Hi. Few days ago while i was on my pc (youtube if i recall well) my pc sudenly dramaticly slowed down, needed 30-40 sec to do simple task as open my computer or anything similar. I have turned it off (needed to go so had no time to check what was wrong) and 3-4h later when i tryed to turn it on, It does turn on but displays nothing I seen fans running on cpu graphic card and PSU. I did take out battery, tryed to unsocket re-socket RAM and reconected all cabels. After few try's it stoped turning on completly and after i removed and returned cabels again it started turning again (still no display). I got my long awaited new Motherboard and CPU (ordered then some 3weeks ago) and it gives same results with it (still need to replace RAM as I had DDR2 and new ones are DDR3). So pls anyone know could actual problem be my PSU? Or it could run normaly when i get my RAM.

I' am sorry for my bad English its my 2nd language i' am still trying to learn.
