Windows Home Edition not booting up anymore

[Shawn]

My friend restarted his computer cause something was
slowing it down and creating extremely long periods of
freezing. When it turned on, it showed the graphics card
info (normal) and went to an intel logo screen (normal),
but then he got this message:

Intel(R) Boot Agent FE v4.1.09

11D6 AD28 0030D3000E76
DHCP..../ (this / is constantly changing like it's
loading or searching for something).

We let it do whatever it was doing, and it ended up like
this:

PXE-M0F: Exiting Intel Boot Agent.


Boot Failure, System Halted

We tried again, but tried pushing buttons this time (to
perhaps bypass it). The only button that does anything is
escape, which gives us the message that there's a boot
failure: System Halted as above, just a little different.

Any help would be greatly appreciated.

Is the PC plugged into an always-on network? The DHCP bit is where your PC
is trying to acquire an IP address from the network - this will fail of
course if you have no network connected.
Try pressing F8 during the boot up and selecting no network or safe mode.
