Dell Dimension 2400 w/ Windows 7- CANT CHANGE RESOLUTION???

Then download and run this file R106456

It runs, but then when it is all over, Windows tells you it is not compatible with this version of Windows.

Install via the Device Manager. See Windows Reinstallation Guide page 431-433:

Right click the device and select update driver. Select location as C:Dell\Drivers\R106456

No method of the R160456 install worked for me. I went to the "driver guide" site and found a "custom" version of the Intel-direct driver (driver download 1454943) and it works flawlessly now. Just remember to DECLINE and NOT "next" any/all offers during the install process. Resolutions up to the 1280 range are now available. Much better than the 800x600 that Windows7-internal driver peaks at with more than 256 colors. And the best part- it was FREE! I was half tempted to upgrade the video to a discreet card, but I found that driver instead. I thought at the time that windows 7 was an UPgrade, it seemed to have taken me way back (visually at least) to the 386DX CPU/256Meg video card days. Didn't like that recent-retro visual at all. All better now.

The Sparkle GT 210 PCI is a great Windows 7 video upgrade.

That PCI card being in the >$50 range, the FREE driver I found on Driver Guide is much better for me. That card also seems a bit of overkill for the Dimension 2400's other capabilities.

The free driver will neither enable the Aero interface nor offload video decoding, but if it works well enough then so be it.

Almost all of the PCI 2.2 cards are over priced.  For $99 you can get a newer system like a GX620 that is faster and uses DDR2 and has PCI-E video.

My GX620 needed several mods to be a good Win7 machine.

Yes but the GX620 can use 3.5 gigs of Ram,  Windows from XP to Vista/7/8 with NX bit in the CPU.

I have Seen them WITH WINDOWS 7 for $130.  Upgrading a 620 Tower is useful and Items like Power Supply or Video card can be carried forward if upgraded.  If you choose the Right Ram speed it to can be used forward in GX745, GX755 and GX760.

4GB kit (2GBx2)  
DDR2 PC2-6400 • CL=6 • Unbuffered • NON-ECC • DDR2-800 • 1.8V • 256Meg x 64 •   •  Part #: CT915221

I have seen Overpriced PCI cards at $50 or more.:emotion-3:

If the OP already has a non-Dell Windows 7 license, upgrading the motherboard and CPU is an option for some future point.

i had the same problem, i installed window 7 from windows xp, when i got your suggestion i followed the instraction,

woooow, the thing actually works, now i am enjoying. thanks very much for your help.

I did notice that with the stock on-board video on WIN7 on the E310 or 2400s you WILL give up Google Earth capabilities. The way around any incompatibilities is to go search for a Nvidia GeForce 6200PCI 256-512MB (or WIN Vista/7 capable equivalent) card on your favorite auction site and pick one up for anywhere (I got lucky on the low end for a NEW one,) for $12-$30, and you can find them from used to New-in-Box. Just be patient. Before the 6200 is installed, make sure BIOS is set to automatic for video init, and you'll then have dual monitor capability, Just a couple of heads ups. Windows will find drivers, but if I remember correctly, to take full advantage of the card, you will need to find the driver: "307.83-desktop-win7-winvista-32bit-english-whql" and run it. And also to be careful of which output connectors the card has, and which your monitor(s) have. Some cards don't have standard dual VGAs, and you'll need the DMI to VGA adapter, otherwise you'll need to buy one. AND, Google Earth works fine, and your Windows Experience Index will go up noticeably. I haven't tried any other brand or model. I've had good luck with these, no matter which interface, AGP or PCI (plain), or on a Dimension E310, or multiple 2400s. And, if you pay <$25, all the better to save your system.

Remember, this works wonderfully up and until you want to run Google Earth. Then Whooaaaaa Bessie, and a big thud, and you need to shoot the horse. The cheapest way out if you want to use Google Earth... Go find an nVidia 6200 chipset PCI (plain, NOT pci-e) card. EVGA brand is usually cheapest, I've found a new 256MB one in box on the 'bay for $8. Most I paid was $30 shipped for a new 256MB one there. I've got 512MB used cards there for $20 also, but bang4buck, 256MB cards are the way to go. Then, for that added expense, G/E runs flawlessly, you can run SETI/BOINC with the GPU version programs, AND, you even get a second monitor output! Yay! Just remember to plug your monitor into the new card of course, set video in BIOS to auto, and VGA aperture to highest, or, 256MB. BeenThereDoneThat, & cursed like a sailor- Duh, change the monitor plug over to the new card.... Then the only other things left to do to your 2400 are to increase the RAM to the full 2GB, and upgrade the CPU to a SL6PG or a SL6S5 3.06GHz HT CPU for $25ish (also on the 'bay). Maximum parameters required for the 2400 are: HT (HyperThreading- remember to enable in BIOS), 533FSB, and NO SPEEDSTEP. (I know, wrong forum! Shoot me.)
These CPU Numbers are the best bang for buck. Then you're done. Have fun.

I got DIM3000's, 2350s, all basically the same MBs, & all have the nVidia 6200s in them, all running 7ULT flawlessly with 2.2GHz-3.06GHz CPUs. The 6200 is the lowest number nVidia card and lifesaver to do WIN7 conversions well. The 6100 I had does Win7, but was on-board, so no opinion on the card version.
