Hi folks,
About a year ago I built a PC running Win 7 Ultimate with a 60GB SSD, 8GB of RAM and a Gainward GTX570 GPU for video editing.
The computer worked perfectly fine until this evening, when speckles started appearing on my screen and Windows started repeatedly freezing or crashing with a BSOD.
The situation deteriorated rapidly to the point where, now, if I boot up, this is what happens:
1. The Intel BIOS splash screen has artifacts: streaky lines all over it.
2. The screen alternates between being blank and being filled with multi-coloured streaky lines, the kind you used to see when old arcade games booted up.
3. Windows goes directly to safe mode. It doesn't even give me the option of starting Windows normally, it just goes straight to safe mode, using the bog-standard VGA driver.
4. After Safe Mode starts, I get a message saying "Please reinstall/update the display driver and program." There's a little triangle and exclamation mark on the GPU in the Device Manager. It says "Windows has stopped this device because it has reported problems. (Code 43.)
Thinking it was a corrupt Nvidia driver problem, I installed the latest drivers. Didn't fix the problem. I rolled back to drivers from late 2012. Didn't fix the problem. I rolled back even further to the original drivers from my installation CD. No dice. Each time, I've selected the "clean install" option but no luck.
I tried switched from HDMI connection to DVI connection. No luck. I've run Advanced System Care several times. No luck. I've run a Windows disk check on startup. The problem persists. I'm not sure what else to do apart from send the card back under warranty. But I've been thinking: if the card works fine in safe mode, without me getting any BSODs or artifacts, then surely it must be a driver issue, mustn't it? Any thoughts? Suggestions? I've taken screen shots of the bootup screens on my digital camera if anyone wants to take a look at them.
Thanks in advance for any help you can offer.
