Laptop Running Slow/Freezing/Screw Skews

Within the last two days my laptop has went to crap. Received it for Christmas this year, has run fine. It's a Acer Aspire, AMD, 4 GB Mem, 500 GB HDD. It's running Windows 7 (Came pre-installed). I'd get you the rest of the specs if it wasn't for this issue. The other day I was lofting around while the laptop was running. I noticed out of the corner of my eye the blue screen of dead (Hereby referred to as BSOD) had popped up. Before I could try to read what it said, my laptop had restarted. It restarted completely fine, no issues had been noted. Two days later, I was closing Mozilla. It normally asks me if I want to save my pages so that when I reopen Mozilla they'll instantly load. When I closed it expecting this message, I got the BSOD again, this time I managed to note down that it said "pfn_list_corrupt" before resetting. I googled the issue to no real avail. This time however when it restart it was running noticeably slower than normal. I had to go so I quit my research and left, taking my laptop with me. When I got to my destination, I restarted the laptop, this time noting that the laptop completely froze on my desktop. Nothing responded, mouse would not move, no buttons responded. I held the power button, restarted it, and this time it was running extremely slow for about 10 minutes before freezing again. It has been freezing and/or running slow then freezing since. The odd time the whole display will skew colours that will look almost like spikes protruding from the left and right sides (Only using the colours of the desktop however. It's not inserting it's own colours). I can boot it up and have it run fine in safe mode. I ran various Spybot/AVG/Malwarebytes in safe mode quickly with no problems found. Ran CHKDSK, no problems found. The HDD is FAR from full (Not even 100 GB's used, I'd say probably ~60 at most). I've come to eliminate software as the issue due to the fact I've not installed anything new, updated anything, or changed anything software wise within Feb. and this only began occurring 2-3 days ago.

 

**I apologize for the double post**

Update: I just attempted to restart it once again (I left it off after the last attempt) and this time it froze roughly 3 minutes after it loaded the desktop (This is where it's been freezing before, I've enabled and disabled different start up programs so that just the bare minimum required were running to try and eliminate software once again. No avail, still froze) however this time after it froze, the screen went completely black several seconds after attempting to move the mouse.

**Again, sorry.**
