    Have you used the nVidia control panel to check the temperature of the card? Have you verified that your cooling fan on the card is still running? It sounds like the card is heating up and shutting down. I would be surprised if it were clogged with dust after only 5 months.

Your card is probably overheating. the alphadog editon has an extremly small cooling for the gpu. try cleaning it with a caned air spray and check the NVIDIA control panel to see the temp. of the GPU if the problem is solved try running a game benchmark to see if that works.

8800gt wont boot my 8800gtx will so it not power related please help


Hello there, I am the Expert that will be helping you today. My name is damnor01.

Welcome to Fixya.
As your 8800GTX boots fine and your 8800GT does not boot one would say that your 8800GT is faulty.

How faulty one does not know, does the fan spin? If so then there is some life left in it.
A technician might replace the capacitors for a fee, this may get it working again.

There is not much else on can do but give it to a computer technician to try and repair it.

When I connect the moniter to the graphic card geforce 6200 it will not show a display at all. connection to the computer using the regular connection it shows


On both the Graphics card and the monitor, the blue connector is a 15 pin DSub VGA video and the white connector is a DVI video.
With the monitor it should default to the 15pin DSub video input.
If you want to use the DVI video input you need to configure the monitor to use the DVI video input. DVI to DVI give the best picture quality.
If you want to go from 15pin DSub to DVI you need a converter cable.
Try conviguring the monitor for a DVI video input.

Monitor shows no signal at loading of desk top, works fine through boot up


no signal means the cable is not connected to the video adapter,

if your motherboard has a built-im videocard plug your monitor to the built-in video then change the right settings at the bios

hope this thing helps

VGA connection works, DVI does not


Everything seems perfectly normal...

When you connect the computer to the monitor via an analog VGA cable, you get signal on the analog input.
When you connect them via a DVI cable, you feed the monitor's DIGITAL input, so the monitor doesn't get any signal on it's analog input, and informs you about it.
You have to select the digital input from the monitor's On Screen Menu, and then start the computer up - you should see the picture OK.
Also remember to set the display resolution on your computer to match the optimum (native) resolution of your monitor - this will give you optimum picture quality. In case of VA712B it will be 1280x1024.
Good luck and please come back with a testimonial if helped.

Pull out the graphics card & RAM chips. Give their contact points a good cleaning and replace hem. Also check to see that all cables are snug tight. Finally remove the Monitor cord fro its slot at the back of the CPU and remove all dust and check if any pins are loose. See that the monitor plug is firmly placed..................sodeep

Freezes while playing WOW or graphics go berserk.


Thats odd. Try cleaing out the cooling fins with compressed air to get ou the dust. Take out the card and put it back in.  Have you tried updating the driver? try this stuff and see if it helps. I hope it does. cobrasdh

No signal on first boot


This would usually indicate that there is a problem that is causing your computer to not boot correctly all of the time. What you have described could be many different problems and without more information I cannot say which one it is.

1. Hard drive. I have ran into Hard Drives that for some reason do not start up correctly right away when you put power to them. This can cause the initial startup to hang possibly indefinitely.
2. Video Card. Something probably firmware is causing your video card to not start up properly when power is first applied.
3. PSU. The power supply could cause similar problems if it cannot supply enough power because the highest power draw is when you first turn on the computer. When you push the reset button the power is already being supplied to most of the components and the ones that did not have enough power to start properly before can do so now.
4. CPU. If the CPU has some minor problems it can cause similar problems. In any case to fix it you can try clocking down the CPU but you are better off replacing it.
5. RAM. I have had similar problems with RAM. Clocking down the RAM fixed the issue.
6. Settings in BIOS. I would check to make sure the setting for init display on boot is set for PCI-e.

Hi, if you have got the drivers for this v/card then load them while you have your present one in place, if you dont have the drivers then go to the manufacturers website and get them . when you have loaded the drivers then check if you need to enable any changes in your bios. Change the card and if it is functional then you should have solved your problem. A card that advanced needs drivers far greater than you would find in XP. Regards mistyman
