Hi, I recently purchased a Leadtek WinFast GeForce 2 Pro 64 mb ram for my P3 500 with 512 mb ram (AGP 2x is supported). I'm pleased with the speed of the card but lately I have been experiencing memory leaks. It may or may not be related to an event that happened about a week before I got the new card....I shall outline briefly what happened:
First, I doubled my ram to 512 so I could increase my AGP aperture from 64 to 256 (there was no option for 128). About a week after that, I had a complete structural collapse for no apparent reason (3 system files lost or corrupted, including HIMEM.SYS, WIN.COM not found, and my windows folder mysteriously moving from my C drive to my second hard drive...BIOS setup not responding). After many a trial and error with Dell tech support, I unplugged my second hard drive, and everything was back to normal (replugging the second hd worked fine).
Next, I can't remember if this happened before or after I installed the new video card, but my computer no longer shuts down by itself; it sits endlessly at the black DOS screen with a blinking cursor. Next, 99% of the time when I try to restard the computer, I get a Blue Screen of Death saying that there was an error in VXD VCACHE, and I need to hit the reboot button to get past it.
Back to my present problem... More and more often I'm getting a warning message that "System memory is very low. Norton AntiVirus may be unable to continue running properly." (I keep all my virus definition files up to date, by the way.) This happens most often when alt-tabbing in and out of Diablo II. Also, with each Alt-Tab, I notice that my free resources in My Computer Properties drops by a large amount. Also, I get a complete lock-up after playing through a few missions of MechWarrior IV (it happened much more frequently if I had it set to Ultra-High detail with Anti-Aliasing on). Neither one of these problems occured when I was using my old TNT card.
I have the latest LeadTek drivers, but I just noticed that nVidia's Detonator 3 drivers v 12.41 came out last month....would using the Det3 drivers solve this or is there another solution?
First off, I'm not familiar with either your specific video card or the drivers you mention so my advice is only how I would approach your situation and not a definite solution. From your description, it seems there are a few too many things happening to immediately know what to blame. So, I would suggest reverting to the old video card and seeing if your startup/shutdown problems and resource issues are elimintated. That will give you a quick sanity check on your system. If the problems do go away, put the new video card back in and start trying the nVidia reference drivers. Many people have reported lots of success with them compared to the drivers that come with their cards. Also, I've had several friends whose machines were notoriously unstable and in each case removing Norton AntiVirus solved the problem. I'm not saying it's a bad virus checker but in my experience it does seem to have more issues coexisiting with other software than other popular virus checkers. At the very least, try disabling the software and comparing performance.
As Atlantix said, it can be a lot of things related with software, namely the GeForce drivers - and most likely you now have a very corrupted windows. But on the hardware side it could be a power issue.
Anyway, try nVidia reference drivers.
