Other times, your PC may simply freeze during the POST with no error at all.

Maybe all you see is your system maker’s logo.

Troubleshoot the cause of theBIOSerror message you see on the monitor.

Disconnect any USB storage devices and remove any discs in anyoptical drives.

Clearing the BIOS memory on yourmotherboardwill reset the BIOS options to their factory default levels.

A misconfigured BIOS is a common cause of a computer locking up during the POST.

Test your power supply.

Just because your setup initially turns on doesn’t mean that thepower supplyis working.

The PSU is the cause of startup problems more than any other piece of hardware in a computer.

It very well could be the cause of your problems during the POST.

Replace your power supply immediately if your tests show a problem with it.

Reseateverything inside your system.

This will reestablish cables, cards, and other connections.

Reseat the CPU only if you think it may have come loose or might not have been properly installed.

If you’ve built your own PC or made hardware changes, triple check every hardware configuration.

Rebuild your PC from scratch if necessary.

Don’t assume that your motherboard supports certain hardware.

Check your motherboard’s manual to verify that the hardware you’ve purchased will work properly.

Check for causes of electrical shortsinside your rig.

Start your PC with essential hardware only.

If your system starts normally with only essential hardware installed, proceed to Step 10.

If it still isn’t displaying anything on your monitor, proceed to Step 11.

Since your system powered on with only the essential hardware installed, those parts must be working properly.

This means that one of the hardware components you removed is causing your gear to not turn on properly.

Replace the non-functioning hardware once you’ve identified it.

Test your gear’shardwareusing a Power On Self Test card.

Test after each hardware replacement to determine which component is faulty.

The average computer owner doesn’t have a set of working spare computer parts at home or work.

If you don’t either, my advice is to revisit Step 11.
