Hi Sharon,
It's a desktop, and I've checked all the settings under
control panel. Do you have any further suggestions?

What power scheme are you using in Control Panel> Power Options?
When you say that it goes through the whole boot process again, is it
starting over from POST or just from the welcome screen?
If just from the welcome screen, uncheck the box next to Prompt for
password when computer resumes..." If using a screensaver, uncheck a
similar box in the screensaver settings as well.
If it's going through the entire boot process (POST, loading Windows and so
on) then you'll need to dig deeper. Look in Event Viewer for any errors
noted at the time the system goes into standby or when you try to resume.
Am hoping you can find a clue referencing a driver or a program here.
If no luck, try disabling all running programs including those that run in
the background. Put the system into standby and try a resume. If
successful, then there is a program incompatibility that you will need to
track down.
If not successful then a driver or device is not complying with the rigors
of standby and resume. What drivers were updated recently? What hardware
was added since the machine hibernated correctly? May need to check with
the hardware manufacturer for a newer driver that is more standby-friendly.
