Re: no video input
Is your CPU fan spinning?
If so, check the coolant (silicon gel (aka Nano/Thermal grease)) between the CPU and the fan (if there isn't much there, or it has dried up, you'll need to replace it).
Additionally, check the new PSU is the same voltage as the previous one (e.g. 230, 400 etc), and if applicable, that BOTH power cables are plugged into the board (some boards require both the large one, and a smaller 4 pin cable be plugged in).
If you've checked these, and the fan is spinning, it's possibly a problem with the board (as could be the case if you've checked the above and the CPU fan is NOT spinning). The reason I say this is that when PSU's go, they sometimes tend to take the board with them (especially as in this case, with the drives and video card not receiving power either).

I like the jumper and cmos and enable/disable portions
on 11 Oct 2009 8:00 AM
Just fitted a new PCI graphics card (Radeon 9200) in my 4 year old Dimension 2400. The only way I can get it to work is to have both it and the on-board graphics chip running together - done this by selecting the Radeon as the default display and by not having the Windows desktop run over onto the Intel display. Problem: If I disable the on-board graphics chip as per the fitting instructions and then set my Bios to auto select, the computer boots and is active but all I get is a blank screen regardless of which output the monitor is connected to. Also, as I have the Radeon as the default display in Windows I don't see anything (no Dell boot screen, etc) when I switch my machine on until Windows log on screen as I have to have the Bios set to 'On-board' in the graphics option otherwise the aforementioned problem persists. Has anyone else encountered this problem, and if yes, has anyone managed to overcome it i.e. successfully disabled the on-board chip? Unfortunately there is no Bios upgrade from Dell that allows a user to select either auto, on-board AND PCI - the last one being ideal it would seem!
Posted byrdunnillon11 Oct 2009 4:58 PMI just configured a 2350 with a PCI card (Sparkle 8400GS), and I left the BIOS setting at auto-select. (I could find no way to disable the onboard graphics.)
I found that if Windows installed a driver for the onboard graphics before the PCI video, the onboard graphics were used for the default monitor. Thus, I got no image from the PCI video. I connected a second cable to a spare DSUB port on the monitor to the onboard graphics and switched inputs until I got video. Then I downloaded the appropriate video driver for the onboard graphics, installed, and rebooted. Upon reboot, I switched the default monitor from the onboard graphics to the PCI video, after which I could remove the second video cable.
Hope that helps!
Posted byJackShackon11 Oct 2009 6:32 PMSome additional information that may be helpful:
1. The Dimension 2400 uses an on-board AGP graphics chip that cannot be disabled in hardware. It shares the interrupt for the first PCI slot which can give you trouble if you decide to place your add-on PCI graphics card in slot 1. My own add-on card wound up in slot 3, so it might be helpful to switch to another slot before giving up.
2. If you do have your card in slot 1, try resetting the NVRAM (CMOS) by removing the battery for about five minutes. You can find instructions for that here: Dimension 2400 Service Manual. Look in the section on Removing and Installing Parts, Battery. While the battery is out and everything still unplugged, push the power button and hold it in for about fifteen seconds to ensure the discharge of any storage elements. When you put the battery back in its holder and fire everything up again, the computer will take a new inventory of its devices and will sometimes finally find the PCI video card.
3. This next you've probably seen, but it bears repeating: Before attempting to install the new card, go to the Device Manager, Display Devices, and find the Intel Graphics Adapter. Double click it to bring up its properties, go to the bottom of the little window to Device Usage, and click the small arrow on the right to get the menu. Select "Do Not Use This Device - Disable". This will disable the onboard driver and cause the computer to load the standard VGA driver that works with all the video cards. Sometimes the reason you see nothing on the add-on card is that Windows is still trying to use the driver for its previous video adapter which is incompatible with the new card.

Posted byrdunnillon11 Oct 2009 7:40 PMIt might help to disable the onboard video in Vista, as ATI drivers can clash with it and cause BSODs. Under XP it'll co-exist.
There is a jumper on the mainboard for clearing the CMOS. It is marked as such, and the manual will point it out.
The default Windows driver for the add-on card will work, but without acceleration and with a very low resolution. Also, if Windows installs the driver for the onboard graphics first, it will mark the onboard graphics as the primary display.
Posted byJackShackon11 Oct 2009 9:10 PMYes, I neglected to mention that if you get the card to work in the VGA mode you should be able to install the specific driver for the card. In the past I have recommended that no attempt be made to load the driver for the card until a VGA screen can be displayed.
Granted there is usually no conflict if the onboard driver is left in place; the problem arises when the BIOS sort of recognizes the new card but for some reason Windows fails to find a driver for it. In this situation you get video from neither the onboard port or the PCI video card port. This seems to happen a lot if the card is installed into slot 1. In the past I've corresponded with folks who seem to be able to get the card to work only by using the Windows multi-monitor capability; extending the screen onto the video card. The only irritation with this is that you get no video until Windows loads, so if you want to see the system setup screen you need to switch ports.
Naturally I realize that a jumper is there and is supposed to work, but removing the back-up cell makes certain that the NVRAM will be cleared.

Posted byrdunnillon11 Oct 2009 10:40 PMThe jumper definitely works, as I used it last week several times in dealing with a recalcitrant 2350.
Windows should find a driver for any VGA-compatible card; it'll be a default VGA driver. However, if Windows can find the driver for the onboard video, it will use that as the primary video, regardless if they are connected or not, and the user will get no video from the PCI card. I had this problem with the 2350, and had to temporarily install a VGA cable to connect the onboard video; after installing the drivers for the PCI card, I'd switch the primary monitor to it and all would be fine.
When I installed Vista on the 2350, I experienced BSODs on startup until I disabled the onboard video. I am not sure if this happens with nVidia cards as well as ATI ones.
I tried two cards with the 2350: an expensive HIS 4350 ATI and a much cheaper Sparkle 8400GS. The 4350 worked, but did not accelerate video playback (ATI said they did not support it over the PCI bus), so I RMA'ed it. The 8400GS installed without incident and worked perfectly and accelerates both standard and high-def video. Both cards were installed in slot 3.
Do you get any display at all? If so then it's needing a driver. If it isn't working at all then:
1. it's in the wrong slot - slot won't support it. Double check the board specs. Some versions say it's supported but it really doesn't.
2. (without my looking at the mother board manual...) is there an onboard video card? If so there could be conflicts. You'd have to disable the onboard video and try it.
3. the radeon is bad.
If the board supports it etc you should be getting some kind of display even if the resolution is low. (then you'd need to adjust it). However if you aren't getting any output then it is one of the things listed above.
Remove the Power connection. Open the CPU Cabinet, Locate The RAM, remove the RAM by Sliding both Clips, Insert it Back to same Slot or another. Try to boot it again, if still same problem then, Change the Graphics Card with New one. If still have the problem then only Replace the Motherboard. Best of luck
The option to disable the onboard graphics is in the BIOS.
You need a PCI-express card. You should not be trying to fit any graphics cards into the PCI slot.
The VGA/HDTV conection should have been supplied on a seperate card.
Your support page is here http://www.asrock.com/mb/overview.asp?model=775twins-hdtv
note that even if the motherboard supports both onboard+PCI-E,
G31(GMA3100) graphics wouldn't help much at all, trust me. You'll want
to buy a new PCI-E card if
you plan on doing any gaming. Not knowing what game(s) you plan to
play, your budget, and what processor you have makes it tough to
suggest an exact video card. So, check out this site to select the
best card for your budget and game play:
Enter your bios & make sure the video is set to AGP.
Your card has two VGA outputs. One VGA & one HDMI (high def). Switch your monitor cable that connects to the video output to the other femal connector at the Pc. You can do that while the system is running.
If that does not help think of this. You have been using the onboard video for some time. It must be dirty as heck. Remove the 6200 & blow it out with some canned air. No canned air. Use a clean paint brush & a sweaper. Than grab some alcohol & a cotton swab. Lightly dampen the cotton swab (no dripping). Wipe the copper retainer contacts of the video slot. Let it dry completely. Re-seat the card applying even pressure side to side till the card is seated firmly into the slot. Some cards require additional power. Check your 6200's install manual.
