First Time Build - Power But No Display

Stever49 · 9 Sep 2013 at 17:12

Hey, I'm building my first pc and have hit a snag (how big a snag I have no idea, might be a misplaced cable or could be a broken component; really don't know). I've assembled it and, baring the power and HDD LEDs, am fairly happy most of it is assembled correctly (could well be wrong mind, something obviously is wrong!). I went to boot it up and it turned on, the PSU fan and CPU fan both whirled into life, but there's no video output.

I'll provide details as and when asked for them, and will provide pictures of any particular areas if needed. Just wanting help trying to troubleshoot the problem as I have a big fear the mobo is faulty/damaged (it's in a new case after the previous one was awful [screw holes that were de-threaded from the start, area of support very flexible, etc.] and in trying to remove it I fear it may have been damaged).

Any and all help very appreciated!

(Should have mentioned, it's inbuilt graphics)

Specs are:

1 x Asrock FM2A75M-DGS A75 Socket FM2 VGA DVI 5.1 Channel Audio mATX Motherboard
1 x AMD A10 5800K Black Edition 3.8GHz Socket FM2 4MB L2 Cache
1 x Corsair Vengeance 8GB (2x4GB) DDR3 1600Mhz CL9 1.5V Non-ECC Unbuffered
1 x Crucial 64GB M4 SSD - 2.5" SATA-III
1 x Seagate 1TB Barracuda 3.5" SATA-III Hard Drive - 7200RPM
1 x Microsoft Windows 7 Home Premium w/SP1 (not yet installed obviously as I can't get any video output)
1 x Powercool 450W PSU - 4x SATA 1x PCI-E

I can rule out the monitor as it works for my other pc. Will try and start working thought that list (going to have to go eat in a second so might be an hour or so before I can start), might need to query a few bits as I go (and provide pictures to check I haven't missed a cable or put the wrong one into the wrong socket, etc.)

Thanks for the ongoing help

Update: Checked RAM and PCI-e seating, doesn't seem to be the issue.

@imb4tman, video cable? Do you mean externally? If so VGA. If not, then I'm not sure what you mean as (as far as I can spot) there's no video cables internally :s

(About to eat, will be back to answer replies in about an hour)

Thanks for the ongoing help

Ok, can I ask what's wrong with the psu?

Stever49 · 9 Sep 2013 at 19:15

Yeah it was defiantly on the VGA input and it says no signal

As far as I can see, no inbuilt mobo speaker (wish there was, then I'd have a better idea if the mobo has bit the dust

)

RJC said:
Have you tried a CMOS reset and is the 4 / 8 pin connected.

4/8 pin? There's a 20 pin (think it's twenty, it's the long one) and there's a 4 pin (labeled ATX12V1) on my motherboard. Is the latter the one you refer to? If so then yes it is connected, I used one of the PSU cables that's 8 but splits down into 2x 4 pin connectors for it (which would fit with my understanding of it either being an 8 pin OR a 4 pin). Sorry if I'm misunderstanding you, first time really dealing full on with a mobo instillation so it's the on area (that and PSU) that I'm quite naive on!

CMOS reset, that's when you remove, and then put back, the mobo battery right? (Just want to check before I do that!)

@Coxysis

I shall try that once I try the above

At the moment there's only 1 USB device connected (a wireless adapter for the keyboard and mouse), so once I try the above I'll give that a go

Update:

@RJC

Actually scrap what I said last time, I've just removed the battery as I felt that was easier for me to work out! Will leave it out for a while like instructed, replace and see what happens.

I did try it without it and it didn't work, but can't harm trying again

And yes it is wireless card

Stever49 · 9 Sep 2013 at 23:09

Update:

Tried again without the wireless card, no joy.

Likewise I reset the CMOS without any results.

Also removed the usb devices without getting video out.

Referring back to the speaker question from earlier, whilst the mobo doesn't have a built in speaker it does have the pins to allow one to be attached. I'll pop into a store tomorrow if I have the chance and pick one up. Would that rule one way or another if the mobo is the issue (i.e. if there are no beeps it's defiantly the mobo, etc.)?

Thanks for the reply

I think I have one knocking about oddly (or like I mentioned I can buy one fairly cheaply I do believe). Just posting to say I am still trying to deal with this issue, just been absolutely swamped today so picking it back up tomorrow on my quest to make this damn pc work!

I've said it a few times but seriously thanks to everyone who has been trying to help, you have no idea how much I appreciate it! It's a first time build... and it's for my parents... and I go back to Uni next week so will be having to do a trip home to sort it at a later date. The more I get sorted now (even just determining if a particular part is faulty) the less stressed I'll be!!
