couple of things that tell from the log u posted.. log indicates that windows tried to access pagefile memory using kernel process IRQL that was too high.. drivers that use improper addresses USUALLY cause this error..
also, atapi.sys mentioned somewhere, and my take is you've updated CD drive firmware or installed a new drive or have DAEMON Tools or Alcohol 120% installed, doing any of these things results in atapi.sys being locked & preventing windows from backing the file up in an XP system.
OR for whatever reasons, improper shutdown, lost power, data corruption or million other things.. i would recommend start running windows setup from cd, reach to the part where you can run RECOVER CONSOLE, and use the command : bootcfg /rebuild
restart
if that doesnt work, try going to recovery console, use command: REN BOOT.INI BOOT.OLD
it will replace booting sequence file and will popup an error saying No BOOT.INI file found, using C:\WINDOWS default and the computer shall continue booting...

XP Repair install
Please read carefully and make sure you followed the warning links before initiating the Repair Install. You can print a text version for reference. repair.txt
Boot the computer using the XP CD. You may need to change the boot order in the system BIOS so the CD boots before the hard drive. Check your system documentation for steps to access the BIOS and change the boot order.
When you see the "Welcome To Setup" screen, you will see the options below:
This portion of the Setup program prepares Microsoft
Windows XP to run on your computer:
To setup Windows XP now, press ENTER.
To repair a Windows XP installation using Recovery Console, press R.
To quit Setup without installing Windows XP, press F3.
Press Enter to start the Windows Setup.
To Repair Install, press ENTER
To setup Windows XP now and Repair Install , press ENTER. do not choose "To repair a Windows XP installation using the Recovery Console, press R", (you Do Not want to load Recovery Console). I repeat, do not choose "To repair a Windows XP installation using the Recovery Console, press R".Accept the License Agreement and Windows will search for existing Windows installations.
Select the XP installation you want to repair from the list and press R to start the repair. If Repair is not one of the options, END setup.

IF THAT doesnt work, i will recommend hardware/touching physically... for your computer to boot, it requires video (monitor) and keyboard... open up the computer and take out EVERYTHING else (sound, network, cd drive connection, keep hard drive) and restart..
IF IT GOES through, put the mouse back, restart...
then put cd drive back, restart..
then sound, network (or wireless).
if they are not physical cards connected to your computer, try disabling them from the bios (if it lets u).. try maintaining the order..
my feeling is it could be corruption occured within windows (it should ALWAYS let u start in safe mode) and swapping physical components tend to reset these things..
