Windows 7 freezes [CRASHDUMP included]

-memtest pass, no errors.
-cleared the old drivers and re-download and update nvidia drivers.
-updated asacpi.sys as mention early on.

Things seems to be running back to normal. thanks again for your help guys.

I still don't understand why out of the blue on wednesday night It been 10 months since I installed W7.

Well I'm happy how it turns out.

I'm very happy to hear that how thing turn out and I bet Tews is very happy too!

Well, as I mention the ASACPI.sys date from 2005, driver that more than 2 years old are potentially causing BSODs and ASACPI.sys date from 2005 is guaranteed for causing BDODs. and also, who know in a nice day, when some of your application get interact with the old driver and causing BSODs.

Let us know if you need more help in the future
