I've had this computer since June 2011 (nearly 1.5 yrs now?) and I've been having some really weird issues lately.
About 2 months back, while browsing the internet, my cursor would randomly freeze and get warped and yellow, freezing the computer every 5-20 seconds until I restarted it. (I have pics of the mouse pointer if needed) This problem would only happen ~once a week, so I had attributed it to just windows degrading or something similar to that.
A bit later, it started complaining about my paging file. I can't remember what it was exactly, but it would create a new one every 10-15 restarts, and give me notice. I went through the standard procedure for fixing paging file issues, but I still have it to this day. A little while after, my C:/ drive started getting full. With 512gbs of storage, it got cluttered by fraps videos, and I left it like that for quite a while, not knowing that it was the fraps videos.
Now here's the kicker: Half my RAM stopped working!
My computer started giving me "Your computer is low on memory, please close -game I'm currently playing- to prevent a crash"
I ignored it at first, until my computer crashed. Oh joy. Ran a virus scan, nothing found.
I then looked at the windows summary screen, and it told me that only 3.99gbs out of my 8 total were useable.
So something cut my RAM in half.
My friend who knows everything, and was trying to help me with my previous issues with no dice, suggested I use something to find out what was cluttering my harddrive, and it showed me to the fraps folder, after which I deleted 125 GBs' worth of data.
Now, my RAM is still crippled. For some reason that is confusing to me, my laptop with 4gbs of RAM can play games that my crippled tower crashed with.
So, my friend told me stuff about RAM, why it stops working etc. He said it could be because it's overclocked. (note: store did the overclocking)
I have not tried to jiggle the RAM around yet.
After every time my computer crashed because it ran out of RAM, or after I restarted it after the mouse issue, it would turn on, but the TV which I use for a monitor would not recognize it, so I would have to press the power button to turn it off and restart it again.
Now, after my latest crash when I tried to play a PS2 game that I assumed it would handle, I can't use it anymore. The TV refuses to recognize the computer. I've tried messing with channels, jiggling around with the cable, nothing works.
I can now not use my computer.
(I haven't tried a different monitor/TV, and I'm running windows 7)
I can get the exact specs through TeamViewer, using my laptop. I can also use it to remotely run the computer as normal.
