What causes Blue Screening Parts?

[Bowkillaking]

Currently I recently just replaced my Hard Drive and I still get blue screens once and a while. What can cause blue screens? I just build this pc about 4 months ago. A few parts were from my old pc. Those parts are my psu, ram, and graphics card that I bought from my cousin a XFX 7850 Double D. Before I built the computer my bro said the blue screen was caused from defected hard drive (previous hard drive not current 1). So I replaced and the next day I still get blue screens when I replaced it. Could the problem be my ram? I have 3 sticks of ram 2 are 2 x 2sticks and 1 is 4 x 1stick. I would really want the screen to stop happening. Anyone know what could be the problem to it. What are the possibilities another defected hard drive?

Parts from old PC:

PSU: Asus 500 Watt
CPU: FX6300
GPU: XFX 7850 (full name shown above)

try running the system with just the 1x4gb stick in, remove the other 2. if that fixes the problem its a ram issue

Try removing the 4x1 stick for a few days or however long it typically takes to have bsod's appear. Also, your OS could be corrupt but I'd try seeing if there's a compatibility issue with the ram first.

I see that I just recommended the opposite of the above poster. Either approach is fine. This is slightly easier but I see the logic on his/her point too. I'm assuming the 2x2 sticks are identical.

also could you please post the error code that you get? that way someone can look it up and see what it means ( certain ones indicate driver issues, voltage issues etc)

What are the model #s of the DRAM, it's a definite possibility and may be a simple fix. Prob want the 2GB sticks in slots 1-2 and the 4GB in slot 3, raise DRAM voltage = ).05 and raise CPU/NB voltage to 1.2 and give that a try

So a minute ago it just blue screened on me I took out the 4x1 stick out Ill try what Tradesman1 suggests. I was afraid to mess with BIOS but my 2x2 sticks are http://www.newegg.com/Product/Product.aspx?Item=N82E16820231430 and my 4x1 (my bro took the 2nd stick) http://www.newegg.com/Product/Product.aspx?Item=N82E16820231428

Try what I said and manually set timings to 9-9-9-24 and DRAM voltage to 1.56
