how do I return to Vista?

Is there anyway, to turn off Windows 7 and go back to Vista without a hard drive Format?

I bought Winows 7 because, I would get a blue screen crash every day with vista and this error code every time I wanted to do a windows update.

With Windows 7 I still have these problems, a blue screen crash daily, but with more lag then vista.

Also, with Windows 7 if you change the screen resolution, it just shrinks the viewing area on your monitor. I don’t want it to shrink the viewing area, I want it to lower the quality to reduce lag in certain games.

I would like to return to vista I am wondering the least painful route for this?

yes, it was an upgrade from the already installed VISTA from the OEM

oh, thanks for the information.

No one can tell me the problem, my whole system freezes up 10 mins after start up, I reboot and its fine for the rest of the night. I go though this every day. Sometimes it goes to the blue screen of death, and I get error codes, I called Dell they say them error codes are with the "operation system" it also says something about clock intervels not matching so shut down to stop damage.

but lets start with the easiest of my problems then since I cant go back to Vista. I want to lower my screen resoluation but still fill the entire monitor. With Vista you changed down to say 1360 x760 and it was less quality but still filled your monitor with 7. it just shrinks your viewing area. Any way with windows 7 to lower the resoluation and still fill the screen?

I would not think my specs has anything to do with specific windows questions like setting screen resoluation or a operating system crash/blue screen.

but, 4850 ATI card
6 DDR3 ram
i7 intel chip
standard hard drive
its like the new dell stuido machine

Nobody can help you with your problem unless we know exactly what we are looking at. System specifications assist in that.
