Repeated Boot/Startup Freezes

[simonholbrook]

Hi

 

Over the last year my PC has been going through repeated issues when booting or shortly after. It doesn't give any errors or blue screens it just stops until I do a hard power off then when re-booting it will either do it again , boot up with no issues or occasionally it will take me through the advanced boot up/troubleshooting steps.

 

I'm not aware of any hardware changes that may be causing this so I'm a little stumped. I have managed to generate a boot log but I'm not able to work out what the issues are. I've attached it in case it's useful to anyone.

 

Thanks

Hi and welcome

 

Your Bootlog shows normal boot except for - NDProxy.sys and dxgkrnl.sys

These are both System Files located in the System32 Drivers folder.

 

Try this:

If you can get your machine to boot up -

Search box [ bottom left of screen] > type in > cmd

"Command Prompt" will show left of screen.

Right click on this > select "Run as Administrator"

 

At the black Command Prompt screen type - DISM.exe /Online /Cleanup-image /Restorehealth

now hit Enter.

[there is a gap before the / in each case ]

This may take 5 - 10 minutes.

 

After this has run please type the following : sfc /scannow

hit Enter.

This process checks and repairs corrupt system files.

It will take some time to run so please be patient and DO NOT close the Command Prompt.

 

==========================

 

If your machine will not boot up BUT you are taken to Advanced Boot Up options ....

Command Prompt should be available from there.

Thanks for the reply. I was able to complete the first step but the second keeps failing

Hi

Faulty RAM could be the cause of BOTH the startup and the sfc /scannow problem.

 

Try this:

Unplug PC at the wall.

 

Locate the RAM modules and if there are two remove one module.

Try booting up with just one module in place.

 

If you get the same start-up problem then shut down > unplug at the wall > swap the RAM modules over

Try booting up again.

Thank you for this I will try when I can spend some time on it. I was on my PC briefly today and it froze again after being on for about 15 minutes, this time I got a blue screen with the error "driver overran stack buffer". Not sure if that helps or not.

 

Thanks

Also I have 4 sticks. How many should I remove at a time to narrow this down?

[KenB]

Hi

 

Remove two.

Some motherboards have matched pairs.

If your RAM slots are colour coded take two out from the same colour.

If the slots are coded A1 - A2 etc leave A1 and A2 in place take out the other two RAM modules.

 

If swapping over - use the same two slots.

 

If you have any problems let me know the Make and Model Number of the motherboard.

This will be written in large font on the board.

Thanks this looks to have fixed the problem. I haven't tested the set I pulled out first as they seem to be the faulty pair but of it turns out one of them works can I have 3 sticks in or do they have to be in multiples of two?

Hi

Glad that we seem to have located your problem.

I would be inclined to leave the two RAM modules in place for a while and see if the problem really is identified.

 

As to running 3 modules [ instead of just 2 ]

It depends on the motherboard.

As I said earlier - some m-boards need matched pairs.

 

If you can let me have the Make and model number of the Motherboard I may be able to find out for you.

 

Your system will run slower on just 2 RAM modules

Depending on what you are doing you may not even notice.

 

What is the value of the RAM modules that you have taken out?

Do you know if your system is 32 or 64 bit ?
