Display issue - presumed? - Win2K issue

Win 2K SP3
A7N8X2.0 Deluxe
AMD Barton 2500 + OC at 10.5x200(Previously known stable)
512 MB PC3200 LLPT XMS Corsair DDR
Geforce 4 Ti 4200 (latest 43.xx drivers)

I was moving my system from an old case to a new one. There was an issue with a loose wire from the power supply touching the frame of the case at one point which may have a bearing on this, but I doubt it since it did not touch any of the components directly as far as I know, and was nowhere near the affected component.(Touched the HDD bay)
Anyway, when this happened the power shut off. I fixed the wiring and rebooted, there was an issue with the HDDs and CDROMs not being recognized. This turned out to be due to my having wired them incorrectly so the cable settings and jumper settings were conflicting. Again, not sure this is relevant but am making sure to mention it
When I booted up for the first time after the wire had touched the case, the OS appeared to load fine(Boot loader appeared, first Windows 2000 splash screen appeared and disappeared)
For anybody who has used Win2K, you know that there is that fullscreen splash screen with the loading progress bar, then shortly after a blue screen with a smaller window that simply says Windows is starting up. Well, when the screen flashed as if to go from the former to the latter, the screen came up that appears when you schedule, for example, a CHKDISK session on a disk that is currently in use.
This screen(Though it lasted too little time for me to read it comprehensively) said that the disks needed to be checked for errors and so on(though this seldom appears even when a power failure happens in Win2K) and began to check the disks. About two seconds later the screen exploded. Not literally, but it did the coloured squares thing -- anybody who has ever jiggled an old 2D game cartridge while the game is on will know what I am talking about -- all over the screen. Well, I reset the system. This time it did the same thing immediately after the first splash screen disappeared(The bar filled completely, just looked as if it was going to proceed as normal). It seemed to happen right when the OS would change to the resolution it was set to as desktop default.
Anyway, I can get the system to boot into safe mode, or safe mode with networking enabled. Last known configuration did not work, have not tried VGA mode(had to leave for work)
I have run a scan disk session on all partitions and all appeared to have NO errors, though it was odd that the system rebooted spontaneously right when it finished scanning the C: drive. However when it rebooted it continued the scandisk as if nothing had happened, and it said that C: was error free.
I am a relatively computer wise person, but this has me tearing out my hair. I have tried power cycling, grounding out various components(while off), reinstalling my display drivers, etc. Nothing seems to work, and I REALLY want to avoid having to reinstall the OS.
BTW: cannot use the repair function of the Win2K CDROM, will not recognize the Win2K installation even though it obviously is valid since I can boot into safe mode.

Anyway, sorry for the massive topic, but can anybody please help me? PLEASE???

Having custom wired my fan setup in my system, i've had wires touch my case and off goes the power! This doesn't hurt the system, as the PSU knows there was a short, and shuts itself off to avoid damage. Not to insult your intelligence, but is the video card is tight? If you think it is, try taking it out and putting it back in. Also, did the new case come with a new power supply? If so, try hooking your old one up instead. That's really the only thing that changed.

I could always take it out and tighten it again, just to make sure.
I'm using a relatively standard CRT monitor -- I noticed it only has 14 pins when the jack in the video card has 15, is that normal?
Am going to reset and tighten connections while system is powered off. Status update soon.

Edit: see next topic, posted solution invalid.


Well, I'm a fool. I was trying to be "neat" and ended up putting too much power-hungry equipment on one cable string, so when I reseated the video card, I felt that it was much hotter than it should have been. Evidentally the extra processor strain from going from 640x480x256c@60Hz to 1024x768x32bit@80Hz was heating it up so much it destabilized. When I moved the GPU cooling unit to another power string and tried booting normally, voila! it worked. Thanks for giving me the tip -- and enjoy your new rating.

Or maybe not. The problem happened again almost immediately after I typed that last message.
Apparently there is still something causing this, but it doesn't appear to be heat-related; I was touching the GPU heatsink this last time and it was barely warm to the touch. But it does appear to be something with the video card.
As for the power supply, I am using the same power supply as before, a Thermaltake PurePower 420 watt affair.
The total devices present on my system are:
3 80 mm fans
1 AMD Barton 2500+ at 1.65 volts
1 512 meg of PC3200 LLPT XMS Corsair DDRRAM
Geforce 4 Ti 4200 128 MB
Turtle Beach Santa Cruz
IBM Deskstar 40 GB
WD SE 80 GB HDD
AOpen CDRW
DVDROM
Generic Floppy drive
That is ALL of the components that are taking power in any way, shape, or form.
I can't imagine all of this adding up to > 420 watts, could I be mistaken?

Hmm, something else I just noticed: the AGP warning light on the mobo is flashing intermittently. I have seen it flash twice so far. What could this mean?

If you have another video card you could try, that would be a fairly easy troubleshooting step. If you happen to have a decent voltmeter, also try checking the power supply's voltages at various points and see if the 3.3V, 5V and 12V are within the realm of reason (10% for 12V and 5% for the others). Or try another known-good power supply (cut back on your devices if necessary). Good luck! :)

Unfortunately I do not have another video card. I have tried wiring things all sorts of different ways to make sure nothing was hogging all the juice, tried dicking around with all sorts of BIOS settings, etc, etc...
I have a voltometer, but not sure entirely where to test nor what to look for.
Would using this device while the machine was running pose any risk in terms of machine damage?
Also -- I've noticed it happens right when the card tries to switch to desktop resolution, so seems to be a problem with either higher resolution, colour depth, or refresh rate.
Which is most stressful on the card?
Finally, I still want to know -- is it normal for the connector from the monitor to the vid card to only have 14 pins?

14 pins is common. I don't know why there isn't a 15th.

Using the voltmeter on the main ATX cable or the drive plugs is safe to do while the system is operating. I wouldn't go and get fresh with the memory modules if you're not sure what you're targeting, but yeah, the power supply harness is a safe target. What I'd be watching for is major fluctuations during boot-up, or significantly out-of-spec levels overall.

Roger that.
More info: I can boot into normal mode just fine if I uninstall my graphics drivers.
I am going to remove all traces of the driver files from the system and reinstall.
Last time I did a dirty reinstall, so maybe it just needs to be purged.

No go. I uninstalled all display drivers, can reboot into normal mode
Installed the 43.45 drivers, which are what I've been using since they came out, and the same problem happened.
I'm going to test some voltages on the power supply and examine the video card for visible damage.
In the meantime, what else do you guys think it could be?
Edit: damn, no battery for the voltometer. Cleaned the video card thoroughly and the AGP slot and such. Am going to try reinstalling drivers again.
