Acer Nitro AN517-55 extremely slow boot - BIOS POST time 67.6 seconds
Hey everyone, I've been dealing with a slow boot issue on my Acer Nitro AN517-55 (i9-12900H, 16GB RAM, Windows 11 Pro) and I can't figure out the cause.
The problem:
Boot takes about 1 minute 30 seconds to reach Windows login screen. The issue started suddenly one day with no changes made beforehand. Shutdown also has issues - screen goes black but fans spin at full speed and I have to force shutdown manually.
What I've already tried:
Checked startup apps in Task Manager (only Steam was High impact, disabled it)
SFC /scannow - no issues found
Windows Update - all up to date
RAM test (mdsched) - no errors
SSD health check via CrystalDiskInfo - 95% Good
Updated all drivers including NVIDIA audio
Reset BIOS to defaults, disabled PXE boot, POST delay set to 0
Checked for XMP/memory profiles in BIOS - nothing unusual
System Restore attempted - didn't help
Key finding:
Task Manager shows Last BIOS time: 67.6 seconds which is way above normal (should be 3-10 seconds). This means the problem is in POST/BIOS phase, before Windows even starts loading. BIOS version is Insyde Corp. V2.18 (7/11/2025).
Any ideas what could cause such a long BIOS POST time? Could it be a hardware defect?
