The issue Im having is that my monitor goes straight into sleep mode with VGA no input signal.

Ive tried uninstalling the ATI 4200 graphics card drivers and disabling it, through windows
Ive tried disabling the ATI 4200 through Safe Mode start up
Ive checked BIOS and PCI-E is on for Display (On Board is off)
Ive checked all my connectors and made sure that the card was slotted correct
I have both PCI-E connectors plugged into both of the 6 prong plugs on the new Radeon HD 6870
Ive tried to download the new drivers from AMD for the Radeon HD 6870 before switching the graphic cards around

The Radeon HD 6870 is getting power because the fan is coming on for it, but I still cant get the monitor to come on when computer powers up, shows VGA with no input signal.

Im really confussed on why this isnt working, I thought with the card plugged in and no drivers from the old card on my computer that Windows 7 would pick up the new card and then would ask for a driver update/install.

Anyone have any ideas on what I need to do to get this to work, its really driving me crazy

More about trying upgrade radeon 4200
  1. did you connect the monitor to the 6870 nad not hte internal after you put the card in
  2. Yes, I plugged it into the 6870 card port and not the old port. I do have to use an adaptor for the 6870 port though, it has 2 DVI ports and no VGA so I have to use the VGA to DVI adaptor that came with the card
  3. did you try both dvi ports with the adaptor
  4. No they are different types of DVI ports, on the right side of the ports one has the 2 prongs on top with a slash in the middle and 2 prongs below, the other port is just a slash on the right side...sorry not sure what the technical terms are for the ports style

    The adapter I have has the 2 progs on top and bottom with the slash between them
  5. look in card manual or box and use the dvi port not the mini one this link show the connector and there name
  6. first install HD6850 drivers then pick your 6850 in the drivers in available
  7. I bought a 600w, its in my original post...bought a Corsair CX600
  8. @Kishere he bought a CORSAIR Builder Series CX600 V2 600W ATX12V v2.3 80 PLUS Certified Active PFC Power Supply
  9. the cord I have for the monitor is for a VGA port, the card came with an adaptor but it can only plug into 1 port..from the site you linked it would be the one with the Analog ports ( the diagram showes a + sign with a plug in all 4 corners of the +)...the adaptor wont fit into the other port on the card
  10. @ Scout_03 sorry for the bad discription of the port used on the 6870 is the DVI-I (Dual Link) the the adaptor fits in...the other port is the DVI-D (Dual Link) and the adaptor wont fit in to that
  11. we all make mistake we are human just i idea could your monitor will not be able to support the 6870
  12. Im just tired and frustrated that this wont figured it would be easy..I havent upgraded a graphics card in a long time but the last time I done it on a old computer it was easy, just uninstal drivers of old card, plug in new card, turn on computer and windows asked for the driver for the new card, pop in cd that came with card and that was that...this one I just can figure out
  13. Not sure on the monitor, it is an HP w22 LCD Monitor but not sure on how to find if it will support the 6870
  14. do you have another monitor or tv tha you could plug the mobo to it been lookin at your monitor and he got a dvi connector on it use the cable with the white end to mobo and monitor the blue one is vga
  15. In all honesty I believe that Im either missing something on setting up the new card, either not getting the old card disabled properly or the new card I have is a bad card
  16. No I only have this monitor
  17. also on button mark source select dvi send you the link for hte monitor it set isefl by default to vga check page 17 to test monitor
  18. Are you saying when I connect my monitor to the DVI-I port on the graphics card, hit the source button on the bottom of my monitor and it might switch me from VGA to the DVI? Right now I have the old Card and PSU in the computer (thats how Im getting on to the forums) and I hit the source button at the bottom of my monitor but no menu came up, it just showed No Signal and then came back to regular screen

    I only have the on VGA connector cable and a VGA to DVI-I adaptor

    Or do I need to buy a different monitor connection cable that has a DVI-I male end on it?
  19. the forums are not updating fast enough for me to keep up with some of your replys, so please dont get to frustrated with me if my reposts seem out of order. Your the first person that has replyed to me and I dont want to lose
  20. still here for another 15 minutes strange that you could not see the source settings did you installl the cd that came with the monitor
  21. Ok, what I think your are telling me is that I need to plug a DVI cord into my monitor and use it to connect to the DVI ports on my Radeon 6870, once I do this I may need to hit the Source button on the bottom of my monitor to switch it from VGA to DVI?
  22. The monitor that I have is from an old computer, I dont have a CD for it.
    I been useing this monitor with the new computer I have for about 9 months now and never had to use a CD to use it.

    Do you think that I might need to get a new monitor to use with the new video card?
  23. Ok, I just seen the yes response to the getting a DVI cord..I will do this tomorrow and post back if it worked for me.

    Thank you for all your help so far, I really appericate it.

    Sorry if my replys might of seemed a little off, the refresh for the website seems a bit slow for me
  24. be in tomorrow
  25. Also, maybe what you wanna do is make sure the video card is connected to only "one power cable" for the PCI-E cable. I have two PCI-E cables, on these cables are 2 6 port connectors. I just recently bought a Nvidia 560ti 448 cores, and for some reason, it just wasn't working, till this day I'm not sure if connecting it to only 1 PCI-E cable worked... or what? Cause everytime when I turned my PC on it said it wasn't find the card, but for some reason the card's fan was working just fine. I would try to install the card's drivers and it wouldnt wanna find the card. The installer kept saying it could not find any nvidia cards. During this period I kept installing the drivers from the nvidia site. So, my other options were to disconnect the "2 PCI-E cables" I had connected to the video card, and only use 1 of the cables (remember, one cable alone had 2 6 port connectors, the only reason why I didnt connect just 1 cable was because its a REALLY tight squeeze just to connect both of the 6 port connectors. Mainly because I have to because bend the small cable to fit the 2nd one into the slot.)

    After I did that, I turned on my PC then finally try installing the drivers from the CD and not downloading them, eventually the installer found the video card and it worked fine!

    This might help ya, im not sure... check it though.
  26. check hp for the exact name or the monitor one model support up to vista but the other have driver to win 7
