i recently upgraded my graphics card from 8600gt to 250gts.after installing the card n its drivers i am getting bsod right before the welcome screen of windows 7.i have already tried formating my windows but the result is the same.however when i remove all nvidia drivers n restart the problem does occurs.


plz help me........................

-did you connect a 6-pins power-connector ? = is necessary
if yes ,
-if you have 2 pci-e slots try the other one

bsod usually not come from windows
use driver from Nvidia site , not from the box

yes i have connected the power supply to gts250 n using the latest driver from nvidia 260.99.

using 500w coolant master power supply.

500 is not much

the link u provide is not working as in i cant select my cpu n graphics card.i m ready to tell u all the inf u need.here r specs of my system


2.93 c2d
4gb ram
win7 32bit
1 dvdrw
8 usb ports
intel g31/pr motherboard
gts 250 nvidia card 1gb
thats all i can think of. if any more info u require just tell me in this topic n i will give u.

then you are around minimum
if the card is not damaged , fully seated and powerplug is connected it should work normal

-what is the error code on bsod ?
-with old card re-installed , is the problem gone ? [ to make sure its the card and nothing else ]

0x16 bug check code
it says somthing about reset driver n file name is nvlddmkm.sys

yes the problem seems to have gone when i use my old 8600gt 512 mb.

try ;
un-install the driver [ Control Panel\All Control Panel Items\Programs and Features ]
remove any nvidia-folder from C:drive you can find
go to ; windows/system32/drivers and rename nvlddmkm.sys to
nvlddmkm.sys.old.

reboot

switch off an insert 250 card
now reboot
install driver again

edit
these new drivers contain stuff that dont belong there
use custom install and select graphic driver and physics only

i have used both the driver sweeper n the driver cleaner.net but i will still give ur method a try n will let u know the results.


will also attach the .dmp file.if u can analyze n tell me what is the problem it would greatly help me or you to know whether there is a driver issue or not.

just make sure you download the correct driver

well i did what u told me but i keep getting the bsod.

here is the dmp file

give the text version
i cannot view .dmp

how can i do that plz explain.

highlight text by dragging mouse over it
right-click
select , copy

paste into a new text file , witch you can insert as attachment
or paste in directly in reply , preferably with quote marks

how should i do that coz i dont have any dmp viewer

i looked it up
its memory dump we dont need that

in the bsod is an error code
what is it ?
sometimes it can be useful

it looks like 0x000000000number

its something like 0.................x16

mayby somehing with MoBo

go to device-manager and see if there is a cross or a question-mark
download latest drivers for it , either from Microsoft or from Intel [ if that is the manufacturer ]

[Only registered and activated users can see links]

no there is no cross or question mark and i have the latest drivers for it.i downloaded from nvidia site

then i dont know anymore
i still say , you need a stronger PSU , even if its not the cause
this card uses a lot more power then your previous card

i gave new calculator above
try and see the different

Why don't you try an application called "WhoCrashed" from here

It will analyse your PC and give you details about which driver caused the BSOD

:goodluck:
