So I was finally coerced into buying Overwatch, which meant I had to upgrade my graphics card. I got an ATI Radeon HD 6450 card for cheap, plugged it in, and things were good to go. I did get a BSOD while installing the drivers, but it was too brief for me to read, and I encountered no further problems after the install completed.
The problems started when my internet went out. Netflix stopped, everything was slow, so I just rebooted the router. It took awhile, but things slo(ooooooooo)wly came back.
I rebooted my computer, and once I logged in, everything froze. I hadn't had anything freeze like that since I tried to install an old wifi adapter, so I rebooted again just to be sure. It's variable what happens from then on, but one of three things will happen:
1. Fans at full speed, only thing that comes up is a blinking white cursor
2. Freezes at the Dell startup with blinking yellow squares
3. Get to desktop, then freezes
I've tried removing the new card, and what usually happens is the frozen yellow square thing. I can't get it to boot into System Repair, and I've tried making a recovery USB, but it freezes when I try to load it. I'm worried I fried the poor thing.
Edit: It is an Optiplex 760 running Windows 7.
Edit 2: One of the times I got a lower pitched beep and this http://imgur.com/a/GHpRS. I got to System Restore, tried to restore. Once it was done, it rebooted and I had some scary looking graphics issues while on the Dell splash screen.
Edit 3: Removed all peripherals except monitor and USB keyboard/mouse. I can get to Startup Repair, but each time I do, I get a BSOD saying "win32k.sys PAGE_FAULT_IN_NONPAGED_AREA"
Edit 4: Took out RAM and dusted it off and put graphics card back in. Was able to get into Startup Repair, but it failed. I was able to run System Restore, though. Once I ran it, the desktop froze and I had to reboot. I keep trying to download the driver for the graphics card, but the computer keeps randomly restarting. I booted it up again, and the blinking cursor screen turned orange.
