Quick summary and priorities: this looks like two related problems — unstable system (random restarts, flicker, BSOD) and a missing partition. Start by capturing crash details, then isolate drivers vs. hardware, and only attempt partition fixes after backing up or confirming the disk state. Notes from the thread: correctly points to Event Viewer, 's compatibility check is a good start, and 's driver suggestion is important — treat those as the first checkpoints, then move on to hardware tests.

Immediate, safe checks (do these first)

  • Capture crash info: turn off automatic restart so the STOP code is visible (System > Advanced system settings > Startup and Recovery > Settings > uncheck "Automatically restart") and note the STOP code and any driver named.
  • Check Event Viewer for Error/Critical entries at the crash times: run
    eventvwr.msc
  • Look for dump files in %SystemRoot%\Minidump. Set dump type to Small memory dump if not already set.
  • Basic integrity scans (run from elevated command prompt):
    sfc /scannow
chkdsk C: /f /r   (run on each Windows volume as needed)
mdsched.exe       (Windows Memory Diagnostic)
diskmgmt.msc

Video drivers and hardware to isolate

  • Boot to Safe Mode. If flicker/restarts stop, likely a video or other driver. Do a clean display-driver reinstall (uninstall current driver in Device Manager, then install the latest WHQL driver from the GPU vendor). For stubborn driver remnants, use the vendor-clean option or a removal utility in Safe Mode before reinstalling.
  • Check temperatures, reseat GPU/RAM, and test RAM with Memtest86+ (bootable) and Windows Memory Diagnostic. Random restarts plus flicker can be GPU, RAM, or PSU-related — verify power and cooling.

Missing partition guidance and data safety

  • In Disk Management check whether the partition is unassigned, RAW, unallocated, or the disk shows "Not Initialized" — do NOT initialize a disk that contains data you need.
  • If the partition is present but no letter is assigned, assign one. If it shows RAW or you suspect file-system damage, make a sector-level backup (dd image or image tool) before attempting recovery. Tools like TestDisk can often recover partitions if you cannot mount them.
  • If the controller mode (IDE/AHCI) or RAID drivers changed after install, Windows may not see a volume — check BIOS SATA mode and ensure the correct storage drivers are installed.

Order these checks: Event Viewer + disable auto-restart, dump capture, boot Safe Mode, clean GPU driver install, memory/PSU checks, then disk/partition diagnostics with backups.

Have a look in event viewer to see if that sheds any light on your problems.
