[Ayman IBreak]

this is an old pc
core 2 duo e4500 2.2 GHz
2 gb ddr2 ram
320 HDD
gt9400
i just want it to run
no upgrades i know it's almost dead for anything
but some times i open some games on low
it was always working
until i turned it up once and bsod came up saying nvlddmkm.sys crashed
i went into safe mode and deleted all the drivers (newest)
1 installed the beta driver
2 deleted driver and installed an old one
changed the PSU
i have 500 watt no brand
tried every thing any help would be awsome

Does it have onboard video? If so try running on that. That bsod references nvidia driver as the cause.

it works with no problem on the on board

I've had video fail from an improper dot-net install.

If you can do a fresh load of windows to collect all the other software you need. If not then run windows updates a few times, check the file system for errors (open 'my computer' right click drive, properties, tools, check for errors, say yes when asked to schedule), etc.

IF the BSOD is on one particular game then look to the game site for patches. Verify that other games work OK.

IF you have another PC you can verify the card is working. Bad card (not seated correctly, dust in the pcie slot or failed card) can cause this. Removing and reinstalling the card physically is something I'd do only after running with a know good windows install.

Aside, other fails like bas RAM can also cause this. If you are seeing other BSOD problems suggest you run memory diagnostic. But again I'd try to get the softwre right first.
