XPS M1330 freeze while running on windows XP professional

i have DELL XPS m1330 Laptop with windows vista home edition installed as factory setting. its working fine. but i wanted to install windows XP and same time i wanted to preserve my Windows vista copy too. so i bought a new internal HDD and just replaced the original internal harddisk with new one and installed windows Xp Professional on this new HDD. i have successfully installed windowas xp and all the necesarry drivers  but now problem is after working for few mins my laptop just freze.i have macafee installed and it doent show any viruses or edware or any malacious stuff.so i guess its some software issues with my WINDOWS XP copy or touchpad problem.i tried to work in safe mode and touchpad and keyboard works fine in safemode but not in normal mode. attaching a mouse doesn’t work either. I even reinstalled the WINDOWS XP quite a few times,but same problem persists it works for a bit then doesn’t work again.

i guess as my system works fine with windows vista and even with windows xp in safe mode,so  it shouldnt be a hardware problem.

i get problem when i work in windows Xp normal mode, so i guess should i try with different copy of windows XP ?what should i do?
