This looks like an intermittent hardware fault rather than a software issue. Since has had temporary success after reseating parts and others asked about POST/beeps and full power cycles (, ), follow a short, staged isolation plan to find the failing part.

  • Power-drain and cold-start: unplug the PC, disconnect mains, press and hold the power button 10–15 seconds to discharge residual power, then reconnect and try a cold boot. This clears stuck states that can hide problems.
  • Minimal-boot: with power off, remove everything nonessential. Leave only motherboard, CPU, single known-good RAM stick (try each slot), GPU (or onboard video), PSU and monitor. Boot and watch for POST/beeps. Attach a small PC speaker if the case speaker is missing.
  • Memory test: if you get stable POST, run a bootable memory tester like MemTest86 from USB to rule out RAM errors.
  • Power supply check: intermittent video or hangs a few minutes in can be PSU instability. Test voltages with a multimeter or PSU tester, or swap in a known-good PSU. See a simple guide at .
  • Video and motherboard checks: try a different video card or use onboard video. Inspect the motherboard closely for bulging or leaking capacitors (common on older boards) — if caps look bad the board is unreliable (see Capacitor plague for background).

Do tests one change at a time and record what changes the behavior. If the machine runs for several minutes then fails, note whether fans spin up, voltages drop, or temperatures spike before the hang. If uncomfortable doing these checks, a local tech can bench-test with spare parts quickly; provide them with the test results to speed diagnosis.

after turning on your computer have you heard a beep?
coz if you haven't heard a single beep the problem would probably be with the memory card.
is there a power in your monitor? try to check power connection.

I've had something kind of like this happen to me before. When it doesn't shutdown/restart all the way. Try shutting down, letting it completely power down, and turning it back on.
