No offence but I find that strange thing to say considering I had more BSOD's than I've had hot dinners until I updated my BIOS. That was a couple of weeks ago and I've played games, while downloading 3 movies at time and given it a real workout at not one single crash or even a hint of one since.
I'd say and I am guessing, that a lot of these BSOD's on windows 7 are caused by motherboards with a BIOS not built to cope with conflicts caused by some drivers that are part of windows 7.
Way too many people are having crashes that wen't having them, before Windows, 7 to it be RAM or Hdd's all of a sudden gone bad from Calafornia to China.
I ran the infamous Memtest and had errors so replaced my RAM and still had errors but after I flashed my BIOS.. no errors.
I am bamboozled why people think an update to a BIOS is any less important than updating a driver. Surely the companies that launch them do so with good reason.
Maybe I'm too suspicious but it's not that companies are going to advertise the fact if you buy a certain motherboard and install Windows 7 that the BIOS won't run it properly. That would soon get around and the sales on those motherboards would fall through the floor.
I'd say it the first thing people should look at if their machie was running well before upgrading to Windows 7 not the last. As you say as long as they can back up their data etc.
However it's only my opinion and there's a lot of people on here know a lot more about computers than I do.
