System Wont boot

okay here is my problem: My system won't boot, sometimes. When it wont boot my mobo has a "troubleshooting LED" that comes on and indicates that it is receiving over voltage. Here is what i have for a system:

intel i7 2600k cpu
Gigabyte p67ud5 revB mobo
2x2g 1600 ddr3 kingston ram
radeon HD4650 (1g) vga
Coolmax 700w (CL-700B) psu

could the problem be the psu and if so how do i test it (i have heard you cant just use a multimeter)

  1. Hard to say. Could be the ps; coolmax isn't a very good brand, but some of the higher wattage units may be fine. I would contact gigabyte for advice. Use their online support form and give them 24 hours to respond. You may link this post to the form.
  2. Have you even try any trouble shooting? take out cmos and wait 5 min with power plug off... take out CPU and put it back in... Take out videocard and put it back in... if these doesn't work, than IDK what to do lol....
  3. did u do any overclock?
  4. @legend killer actually I RMA ed the original mobo got the revB and have done all of that
    @ BerylLee not with the new mobo
  5. Your CPU is dead, that's all i can tell you.
    BTW, to test your PSU, check this video of corsair:

    Buy new rams? get 8GB of RAMS as upgrade and sell your current 4GB ram for $10 or so lol...
  8. yeah maybe it boots fine on the cardboard after removing the battery so i know its not the board or the cpu perhaps its the bios i dk i tested the rails on the psu so thats not it all were good so i am going to try som different bios versions

    Go into bios, set CPU voltage and RAM voltage manually, auto can sometimes ruin your build... BTW, get a better Video Card :/, High-end CPU but lower-end GPU(GPU can be a problem too lol) and get 8GB RAM...
