Its 8am.. I stayed up all night working on this thing (first time building PC by myself)
I had a PC already working, I just upgraded it with a new mobo, graphics card, and processor.

Power supply worked before I swapped parts out. I checked the one checklist troubleshooting thread about no startup. I went through all the steps. No luck.

All my cables are connected as far as I know. I checked pretty thoroughly.

One thing I think could be the problem is: with my original parts, I had to use the reset button to turn on my PC, as I guess the power switch doesn't work or something. I've always used the reset switch to turn on my PC since it was built roughly 4yrs ago by my dad n his friend.
(Basically, I think he put the reset switch into the power spot on the mobo.)

I tried putting reset switch into power spot and vice versa, no luck..

Only thing I haven't ruled out yet is that. So if I could rule out that it isn't my case's fault, then ill have no clue why the PC is not booting up.

help would greatly be appreciated :/ I'm tempted to just get geekaquad or something to check it out.. :c
This is my last hope haha Idk what to do :/

Specs are:
Geforce Gtx 660
Gigabyte 990FXA-UD3 mobo
Cooler master RP-600-PCAR (600WATTS I believe)
Amd fx 6core 3.5ghz fx6300 socket am3+
4Gigs ddr3 ram

Well you can always try simply connecting the 2 pins for power on the motherboard using something that conducts electricity, like a screw driver or something. If it boots up it's your case, if not then you probably are missing something.

The most common thing would be the extra EPS connector for the CPU, located between the CPU socket and the backpanel connectors.
The older models of your PSU doesn't seem to have an 8 pin connector for it, only 4 pin. So make sure that is connected and connected to the right 4 pins by the CPU. Usually only 4 will do and 8 is only needed if you need a lot of power, but that 'may' be the issue. Newer versions of the PSU have all 8 pins.

But the psu is what i would expect to be the culprit. If it indeed turns out to be so, checkout newegg's deals on PSU's this weekend for Seasonic S12II 750W ( 79.99 + 20MIR ) and Corsair HX750 ( 109.99 + 20 MIR ) for example.

Have you connected the wire of power button to the motherboard. There would be wire from the front power button . I cant particularly memorise but it needs to be connected somewhere near bottom . If you purchased a mobo . You would have got a manual . Read it thoroughly . Or the manual of the cabinet.

Could u elaborate more on how I could start it up without using the power button?

My power supply was working roughly 6hrs ago and everything was fine. So I feel it shouldn't be a problem now. And yes I have the CPU connector socket w/e plugged in with a 4pin cord. It doesn't fit in the other 4pin side of the 8pin CPU power connector so it should be in the correct 4 by the CPU

And yes, divyanshu, I've tried the power switch cord from the front of the case and plugged it in the pwr switch on the back of my mobo. It didn't work. I've read thru the manuals and know where those front case cords go but the problem is I think my case has a faulty pwr switch cord. My dads friend somehow made it so the reset button, on the front of the case, acted as the power button. So the real power button had no use. I'm guessing he pit the reset cord into the power switch socket? But it didn't work for me

The powerswitch in basic just connects the 2 pins when you press it, if there is indeed some problem there with the cabling. You can connect the 2 pins manually as I said earlier. Basically just connect the pins 6 and 8 i believe they are with a screw driver or bolt and the computer should start, as long as everything is hooked up and the power turned on from the PSU.

I caved and took it to a local PC repair shop. Turns out I had a floppy disk cord from the power supply, plugged into a system fan spot..shortcurcuits the mobo so it doesn't start...its running now haha but thanks for the help people.
I guess I gotta pay more attention to things that don't need to BS plugged in, ESP. In the wrong spot!
