Hello, I built my PC late last night, so didn't get chance to really test it last night, anyway when I come to test it this afternoon in my 19 inch tv via HDMI it just wouldn't boot and there was no video output at all. I fixed this problem by unplugging the PCI-E lead from the gpu and for some reason it did boot and show video out put. However I turned it off and went to install Windows 7 and then I couldn't turn it on when I flicked the PSU switch there was just a green light flashing on the Motherboard and it won't even turn on at all.

Things I've tried after a little bit of research:

.Removing the PSU and all cables and putting it back in and hooking everything back up.

.Removing the Ram and re installing it.

.One ram stick to see if it would boot up rather than 2.

And none of these have worked at all . Any help Would be highly appreciated as I'm frankly terrified something has happened, I've attached some images below of the Motherboard and cables.

The build:

Motherboard:Asus H81L-Plus

CPU: I3 4330 3.5GHZ

GPU: Msi radeon r9 270 twin frozr edition

Case: Corsair Obsidian 250 d

Ram: Hyper x 8gb

PSU: Corsair cx 430 w



Cheers,Jack
 
One question.

Did this PC work at all last night? but you just did not have time to do a proper "test"
 
How are you turning it on n off? Try swapping front case power and reset wires over and start pc with the reset button,just to rule out a faulty front panel power switch
 
if it did work it should still work, Have you changed anything?
unplug every thing HDD's, Ram, Gpu the lot. reset Bios and start putting parts back in one at a time and boot until you have a problem(if it boots at all)
 
If you plug a GFX card into the board, the onboard GFX is probably disabled.

So move the monitor connection from the board into the GFX card.
 
Have no Idea and I've had to build it while standing on carpet so knowing my luck I've probably blew something, that's 500 gone down the pan ffs!. However I was careful while handling the parts my finger accidentally touched the back of the gpu sometimes while plugging stuff In but I doubt that's why.

Tried unplugging everything, putting it all back in and it's exactly the same :(
 
I doubt its due to that

flashing green mb light points to a power issue imo,could be cpu related idk

have you checked cpu socket for any bent pins? and have you tested by turning on the pc with swapping power and reset mb wires over and start it with reset button?

also try a long cmos/battery removal 10-15 minutes then put back in n try

Click to expand...

Which wires you mean? completely new to building :(
 
theres a + and a - wire at the bottom of the mb that connects to the case power button and same again for the reset button

take all the wires off and just connect the reset +/- to the mb power +/- pins and start pc with reset switch

if no joy put them all back to how they were originally
