Ok, so I RECENTLY got all my parts to build my COMPUTER except the cpu, so I decided to build it anyway before the cpu got here... But, before I had finished the build I tried to boot my pc to TEST ( I only had the ram, motherboard, psu, fan case, hdd and optical drive.) the the power button flashing , the case fan was working.
After I placed the graphic card and the wireless card I tried to boot it again and I got the same results...After I place the cpu power CABLE I tried to boot it again but it didn't work... I'm worried that I may have damaged something in the process.. Is there any chance that this may have happened? Or it just didn't boot because I didn't have the cpu in place? Please Help ! I´m really sad , the componentes are all new A PC will not do anything without a CPU installed...My pc has turned on .... I only want to now if didin´t damaged anything   I can't think of anything getting damaged but in the future TAKE more care rather than just guessing and turning things on.Yes I know that was a stupid thing :$ , You really think that didn't damaged anything even if before the pc was starting and after connecting CPU power cable ( Without CPU installed ) won't turn on ?I was thinking  you would tell us
-  the thing started to work
- without the CPU,
but was  very slow. 

That question has come up before, the OP is not the first.
If I power a motherboard without CPU/RAM...
basically what I meant is that I turned on the pc to test the components making the CPU , which was going well until I connected the CPU power cable and the pc after that did absolutely nothing , before putting the CPU power cable had connected showing rotating the fans . I hope can anyone help me , I am really worried about my pc componentes . I want to know if is anything damaged or not ? ;( As I have said, I doubt anything is damaged however the only way to tell for sure is to try the CPU when you get it.ok thanks , I will get My cpu by monday , if U dont mind and if I have any problem I can message u ? No...
