Overclock issues with AMD Athlon II X4 640

Specs:
OS: Win 7/10
RAM: 16Gb
CPU: AMD Athlon II X4 640
GPU: Gigabyte Radeon R7 260x


I recently decided to try overclocking my computer after it working fine for a couple years. I overclocked my gpu with msi afterburner without a hitch. I then used the bios to overclock my cpu by 15% as to not push it since im air cooled. I had no issues once it was tweaked, for about 3 days. Then today my computer started freezing either on boot, right after, or after abo 5 min of use. I reset all my bios settings and nothing changed. i tried deoverclocking, tweaking more, and maxing it out with absolutely no change. Im due for an upgrade anyway but what im trying to figure out is if my cpu done, or if im missing something. Also a note to add is i tried messing with voltage, mhz, and auto/manual settings and my temps stayed below 55 °c throught everything.

  1. Does it work on stock speeds?
    Try different RAM? Running on a different power supply or video card?

    Ive tried resetting the bios and cmos as well as setting to stock stats. So no, stock speeds dont do anything. My video card ive tried deoverclocking, that which, did nothing. And i dont have an extra power supply but mine has plenty of wattage so that shouldnt be an issue. Also i did have two types of ram installed so i tried only using one type to which, nothing changed.

    Wattage of the power supply is only one part of it, there is also the quality of the power supply. You may have a ton of crap, but it's still just a lot of crap.

    It may be a dead CPU though, but no good way of testing that unless you move it to another system and it does the same thing.

    I purchased and installed a new cpu today, AMD FX-8320, and my system has worked perfectly fine since. thanks for your input and help narrowing down. now to never overclock my cpu again XD
  5. My gut tells me PSU problems. A tower freezing and never unfreezing tells me there is something wrong with the voltage. Start here. A dead CPU is highly unlikely, especially on the 640 which were overclocking friendly.
