get a \"boot screen\" (download from style xp)
boot in to safe mode. press f8, find the file ntoskrnl.exe
(in windows system 32 i think)
copy the one you downloaded (itll be the same name) and copy
& paste into folder with ORIGINAL one in it. (windows system 32) Make sure you use SP1 \'ntoskrnl if you have SP1 installed and vice versa..
Itll say \"do you want to replace nostkrnl with this one..blah ..blah
yes. reboot in normal thats it\"!
