 6:00pm PST
