I have bought new parts for my PC. (PSU, CPU, RAM and Motherboard)




I bought the RAM, motherboard and CPU first, and all was fine, but as I plan to get a new graphics card soon, I needed a new PSU. I bought a new one and put it in, but now sometimes when i turn on the computer, it comes on for a second, then turns back off again, then back on etc. It does this multiple times, then eventually boots up. (It appears it does this a different amount of times every time)




When this happens, the fans come on, then go back off again. It is the same with the Power LED light.




There is no problems when the computer is running though, it doesn't ever crash or turn off once it is booted.


 




Any ideas why this is doing this? I think it might be a dodgy PSU but I don't want to take it back to get it replaced, only to find I still have the same problem.


 




Thanks in advance.
