What to do after updating CPU on laptop

Hi! I've recently updated my HP 6720s CPU. Previously it had Intel Celeron M CPU 530 @1.73 GHz
and now I replaced it by Intel Core 2 Duo Processor T5870 (2.0-GHz, 800-MHz FSB, 2-MB L2 cache).
The problem that I have now is that when I power up my laptop after Windows logo all I have got is blurry image on display and some random dots. Can't see a thing! To bypass this first I have go to Safe mode, then restart it and then it all works fine. If I skip Safe mode part all I've got is described blur on display.

Please help, what should I do? Do I need to install something? I already tried to update Bios, reinstaling Windows and updating all drivers and it didn't help a bit. The problem is still the same,no matter if I run laptop on battery or via power supply. The only solution for normal work is to reboot after Safe mode. Kinda annoying I would really appreciate if someone could solve this.
Thank you in advance!
