The Infinite Loop
It has various errors on Windows XP and a fewer on Windows 2000 with Nvidia driver NV4.dll.
* It causes computers to reboot.
* IRQ, Code 10; device won't start (device manager). (changing IRQ's by switching cards won't help)
* EventType: 0xEA - Thread Stuck in Device Driver Microsoft Q293078
* Graphic card trouble. The GeForce 1/2/3 and sortlike cards.
* Display trouble.
* OpenGL; spontaneous reboot, hardware lockup or insufficient virtual memory error from WinXP
* Direct 3D, Hardware lockup, BSOD with a message about an infinite loop error with a Nvidia driver
* BSOD error message - this varies but refers to a problem with "nv4_disp.dll"
* Error messages;

* Blue screen with the message that the infinite loop is caused by NV4 DLL.
"The driver nv4_disp for the display device \Device\Video0 got stuck in an infinite loop. This
usually indicates a problem with the device itself or with the device driver programming
the hardware incorrectly. Please check with your hardware device vendor for any driver
updates."
* Causes instability on different systems.
nv4_disp.dll, the Nvidia display driver, is causing this in combination with Windows XP/2000, grapics cards and motherboard chipsets like Via and Intel and many others.
"It appears that this is all due to a BIOS setting which basically has to do with the way that the CPU and RAM communicate with XP and DirectX 8.1. Basically, PC components compete for system resources and the Video drivers give too much ram to the video card which is the root cause of this problem. Specific drivers have agrivated the problem for some (Such as NVidia's 23.11 Dets)". (DDR Zone)
"So what does it do?
It closes the RX55 memory register in BIOS. The RX55 register's official name and function is Memory Write Queue (MWQ) timer. The MWQ timer is actually a timing device included in the memory host controller to prevent write data being held in the memory queue too long. After the data has been in the queue too long it times out. This timed out data is then given a higher write request priority. Now that might sound nice – a bit of extra performance BUT the procedure fails when overloaded. 3D games and Win XP put too much load on the memory queuing timer procedure. The nVidia new driver exaggerates the problem even more as the driver enables nVidia cards to use even more memory than previous driver versions."

"What is this XP: Infinite Loop problem that some users are referring to. I don't have... and don't want it!!! LOL."
"The Asus 14.62 drivers STILL cause the infinite loop problems in XP with my Asus V6800 deluxe.. Damn I wish a fix was out.."
"I have been having dificulty getting my new VisionTek Geforce3 to work with WinXP. I get a blue screen with the nv4_disp file error about an "infinite loop". VisionTek tech support says a possible solution is changing the AGP drive strength and that I should contact my motherboard manufacturer."
"This is a widespread problem affecting Win XP on various motherboards, but seemingly more common with NVidia graphics card (probably because they are a common card on high end systems) that does not have one single solution. Search these newgroups for "NVidia" and/or "BSOD" or "infinite loop". See if any of the workarounds apply to your system configuration."
"I am going back to Windows 98 SE and wait until they solved this problem"
Hope and pray that Microsoft, Nvidia, Chipsetmakers come out with a good solution !!! (SOON).
E-mail Nvidia, Microsoft, chipsetmakers en let them (detailled) know of the problems your in !!!
There are some solutions for this problem for some systems....not all.
* Always try the latest videocard drivers, GeForce users should try the latest Nvidia drivers
* A faulty videocard could produce the same errors as metioned at the top of the page, to be sure try another videocard and try if your videocard will work on a other system with same operating system (XP).
* Via based motherboard users take a look here: Viaarena
* For some VIA "users" the "4in1 Drivers" did help
* NVmax 4.00.47 Tweak program that says to the Infinite Loop Fix for all Operating Systems running Det. 23.00 or higher. download also here: VooDoo Files Charnleys
* Some people are helped by 21.83 Drivers Nvidia
* For some people these links helped:

* Some BIOS setting that helped some people (at own risk):
Video Bios Shadow - disable
Video Bios Cacheable - disable
System Bios Cacheable - disable
C8000 – xxxxx Shadow - disable these values
Assign IRQ To VGA - This MUST be enabled
VGA Palette Snoop - This MUST be disabled
Enable ESCD - disable
Power Management - disable
DPMS - disable
Virus Checking - disable
PnP Aware OS - disable
Turbo External Clock - disable
Cache Read + CPU with pipeline - disable
AGP Aperture Set to 256MB
ACPI - disable
Readers Tips:
* Last weeks I got frequently this kind of failure. By coincidence I made once a safe mode start and saw a warning for a damaged or missed ntoskrnl.exe.
It was still present but I refreshed it from the CDrom.
Since then no more nv4_disp.dll problems. My system : Windows XP Home SP1.
* Also some may have more luck with version WDM 1.08 find it here and other good drivers. http://neverwinternights.dk/downloads/drivers
* Just so you know, I was getting the loop problem you are describing....I ended up reaching into my PC to yank the Nvidia card and met a nasty surprise:
It was hotter then hell!!!!
Nothing else in my case was hot....the card blew out its capacitors.

I think the above article might be describing what is happening to many cards...as 5 of the cards I've now seen do this all have the brown electrolyte leaking from the caps.
* I solved the problem by disabling FW and SBA since I found my motherboard doesn't support them altough my card does...
