How can I stop Windows 7 64 bit from crashing every few hours?

By Muhammad Mahdi ·
For some time now I've been using WIn 7 64 bit version.
In the beginning it used to freeze after every 5-6hours but recently this happnes after around 2 hours of use.

The screen freezes whilst sound keeps playing. No BSOD.

I called Dell customer service and they replaced the motherboard and graphic card bu the problem still persists.

What can I do?

Have you tried:

Leaving it switched off? It won't crash then.

On a serious note, have you tried checking your drivers are up to date and are the 64bit versions? I noticed similar when I was on Windows 7, and it was my graphics driver

Updated drivers...

by Muhammad Mahdi In reply to How can I stop Windows 7 ...

Hehe, unfortunately I can't leave it off. I usually have it on around 20hrs a day.

I uninstalled the graphics driver, downloaded the latest one from ATI and tried those. Same problem. I undid and redid this but the same problem persists.

If you have it on that much

by Darryl~ Moderator In reply to How can I stop Windows 7 ...

it could be a heat issue (or maybe the HDD is getting too warm).

Are all the vents clear & fans running proper?

Fans clear

All the fans are clear, the laptop is placed on a table and for good measure Dell even changed the fans for me.

Video Card issue

by MikeBerg In reply to How can I stop Windows 7 ...

I had a similar issue with an HP Win 7 64bit machine that had 8 GB of memory and a high end PCI video card. If you have 8 GB's try reducing it to only 6 GB and see if that makes your system more stable.

The error message i got was:
**Hardware Malfunction
Call your hardware vendor for support
NMI: Parity check / Memory Parity Error
***The system has halted***

The Solution is:
Disabling the PCI SERR Generation feature in the BIOS.

This has no impact on system performance or the performance of the PCI graphics cards. Now you can add back any memory you took out and run the System as normal with 8 GB.

Reducing ram..

by Muhammad Mahdi In reply to How can I stop Windows 7 ...

I don't get any errors messages and all the memory tests that I ran passed.

With regards to reducing RAM, do you mean I should unplug one of them? Or is there a way to deactivate or reduce their speed via bios?

Reponse To Answer

by MikeBerg In reply to Reducing ram..

Unplug the power( as a best practice), then remove one of memory sticks. Plug the power back in and restart the computer.

See if that works better for you, if it does:
Disable the PCI SERR Generation feature in the BIOS.

Win 7 Crashes

by mperata In reply to How can I stop Windows 7 ...

I am with Darryl.

Make sure in your power settings you are allowing the HDDs to power down and the screen to turn off. You don't have to put the system to sleep or hibernate to do this.

Thanks for now

by Muhammad Mahdi In reply to How can I stop Windows 7 ...

I will try out enabling the the HDD to power down and see what happens tonight but the screen turn off was enabled.

I will inform you all of what happened. Thanks for the help

Windows 7 64 bit froze

by rick.manderville In reply to How can I stop Windows 7 ...

I have had my 64 bit Windows 7 OS freeze on me a couple of times. It was not the fault of the OS. I was using Adobe Flash 10.3 inside of Mozilla that wanted to place Local Shard Objects (LSOs) on the C drive durng a streaming download. Once I let it place them there for the duration of the streaming, there were no issues .. I deleted them afterwards.
