Hi all. My name's Liam and I'm new to the forums.
About a week ago, I bought a second hand pc from a guy with the intention of gaming. I got the computer last night and it was running all fine and dandy, and I spent most of the night installing microsoft updates.
When I got the chance I used a usb to install the drivers for my wireless network adapter (PC has no optical drive), and the wireless was set up fine.
Afterwards I downloaded AVG free and Malwarebytes Anti-Malware, these both worked fine also.
Before I went to sleep I had League of Legends downloading, and I awoke during the night to see it had finished. All good there, I shut down the computer and went to sleep.
When I woke up I booted the PC. The blue light turned on and I could hear the fan working, however, my mouse/keyboard hadn't lit up yet and my screen said 'HDMI no output', and nothing was on screen. I turned off the computer and restarted it about 3 times with the same problem, until I finally got to an ASUS screen that said 'overclocking failed' and had me look at all the computer stats and such. I wound up just booting it normally and it was running fine, for about 5 minutes.
I got onto google to search the problem, and my screen turned white. Nothing happened for a while, the PC was still running, my peripherals still working, but I couldn't do a thing, so I shut down the PC using the turn off button.
The same thing happened again, took about 3-4 tries and it booted again, but this time with the 'System didn't shut down properly' screen. I chose to boot it normally, and after about 5 minutes (while I was browsing the internet for solutions), the screen stuttered and turned to a mess of vertical purple lines.
I left it for a while after turning it off, and (yep, you guessed it) after 3-4 tries I booted it again. Now it's running fine, I'm installing updates and restarted my PC to install them properly and it's fine.
I'm worried to turn off my PC now, and was wondering if anybody could shed some light on all of this. I'm a bit of a computer amateur, so me opening the case and taking a look is probably out of the question... here is a list of my parts according to the auction - http://www.trademe.co.nz/Browse/Listing.aspx?id=914220703
AMD FX 8320 Black Edition 3.5Ghz 8 Core
Asus M5A97 Evo R2.0
Power colour HD 7850 PCS+
FSP Hyper 500w PSU
Cooler master Case K280

It was given a fresh install of windows but I had to do all of the updates myself.
Thanks a lot for any help
