Annoying recurrent graphical crash

Here is what happens every 10, 5, 30, 90 or 2 minutes:


I then need to send the comp into stand-by by closing the lid and revive it. This usually works, but sometimes (1 case in 7) not just screen crashes but entire comp and I have to hard-reset it.


Compaq V6065ea
Turion X2 2Ghz
GF Go6150
4GB Ram

It happens only in Windows 7 x64. It does not happen in XP x64 or Linux x64.
I tried 4 different nvidia drivers (modded and not, newest and from 2008) and drivers form Windows Update - made no difference.
I reinstalled system on freshly formated drive trice, with different 7 releases.
It usually happens when the CPU is barely used (but then again, it's like this most of the time).

If I can't solve it, I will have to go back to XP 64 where I have to sacrifice 1GB of ram to enable hibernation and most modern antivirus programs do not work.

 

up.
come on

 

which video drivers have you tried.
after updates to the latest few i get bsod so revert back to 186.81 which have never caused a problem.
if youve tried them then i have no idea

 

Uninstall the nvidia driver and see if it works fine. It might be something else.

 

I tried
256
195
190 (modded)
180

Looks like I am going back soon to xp64.

As I said, it also ocured with windows update drivers so I doubt graphic drivers have any influence on it.

 

This may be similar to the issue native to some Acer laptops (incl. my own).
The image has a tendency of turning grey for no apparent reason at random intervals (although it was relatively frequent at first, I found a way to prevent it from happening for at least a month).

The trick in my case was to remove the plastic casing where the power button is and tug the gpu cable a bit.
After that I opened/closed the lid again and the image stabilized (no problems occurred for about a month ... after which it started happening again).

It's not a big issue (in Acer's that is) because the gpu cable connections apparently get a bit loose due to continuous opening/closing of the lid.

I'm not sure if that's the case with your laptop, but it certainly doesn't hurt to try.

 

Thanks but I doubt it is hardware-related since the problem is restricted to Windows 7.

I am more inclined to thing it has something to do with CPU when it goes into low-freq mode. I am using RMClock to undervolt it and what I observed is that when it happens at at 800Mhz @ 0.675V, I am able to recover it with "Sleep" function but at 800Mhz @ 0.662V it usually doesn't work.

The thing it, it also happened when I was not using RMClock and let windows manage the CPU by itself at stock voltages.

 

Some update.

I checked and the problem OCCURS in:

Windows 7 x64
Windows 2008 R2 x64
Windows 2008 x64 (and so I guess in Vista as well)
Windows XP x32


Problem DOES NOT occur in:

XP x64
Ubuntu 64bit
Arch Linux 64bit


Any ideas?

 

I think your graphics card is starting to show signs of near failure. Have you heard about nvidia g84/g86 problem? Maybe your card is affected.

 

Yeah, I think so. It is this damn HP unique design of implementing stove function into their laptops.

 

It's not maybe but definitely. 6000-series integrated, 7/8x00 -series discrete cards, as well chipsets of that era AND also the desktop variants are all affected by same issues.

It's just matter of luck how fast the laptop dies but quite often it can be resurrected with a little work.

 

Here is something that flabbergasted me: I replaced the Motherboard with another one and... THE PROBLEM REMAINS! How is it even possible?!?
