Hi @Hh233, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 

It sounds like your HP 89EB11 motherboard is failing POST (Power-On Self-Test) and shutting down. The short beep before shutting off usually indicates a hardware issue.

Try These Steps:

1️⃣ Power Cycle Your PC

• Unplug the power cord.
• Hold the power button for 30 seconds to drain residual power.
• Plug it back in and try turning it on.

2️⃣ Clear CMOS (Reset BIOS)

Since your motherboard doesn’t have a removable CMOS battery, try these methods:

Method 1: BIOS Reset Jumper

• Locate the CMOS jumper (CLR_CMOS or JBAT1) on your motherboard.
• Move the jumper from pins 1-2 to 2-3, wait 10 seconds, then move it back.
• If no jumper, short the two CMOS pins using a screwdriver for 10 seconds.

Method 2: Reseat RAM & GPU

• Remove and reinsert your RAM and graphics card.
• If you have multiple RAM sticks, try booting with one stick at a time.

3️⃣ Check Power Supply

• If the PC turns off instantly, it could be a PSU issue.
• Try a different power outlet or PSU if available.

4️⃣ Check CPU & Thermal Paste

• If you recently removed the cooler, reapply thermal paste and reseat the CPU properly.

I hope this helps. 

Take care and have a good day.
