Spent 2 hours chasing a phantom boot loop, turned out to be a loose RAM stick with a hair on it
So I had this HP ProDesk that kept crashing right after the Windows logo, same exact spot every time. I tried swapping the power supply, reinstalling the drive, even flashed the BIOS twice. Then I pulled the RAM out and noticed a single long blonde hair stuck between one stick and the slot. Cleaned it off, reseated everything, and the machine has been running solid for 3 days now. Anyone else ever find something weird like dust or debris causing intermittent issues?
