i built this system 3 years ago - system specs
CPU i7-4790
Mobo Asus Z97M-Plus
drives - multiple, up until recent Samsung NVMes, a 950 and a 960 plus a few storage drives
ram - G.skill 1600 DDR3, 32 GB
PSU - Seasonic SSR550
OS Windows 7 Home Premium
every few months since new, it would occasionally not get past POST ie freezing on the splash screen and i'd do a hard restart, sometimes on the next boot it would go into windows, sometimes it would take 2-3 attempts. Today i've done multiplle attempts, have left it off, with cord unplugged, tried it with a Recovery disk in the BD tray - it will not boot past POST.
Recent history - i purchased 2 additional G.Skill sticks of ram, identical part # to the first two, 8 GB each bringing it to 32 GB. After installing i found win 7 home premium doesn't support more than 16 GB of ram, so i upgraded to Win 7 Ultimate. After the install i downloaded about 1.5 GB of windows updates, installing 30-40 at a time, and just near the end or the last couple of updates, the system crashed and on reboot i got a black screen with a big red message box with a stmt about "a recent firmware/hardware has this system incompatible, hit OK to move to the next secure boot device"
I made it into BIOS and in Boot settings > Secure, changed the setting to "Other OS" from UEFI Windows Manager and it booted
i went back and finished the update downloads.
Win 7 Ultimate was on two NVMe SSDs (samsung), one was a backup clone - i go into disk management and put the clone "offline" after cloning. I also had two Samsung sata SSDs that had Win 7 Home premium, one being a clone, and i keep both or kept both offline.
Last night i also re-flashed the latest BIOS to the mobo - same as i have probably done half dozen times, only because it had given me one instance yesterday of not getting past POST with one a week or so earlier and i figured it might be a good idea to refresh it. I also cleared CMOS with both the RTC jumper and the battery
This morning i was doing something, and noticed in disk management, after putting the backup clone disks "online" that i no longer had the ability to put them back offline. That choice was not there when i right clikked on a disk. Then the system wouldn't restart a few minutes later after i'd updated a 3rd party software program. I went into BIOS to select the back up or clone NVMe SSD with the same OS, win 7 ultimate and it wouldn't boot with the same red box msg.
So i went into BIOS to boot into one of the Sata SSDs with Win 7 Home Premium, and it would not boot - went into BIOS to change the setting at Boot > Secure back to UEFI Windows, which the Home premium OS had run on for 2.5 years
Then the computer wouldn't boot at all into win 7, not getting past POSt
Any suggestions, ideas etc - thanks in advance
