Geforce GTS 250 jumbled image, need help

post #1 of 6
Thread Starter 
So I just re-installed windows recently and have been trying to get all of my favorite apps back. It was working perfectly, until.......
I tried flashing my video card's BIOS

So I got my BIOS with GPU-Z, modded it with NiBiTor, then flashed the new one on, in windows, with nvflash. Everything went smoothly. But then when I restarted my computer, after it showed the Windows boot screen with the glowing logo, The screen got completely jumbled so that it looked like a pile of dead raccoon was smeared accross my screen.

Odd thing: Safe mode works.
Gay thing: I can't flash back to the original BIOS.

I have tried running nvflash from safe mode, and 2 different USB flash methods. Trying it in safe mode didn't work and came back saying "could not start service." I tried enabling its service, and even tried to have windows load the nvflsh32.sys & nvflsh32.sys drivers with safe mode, but that didn't work. Then I tried 2 different USB boot methods, both giving the same thing when I tried to run nvflash: program can't be run in DOS mode.

I GIVE UP!

Anyways,

Think we can safely assume it was a bad flash and don't need to rule out the card being the cause.

As for a solution, I'm not completely sure, trial and error sounds best.

Possibly boot up using your integrated card, and still leave your 250 connected and flash it.

I see your mobo only has HDMI out for integrated video, I hope you can use that.

If not, put in another card, and dual-boot cards, not SLI them, just dual boot. So, you'll have the other functioning card making the system usable then, you can flash the bios for the other card.

Don't worry m8. We'll figure something out. I had similar case with my 9800GTX+, but not with the BIOS flashing part though.

Might a dumb question, but did you setup your USB flash drive to be bootable?

If you not you need to download HP Drive Book key Utility

Then download Windows 98 Boot files Unzip them...


1. Install HP Boot utility. Run it.
2. Choose the appropriate drive
3. Check "Quick Format" & "Create a DOS startup disk"
4. Click on [...] to browse for the windows 98 boot files. Click "Start"
5. Copy two essential NVFlash files to the drive and the BIOS, of course.
6. Restart the computer, choose to boot from the flash drive (i.e. on my board it's F9 key)

Then flash it back to the old one...

Well, what I think is happening is the card is working in normal mode in Safe Mode with its native clocks, because its driver is not loaded. Then in normal Windows 7, when it loads the card's proper driver, it puts the card into 3D mode, or Throttle mode, or Extra mode, and one of those clocks that I changed in the modded BIOS is wrong. It also does this when I try to load into normal Windows 8 Pre-Release. That is why I think that it is the card's BIOS. I will try loading the onboard video with the card still in it after I get back from work. Hopefully that will work!

PS: I wrote the post when I was tired yesterday. Forgive my ill-placed words.

Thanks Ascii Aficionado. I couldn't boot up with integrated video with the card still in. Instead I took the card out, then booted with integrated video, then when Windows was up i put the card in. I was then able to flash it. Everything is working now!

Do not try what I have done unless you really have to. As I tried putting the card in while the computer was running my finger got caught in its very sharp fan and was cut up pretty good. Watch your fingers!

I bled on my old ram as apparently when I was putting my old card in a year ago it cut me. Previous ram/card, not what I'm currently using.

"Insert bleeding/cutting edge ram joke here"
