Re: [H] Video Problems (NVidia related)
Sounds like a bad vid card to me. -Original Message- From: Bill Cohane [EMAIL PROTECTED] Date: Fri, 26 Jan 2007 04:52:02 To:The Hardware List hardware@hardwaregroup.com Subject: Re: [H] Video Problems (NVidia related) At 00:57 01/26/07, KHumrich wrote: How is your Power Supply?

I have to admit that I didn't consider the power supply. On the one hand, it's a PCPC 510 Watt supply (costs over $190) and I would hope that it isn't the problem. On the other hand, there are seven Seagate 15K Cheetahs in the case (and SCSI CDRW and DVD reader) along with the dual processors. Actually, the computer would show video just fine in 640X480, if (and only if) it was using the Microsoft generic VGA driver. (That's what choosing VGA Mode in the boot menu results in.) But the video always failed at 640X480 after booting into regular Win2k. (Video would corrupt a fraction of a second after Win2k started to display the desktop in regular Win2k.) I think video was failing right when Win2k switched to the manufacturer's video driver (either NVidia reference drivers or Asus drivers). So at the same resolutions, the MS generic VGA driver always worked but the NVidia (or Asus) drivers wouldn't. Okay. An hour ago I changed video cards again. I replaced the Asus FX5200 with a Leadtek A6200 that came by UPS today. First I uninstalled the NVidia driver software set, then deleted the video card from Device Manager, and then ran an utility called Driver Cleaner. (Thanks M!) Then I pulled the Asus card and put in the Leadtek card. I installed drivers from the Leadtek CD-Rom and all seems fixed. I've warm -and- cold booted many times and it is now running in 1600X1200 with 32 bit color. Time will tell if it keeps running. I don't know if the problem was a bad video card, corrupted drivers (fixed by using Drive Cleaner), or if it will return.

Re: [H] Video Problems (NVidia related)
You mean you don't CARE? I would be going crazy not knowing! I would want to do the SAME cleaning and put the old card back in this time, And see if it works, and if it doesn't work, then the card was the problem.. If it DOES work, then the problem was the drivers, which you cleaned up. You could always do it, just so we know what it was... ) Ken ---Original Message--- From: Bill Cohane Date: 1/26/2007 1:58:18 AM To: The Hardware List Subject: Re: [H] Video Problems (NVidia related) At 00:57 01/26/07, KHumrich wrote: How is your Power Supply?

[H] Video Problems (NVidia related)
Hi Guys! I've been trying to set up one of a new Dell 2007FP monitor the past two days and I keep having big problems. I'll understand if you don't want to read all the following, but doing so will let you know all the steps that I've tried. Basically, my system boots okay into Win2k VGA Mode (640X480, 256 colors, 60 Hz.) but not into regular Win2k. (VGA mode is like Safe Mode in the boot menu, but it has more functionality.) The system is dual PIII-1400, 1GB RAM, running Win2K SP4 and I'm using an Asus GeForce FX5200 128 MB video card. (I had been using an older Asus FeForce FX400 with no DVI out before changing to the flat panel monitor.) I don't run games, and the motherboard is AGP 2X only. I installed the 2007FP monitor and FX5200 video card with a DVI cable and installed the Asus drivers that came in the box with the video card. After successfully rebooting, when I attempted changing to 1600X1200 (32 bit color, 60 Hz of course), the monitor screen became horribly corrupted (only streaks of color side to side across the screen, from top to bottom) and dropped to power saving mode after about 3 seconds. I could now only boot into VGA Mode. I tried changing drivers to the NVidia reference drivers that came on the CD-Rom, then the FX5200 enhanced drivers from Asus's website, and finally some NVidia drivers that I had downloaded sometime last year. I tried changing drivers the Windows way (update drivers from Device Manager) and when that didn't help, by running the setup utility on the Asuss CD-Rom. I always looked for and deleted all video software from Control Panel's Add/Remove Software and deleted all graphics cards from the system (including ghost devices after clicking show all devices) using Control Panel's Add/Remove Hardware. I'm using the 2007FP driver from the Dell CD-Rom. (This works fine on my other computer which has a Dell 2007FP monitor and Asus FX5700 128 MB video card.) Over and over I deleted all the utilities that NVidia or Asus set to run at Startup (NVidia Contol Panel and Taskbar utilities, and something called NWiz.exe). Tuesday night I finally got the system to work at 1600X1200 (using the Asus enhanced drivers) in regular mode and ran the system for an hour, rebooting several times. Then I powered down for the night. Wednesday night I powered up but video had become corrupted again. It would work only in VGA mode. Then I changed from DVI cable to VGA analog cable and installed NVidia drivers from their website. I finally had success and the system booted okay and let me change to 1600X1200. The system ran okay for about two hours, during which time I rebooted several times with no problems. But the one time I powered down (after Shutdown), the system wouldn't boot into normal mode when I powered up. Video was corrupted again, even though the drivers hadn't been changed and had been working only minutes ago. Would you say I have something corrupted (drivers?) that isn't being replaced when I change drivers? Or could it be a hardware problem (video card or monitor)? Remember that it always works using the Microsoft VGA driver (640X480, limited colors) but not with the Asus or Nvidia driver (even at the same 640X480). When I get it working, it continues to work after warm reboots but not after cold reboots. I've wasted 8 hours on this problem. I don't want to start switching video cards and monitors until I'm convinced that it isn't a driver problem. (I don't want to risk corrupting my main computer.) On the other hand, the problem may in some way be hardware related since doing a cold reboot is when the problem resurfaces. Anyone know of a driver cleaner program that works with NVidia and Win2k drivers? Google only seems to refer to Win98/ME utilities or links that are dead. Regards, Bill
