WinXP PRO installation freeze on logo

hoping someone can share some light on this problem.

it started on sunday late evening. when i switched on my desktop computer,when it reaches the windows logo it crashes/freeze.it takes about
10 reboots before it loads as normal.after some hours of use,the computer will crash thus going thought the whole reboot process.i thought it could be a software problem,when i first install xp i did not choose the clean from fresh option.so i decided to reinstall xp but this time as a fresh install.but again i am having the same problem.before installing when it
reaches the windows logo it just crash/freeze.another 10 reboots then it starts the windows installation,but shortly it crashes again.

if you require further deails,please let me know.
