How to test motherboard after PSU Problem

My PSU killed my GPU and HDD and possibly ram, but the problem is, after i get new PSU(Enermax rev 730w, is it good :o?) I want to know how to make sure and see if each part is ok or not(half burned!!) Because if lets say my motherboard is damaged (im 80%sure) it might kill my GPU during a test!

So how to test each part with out risk of killing other parts? :o

    There is always a risk. Since your PSU killed pretty much everything in your computer, we can assume with high probability that this mobo is dead as well. I would not mess with it anymore. If I really had to, I'd get some cheap but working PSU, the lowest amount of cheapest RAM i can find around, avoid connecting drives, use the cheapest CPU for this socket and try using onboard VGA or CPU's integrated graphics / or some cheapo graphics card.

    For the PSU, I'd take something else. Take a look at this list and look at tier one, tier two (A) and tier two (B):

    http://www.tomshardware.co.uk/answers/id-1804779/power-supply-unit-tier-list.html

    XFX and Seasonic are good picks (550W for mid range single GPU, 650W if you have powerful single GPU, at least 850W for dual GPUs).

    P.S. I'm quite sure you'll find your old dead PSU in the above list, under tier five.
  2. Unless you have something like 100k$ worth of lab equipment to test each component individually using the appropriate laboratory-grade test equipment, there is no foolproof way of individually testing components. The most cost-effective small-scale method is trial by fire: swap parts, hope everything works or at least that nothing else dies.
  3. Thanks a lot, so your telling me even that i can turn on my pc with current stuff i should only take out cpu amlnd make almost a new build (ram gpu motherboard ?) Also my psu is persian brand, it has lots of fans here inclusing my cousin wich uses their 500w psu for 500w system thag the psu is always at a 100% and its 6 years its working, anyway im not gonna listen to him again, i will search the whole country and think of Green ad last option(uses seasonic stuff)
  4. Yeah man. Never cheap out on the PSU. There are 800W and even higher "claimed" wattage PSU's that can't deliver half of what XFX/Seasonic 550W can do. When buying a new rig, buy PSU first, then the motherboard, then everything else.

    ! Yeah psu wasn't cheap, I heard a lot about it but anyway, its so hard to find quality PSU here, even there's fake antec and .... PSUs

    But im a little confused, so my CPU is OK to go?? Other parts are not OK? I mean there's mobo and ram left only ! Anyway I will ask a repair center to see if they got a test device, if it was OK I sell it to my father's company for that cheap !machines :) but my cpu is expensive
  6. Your CPU might be dead as well, so be prepared for this. However, even if it is dead, it cannot hurt other components, you are safe to try it out. If it works, fine. If not - well, you'll need another one.
  7. Thanks :) will tell you reaults:!!

    Depending on how the presumed dead CPU died, it can have supply across power planes and those could certainly damage the motherboard's voltage regulators, the chipset or anything else connected directly to the CPU.

    The probability might be low since most CPU-related voltages are within relatively safe range from each other but it is definitely not zero.

    God jelp me, a little not: i ran pc for a hour after my GPU death with integrated, than safely manually turned pc off, im kinda sure it will work if i turn it Right npw but it might be half damaged! My cousin told me to dont worry at all! But seems he's wrong :s

    My cpu is so expensive i have to try it!!! Also i wish i could try others but its not Worth the risk;(

    That is the worst thing ever happened to me ;(

    Well, if your CPU can still boot using the IGP then that rules out most chances of catastrophic damage.

    Good, so, what i do tomarrow is first get a new PSU, (i have availability problem, may end up getting same brands PSU but just the OC series!) than a new motherboard (P8z77-v) and new rams (corsair vengeances 8gb dual chan 1600mhz) and use igpu for now because they might repair my GPU, and thats all? I don't think my expensive ssd is going to damage anything, also i booted with ram and ssd plugged! But i will get a new ram. Just not new ssd, and than that's all? Just want to be sure, first time something like this ever happened to me, my cousin says its because i restart a lot !

    Edit: wait , i thought of something, I'd of boots with same parts, than if they're damaged they're not gonna boot , so damage must at max give me a blue screen, not a short cruic right? Or the SC might happen when the test is running: o
    I know its risky to try new parts on old mobo, and psu (as you told me ;) ) but is it really risky yo try old ram on new motherboard and psu :! ?

    Yes, being able to boot using your old parts does imply a strong possibility that your remaining parts might still be good.
  13. Thanks a lot :Di hope atleast my CPU and SSD is ok, but it might not be, i had 2 blue screens 2 weeks before killing event ! Also ubuntu freezed like 4 5 times before killing the gpu !! Somebody told me im 100% that freezing and hdd problems you had were because of motherboard and psu damaged the mobo, anyway i will tell you what happeend im going to buy new psu today! !! Never swapped a cpu before lol ;)
  14. i ran memtest for 16 hours, 16 passes~ or 13 , no error, also i ran prime95 for like 1 min and nothing happened, now here come's the risky part, after i get my GPU from repair, (not sure if it was damaged and they only lied to take 10$ from me :D ) im gonna plug it to mobo and see what happne's i frist plug it to secondary PCI-e slot !!!
