This my first time using this forum so i am sorry if this is posted in the wrong section (please move if so..)
Here's whats happening:
When i press the power button, the LED's and Fans start up, you can here the HDD's being accessed but then it cuts all power.
If you leave it, it will redo this again (takes about 2seconds) but on the third attempt it will stay on but not go to POST.. no beeps, nothing.
What i have done:
01: Connected the green and black wire on the the ATX plug (from psu) = psu stays on.
02: Manually jumped the power switch on MOBO with paperclip = same fault as above.
03: Disconnected all cards & drives = same fault as above.
04: Rotated the ram, trying 1 at a time = same fault as above.
05: Removed MOBO and PSU from case = same fault as above.
06: Disconnected the 4pin cpu pwer plug = Power light flashed on then quickly off for a mili second.
07: Ordered a new more powerful "Named psu"

Im thinking as ive bought a "Unnamed PSU" that its the PSU that it as fault, i have ordered a Corsair TX650 to replace this but until it arrives i wanted to test everything else to make sure its just a case of - replace PSU on arrival and all systems are go.
I built the system myself and it worked like a dream for 2 months... until yesterday morning when i turned it on and found this fault.
Any help, thoughts, suggestions would be greatly appreciated - Thank you in advance
