Win 7 HPrem, 6MB RAM, Asus P6T Deluxe Mobo, Nvidia 285GTX, Asus DX2 soundcard, 2 optical drives, USB Floppy drive/reader, 1000W Thermaltake Toughpower PS. I use MBAM, AVAST, and Super-AntiSpyware regularly.
PC began random freezes during POST. The first lockup I got gave me two minidump files that I read with WhoCrashed, telling me the cause was my Nvidia driver that happened to be the latest WHQL certified driver 301.42. I replaced the driver with an older WHQL certified(the number escapes me at the moment). I just doubt that conclusion. I had been using the Nvidia 301.42 since it came out in April. Anyhow I changed the driver. No joy.....
The next bootup problem occurred when the PC froze at the black Windows flag screen, the PC rebooted itself and asked if I wanted to do a startup repair that yielded the conclusion under "Problem Signature 07: Bad Driver. The diagnosis & repair details were: "A recent driver or upgrade may be preventing the system from starting." I had done no driver updates or upgrades of any type except for the Nvidia driver in April and Windows updates as required
So I decide to make use of a recent system image, with no issues and with a barebones install of Windows. I did all the Windows updates,installed AVAST and PC boots up to the desktop and freezes. Event Viewer only shows that the PC shut down unexpectedly. I have to reboot. I let the PC sit awhile and start it and it gets to the black windows screen and hard freezes.
I installed a temperature monitor and the cores are running 38-41 degs C; right now I'm running memtest. I also did the .Net framework repair because my PC seemed to slow down after that update. I have no hardware attached to my desktop now other than keyboard and mouse. Everything else has been removed. If I am able to get the machine to run, it does so without an issue. I haven't re-seated any of the components yet. The status of my hard drives appears to be "healthy".
I would appreciate some assistance about what to do next. I am stumped about what could be causing the freezing. Thanks.
