Steps

Goal: Stop Windows from freezing.

  • Update graphics and chipset drivers.
  • Run Windows Memory Diagnostic.
  • Free disk space; run chkdsk; check for overheating.

Update drivers

Goal: Rule out driver-related freezes.

  • Device Manager → Display adapters → Update driver. Check manufacturer site for chipset.
  • Good: Drivers updated. Proceed to Run memory diagnostic.
  • Bad: Update drivers first.

Run memory diagnostic

Goal: Rule out failing RAM.

  • Search “Windows Memory Diagnostic” and run it. Restart when prompted.
  • Good: No errors; check disk and temps.
  • Bad: RAM failing—replace or call a pro.

When to get help

Call a pro if:

  • Memory diagnostic reports errors.
  • Drivers are updated and freezes continue.
  • The PC overheats after cleaning.

Verification

  • PC runs without freezing.
  • No lockups during normal use.
  • Task Manager and apps respond normally.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Drivers Update graphics and chipset drivers.
  2. Memory diagnostic Run Windows Memory Diagnostic; check for RAM errors.
  3. Disk and temps Free space; run chkdsk; check for overheating.
  4. Call a pro Memory errors, drivers updated but freezes continue, or hardware failure.

What to capture if you need help

Before calling support or posting for help, have these ready. It speeds everything up.

  • When freezes happen (boot, under load, random)
  • Memory Diagnostic results (errors or pass)
  • Free disk space on drive C
  • Steps already tried

Update drivers

Update graphics and chipset drivers. Restart. Retry. Run memory diagnostic if freezes continue.

Done

Does Memory Diagnostic report errors?

Failing RAM causes freezes.

Run Windows Memory Diagnostic. Good: no errors—check disk and temps. Bad: RAM failing—replace RAM or call pro.

Yes No

RAM failing

Memory Diagnostic found errors. Replace RAM or call a technician.

Done

Does drive C have enough free space?

Full disk can cause freezes.

Check free space. Run chkdsk. Check temps. Good: space and disk OK—uninstall recent software. Bad: free space; run chkdsk; call pro if persists.
