Najeeb :

Hello and welcome to JustAnswer!

Najeeb :

Have you tried hard-reset by removing the battery, disconnecting the power cord and then pressing and holding the power button for 30 seconds before releasing and then trying powering it up?

Customer:

No. Do I replug it in and then restart?

Najeeb :

Yes.

Customer:

Including the battery installed, right? IF that does nothing, what should I try next?

Najeeb :

Is it possible for you try this as I standby?

Customer:

No. The computer is at home, as I am take work break at lunch trying to trouble shoot.

Najeeb :

You can first try powering it up with battery removed and only power cord connected and see what happens.

Najeeb :

If it works OK, plug in battery and power it up again and see if the problem is still there.

Customer:

OK. If this does not work is it smarter to start with a new computer versus replaying motherboard?

Najeeb :

Moreover, it is worth checking if your laptop is still under warranty or not.

Customer:

Not under warentee. expired 5 months ago.

Najeeb :

The next step is to get the RAM ICs re-installed properly.

Najeeb :

What is the operating system on your computer?

Najeeb :

If it is Windows, it is also worth checking if the behavior remains in safe mode

Najeeb :

i.e. before doing anything else.

Customer:

It was the one that came out after Vista. How do I get to safe mode. I forget.

Najeeb :

To get into safe mode, restart computer and as you get the first screen, start pressing F8 repeatedly till you get the boot menu from where you can select Safe mode, safe mode with networking etc.

Najeeb :

Trying each mode one by one should help diagnose the problem.

Najeeb :

ie.e safe mode, safe mode with networking, safe mode with command prompt.

Customer:

OK. here is my plan. 1) try safe modes one by one 2) remove battery and plug and hold start up 30 seconds and try again, 3) RAM IC's.

Najeeb :

Great. A sub-plan to 1) is to get your computer scanned with anti-malware if computer works fine in any of the safe modes.

Najeeb :

Here is the link to the anti-malware whose free version will suffice.

Customer:

OK. Thanks. Have a great day. Logging off now.

Najeeb :

Have a nice day. Let me know in case you still have problem. Take care.
