Computer Unstable!!

Hi all!!

My computer is getting verry unstable after i bought my new motherboard and a new powersuply!! sometime's the pc just restarts or the explorer.exe crashes and the wallpaper just dissapears after a restart, and everything gets black. There are no viruses, and no adware, i checked all software and hardware, and everything seems to be working allright!!!

Is there something i missed???

 

what is your old and new power supply? (old and new). Sometimes, a lesser brand at 450 watts can be worse than a better brand at 400 watts.

 

I’m having a problem regarding my windows xp professional. My taskbar and start menu is missing I try to change setting on control panel but still it doesn't work also I can't drag my desktop icons I can click them but I can't move them in a different place I try to use "copy and paste" and "cut and paste" still didn't work! Please help me! This problem is driving me crazy! Please e-mail me at cityofangels1210@yahoo.com. Thanks
