New stability update from MS. I haven't had a freeze since the day before yesterday. Will keep you posted.
Interesting, because my system STARTED freezing about 5 days ago.
My Win7 History:
I got W7 on release, along with a shiny new Intel X-25M SSD drive. Had trouble getting W7 to finish installing on the new drive, tried several things, and eventually removed the SSD and installed on my old HDD and system ran great until I reinstalled the SSD as a slave drive in the system. Freezes began again.
I tried all the suggestions from Intel's site, and eventually gave up, asked Intel for a replacement or refund, which they refused by the way, so I own a nice $240 paperweight.
System ran flawlessly on my old HDD for 2-3 months, up until late last week or so I think it was.
My system has begun freezing for no apparent reason. I booted it up last night, left it sitting at the desktop to test it, and when I returned 15 minutes later, it was frozen.
Other times it's frozen at the W7 booting logo, another just after getting to desktop and opening my Windows Live Mail.
Before these past few days I could run and leave my system running for days without a single issue, including playing and hosting Call of Duty Modern Warfare games.
So I will keep tinkering until I find a solution, and keep reading here for suggestions of things to try.
Good luck everyone, let's get this issue resolved.
PS - I am running 2 new Dell Optiplex systems at work with W7 Pro x64 on them, and they have been flawless so far. Only been 2 weeks so far, but all has been good.
