Computer Won't Start

HP Recommended
Envy Desktop 750-120
Microsoft Windows 10 (64-bit)

I tried to upgrade my memory by buying an 8g ram chip but when I installed it it didn't work then when I replaced the original chips now my computer doesn't send a signal to my monitor and the power button just blinks.  Is there any way to fix this or should I start looking for a new pc?

Greetings Diehl,

Welcome back to the forum.

I am not an HP employee.

 

Reseat the factory memory modules.

 

You may have damaged one or more memory slots or the factory memory is damaged.

 

Try one stick of factory RAM in each memory slot. Boot the PC each time to see if it will POST.

 

Visually inspect all other connections to the MB. You may have dislodged a different connector on the MB.

 

Also try shutting down. Disconnect the PC from AC power. Hold the power switch down for about 20 seconds. Reconnect to AC power.

 

Regards

Thank you for your advice, unfortunately nothing worked.  I still get no signal to my monitor and the power button keeps flashing and beeping.

Hi Diehl,

 

You're very welcome.

 

You could be the victim of collateral ESD damage.

 

Disconnect the PC from AC power. Depress the power switch for a bit of time to drain residual power from the motherboard. Remove the side panel.

 

Pull the motherboard CR2032 battery which is located near the SATA ports. Let the PC sit for about 10 minutes. See if this helps.

 

It would appear you have caused some accidental damage if the PC was working fine before you attempted the memory upgrade.

 

If all MB connections and internal device connections are secure then either the factory memory or the memory slots are damaged.

 

Carefully check everything again.

 

You will have to have the PC looked at by HP or a local PC technician.

 

This is as far as I can go to help with your problem.

 

Regards
