    Operating system and BIOS doesnt launch.

    Hi guys since this year I have a problem with my PC , sometimes after a start my operating system (win10) and BIOS doesnt launch, my PC is working all the funs are running and so on.. but the screen is black and both keyboard and mouse are off, and my PC can be in that state for hours. In order to launch my PC properly I have to power off and power on multiple times , and after many restarts my PC will launch normally with WIN10 and BIOS loading on. Any solutions to that problem?. Im listing my PC specs below. I tried BIOS update, didn’t help.

    intel i7-6700
    gtx 1050ti
    16GB RAM
    Motherboard - ASUSTeK STRIX Z270G GAMING

    Missing from the parts is the most important component of all, what is the brand and model name or number of the PSU and how old is it.

    What speed is the RAM and is it one 16GB stick or two 8GB sticks.

    What you describe as happening could be a bad power good signal between the PSU and the MB.

            The RAM is not appropriate for your CPU, Intel state here up to DDR4 2133MHz/ and if you have XMP enabled the RAM will get auto OCd past what the CPU can handle and the PC will at some time become unstable.

            The fact that you mention the PSU being new may suggest that you had the problem before you replaced the previous PSU but sorry to say that the replacement PSU is so bad that it is rated as – Tier F • Replace immediately

            Suggestions as a starting point;

            Make sure that the Windows Power Plan is set to Balanced and nothing else, Ultra and High Performance are a form of overclocking that is known to cause stability and overheating issues, the setting should only be used for gaming type notebooks that have a discrete GPU that needs the extra power.

            Restore the MBs default factory settings in the BIOS, they are sometimes listed as one of the following " factory defaults" “most stable” or on newer boards “optimized” please note that if you have both the “most stable” and the “optimized” options in the BIOS you should choose the most stable" option as in this instance the “optimized” settings are a form of overclocking that can cause instability.

            Save the new settings, exit the BIOS, restart the computer, test by using the computer as you normally would, post back with an update once you have done this.

                Well I remember many years ago my pc was crashing while I was playing games and in order to fix it I had to download a control panel for my MB (AI Suite 3) and through that download the newest drivers, now in order to optimize my BIOS in a different way I have installed, the new ASUS software called MyASUS and there I have an option to upgrade my BIOS and every other drivers directly, so I will use that one for future. I’ve been using this RAM with that CPU for at least 5 years. I hope the problem is not there. If nothing would work I’ll just replace the CPU and Power Supply. I guess those are going to be the main problem. Thank you so much for helping me if anything I will come back here so seek more help.

                        100% do not replace anything at this time, there is zero proof that anything actually needs replacing.

                        Please do as was asked and then post back with an update and if needs be we will go from there.

                        Just don`t and for as to why is explained in my canned info below;
                        Once Windows has been installed, you install the necessary drivers for the MB and other hardware and then leave well alone, drivers should not be allowed to auto update and you should never update any driver/s unless the new drivers are intended to resolve a specific issue that you are having, installing new drivers unnecessarily can actually cause you the very issues that any new drivers are intended to resolve and uninstalling the new drivers may not resolve the problem/s that installing the new drivers has caused.

                        Depending on priority it can take many months before the driver provider releases any fix and depending on the age of the hardware or software concerned they sometimes do not even bother or may have already announced an end of support.

                        The exact same policy applies to the BIOS, do not update it unless it is advised by the manufacturer of the hardware or alternatively if it is to allow for a CPU upgrade.

                        [COLOR=rgb(184, 49, 47)]Updating things for no reason has a 50/50 chance of bricking your computer, don`t gamble unless you can ( A ) Do without the computer ( B ) have loads of spare cash and can buy a new one with no problem or ( C ) Both of the previous.

                        We are tackling the easiest things to do first so as to hopefully avoid you having to open up the PC.[/COLOR]

                            Windows Power Plans is set up on balanced in case of MBs factory setting everything is in default I’ve never changed anything there and I checked everything out of course, the problem is that my PC can launch normally for 10 days straight and for 1 day its gonna have this problem and this is happening like that since the beginning of the year, so in order to realize if that problem is gone I would have to wait a longer period at least couple of days.
