Solved Black screen crash & restarts, no BSOD

[Bowater]

your guess is as good as mine, i followed the guide and this is what happened.

I'm never going to try to update may bios with a cd again, my laptop won't play ball with it! So i did it by usb, this time used the the switch /nic which is something to do with networking. The reason i did that was because of the BSOD which pointed to NETIO.SYS. I'll let you know if it crashs again.

Spoke to soon, didn't solve the problem. I ran prime95 as soon as it booted and was working fine. The fan of the laptop was on full during the the test then as i stopped the test the fan stopped dead, then i had a black screen. Surely the fan should't just stop? In safemode the fan is always on all the time

Yes, you are correct. The fan should not just stop. Is the fan working again or does it still not work? If the fan isn't working, you will need to get that figured out before using the laptop again

yep the fan is working. Any ideas on what to do next?

Try running Prime95 again and see if the fan stops

I think i may of solved the problem. I'll let you know if i get a blackscreen. I changed the processor driver by going to update driver, and browse driver software and there was two compatible drivers for my intel p8700, "intel processor" and "processor". So i'm guessing the "intel processor" was installed so i installed the "processor" driver. I had to do this for both as it is a dual core, but now it seems stable. If this is the solution it's a simple one.

My laptop is now fine, no black screens or restarts. I can't believe it was the processor driver seeing as windows picks that driver. If you hadn't of identified that the driver was causing the bsod i would have never of thought it was that . Thank you.

How do i close or mark as solved?

I'm glad I could help. And good job on figuring that out. I will keep that in mind to have people try if they are having issues with the CPU.

It appears it has already been marked solved

Just an update. I had posted something in another forum about how switching to the "Processor" driver from the "Intel Processor" driver fixed your problem and this is what one of the members said

"Processor" has no sleep states or power management, the "Intel Processor" uses the intelppm driver and allows full power state management. If switching to a processor driver that doesn't allow sleep states "fixes" things, it's likely there's a hardware issue in one (or more) of the CPU cores or L1 caches at that point.

When you say "sleep states" what do you actually mean? Sleep and hibernate? because my laptop can sleep and hibernate, and I've no problems since changing the driver.

Yes. I assume that's what he meant. But if everything is working for you then just leave it be.
