    I posted this on windows forum but as no one has answered more the merrier I guess

    My computer is loading up to the point the windows logo starts to flash before changing over to the chose user screen and then just frezing. *I have tried runing the boot fix and it came up as unable to repair, i have tried restoring to most recent restore point and got the same problem. *Has no issue booting into safe mode.

    I thought I had fixed it, deleted display drivers and it starts perfectly

    Then tried installing new NVIDIA driver and it got as far as black screen with mouse pointer and then screen turned off because no signal (no chime from speakers either)

    Tried NVIDIA Beta drivers and same problem

    TQried letting the computer auto install drivers and restarted and got it working fine, played Diablo 3 for 3 hours, left computer sitting there in character screen (so not doing anything) came back and it was switched off

    Turned back on and freezing at windows logo problem back, tried installing beta drivers and got the same thing

    Boots fine into safe mode
    Boots fine when drivers deleted

    I have tried every NVIDIA driver I have from march and it's Beta (which is what I was running) to the current drivers and today

    I would have posted this to NVIDA but there forums are down
    It worked perfectly till yesterday
    I'm running a GTX 460

    Sounds to me Asguard, as if when you left the computer for a duration it went into sleep/hibernate mode. At this point the information that housed in the RAM is usually written to the hard-drive so on waking the RAM can be repopulated. This can cause faults.

    For instance if you have faulty RAM it will develop a fault if it's read from then written back to the RAM, since it potentially misreads it coming off and also back on. RAM is notibly of important in graphics too, since it's used to cache all the textures that the cards tend to use. While GFX cards have potentially onboard caches nowadays (and a myriad of pipelines for generating high spec non-laggy graphics), they still don't respond too well if the memory addresses (RAM again) they have been allocated happen to have problems.

    Now before you think "Great now I've got to get some new RAM", you could try at least looking in your BIOS settings. Sometimes an onboards CMOS loses it's charge a little and the next thing you know, it's attempting to run at Factory defaults, which is great unless it's been set to use some other settings.

    I'm pretty sure it's going to be a RAM problem though. If I was twiddling around with it, I'd probably write down and Memory Address ranges that the card sets as default and perhaps attempt to use different addresses if possible. If you get your system back up and running, set it to a lower screen resolution setting and then checkdisk/defrag the drive (Setting it lower means it won't use so much RAM, which means while it's defragging it will less likely cause it to blank screen/signal drop on you.)

    Once you've done a defrag you can try turning your resolution back up. (The idea is that you are just reducing the potential of faults while trying to get the system stable)

    Asguard, could possibly be numerous things causing your problem. Hard to really narrow it down without knowing the full mechanical spec's of your machine.
    I personally only upgrade drivers when absolutely needed - especially Video drivers, because sometimes the updates only address problems with certain games or hardware combinations - kind of like the " if it ain't broke, don't fix it" school of thought.
    Believe the reason it boots fine in "safe mode" is that it uses basic VGA drivers.
    First thing I would try is to make sure that all the motherboard/chipset drivers were current (up to date) and then uninstall ALL nvidia drivers, instructions here - "" (copy/paste all inside quotation marks to browser)
    Then I would uninstall any/all nvidia programs/utilities through windows control panel.
    After restart, I would then try the new driver package.
    If that does not correct problem - just use most recent drivers that worked! Just remember to completely uninstall the problematic drivers (by booting into safe mode) before reinstalling previous working drivers!
    Mind you, these are only basic ideas because as stated before, I do not know your full hardware specifics or whether you are over over-clocking (CPU/GPU)? Does you motherboard include onboard graphics- does your CPU have on die graphics? Is your CPU AMD or Intel? How many and what programs do you have running at start-up?
    Personally, I have never owned an nvidia 460, but have serviced quite a few PC's with that card. Just like all video cards, driver mismatch/interactions can cause any number of problems. I have seen video driver updates put more of a load on power supplies and cause problems when the PSU was borderline powerful enough in the first place.
    Depending on how much trouble you want to go through to correct problem ( or amount of money you want to throw at it!), would probably be wiser to just use the drivers that worked previously, if they were working O.K.
    Hope I was some help, and good luck!
    BTW, do not let my user name dissuade you - most operating systems are designed so that even people as dumb as myself can use them. Heck I've even heard tell (hearsay evidence, mind you) that computers are used by Lawyers, Policemen, Car Salesmen, Politicians, Churches, Corporations, CEO's, Governments, Sheople...

    Asguard. Did you ever get nvidia 460 problem figured out? Like I said earlier, could be any number of things. Just interested in if/how you were able to solve conundrum?
  8. Asguard Kiss my dark side Valued Senior Member

    I think I solved it yesterday but I'm still stress testing it. Went to computer store and told the guy there what I had done and what was wrong and he said 9/10 times problem I'm discribing will be a busted video card. Replaced card with new 560 and it seems to be working now, no crashes (just one scary time when monitor turned off but that turned out to be a lose cable from when I put computer back together

    Usually your mobo gives you some beep codes. My graphics card beep code is one long and two short, I think (ASUS?). Another way to test your graphics card is to set the resolution to be low, which I think you can get to in safe mode, and reboot. That worked for me once.
