Since I built it i have had nothing but problems, first off vista did not like 8gb of ram so I had to reduce it to 2gb just so I could install without it crashing then once installed I had to patch it to be able to use the full 8gb of ram. Once in windows the pc BSOD frequently with random errors from IRQL equal to Memory management errors.
After a few days of playing and increasing some of the voltages to components and installing a few patches i have got to a stage where it is a bit more stable and it just might allow me to run a game for an hour before finally crashing.
but now to the nuts and bolts of what this post is about
I recently bought 2 games, Crysis and Sims city societies. Installed them and patched them. I have all the latest drivers for my hardware. When I run the games and I have tried all the graphics settings from low to ultra. They all work but I am getting a Vortex / texture issue where graphics polygons are arching across the screen from an object into infinity. Its not the whole game and its playable for a few minutes until it finally crashes. Has anyone had these problems, could it be a graphics card hardware issue or maybe just that vista ultimate 64 is bad with games.
Sounds like you had some memory issues? It may not be increasing the voltage as much as a bad stick of RAM/ DIMM on the mobo. Id start by testing everything with Memtest. Test one DIMM at a time with each stick.
I have a Q6600, vista 64 ultimate and just finished Crysis on High settings. It only crashed twice I believe but that was when I was using beta video card drivers so no concern. I think all I changed for settings in the game was everything to High.
I'd then do some stress testing with Prime 95 for the CPU followed by running some in game benchmarks for the video card. Also, be sure to be watching your temps.
A good free tool that has a whole buncha stuff is System Information for Windows:
Good luck and be sure to report back with anything you find!
Ive seen a similar problem in other OS's also. You could try to pull your video card and ram out then re-seat them. I've seen that happen with a Graphics card and just re-seating it fixed all the problems.
I'm not saying this is the 100% answer, but this has been the issue before.
Also the Video card could possible be defective. Have you ran your build on anything else besides Vista64 ?
Or have you tried running your build on just 2G of memory. Just changing the sticks out one by one or two by two and see if you have a bad stick.
I did stress testing for a good few hours with no errors, i also have run memtest for ages with no errors reported. i have had the motherboard changed and have tryed it with 2gb 4gb , 6gb and 8gb in differant dimms etc and no change .
