The BIOS screen freezing points at hardware. The BIOS is not the
highest power state for the computer, so at that point, it
probably is not the power supply. It could be a motherboard
component is failing, or one of the on-board motherboard
voltage regulation circuits is not working right. Since
internal motherboard voltages are not monitored, it is
pretty hard to tell what is going on.

Rebooting in Windows could point to the power supply, especially
if you are in a high power mode at the time. Try running Prime95,
CPUburn, SuperPI, or the like, just as a means of drawing a bit
more current from the supply. If the machine reboots right
after a "loading" program starts, that could point to the PSU.

Have you looked at the voltages in the monitor page in the
BIOS ? Does the screen freeze when accessing the monitor chip
(as triggered by entering the monitor page) ?

Asus Probe could be used to display the system voltages while you
work. See if a reboot correlates with a dip in one of the
voltage rails.

When it comes to some errant behaviors in Windows, it is a bit
tougher to put 2+2 together and get an answer. After all,
gremlins could be malware of some sort.

Backing up the drive is a great idea. You can never be too safe.
But, you may find, that just the act of trying to backup, is
enough to "tip it over". In which case, removing the drive
and taking it to a stable computer for backup, would be
an alternative method.

If the memory was the problem, I'd expect to see more BSODs,
crashes, and the like, as rebooting all the time without at
least some BSODs or nice error messages, is not like a memory.
Of course, if a memory has a stuck bit, in some region of memory
occupied by a "ticklish" part of the OS, anything is possible.
At this preliminary point, I wouldn't be reaching for
memtest86+ quite yet, at least until you run out of other things
to try. If you have more than one stick of RAM, you could try
the sticks one at a time, and see if the symptoms change
at all.

I wonder - is the Registry loaded into memory all the time ?
Maybe if the Registry got corrupted, that could account for
programs acting strange ?
