Black64 Posted May 30, 2013 Posted May 30, 2013 So my PC was working fine last night, and I turned it off, pulled out my 6950 and installed my 7950. Turned it back on it said missing hardware to boot, took out the 7950 and out back the 6950 and it said no OS installed. weird. So then I turn it back off and on and then it said please insert a bootable media. At this point I thought maybe my SSD failed or my Mobo was starting to fail. But troubeshooting proved that both were fine. Problem SSD wouldn't boot after new GPU installed Efforts to fix 1.checked cables 2. checked bios and was able to see all HDD and SSD 3. checked the HDD setting was to IDE 4.unplugged everything except for the bootable SSD 5.ran windows 7 repair 5 times (could not see the OS on the SSD) 6. went to format the SSD but all files were there and so was the windows install 7. plugged the SSD into another PC and it was fine 8. Lot of Google research 9. tried to fix MBR 10. tried to scan for viruses. Solution Resintalled Windows and that fixed it. Everything works fine now. Total time 3.5 hours I didn't lose any info as all of my stuff is stored on my other HDDs, my SSD main boot is designed to be wiped/lose everything at anytime for times like this. But I am at a loss for what happened? Any ideas? Share this post Link to post Share on other sites More sharing options...
wevsspot Posted May 30, 2013 Posted May 30, 2013 Black, I've experienced numerous times when using the latest and greatest GPUs that an update to the motherboard BIOS is due (and hopefully they are available at the time). If I have an issue installing a new generation GPU the first thing I do is check to make sure I'm running the latest motherboard BIOS. Then of course during the installation process, make sure that the power supply is disconnected from the outlet and that all residual energy is discharged by holding down the power button for a couple seconds. On the front end, I always ensure that the power supply is capable of handling the power requirements of the new card being installed. And I ALWAYS delete the video card drivers from the previous installation before I install a new card. I run the regular uninstaller and then also use Driver Fusion in an attempt to zap anything relating to the previous driver installation. I install the latest video card drivers after I've installed the new card. I do this even if I'm upgrading a card from the same chipset maker (i.e. AMD, nVidia - 6950 to 7950 etc.) Share this post Link to post Share on other sites More sharing options...
IVIYTH0S Posted May 30, 2013 Posted May 30, 2013 Glad you sorted that out, can't say that's ever happened to me lol. I haven't reinstalled my OS in years Share this post Link to post Share on other sites More sharing options...
AkakmanH Posted May 30, 2013 Posted May 30, 2013 I used to have the same kind of problems. Several years ago, while troubleshooting a GPU problem, I spoke with a MS tech about the problem. While trying to fix the problem he asked if I had deinstalled the old GPU before installing the new one. Of course, my answer was 'no'. Since then I always deinstall the GPU hardware before shutting the computer down. In almost all cases, the new GPU comes right up because the OS has to look for new drivers.

bigball1 Posted May 30, 2013 Posted May 30, 2013 I had a very similar issue. I installed more ram into my system and it killed my raid ssd setup. I went from 8 to 16gb. I had to reinstall windows as it would not boot fully into the OS. No idea what happened. Share this post Link to post Share on other sites More sharing options...
Black64 Posted May 30, 2013 Posted May 30, 2013 I've heard stories about that happening with ram as well. But what's strange is I couldn't even get past the BIOS, it's like it didn't want to see the OS. But it saw all of the HDDs fine. Should I be worried when I put in my second 7950?

wevsspot Posted May 30, 2013 Posted May 30, 2013 You shouldn't have any similar issues when you put the 2nd 7950 in. Your drivers are apparently working ok now, and your motherboard seems to be dealing with the new GPU, so I wouldn't anticipate any other problems.

Black64 Posted May 30, 2013 Posted May 30, 2013 (edited) I hope so, I don't want to install windows again. I was thinking it would have been a virus or could this be a direct result of not uninstalling the drivers of the 6950 first?

EuroFight Posted May 30, 2013 Posted May 30, 2013 If it was Windows 7, it may have something to do with that 100MB 'System Reserved' partition getting corrupt? I have no evidence to base that assumption on, only that it holds the boot instructions for the OS. Share this post Link to post Share on other sites More sharing options...
wevsspot Posted May 31, 2013 Posted May 31, 2013 Black, now that we have the full report, if I were to nail it down to one thing my best guess would be the failure to remove the previous driver installation. Again, I can't stress enough for everyone else. If you buy the newest generation video card it is always a good idea to check and make sure that you are running the latest BIOS revision for your motherboard. That is always the first thing I check before I proceed with a swap or upgrade. Share this post Link to post Share on other sites More sharing options...
d6bmg Posted May 31, 2013 Posted May 31, 2013 It looks like something related to driver conflict issue. Your motherboard is fairly older than the current generation of graphics card. So, it might have caused some temporary compatibility problem? I'm glad that the OS re-installation have sorted your problem out. And I don't think adding another 7950 could create problem as you are running one already. Share this post Link to post Share on other sites More sharing options...
Black64 Posted June 3, 2013 Posted June 3, 2013 Well I just installed my second 7950 and the bios changed the boot order and said overclocking failed. I went and changed the boot order to the correct order and rebooted. everything works fine. Strange. Share this post Link to post Share on other sites More sharing options...
