Can't boot my Pc after checking the box under Maximum memory

Restoring registry hives from backup may resolve your PC boot problem.

I mean the motherboard logo wont show up

Does the PC power on?

Does the PC power switch light is on?

Does the PC fans turning?

If the computer passes the POST, the computer may give a single beep (some computers may beep twice) as it starts and continue to boot. However, if the computer fails the POST, the computer will either not beep or generate a beep code that tells the user the source of the problem. Can you tell us if the computer generates beep code and how many they are?

I dont hear a beep but the pc fans spin power lights on and my pc is on

Can you please reset BIOS settings by taking out CMOS battery.

How to Reset Your BIOS

Just did and nothing happens

Reset the RAM modules by reconnecting the RAM modules.
Blow off any loose dust or debris from the RAM using canned air. Hold the module by its edges.
Clean the contacts using a soft cloth that does not leave fibers behind, such as a lens cleaning cloth slightly moistened with rubbing alcohol.

Ill try that tomorrow thx for the answer

But it is not a guarantee fix

We don't know why your computer is not booting but it does look like its hardware problem to find out which we need to test all the computer components one at time.

You can also try below suggestions.

Reseat the memory to see if any difference. If no change-try with one stick of memory, then the other to determine which one is bad, or if both need replacing.




Please try a hard reset and see if it works.

1. Power off your laptop
2. Remove the a/c adapter, battery and everything that is attached to your laptop.
3. Hold the 'POWER 'button down on your laptop for about 15 seconds.
4. Plug in the a/c power supply (without battery) and power on.
