So, in the past 2 months, my PC has started doing some really weird things.
~~~~~~~~~~~~~~
It all went nuts ever since I accidentally knocked my graphic card out of the mobo's socket when I tried to plug an HDMI cable in (my friend didn't screw it in properly). I put it back in, but I noticed my monitor was losing signal, so I re-opened my PC to push it into the mobo a bit harder.
Ever since I did that, my PC has been doing all sort of weird stuff. First, right after I put the card back in, my PC took longer to boot into Windows every second time. It'd take it 30 seconds, then a minute. 30 seconds, a minute. Etc, etc.
That magically stopped one day, but then, it suddenly started taking a lot of time for my PC to restart. I had to force it a few times, but now that suddenly stopped as well.
After that, my PC refused to open HP Printer Assistant for my printer's options. As if it was all gone. Thankfully I worked my way 'round that and found most of the things I needed for my printer.
There were some minor glitches after that, with My Computer taking forever to load, or my user icon was doubled, but it was all fixed after a restart.
And now, the worst thing of it all, random shut downs. But not when I'm doing something, but when I put it in Sleep Mode. It stays like that for 10~30 mins, then it shuts itself down. I turn it back on and of course, I get a BIOS message that Windows was not shut down properly, so I just continue as usual. I checked the Event View and got a critical message from Kernel Power thing. Honestly I have no idea what is that.

So... does anybody have any clue what the hell is going on? Is it Windows? Could have I damaged something on the motherboard? PSU failing? Something else failing...?
All temps are fine by the way. I have an AMD FX-8350 running at 35 Celsius degrees, and pretty much everything else is running at that temp or lower except for the GFX, which is at 45 Celsius degrees on idle. CPU usage is always at 0~7% and RAM is at 15%, so I don't think those two things could be culprits.
Also, I'm using Windows 7 Ultimate 64-bit.
