computer cannot hibernate/standby after being on for some time

I have 2 computers having similar problems, but for each there is a
peculiar scenario.
First, I have a desktop with some of the most recent hardware installed,
such as AMD 64 X2 4400 processor, Geforce 7800, X-Fi Xtrememusic, ASUS
A8N-SLI premium motherboard, etc. The computer can enter standby at anytime
with no problem, but not for hibernation. Here's the catch: I can enter
hibernation if I do it right after the system boots up; on the other hand, if
I leave my computer on for some time, it won't enter hibernation. When I
click on Hibernation on the Shut Down menu, the screen turns blue, showing
Preparing for Hibernation then Hibernating. Right after that, the screen
turns black, but there isn't a screen that has a green status bar below
showing the hibernation progress. Instead, the screen flickers (while my
monitor shows "No Signal"), then returns straight back to my desktop. Now
when I access the Shut Down menu, the hibernation option is disabled.
Second, I have a laptop, which never had a problem with hibernating and
standby until now. Same as my desktop, the laptop can enter standby or
hibernation without problem if done right after boot-up. If the laptop is
left open for a while, the standby or hibernation progress will be stuck at
Preparing for Standby/Hibernation and never go on. I will then have to shut
the laptop down with the power button. I think this problem may have to do
with network configurations, since I just added a PPPoE connection to my
Internet Connections.
I have tried many things such as checking drivers, but nothing works. The
trouble is that there is no way of telling "where" in the system is wrong.
If anyone has a similar problem, post here; if there's a solution, post too.

The most common problem that I've seen with Standby and Hibernation is
corrupted video drivers.

Try using an "video driver uninstaller" to remove all traces of your video
drivers. Then install the latest WHQL certified version of the video drivers
for your video card.

FWIW, I suspect that the PPOE connection is causing this with some sort of
"stay alive" feature that may conflict with the video drivers.

For the laptop:
I don't think video driver is the culprit because I've been using the same
driver for several months, and the computer does standby & hibernate
successfully until now. As for the PPPOE connection, I tried disconnecting
then disabling the connection before I standby/hibernate, but it doesn't
help. I suppose there is a more aggressive method of shuting down PPPOE? Or
could it be a registry conflict?

For the desktop:
All right, I will try uninstalling then reinstalling the video driver to see
if it will work. It's so strange that the computer CAN standby/hibernate if
it's not turned on too long.
