The problem started a couple days ago. I would start my computer and everything would be fine until after the “Welcome” screen on Windows. When the desktop should be loading, the screen would instead turn into a garbled pink mess. No input would work from the keyboard or mouse. I would have to turn off the computer and turn it back on. The problem has progressed over the week. Sometimes the screen would just go black. Sometimes I could hear the opening Windows chime although it was full of static. The last thing it did was give me a screen full of garbled colors and I was able to see a block instead of a mouse pointer.
Windows 7 Home Premium 64 bit
Nvidia 680i motherboard
Nvidia Geforce GTX 280
Intel 320 SSD boot drive
2x WD 250GB in stripe mode
Antec 1000 watt PSU
This always happens after the “Welcome” screen when the desktop should load.
If I hit the restart button instead of power button the BIOS will not POST. BIOS has most recent update.
Safe mode always works perfectly.
If Windows manages to load in normal mode it will work perfectly. I can watch movies, play games, do whatever. I can leave it on overnight and use it fine the next day. As soon as I turn it off and turn it back on, I'll start having problems again.
So far I’ve tried installing the GTX 280 in a different PCIE slot but it didn’t change anything. I tried installing the GTX 280 in a different computer and it worked perfectly. It worked with the windows driver and with the newest nvidia driver. The weird thing is that I tried the other computer’s Radeon 5870 in my computer and it also worked perfectly. It worked with the windows driver and the newest AMD driver. When I put the GTX 280 back in, it went to crap just like before.
The other computer that works:
Windows 7 Home Premium 64 bit
Asus P6T Motherboard
WD VelociRaptor boot drive
Maxtor 1TB storage
Same Antec 1000 watt PSU
the nvidia forum has a giant thread with about 55,000 views about a very similar problem. I couldn't find a definitive answer for why this is happening though, and no one else had their card work in someone elses computer. I know the card is good because it works in another computer. I know my motherboard is good because a Radeon 5870 works on it. Maybe the PSU?
Well I swapped PSU's and my computer works perfectly. Now I just need to see if this PSU (Antec True Power Quatro 1000 or TPQ-1000) is still under warranty. Case closed, thanks for reading, letsgotoschool.
OK. When I used the other power supply I turned my computer off and on numerous times and it worked every time. Now I have installed a brand new 650W Corsair and I still got a pink screen! What is going on!?
Tonight was an adventure. Since it wasn't the power supply I was convinced it had to be a software issue. I researched how to completely rid my computer of anything nvidia. Basically I manually uninstalled nvidia stuff using Programs and Features on the control panel, saving the actual graphics driver for last and skipping motherboard stuff. After a restart in safe mode, I manually deleted anything I found in Program Files, Users, etc. Then I went registry diving and deleted global and installer under software/nvidia. Then I downloaded and installed Driver Sweeper 3.2.0 and had it analyze then clean nvidia display and physx. After a reboot in safe mode I installed the latest drivers (296 I think) and everything is fine now. We'll see if it lasts...
Well it got to the point where I formatted my hard drives and installed a fresh Windows 7 hoping that would fix the problem. It didn't. I had to use my last LAST resort: bake the graphics card in the oven. I disassembled it, baked it at 385 for 10 minutes, reassembled and reinstalled. It has been working perfectly for a month now. I've been using 257.21 drivers because I read in another post here that anything past 260.xx is no good for the GTX 280's.
