    Hello,

    I was just using my PC last night surfing the internet and doing some other things, but then my screen just went blank and it popped up saying no DVI connection or whatever. My PC still had power and all the fans were going and everything seemed like it had power. My pC has done this before but it was because my 8800GT got to hot and overheated. So I checked the cables and everything was tight so then I shut of my PC and waited a little while and turned it back on and got nothing not even the bios/bootup screen but everything had power and all my fans were running including the one on my 8800GT. Just nothing on my screen. So I turned it off again took off the side of my case and checked everything in there and everything was tight. So then I just left it off overnight and this morning tried again but still got nothing just power. So I decided to unplug everything and have only my memory and hard drive(s) plugged in and my Graphics card and tried just that and I still got nothing just power to my graphics card fan, PSU, and the CPU/heatsink fan. So I don't know what could be the problem. Do you think my graphics card could have gone bad and if so how do I switch back to my on board graphics, or if not what else could be the problem.


    Thanks,

    To switch to the integrated graphics, remove the video card from the computer and connect the monitor to the motherboard's port.

    Hey,

    Thanks for the info anyways I left everything unplugged for the day about 7 or 8 hours including the Power cord so only thing plugged in was the memory, hard drive(s) and Graphics Card otherwise everything else was unplugged . So I plugged everything back in and it booted up so I don't know do you think it could be my graphics card going out/ overheating or do you feel it could be another problem.


    Thanks,

    This sounds more like a power supply on it's way out.

    You didn't list what power supply you have.

    Hey,

    I have the OCZ Proexstream 1000W

    http://www.ocztechnology.com/ocz-proxstream-power-supply-eol.html

    So it's a nice PSU not a crappy one.

    But if it's the power supply then why would everything still have been getting power and just nothing showing up on the screen. I mean my graphics card runs between 61 and like 70 degrees Celsius so that's really hot. So I know it's overheated before. I ave even changed the thermal compound on the GPU cooler and it got better but still runs way to hot.

    You can adjust the fan speed in the nVidia Control Panel, you can try different drivers too; there were some older drivers that were known to cause certain cards to run hot. Or the card could just be on it ways out.

    Hey,

    Yeah I adjusted the fan speeds a long time ago and so there all the way up and it had helped a little but not a whole lot. Also I always update the drivers so I have the latest drivers. Anyways I have been thinking about replacing this card but I don't want to spend a lot like I want to spend under 100 bucks and maybe even under 75 but don't know what would be recommended. I would want it to be as good or maybe even a little bit better than the 8800GT that i have now. I really don't play games at least nothing major but do watch movies and videos on youtube and Netflix and it would need to be good for that and also be able to run my monitor which is an ASUS VH242H

    If you don't play games then any new card will do, all the rest can be handled by the cheapest modern card.

    Here's a Radeon HD 6670 1GB graphics card well under budget: http://www.newegg.com/Product/Product.aspx?Item=N82E16814102988
    It matches the Geforce 8800GT in gaming performance and excels pretty much everywhere else.

    also quick question is there a difference between the

    Sapphire 6670 card you suggested and then this card the Gigabyte 6670 there both 49.99 after rebate with 6.98 shipping

    http://www.newegg.com/Product/Product.aspx?Item=N82E16814125403

    The only thing I can see that's different is effective memory clock which is 1333 MHZ on the Sapphire and 1600 MHZ on the gigabyte so I mean is that a big deal or not.

    It's the same GPU just that the card is made by a different manufacturer and some manufacturer's use different RAM types and speeds, faster RAM may give it a slight performance boost but in general use it makes no real difference.

    Hey,

    OK thanks and also I was thinking that I could use the card in the future for a future build which I hope to do pretty soon I already have a Mobo and PSU and so the Mobo uses an APU so I would have/want the AMD A8 3870K APU processor which has the graphics card built into the CPU and in this case a 6550. I know that you can do like a Crossfire/duel graphics between the Graphics on the CPU and an added card, but I don't think you could do that with either of these cards. So do you think going with something like the XFX 6770 might be a better option just for the fact that I could transfer it to a new build.

    Hey, OK so even though the Sapphire Radeon 6670 says it can't do crossfire X it you're saying that it will be able to do that with the A8 3870K or did you mistype and meant to say a different card since first you say I can't do crossfireX with the APU but then you say the 6670 can even though newegg says it can't.

    Thanks again.
