Computer slows down after/during gaming then eventually freeze.

Hello, I am new here so sorry for that. I just need to ask some experts here.

I got a PC which is 1.5 years old but I encountered some problems 1-2 months ago. I didn't care to check it out since it didn't happen quiet frequently. Now my computer freezes several times a day and it's not only when I am gaming. It happens also when I just surf the web but not as frequently. I had some bluescreens that said memory management failed before this happened. Got Bluescreens every 2-3 days now there is no bluescreen just completely freeze until I force shutdown.

My speccs are:

CPU: Intel Core i7-2600K CPU @ 3.40GHz
MB Brand : Asus
MB Model : P8P67 LE
SB : Intel P67 rev B3
GPU Type : NVIDIA GeForce GTX 560
DirectX Version : 11.0
RAM : 8192 MB DDR3 Dual Channel
RAM Speed : 686.8 MHz (1:5) @ 9-9-9-2
Slot 1 : 4096MB (10700)
Slot 1 Manufacturer : Kingston
Slot 2 : 4096MB (10700)
Slot 2 Manufacturer : Kingston
(DIRECT COPY FROM CPU-Z)

This is driving me crazy. For example after a fresh restart I open Dayz then I have 70+ fps stable then after 10 min the fps drops to around 50 then after 20min I got 30 stable then it can drop down to 15 and computer gets extremely slooow. Does not matter if I close the game or not... the whole Windows OS gets slow and unresponsive until after a while it locks up and freezes.

It's not the temperature as I've had HWmonitor during the time I experienced lags unless you call 50C for graphics card and 66C for CPU as high. My CPU isn't even working at full speed so it isnt the CPU that is causing this lag.
I tried SFC/ Scannow and no problem.

I need to know what to do!!!! Please help.

I hope I am not much of a trouble. Thanks and sorry for my english.

    Ok thank you very much. I might also add that I used to multibox but recently when I open for example 8 instances of world of warcraft then the whole computer bsod. I guess I'll try memtest since I am kinda sure its my ram memory. I'll come back tomorrow if I cant find any errors.

    Thanks again.
  5. Download and run OCCT ..... do the CPU and GPU tests .... make sure you do not have any other hardware monitoring utilities loaded when doing so.
  6. Update

    I had it running over night but just after 2 min of launching the testing I had the first error...
    Then I went to sleep and this is what came up

    I might also add that my computer lags even more after this test.... it lags after the restart.
    My cursor also has very odd big and wierd graphics that looks like a rainbow. Its not a virus since Ive already done a search twice.
  7. How Can I run memtest in BIOS? I dont know help :(
  8. I bought new ram now but i wont open the package since i am not sure if I should actually switch them. still need an answer :/
