I am not able to boot into windows. I get to the Windows loading screen, and the computer doesn't start. It apparently is not liking my overclocked computer all of a sudden, which was working fine in Windows 7 for MONTHS! I did not change the clock speed. It was still the 3.2Ghz for my Q9450. The ram is set on auto timing. Disabling or enabling EIST and C1E doesn't help. The computer boots just fine at the default clock of 2.66Ghz or when I revert to before the update. The computer was booting just fine before that stability update.


Specs of computer.

So let's recap: when you don't use the hardware in a way which pushes it outside its design envelope, then everything is fine. But when you do overclock, then it all goes belly-up.

Hmm.

Disable the OC, boot, then...

Option 1 - rollback the update and repeat orig OC settings.

Option 2 - keep the update and re-do a new set of OC settings.

I definitely understand this, but the OC was working great in Windows 7 for months, the update seems to have,for whatever reason, made 7 not boot with my OC.

Kudos for absorbing my pre-caffeine "I-was-woken-prematurely" customer service manner without flinching

Because of various inter-dependencies, updates like this one tend to bring a whole heap of reworked code with them. You can see from the list of what's included in the update that there's like at least a dozen new files.

Their processing and memory requirements will be subtly different to the executables they've just replaced. In some cases, that's sufficient to expose flaws in underlying hardware. For example, if memory address "8" is unreliable but the code only ever uses 1 through 7, then you can go for years without encountering a problem. Now change that code to use 1 to 3 and 6 through 9 and - boom!

Despite Antman's optimism (@Antman: thanks for being nice for me ), I don't think you've got much choice - you have to revert back to known-safe (non-OCed) settings. Every update from now on which includes any of those files is likely to include most or even all of them, thereby bringing with it a repeat of the problem should you choose to install the update. Therefore, a reworked version of "Antman's Options" would look like this:

Option 1 - Roll back the update and stay away from any and all future updates involving those files, at least until SP1 (and perhaps even afterwards), in order to protect your ability to OC.

Option 2 - lose the OC, install the update, and have a more stable and safer OS.

I think I have pig flu. My sudden sense of mortality has tempred my broadened my world view and tempered my tongue. Thank you, acidic one, for giving detail to the obvious.

I hope you feel better soon. The whole situation has me quite concerned for my family.
