Hi @Anshulrawal,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I understand you’re frustrated with your HP Pavilion Gaming 15 (ec0101ax) laptop after replacing major components and now facing freezing issues possibly related to BIOS or RAM. Let’s go through a few steps to help diagnose what could be causing this.

a. Check System Health & Temperature

Download and run a tool like HWMonitor or HWiNFO to check CPU, GPU, and motherboard temperatures during idle and under load.

If temperatures exceed ~90 °C for the CPU or GPU, it could cause freezes or instability.

Also, check for thermal throttling or CPU clock locked at low frequency — these can be caused by BIOS or power delivery issues.

b. Run Memory & Storage Diagnostics

Press Windows + R, type mdsched.exe, and run the Windows Memory Diagnostic.

Also, in BIOS or UEFI, run HP PC Hardware Diagnostics UEFI (press Esc → F2) to test the memory modules and SSD.

If one of the RAM sticks fails the test, reseat or replace it and test again.

Make sure the RAM you’re using is compatible (speed and voltage) — mismatched modules can cause instability.

c. Update Drivers and BIOS (Carefully)

Visit the official support page for your laptop model: the “Software & Drivers” section. HP Support

Install all latest chipset, graphics, and storage drivers first.

For BIOS: note that rollback may not be supported. Several community posts for this model state that once BIOS version F.20 is installed, older versions may not be downloadable or installable. HP Community+1

If you suspect the current BIOS version is problematic, ensure your system is running on AC power, backup all data, and check whether HP has released a BIOS update addressing your issue.

d. Reset BIOS to Defaults and Clear CMOS

Shut down the laptop, unplug the AC adapter, and if possible disconnect the internal battery.

Hold down the power button for ~15 seconds to discharge residual power.

Reconnect power and press the F10 key at startup to enter BIOS.

Select Restore Defaults, save changes, and exit.

This can clear corrupted settings which may cause random freezes.

I hope this helps.
