Safe mode only works =S

Hello i do not know if you can help me but recently my computer has been acting up firstly when i loaded up games the computer froze and i had to restart manually and then after i woke up to a new day and turned the comp on it sounded fine and on screen was the loading xp with the blue bars going along the screen after this it went blank after 10 secounds it comes up with a fuzzy blue or white screen and after says no signal i tryed turning it on again in safe mode and it worked fine but the icons are big and it dont let me do things i want to do i also tryed last good config but also did not work i have come to a "theory" i think that it might be due to a type of virus? so i was wondering if anyone could look at a hjt report and see if anything comes out please help me if you dont think its a virus please inform me so i know.

Thanks in advance for any help given no matter how little
Thanks.
