Computer Turning On and Off repeatedly

ok
first i started having bsods
(not really doing anything intensive just watching youtube videos or surfing the internet)
so i just restarted the computer and the bsods went away
then i had another bsod and this time when i tried to restart once it got past the bios logo it would give me an automatic bsod

so went to go and troubleshoot
and moved the computer to a place where i could take it apart and such
when i did i just tested it again just because
and instead of giving me an automatic bsod it wouldn't even boot
it would turn on for a few seconds (fans) and then turn off in like intervals not stopping till i cut the power
after this i tried things like taking out the graphics card
and that kind of stuff still the same problem
i read somewhere that it could be the power supply
so i went to best buy and bought a new power supply
the same thing happened.....
so i decided to see if it was my mobo/cpu (didn't reapply thermal paste)
so i got my old one out and tried running it and instead of going in intervals it just stayed on but nothing would show up on screen and the cpu fan wasn't running (new powersupply and old one same thing)
other fans were moving including the graphics card
so i am stumped at what to do and whats wrong

my specs are
i5 2500k
coolmaster 212+
gtx 560ti
asrock extreme3 gen3

old mobo/cpu
amd phenom II 840
asus m4a79xtd evo

PSU:
corsair
gs 600 (old)
gs 700 (new)

is asked here first
http://www.overclockers.com/forums/showthread.php?t=723357

and it was said that it is possibly the motherboard
(i returned my gs 700 to best buy btw)
b/c i returned the psu i bought another just bc
i bought a MSIZ77A-G41 Z77 mobo and
a psu seasonic M12II 620W
and arctic silver 5 thermal paste (removed and reapplied)
and I am still having the same problem

could the issue be in the RAM or CPU?
my parents are considering just buying a brand new computer from like best buy or something

edit: also i was just rereading this thread http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems
and i realized that i had extra standoffs on (two to be exact) i removed them and still have the same problem
(didnt really think it would change anything)
so would i have another faulty motherboard or would it be my cpu, ram or my gpu?

More about computer turning repeatedly
  1. It's probably nothing to do with the hardware, most likely a driver issue in conjunction with running the browser with Skype or Media player or iTunes or some othe app. There was an issue recently about IE9 and a recent update about ActiveX KillBits. The ActiveX files are required by most web sites but you might want to try disabling the ActiveX in the Browser > Tools > Options > Addins just as a test to see whether it makes any difference.

    The other thing about using a web browser, for each tab/window you open, a new process begins but does not stop when you close that tab/window only whenthe browser is closed. If you open more than 15 tabbed windows in one session then you will have 15 processes of iexplirer.exe in the Task Manger, if one window is a bit slow in loading then it is probably a long running script or a big page full of images/rext/flash media that will more than likely gross about 25mb in volume.

    Basically, do your browsing but close the browser after every 15 tabbed windows have been exceeded, to ensure that your CPU and ram is not working over-time.

    if this is the case how do i get the computer to boot?
  3. If you could re-give the current details to all your hardware, make/model, including ram etc, it would help a bit in solving the issue.
    It might end up being a "stand-off" issue that has already been caused or it could be the ram all of the time either not being dual channel or the wrong model.
  4. ok so right now i have
    CPU: i5 2500k
    Heat sink: Coolermaster 212+ w/artic silver 5 thermal paste
    GPU: GTX 560 ti
    MOBO: MSIZ77A-G41 Z77
    PSU: Seasonic M12II 620W
    RAM: G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Dual Channel Kit Desktop Memory Model F3-10666CL9D-4GBNQ http://www.newegg.com/Product/Product.aspx?Item=N82E16820231190
    HDD: Western Digital WD Blue WD5000AAKX 500GB 7200 RPM 16MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive - OEM http://www.newegg.com/Product/Product.aspx?Item=N82E16822136769
    SSD: Chronos SATA III 120 gb MKNSSDCR
    also i never used Internet explorer, mainly firefox/opera
    but i have used memory demanding programs like after effects, photoshop, 3d models/animation, gaming, etc.
  5. The cabling is rather vague but it might be that you got them mixed up -

    The cable marked 6P/8P is not a 12v motherboard connector, it is for the video card.

    http://www.powerhousepc.com.au/index.php?productID=854
  6. I think it was actually mixed up but when i changed it, it had the same result turning on and off repeatedly with no bios or anything coming up on screen
  7. You have to make sure what cabling you use, it should click porperly and evenly onto the connector.
    The video card should also have its proper cabling.
    Re-check all your cabling and that they do click-fit properly.

    You might have reset the bios inadvertently or on purpose, the default for video out is onboard vga, change the cable to that port for the monitor.
  8. well i rechecked all by cables and tried the on board vga port and still nothing showed up
    should i just buy some ram to test? if not it is probably the motherboard or the cpu?
  9. Not real sure what to do next so the best thing is to bread-board the system (outside the case) and see if the rig powers up.
  10. would doing that really make a difference?
  11. In my book, bread-boarding is a last resort but only because it's a pain in the "recycle bin" to do it. :(

    If the system works fine outside of the case then there is something on the base-plate (where the motherboard fits to) or some other part of the case that is affecting the circuit connections. Sometimes a standoff unused can be touching a circuit causing unwanted issues. Sometimes the standoffs might be too low, the video card front plate is touching the motherboard, the io shield for the back ports is not properly fitted and the motherboard is not porperly fitted to the i/o shield causing the usb ports to be slightly aback from their fitting and any usb connection cable is not being seated.
  12. ok what kind of surface should i place it on my desk has some room and its wood with a finish
    also how i had standoffs touching the motherboard before but now i removed them and also how i had the wrong cable in the 12v slot
    would resetting the bios or clearing the cmos (or whatever it is, removing the battery and putting it back in) change anything with that?
    and also does it matter what way my heatsink is facing (cooler master 212+)
  13. The fact that you had standoff issiues before and that you had placed the wrong cable into the 12v connector could actually cause the motherboard to short circuit so by bread-boarding and only using the minimal hardware you can rule out most things that might still be causing errors. If the motherboard no longer responds, the m/board light does not illiminate, then you could consider the motherboard as being "dead".

    Everything should be removed from the PC case and the case placed away from the motherboard.

    The bread-board is usually a timber board.

    The direction of the heatsink is not an issue unless someone else makes it one.
    There should not be any cables to any device that is stretched or is tight, a slack of about 0.05mm should be adhered to.
  14. ok i just bought some new ram from best buy
    and i tested my old system right before still had the repeating boot
    but once i put in the new ram
    computer started up had a bios and everything
    then i tried going to windows it was taking awhile
    the copy on my ssd wouldnt load
    and then when i put in my windows 7 disk
    the ssd wouldnt show up as an option (i thought it did at first and actually formatted my storage drive...since i was going to format the drive but it does show up in the bios)
    i installed windows 7 on my hdd and it worked fine but my ssd still wont show up
    im glad it acutally works now but i lost everything
    and my ssd wont work
    and also just booting up takes forever even on the hdd
    this is the ram i bought http://www.bestbuy.com/site/PNY+-+Optima+4GB+PC3-10666+DDR3+DIMM+Desktop+Memory/2327496.p;jsessionid=B4D993D1B192EAC14A54CFAD1E1F52D2.bbolsp-app02-115?id=1218532316525&skuId=2327496

    ok the default for the motherboard sata is ahcpi
    and when its on that the cd loads, and the hdd shows up but not the ssd
    i tired IDE mode and when that happens the cd doesnt even boot up or is stuck on starting windows. edit; it finally loaded, just took forever
    but in IDE mode it says cannot locate partition even for the hdd and the ssd doesnt even show up

    everything seems to be taking a long time
    do i need to configure the ram or something?
  15. When installing OS to the SSD, you have to disconnect other hdd's from the motherboard. You set the primary to cd/dvd drive so that boot goes to the install disk then you Full Format the SSD (not Quick format) and select EXFAT option rather than NTFS.

    Usually, a first build may take up to 3 days of testing before you even get to connect the hdd, as was back in the days of yore. More recently, it seems to only require up to 4 hours of pre-testing prior to install of the OS. I suppose it's the faster processors that makes things go much quicker, as well as better hardware.
  16. well i tried only the ssd and my primary is my cd/dvd drive
    and now no drives show up in the options
    is my ssd faulty (it worked before it was my os drive before)
    and whats a good recovery program because i had a lot of important stuff on my storage hard drive that i formatted or is it impossible considering i installed an os onto it
  17. If you have insatalled over the top of your files it is really rather difficult to retrieve lost files, only those that were not over-written could be recovered but might be corrupted or incomplete. The procedure may take many hours only to realise that the files are no longer usable for people other than forensic investigators...
