Resolved W7 Bsod Crash The Restart Ok .. Nv Driver ?

hi guys ...@PeteC ...
you cud be onto something about the kernel ,,, but ,am now not able to boot pc at all ...
no display , no POST , no DOS scrolling boot text , ...
can't invoke F12 to multiboot into XP on my other internal hd ... { not a good sign }
weird ,and cud be a list of reasons why ,,, will have to begin to check them out tomorrow ...
peculiar thing is when I first powered on this am , it actually did a normal non-BDOS bootup ...
I then switched off to repeat the good start ,and "nothing" ...
I will begin with removing replacing the cables ,,
if still no-go then will take off the top and side panels and see whether power su is servicing pc , what lights up etc , and ( I hope ) see lots of dust , will clean , and remove vid card to clean ...etc...
next will depend on what is working / not working ...

@ Evan Omo ...
thanks , lots of interesting possibilities , but ,as above , unable atm to check ...

fortunately I have a handy old HP laptop ... and can access email via Webmail with my ISP ...

will see how we go in he morning ...

 

Inspect your motherboard and graphics card for leaking/bulging capacitors

 

hi Pete C ,,

well , a full day today on this one ...

most of the morning I spent on revising what I iknow / don't know about W7....
Win 7 Bible , other mags and tips etc... visited geeks , howto's , and so on .. NV sites for FAQ's ,... the whole deal ..
then began the real stuff.. checked ,tightened , removed , replaced ,cables
tested monitor as best I could .. looked into hooking it up as a multiple on my old laptop , but didn't have right cabling ,,
checked all other cables into pc ,and the source power plugs ...
so ,then removed sides and top of atx box to do some heavy sleuthing ...saw some dust inside , blew some away , .. next I switched it on to see what was working inside and what not ...
PC STARTED !!!! ..
up came boot screen , then starting windows ... then a crash back to the boot screen , then "Windows did not close properly ... , then black white screen with Start options m selected Normal ,,,then Starting Windows , and away we go !!
NOTE ...was no BSOD !!! ???

I repeated this procedure a number of times over the period of 2 hours ..
tried some of the other suggestions during that time ... no change to above ritual ...
tomorrow I will take the box outside and give it a huge clean inside ,and also the vents which are very clogged ...
will then see how it goes ...
I don't know why I no longer see the BSOD ... only difference is pc I moved a little to get access to inside , ,and the sides are off ,which wud make it cooler ,altho all the fans and psu fan are working ... but , was dust blockage for airflow in ...
temps inside , in deg F , have been steady all night , cpu 96F , cores 100F , system 85F , GeForce vidcard 109F ... which I think are ok ?

also don't know what/why is "Not close properly " ...

I looked at the .dmp files in Minidump ... each mention the NV driver ...

oh ,btw , very important ... I can now F12 to select to boot in XP , which ,as before , boots up no probs ... ( so vid card must be seating ok } ..

I wonder if I am now just chasing shadows ... ??

hmmm... would I likely see much difference between the NV driver and the M$ default VGA ? I do some Photoshop fixing and editing , and some video edit ,convert format etc stuff... watch some sport ...
occasionally watch a movie , wud frame rates suffer ?
appreciate your thoughts ..
thanks ..

 

hi Pete C ...
excuse delay since my previous post ...
done a lot in the interim ...
in summary , rejigged ,reseated vidcard ,cleaned surface dust ( lots !! ) inside and on vents ,fan blades etc., checked secured cable connections ...
no improve !
tried Clean Boot , followed all steps , reboot etc.
then rebooted to reset to Normal boot...
rebooted ...
had a pc which was working ,,,, but had a black screen ... no BSOD or boot messages , just a black screen ... lights on pc .fans swirling etc ..
so switched off , cleaned some more inside , vigorously rattled vidcard to reseat, checked cables etc ...
cut a long story short , after hours ( ! ) of trying , I went to move monitor for some easier access , and touched the power cable connected to rear of monitor ... {{ gasp }} lit up and displayed screen of desktop !!
switched off , restarted , all ok ,no BSOD ,no messages ..
did it 5 times ... all ok ...
also note ,bootup from power on to welcome = only 80 seconds..
ran pc for 2 days ... on-off-on etc ... all ok ...
checked some apps ... burned a movie dvd ( TSVideo) , only 3 minutes ... not been that quick for a long time..
so ...{ putting monitor matter to one side } ? clean boot most probably helped , not sure if/how reseating card helped , and the cleaning ...
because I had thought the black screen monitor was part of the total failures , I did /tried a number of things without being able to switch off/ reboot and view the results onscreen , I can't pinpoint the precise " cure ", or sequence which worked ..
is so frustrating ,after the weeks of controlled trial and error ,all documented step-by-step ,(huge paper file ) ...
anyway , I have run pc every day for a week now ,so as to be sure ... before posting " SUCCESS " here...
I have been inside and out of pc's since DOS 3.0 , with some mindbending headaches along the way...
each time I have been able to overcome them ...
but , most certainly, I would not have resolved this one without all your help ...
will tag this Solved in a few days ...
many thanks to you Pete C , and Evan Omo , Tony T , and other contributors ...
