BSOD caused by nvidia drivers (i think)

Hi peoples,

I have had help on here before any help greatly appreciated!!

My probem is my hp pavillion dv2700 randomly crashes to BSOD or sometimes a black screen where i have to force shutdown or a black screen with pixels. It can run for hours with no problems or sometimes 10 minutes. More often than not its playing a game or watching a movie from hard drive but sometimes just browsing on firefox.

To date I have ran memtest overnight with no errors

Defragged hard drive

Ran system check on start up (which will stick on last step at usually 28% or so if i remember correctly)

updated virus programs (AVG and Spybot, Malware Bytes) all report no problems

updated drivers : chipset and graphics by unistalling then rebooting, using driver cleaner pro to remove any traces in safe mode and installing new drivers (again in safe mode)

I have replaced Nvidia drivers with the latest ones and archived ones to no avail, also tried omega drivers....same result.

I downloaded blue screen review to get dump files from latest BSOD and they point to nvlddmkn.sys as the culprit (nvidia) or sometimes ntkrnlpa.exe (not sure what that is )

My specs are:

windows vista home premium service pack 1 32 bit
Geforce 8400m GS current driver (latest from nvidia) 8.17.12.6099
Intel core 2 duo t9300 @2.50ghz
4GB ram

I have attached my last two BSOD reports if this helps

Thanks in advance.

 

Here is my everest report on my machine specs also :

 

Hi thanks for the reply,

I ran speed fan which reads my GPU temp at 74C / HD 54C / Temp1 66c / Temp2 66C / core0 57C / core1 60C

I take it these are hot. I did think the laptop was hot before and have hoovered the dust from the vents (there wasnt much there) I was going to go into the fan itself but my laptop is very hard to fet to the fan and video card. the whole front has to come of and the screen taking of etc.

If these are considered hot however i will get it checked out. I can hear and feel the fan burring away as norm.

 

Hmmm i lifted my laptop and blew really hard on my vents and alacazam my temps are dropping rapidly on speed fan. I am abroad working just now and cant get into my laptop but hopefully this has dislodged dust and solved the problem. I will update any further probs.

Current hd temp is 58 (still hot i imagine) and dropping slightly
core0 39c
core1 44c
temp1 49c
temp2 49c

David on a footnote can you install vista service pack 3 after 1 or do i need to install 2 first?

Many thanks.

 

Has definatley been the problem as I have had no crashes since temps have dropped. I will get SP2 when home, Thanks a lot m8.

 

In regards to vista SP2, It has been my experience that If this machine DOES NOT already have SP1 installed he must have That installed FIRST. Otherwise SP2 will not install properly.


Assuming this is a 32-Bit system --

Service Pack 1

Vista Service Pack 2
