JMark1 Posted September 12, 2008 Share Posted September 12, 2008 Hiya! First time poster here. Unfortunately I wish it was under better circumstances. I'm looking for some help. I've had this quad SLI system for about 2 years. Never overclocked it. Ran Windows MCE 2005 until this past April when I decided to upgrade to 4 x 1GBs of the Corsair Dominator 1066MHz RAM and Windows Vista Ultimate x64 in order to utilize all 4 gigs. Ran great until just recently. I upgraded to nVidia's latest WHQL certified driver in July, v175.19. Installed August's Microsoft critical updates. Not long after I began getting BSOD with memory dump when watching videos at YouTube.com. Would crash on random web pages if a flash applet was running. It always names nvlddmkm.sys as the cause. When Windows reboots, the self-diagnosis blames the nVidia graphics driver for the crash and that no solution is currently available. It then suggests manually updating the driver among other things. I attempted to research the problem online and discovered it's a fairly common problem with a multitude of various fixes. None of which is a documented sure thing.... Booted into safe mode, uninstalled driver, ran driver cleaner v3, installed previous version / beta version etc. Crashed no matter what version I tried. Next, I read that it could be that my new memory may not be configured properly. I went to Asus' website and updated my BIOS from v1701 to 2101 and went in and set my memory timings manually. 800MHz 5 5 5 15 2T 2.1v. The crashing stopped for approximately 3 days before starting again. Next, I read that the RAM wouldn't be stable unless I set them to 667MHz and overclocked the CPU or FSB clock. I've never done this before but am currently trying to research some articles to familiarize myself. Learned quite a bit but haven't attempted any settings yet. In the meantime, after all the uninstalling and reinstalling of several different nVidia graphics drivers, my Windows Live OneCare began acting buggy and I decided to uninstall and reinstall it. The uninstallation and reinstallation were both unsuccessful. I suspected my Windows Installer of being corrupted. Rather than trying to repair what looked like an increasingly corrupted OS I decided to just take the plunge and reformat and reinstall Vista. Back to fully updated SP1 clean install, showing 4 gigs RAM, installed latest nVidia beta driver 177.92. No more random crashes but haven't surfed to YouTube either. Aero and Dreamscene run without a hitch. Showing all 4 GPUs functioning. BUT...whenever I go into nVidia control panel and attempt to set quad-SLI, nvlddmkm.sys BSOD w/memory dump. It does this EVERY time. I always was able to set quad SLI when I ran WinXP MCE 2005. This rig ran good with quad SLI enabled in Vista and 4 gigs RAM from April to August. Is this a memory stability issue from untweaked settings, bad graphic driver or could I be experiencing a hardware fault? Bad PSU? Graphic card? RAM? Like I said, this problem is quickly becoming an epidemic online. Any help is desperately appreciated. Link to comment Share on other sites More sharing options...
