Tried that fix but got stuck at part 3 stage 2 expand.exe nvlddmkm.sy_ nvlddmkm.sys" and then press Enter, I did this and cmd.exe says "no destination specified for: nvlddmkm.sy_ nvlddmkm.sys

Been going through those google results and it seems this nvlddmkm issue can be caused by pretty much anything : /
 
have you tried older gpu drivers? try underclocking your mem on your gpu's by 20mhz, some say this works, they also say raising pci freq helps

Yeah tried several previous drivers including the drivers that came with the cards.
Not tried underclocking the VRAM yet, will give that a shot tomorrow.

I'm not willing to raise my PCI-E frequency above 101Mhz, don't wanna corrupt data or damage my sata devices.
 
Installed my new Core i7 960 and thought I'd do a fresh install of W7 again, got loads of restarts (that aren't supposed to happen) whilst installing W7, so new CPU hasn't solved the issue, So I've replaced every part, and it can't be a software/driver issue if it happens on a completely formatted drive.

So really confused and very annoyed now, parts will be going on a well known auction site and I'll probably just have to buy a pre-built PC which I'm not to happy about as I enjoy building PC's.

Thanks for all your help anyway guys.
 
Its a shame that you have decided to give up and sell your stuff. I am baffled as to what it can be.

Has anyone mentioned in a previous thread your install disc. I'm sure they have. Have you tried installing a different OS i.e xp or vista?

There has to be a logical solution to this problem
 
Are you sure its not the cpu overheating? bad contact with the waterblock, or older block(or newer one) clogged with bits of gunk, pump working at incorrect voltage, something along those lines.

Did you try without the fan controller, its not hugely likely but its possible for a fan to cause some issues aswell so could try turning half off, then the other half.

Some setting you've overclocked, cpu overheat protection set too low, or ran rpm safety which is auto shutting down without detecting cpu fan, that kind of thing.


Nvidia driver crash, despite the love of bashing Nvidia, is likely down to an unstable system vs bad driver.

They do make the odd bad unstable driver, everyone does, but because of the usage, crashing more in 3d, and also just because the gpu is one of the biggest and most complex drivers, its the most prone to failing in an unstable system.

99% of AMD "driver has recovered" or the total crash version, and Nvidia driver crashes are down to a system thats just not stable. Frequently caused on this forum by someone having a X specced rig which is stable at whatever overclock, then they go from a 285gtx to a 480gtx, and suddenly its Nvidia driver crashes all over and they suspect bad cards/drivers, when normally its just that extra power means that for example 3.7Ghz overclock, is now only stable at 3.65Ghz, because the CPU is being pushed more, the gpu is pushing hard, the psu is being pushed harder and is a little hotter and the rails have gone down marginally.

I'd try again with a minimal system, make sure all hardware monitoring type things are disabled in bios, check the bios temp readings, make sure the cpu isn't getting too hot. Increase voltage, marginally, on the cpu, memory up 0.1v over whatever its default is, not bios default. Just the hdd, as few fans as possible, off mobo headers or molex's, disconnect the fan controller, one gpu, check with the PSU which rails everything is on, keep both pci-e connectors for one gpu on the same rail, also have the memory at 2t rather than 1t.


You could always, depending on whats around you, take the computer in to a shop ask them to have a look for you.

CPU block is very clean, cleaned it out a few days ago (had some cat hairs in there, ewww!!!) Temps are good with 50C under Prime95 (9 hours), Thermal limit in the BIOS is set to 90C.

PSU uses a single 12V rail like my previous HX850

Already tried without the fan controller (and other non-essentials) but got the same issue.


The last few days have been the worst, sometimes I can't even get into windows, most of the time I can get into safe mode but it has restarted on me in safe mode. Haven't even attempted to play anything on this install of windows (no games or benchmarks installed), getting random restarts all the time.

Took my cards to a friends house today and one of them didn't even diplay anything at all and the other one worked flawlessly running unigene for an hour. This is very different to what happens with my PC as with either card my PC will restart so don't know what to make of it all really.

Was looking at PC worlds PC's the other day and felt sick at how much they overcharge, but its a working PC.
 
Well I would say graphics cards don't have enough voltage for their factory overclock

Also what sort of tight duck mate let's u only test for 10 mins

Check your socket out let voltage are u using a multiple plug exstender?

im thinking its something to do with voltages too, try get a realtime voltage check program, if you cant get into windows go into your bios and check whatever voltages you can check there ie 5.5v,12v 3.3v etc, i remember getting freezes and corrupt graphics with a low 3.3v output, was outputting at 2.9-3.1 iirc


also i dont know if you have already tried but try flashing your mobo to every older bios revision stopping and testing after each flash of course

Tried both cards at GTX570 stock clocks, still no joy.

I've also tried with surge protector (multiple sockets) and just plugging the PC straight into the mains.
