Completely new build with the following components:
Mobo: MSI Z270I
CPU: i7-7700K
HSF: SilverStone AR06
PSU: SilverStone SX500-LG
Case: SilverStone Raven RVZ02
RAM: Avenir Core 2x16GB DDR4 PC4-19200C16 2400MHz CAS 16-16-16-36 1.20–1.30V
SSD: Intel 600P (M.2)
GPU: Palit GTX 1060 (6GB)
With everything installed and connected, when I power on all the fans start turning and the cosmetic LEDs come on, but there’s no beeps from the internal speaker and nothing appears on the screen. The mobo has four debug LEDs (CPU/RAM/VGA/BOOT), which according to the manual will light and stay lit if the component “is not detected or fail”. Of these, the CPU LED comes on for a second or so and then goes out, and then the RAM LED does the same. There are also LEDs for the RAM and PCIe slots that light if the component is present, these are all on.
I’ve tried everything on the stickied thread (http://www.tomshardware.co.uk/forum/261145-31-perform-steps-posting-post-boot-video-problems) with the exception of the last bit involving opening up the PSU, which I’m not confident doing.
Relevant points/questions from going through that thread:
#21 Resetting CMOS: the mobo has a CMOS reset button on the back and a jumper on the board – do these do the same thing or do I need to try both? I’ve only tried the button (no effect) so far, as the jumper requires a jumper cap to short it which I don’t think I have.
#22 Integrated vs video card: I’ve tried both the integrated graphics and the video card with two screens and as many different connections as I can, which was in full: HDMI from either integrated or video card to either screen; DisplayPort from either integrated or video card to one screen; DVI from video card to one screen. (This was before I got hold of an internal speaker and found out I wasn’t getting a POST beep, but I’m including it for completeness.)
Breadboarding: I followed the sequence with the following results:
With only the CPU and HSF connected, I got the three long beeps, and the RAM debug LED came on. I then added RAM and booted again, and got no beeps (i.e., back to the situation above but with the mobo out of the case).
According to the text, "silence indicates that the RAM is shorting out the PSU (very rare).” Does this means the RAM is defective? Or the RAM slots? It also says just below “an inadequate PSU will cause a failure here or any step later” – so presumably the silence could also be because the PSU is defective? (As I said, components are obviously getting power, but I guess it might not be delivering enough power?)
What is more likely – PSU or RAM – and is there any way to tell beyond just swapping them out?
I don’t have any known working components to swap with (before building this desktop, I’ve been using laptops pretty much exclusively for years.), so it would be a case of returning the components.
Sorry for the long post – I’ve probably included irrelevant details, but I was trying to cover everything. Any detail that’s missing, please ask.
Any help is very much appreciated!
(PS Although it’s my first time building from scratch, I have replaced RAM, HDs, graphics cards, etc before, so I’m fairly confident that everything is connected correctly and something must be faulty. The one place where I had some doubt about the connection was the GPU – the nature of the case means that it connects through a couple of extenders, but since testing without the GPU connected at all hasn’t changed anything, that can’t be the problem.)
