Windows 7: Various bsods on x64 /i5 / 8g mem

Various bsods on x64 /i5 / 8g mem

I've built a new pc and having contant bsod problems with it

I've tried
  1. run memtest86+ (20h - 4 or 6 passes, no errors)
  2. use just a few modules of ram
  3. update video drivers (ati from winupdate -> ati official 8.801.0.0)
  4. increase default ram voltage set by mobo 1.25v to manufacturers recommended 1.65v - that reduced bsods significantly

There might be a problem with ram - system w/4modules is failing more than w/3 modules

Also I have a Vmware Vistax32 installation. After I've reintalled ati drivers, pc might bsod when i resize vista guest window.

Also i must tell that i have 8pin cpu mobo port - but my psu has just 4 and thought that it will suffice.
Oh, one more - w/4 modules I've issued constant winrar problems with unrar (damaged archive), w/prime95 - precision loss on one of cores during the test, and w/utorrent - torrent check may fail after the successful download.

Thanks a lot, I'll appreciate any help!

Sorry, but I'm still getting errors, now memory management. Now the PC hasn't rebooted automatically, it just halted w/bsod.
I was running with all ram placed.

Please uninstall Daemon Tools or whatever similar program you are using, as it is using SPTD. When done, remove SPTD with this tool:
a6de0e96.SYS                     Tue Jul 14 17:12:55 2009 (4A5CF4D7)
spye.sys                         Sun Oct 11 16:55:14 2009 (4AD24632)
Your Logitech QuickCam drivers may have something to do with it too:
Unknown_Module_fffff880`07aea000 Wed Oct 07 04:27:20 2009 (4ACC50E8)
That represents lvpopf64.sys. Update your Logitech software, or remove it completely.

Could you try a different PSU? Before I even read your part about the motherboard connector and your PSU, I had already made a note to ask you about the PSU, on account of the RAM situation.

You might return the PSU you bought, and purchase one of these instead: - CORSAIR CMPSU-550VX 550W ATX12V V2.2 SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply - CORSAIR CMPSU-650TX 650W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply

Finally, try testing RAM sticks individually, as outlined in Part 3 of this guide: RAM - Test with Memtest86+
