Can’T change screen resolution

Hey, guys.
My computer was just finished defragmenting my HDD when all of the sudden it logged off by itself and changed the resolution.
When I restarted it, the resolution 1440×900 had gone. And all of the sudden it doesn’t recognize my monitor anymore; it just says “generic non-pnp monitor”.
I tried to make a custom one on NVIDIA panel, but it keeps saying “test failed” when I choose the interlaced one.
My NVIDIA drive is up-to-date, and I can’t find the driver for monitor w19ev.
I’m on Win7 x64
Please help
Answer #1
"test failed" when I choose the interlaced one.
why you choosing interlaced, progressive (non-interlaced) is what you want ?
try uninstalling and re-installing your display drivers

Because when I tried progressive it looked really blurry. I tried uninstalling and re-installing my nvidia driver, but it’s still not working.
It only looked clear when I try 1440×900, 60hz, interlaced; but it keeps sayin test failed.
Answer #3
it looked really blurry.
you run the monitor’s auto-adjustment function
any chance you have a “restore point” from before the problem started ?
driver (7/vista)

Answer #4
if you uninstall the driver completely then windows should install a driver for you on the next boot.

I did, but no change at all man. Still blurry.

Unfortunately I don’t. This was my first instinct as well; to check the restore point

I’ve tried this, but it has absolutely no effect on the monitor.

But for some reason this damn computer decided not to.
