Power Outage problem. Computer not working

Ok So I built this computer in September of 2013, so everything is under warranty, manufacture that is. I got hit by the friday the 13th curse. everyday i leave the house I put my computer to sleep, which is surge protected. I come home after work to realize I lost power, A neighbor said it had been out for 3 hours. I try to turn the computer on it loads to windows and then 10 mins later BSOD and shuts off. It tries to restart itself, i hear the fans and lights going and 2 seconds later off and the same thing over and over. It was overclocked until after many attempts of it not coming on it boots normally, i get into BIOS and change to default settings. I load to windows 10 mins later.....off and back to the 2 sec on and off pattern. I talked to my friend who is a computer tech, he says it sounds like a PSU problem. He told me to replace it, so its friday and the only way im getting a PSU is from a store. I go to best buy, get a PSU, hook it up to my system. it starts up to windows and 10 mins later... off again. My friend says ok than its got to be the Motherboard, well I asked him could it be any of the other components, he said maybe and from there I tried the RAM test. Which is using 1 stick of ram at a time and starting it because maybe 1 stick could be bad. Nope still doesnt start. My friend says I need to RMA and PSU and the MOBO. I said what about the other components. He said dont worry about them until you get the new stuff in and can test to see if it was the MOBO that was broken. So now im stuck, idk what is broken, im afraid multiple things could be trashed so Im asking you guys what I should do. I want to just RMA everything because Im afraid multiple things could have been shot and I would hate to have problems down the line after the warranty is no longer good. So what do you guys say, just the PSU and MOBO and go from there. OR screw it and RMA everything just to make sure every component is good and take advantage of the warranty and get a better surge protector. Thank you guys for your help and sorry for my very detailed story. I will input my specs below.

CPU: i5-4670k
Motherboard: Asus Z-87 plus
Graphics Card: Asus GTX 660 ti 3GB
Memory: 2x8GB Corsair Vengeance
PSU: Cooler Master GX 750w

  1. Try repairing windows first then if it solves the problem no need to rma. Also restore the bios to default.
  2. Try to RMA the PSU if all else fails as coolermaster are not a trustworthy brand of PSU.
  3. Are you still plugged into that surge protector? If so, unplug your pc and plug it straight into the wall outlet and see what happens.
  4. ^ even if his surge protector failed Asus's inbuilt surge protector should have triggered, so other components should be safe. So its the psu which seems to fail at a certain load.
  5. Thank you guys for the quick responses. I have tried all that you have said before. I Have a backup hard drive with windows on it that I know works. Also I have tried to connect directly into the wall outlet and other outlets. Still the same result. Yes I am looking into getting a better PSU because I don't want this to ever happen again also because I haven't heard good things about cooler master PSU. Don't know why I bought it in the first place.
  6. I went to best buy and bought a different power supply just to test the system to see if it was the original power supply that wasn't working. Nope. Even with the new PSU all hooked up the computer still didn't work correctly.
  7. Duh, okay what psu did you buy? If the psu is ok then Maybe the motherboard is faulty. If the onboard surge protector was not triggered then you can request Asus for compensating for any burnt components.
  8. I got the corsair cx 750. (The green one). Also I haven't not gotten any error messages about the Asus anti surge protector being tripped. I don't think it was.
  9. Or it could have been but is not working correctly.
  10. CX 750 is a OK unit but 100times better than any CM unit. Then your best bet would be to RMA the mobo and then check other parts. Also ask them if their policy states for any sort of compensation.
  11. OK should I RMA any other parts. I'm not sure what is working correctly. Since the Asus anti surge protection didn't go off could other components have been hit by the surge and possibly hurt them and their life span?
  12. Best answer
    Thats why i am asking you to phone asus and you should do what they say.
  13. If they were really hit by a surge possibilities are high that they are fried.
    Do you have any friend or relative on whose pc you can check your components?
  14. Haha I wish. The friend closets isn't really that close lol. I'll talk to Asus tomorrow. I'm sure the process to prove that they are the reason will be nice and long lol.
  15. Rounakr94 you have been a great help. I appreciate you sticking around and helping.

    Not one reason exists to suspect a PSU. Your computer tech did what most do when computer hardware is mostly unknown. The technique comes right out of the movie Casablanca. "Major Strasser has been shot. Round up the usual suspects."

    Parts were replaced only on wild speculation. Even symptoms do not indict those parts. However you had a BSOD. Apparently assumed numbers were useless because you did not understand them. Well, had you recorded those five key numbers, then the fewer who know this stuff would have isolated it to only a few parts. Without numbers, then everything remains suspect.

    Now, if a power system (which is much more than a PSU) is problematic, then a simple tool said so with certainty. A tool sold in Walmart and used by junior high science students. That tool, one minute, and directions result in numbers. Those who best know hardware can only remain silent without those numbers. With numbers, the suspect or exonerated part is known without doubt or speculation in a next reply. And says why that part is suspect.

    After so many posts, you still suspect everything. Therefore nothing was accomplished. You do not even know if the power system is good. No one even said why a PSU is be suspect. That alone should have made you wary. A recommendation without the ‘whys’ is classic shotgunning.

    View system (event) logs. Windows routinely works around problems, records that problem in logs, and moves on Long before suspecting anything, first hard facts (and numbers) must indict the suspect part or adjacent criminals.

    Only two techniques exist. First is how professionals do this stuff. As defined in a TV show CSI. "Follow the evidence". Hard facts and numbers. That means ignoring symptoms and speculation (ie bad power supply).

    Second technique is shotgunning. Keep replacing good parts until something works. Don't ask anyone else. Better is to use dice or convenience to select the next suspect. How many forget to mention other parts of the power system?. Shotgunning is used when many do not even know, for example, what a power controller is. No reason to know that. Just shotgun.

    Either provide hard facts requested (ie meter numbers, BSOD, event logs, etc) and ask how to get those other numbers. Or keep buying new parts randomly and reloading Windows until something works. If shotgunning, then nobody here will be any more helpful. Many accused the PSU only because Major Strasser was shot.

    One final point. Surges occur maybe once every seven years. If you had a surge, you probably have other damaged appliances. Surges often too smal to harm a computer also damage traditionally undersize power strip protectors. Surges are a ghost that is blamed only when others have no idea how hardware and electricity really work. Nothing in any post even implies the existance of a surge.

    The word surge defines many different events that have nothing in commom. A USB surge to too much current. A surge protector surge is 120 volts maybe increasing to 1000. An Asus anti-surge is about motherboard voltages dropping. The word surge has as many meanings as pigs feet, fingers, and chicken fingers.
  17. Not really surges in Asia are common thats why I have an ups which acts as surge eliminator. That GX power supply is shit, if the power supply was working correctly then its protection features would have been tripped. Now that the OP has a better power supply he should be safe from that side.
    P.S.: keep the old psu for testing fans and emergency testing incase the CX fails.

    No protection feature 'trips' in a power supply. Surge that does not do damage is easily converted by a PSU into electricity that powers semiconductors.

    If destructive surges existed, then CFL bulbs, dimmer switches, and other appliances with less robust protection are also failing. How often are those damaged? If not, there where is this surge?

    A surge incoming to a UPS is simultaneously outgoing into the computer. It is electricity. If both incoming and outgoing path does not exist, then an electric surge does not exist. Also read UPS spec numbers and its near zero joules. Where is this protection - a surge eliminator? Exists in hearsay that also claims surges occur hourly. Two more reasons why hearsay claims UPS protection while UPS specification numbers say otherwise.

    If a PSU protection feature trips, well, a useful claim always says what and why. So that the reader has good reasons to believe it. What is this part that trips? Why does it trip? Where are manufactuer spec numbers that define this tripping? If those questions cannot be answered, then hearsay was misrepresented as facts. Never accept an answer only because someone said so. Useful answers also say why.

    That PSU did not trip for the same reason other supplies also do protection without tripping.

    Nothing but hearsay exists to say a PSU was defective, was shit, or was damaged by a surge. Missing specification numbers also invented something called a surge eliminator.

    If a PSU is damaged by a surge, then reasons why we know were also posted. And what inside was damaged. Only speculation comes without fact and numbers; and a fear of surges that magically do not damage anything else.
