I've just installed a new MSI Neo 875p Mobo, 512Mb DDR ram (across two 256Mb channels) and a P4 3GHz chip.
But now my existing graphics card, a Geforce 4 TI4600 is giving me a problem.
After a period of time - up to 50 minutes from a cold start (ie the machine having been left off for 20 minutes or so) the system shuts down and restarts - but never gets beyond the 'loading Windows XP' screen before it shuts down and restarts again. I have to switch off the system, leave it for a minimum of 20 minutes, then start again.
I've had several error logs generated all of which say the same thing: ' The driver for the display device 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 display device vendor for any driver updates.'
I had the latest drivers installed (126.96.36.19904) but after this problem occurred a couple of times, I uninstalled the card and went right back to the native Windows XP driver. Unfortunately, a key file - nv4_disp.dll - wasn't detected during reinstallation, so I had to resort to the one existing in my system, which might not have helped.
The new Mobo has an AGP 8X slot, and my card is 4x - could this be part of the problem?
I wasn't sure if it would help, but I tried reducing the size of the AGP memory aperture in BIOS from 64Mb to 32, but I still had the problem. Should I try increasing it to the maximum memory of my card (128Mb?)
What else can anyone suggest I could try to get stability back?
