So i had my toshiba quosmio X870 14M mother board changed because

Resolved Question:

So i had my toshiba quosmio X870 14M mother board changed because it was black screening and wouldnt restore when i was playing games. Now 4 days later the same thing is happening but when i restart my laptop its just fine. A bit laggy on the start up but after 30 mins of gameplay the screen goes black but i can still hear the game on the background and i can still talk to my teammates via teamspeak. I dont know whats going on really. My laptop doesnt blow hot air out of it anymore so i guess its not overheat. My laptop is still runing but the screen is just black and when i connected an external monitor for one time and then pulled the cable of the external monitor off my laptop the screen on the laptop worked perfectly. Seriously i dont know whats going on.

Expert:  Charles A. Roberts replied 2 years ago.
I see and if you don't mind me asking have you tried restoring the machine taking it back time 2 months back to a date you know for a fact everything was working correctly to see if this is a software related problem?
Customer: replied 2 years ago.

they aready did that in toshiba but it didnt work

Expert:  Charles A. Roberts replied 2 years ago.
Ok so they did replace the motherboard did they ever check the CPU and memory by chance? Also has this machine ever been backed up and factory reset?
Customer: replied 2 years ago.

yes i assume they checked and it was restored but still it happens

Hi

I think the problem is in your graphics card.Run the following utility.Its going to diagnose your graphic card for any problem.
GPU Caps Viewer 1.22.0.

When its downloaded, go to GPU tab,at the end there is an option of OpenCL demos,click it ang select CL GPU-1M particles.Adjust width/height to full screen.Run some others if you like; just play with it.
I say its a must for enthusiasts but be careful with it,it may overclock your card ;)

Download another utility: GPU-Z.Then go to sensors tab.

Now run both these utilities TOGETHER.If you think there is any kind of lag or some reading which shouldn't be there then I believe your graphic card is giving you that black screen.You would need to get it fixed or get a replacement.

Cheers

it has no lag, both work perfectly but it says on the GPU-Z it says my GPU load is 99%

Expert:  Wiz of All replied 2 years ago.

99% GPU load when you're running the demo, right?
Moreover,have you installed more than one graphic card?

Go to any computer wizard who has complete knowledge of overclocking and ask him to CAREFULLY set your card speed (GPU memory clock and GPU core clock )to run at reference speeds.

If this doesn't help then I think its a problem with your PSU which is not giving your card/ or other components proper current.

The black screen usually occurs

1)when your PSU is not working properly and needs a replacement.

2)Graphic card is broken.

3)Could be anything else.

Customer: replied 2 years ago.

yes it is 99% when i run the demo and no i have one graphics card which is an nvidia geforce gtx 670m

Expert:  Wiz of All replied 2 years ago.

Hmmm..Do what I told you in my above post.If it still gives you the black sreen then the problem lies elsewhere. :(

from what u told me to download nothing lagged and this laptop had its mother board changed some days ago

Hi
Any update? :)
Customer: replied 2 years ago.

hello

no nothing

Expert:  Wiz of All replied 2 years ago.
Well, keep me updated. :)
Customer: replied 2 years ago.

probably with my 5 year no matter what guarantee i ll ask to replace it if i can :)

Expert:  Wiz of All replied 2 years ago.
Do your best to replace anything you could under the warranty.
Are you sure setting the clock speeds to reference speed didn't work?Something should have happened with your graphics after that.
Customer: replied 2 years ago.

I dont know if it is weird or something but you told me to download the GPU Z program and everytime i play a game if i open it up along with the game the game doesnt close down nor the pc shuts

Expert:  Wiz of All replied 2 years ago.
Not wierd.
If two programs are associated with one another then closing one of them might restrict its own end.
