Specs:
-Windows 7 Home Premium 64 bit
-I5 3450 Processor @3.10 GHz
-Nvidia GTX 660 TI
-Thermaltake 850 watt power supply
-Seagate 1 TB HDD (no clue what the speed is)
-Asus Motherboard (someone at my house decided to throw away the box so i have no clue what the specs on it are)
-Basic CD drive

Well, Basically my computer was running fine the past 3-4 months i've had it, and all of a sudden it started giving me a referenced memory error from wermgr.exe or something close to that. I haven't altered anything, installed anything new, or any of that. It just decides to give me that error for some reason. I looked up on the Microsoft forums and they just told me to turn off the windows error reporting service (they have no real solution to solve it). That worked for a while. Now my PC is having hiccups in its speed and performance. I play this game called "World of Tanks", and i'm getting about 90 FPS in it with 50ms ping and no lag connection wise. I'll be playing just fine and all of a sudden it will freeze up, and the HDD activity light on the front of my PC stays on constantly, no flashing or anything, then my computer goes in a massive melt down type of thing. It gets so laggy, freezy, and slow that i have to restart. It does this with any other game i play too. For example, My buildings and cars wont render in Grand Theft auto IV. Same for ArmA II, ArmA 3, Company of Heroes, etc. Two days ago i woke up and my PC was shut off for some reason, i turn it back on, and the damn thing doesn't even know how to start it self up. So i go into the BIOS motherboard setting upon start up and it doesn't have the HDD selected as the primary boot media device. So i get that sorted out, and after multiple windows repairs and multiple safe mode attempts, i get my PC up and running again. Then, the next hour or so after, my computer decides to shut it self down. Upon start up once again, I get a screen that says, American Megatrends, And I can't quite remember what it said, but I remember having to push F1 to repair or set something up in the BIOS. Then i get my computer up once again. Now i can't even play any games at all without it freezing up in the first 10 darn seconds! I don't know what in gods name happened but my PC barely knows how to run it self anymore. I checked for viruses with Norton, it removed 15 tracking cookies, not really anything important. Launched my games again, and no luck. Now i've resulted to this forum for help. If you need more details (i know i suck at explaining things thoroughly) please reply with your questions and i will reply as soon as I can.
Thanks in advance, Austin.

PS. I have no clue what is causing this, My hard drive, Processor, busted RAM, not enough power to modules inside my PC, overheating, etc. Im looking into getting a new processor and RAM.
 
Solution
Yes, hard to say for sure without swapping parts.
Regarding the memory, try leaving single RAM stick installed and test for a while.
For the HDD, is there one available that you can install Windows on it, just for testing?

I'm getting new ram anyways, so if that fixes it ill let you know, and i dont have an external HDD or another hard drive around to test. Also, If i format my hard drive, will I have to reinstall windows? If so, there is a sticker on the side of my PC that has a code for windows 7 installation, If i've used it once, will it not let me use it again?
Thanks in advance

I bought the PC from cyberpower PC, i changed the graphics card and the power supply,I still have the CPU fan that came with the processor on, should i invest in a heat sink? if so, please send me a link to a decent one for a good price.
Thanks.
