My PC consistently freezes after 3 to 4 hours of active use.
1. The Freeze
The screen completely freezes on whatever program or game was open.
Peripherals lose power: The LED light on my mouse turns completely off.
SSD activity stops: The red blinking storage LED on the PC case stops flickering.
Fans keep spinning: All internal cooling fans stay on.
2. Reboot & BSOD Behavior
Holding the power button to force a shutdown and restart takes an unusually long time.
When it turns back on, the mouse light stays off this is always my warning sign that it won't boot properly.
It then crashes into a Blue Screen of Death (BSOD) showing the error in [Pic 1].
After the BSOD, it often bypasses Windows entirely and boots straight into the BIOS (Aptio Setup Utility) shown in [Pic 2].
3. The Only Temporary Workaround
If I turn off the PC and leave it unplugged/cooling down for a while, it boots fine and works normally until another 3–4 hours of use pass, and the exact same thing happens again.
Repair Shop Visits (3 Times)
1st Visit: Tech saw the Aptio BIOS screen and just reinstalled Windows. (Didn't fix it).
2nd Visit: Tech claimed there were "scratches on the RAM" and added padding/cushioning. The PC worked at the shop because it hadn't been running
long enough. (Didn't fix it).
3rd Visit: Tech left the PC running idle for a full day without running any stress tests or games. He claimed nothing was wrong.
Now that I have to visit him again since my i have insurance there is he trying to avoid any heavy problems that may cause the problem to be solved.
Any help would be appreciated
