recommend CPU , RAM and MB upgrade

[tweety_piyo]

currently my setup is this

UserBenchmarks: Game 89%, Desk 70%, Work 40%
CPU: Intel Core i5-4570 - 63.2%
GPU: Nvidia GTX 1070 - 103.1%
SSD: Samsung 840 Evo 500GB - 108.8%
HDD: WD Blue 1TB (2012) - 99.8%
RAM: G.SKILL Value DDR3 1333 C9 2x4GB - 50.5%
MBD: MSI B85-G43 GAMING (MS-7816)
monitor : Prisim+ X340

For some reasons my monitor keeps getting no signal at startup randomly.

Did some trial and error and it seems that if i remove some rams the problem seems to go away. hence i feel that the motherboard ram slots may be faulty

So thinking of upgrading the CPU and MB...i mainly use to play FPS games like Rainbow six 6 and surf net. no video editing and mainly light office work

You don't need to upgrade.
Either live with single 4GB ram or go buy single slot 8GB ram.
Performance will drop by a bit around 10% either way.

Full Upgrade CPU + RAM + MOBO will cost you over $500 easily.

will faulty ram slots cause monitor to go into no display? although still can hear that PC starts up fine and can see from my keyboard LCD screen (logitech) that pc has started up ok although monitor says no signal
