Components of Self-Build PC (all brand new):
Motherboard: ASRock X99 Extreme4/3.1
CPU: Intel Core i7-5820k [PURCHASED FROM FROM A PRIVATE SELLER ON EBAY, UNOPENED PACKAGING THOUGH]
CPU Cooler: CoolerMaster Hyper 212x
GPU: EVGA GeForce GTX 950 SC (NVIDIA, Superclocked, 2GB, GDDR5) [PURCHASED FROM FROM A PRIVATE SELLER ON EBAY, UNOPENED PACKAGING THOUGH]
RAM: G.SKILL Ripjaws 4 Series 32GB (4 x 8GB) 288-Pin DDR4 SDRAM DDR4 2400 (PC4 19200) Desktop Memory Model F4-2400C15Q-32GR (quad channel)
HDD: Western Digital WD10EZEX 1TB SATA lll Desktop SATA Drive - Blue
SSD: PNY CS2211 2.5" 480GB SATA III MLC Internal Solid State Drive (SSD) SSD7CS2211-480-RB
PSU: Corsair CX600M (this is semi-modular, although tbh l have used just about all the cables it came with)
DVDRW: Samsung SH-224FB/RSMS 24X Internal DVD Writer with SATA
Monitor: BenQ GW2765HT Black 27" 4ms HDMI Widescreen LED Backlight LCD Monitor IPS
The PSU is connected to the DVDRW, the SSD, the HDD, and the GPU.
The GPU is connected to the PCI 3 lane (PCIE 1), the first PCI lane on the mobo.
The HDD and SSD are connected to SATA ports on the mobo.
The DVDRW is connected to the USB 3.0 header on the mobo.
The PSU is connected to the 24-pin ATX Power Connector (ATXPWR1) on the mobo.
The PC would not output a signal to my Benq monitor (nor a second monitor l got from a charity shop, connected via an adapter) at any of the following stages (even though l have a self-booting Linux disc in the optical drive - there are no POST error noises):
(1) First, the PC would power up, abruptly cut out after about 4 seconds, then power up again and stay on.
(2) Then l changed the GPU connection to the PSU by removing the twin molex cables (required for some PSUs l think, it was actually compatible with my PSU anyhow) connected to the GPU's 6-pin (?) connector, and l connected the PSU directly to the GPU via the GPU's 6-pin (?) connector. Then, the PC would power up and stay powered up.
(3) Then l attached the PSU 8-pin connector to the 8-pin ATX 12V connector on the mobo, near the CPU (in *addition* to the existing PSU connection to the 24-pin ATX Power Connector on the mobo), and the PC went back to powering up, staying on for about 4 seconds, before abruptly cutting out and then automatically powering up again and this time staying powered up.
Please could somebody advise on what has gone wrong. I feel that either something is DOA, or more than 1 thing is DOA, and / or l'm just doing something wrong anyway?
Please note: the HDD and SDD are blank.
EDIT: Just remembered: I don't have an internal speaker, so that'll by why l hear no POST beeps. Could l get POST beeps via external speakers?
