Solved

PC automatically turns off and doesn't boot up.

I don't know if it's a virus or hardware problem. it's not a heating problem since all fans are working and temps are good. It doesn't make the beep noise when i turn it on after.

This started happening recently for some reason and i don't know why it does it. Any help is appreciated.

  1. Quality or crappy PSU?

    Prob crappy, its G7 power extreme 580w,
    it's been good for prob bout 2 years, has it worn out?
  3. Do i have to buy a new psu?
    Can PSU be faulty even if everything starts up but then randomly shutdown for a bit and doesn't reboot.
  4. A PSU is the most important part of your system and it could cause really weird issues. On paper the specs don't look bad, but it definitely doesn't provide three 12V rails at 18A each (54A or 648W total). It only provides 396W (33A total) on three 12V rails. Consider it as a cheap 450W PSU.

    If your system has no GPU and a low power Intel CPU, then the PSU may not be the issue. It would be easier to answer your question if you told us what components are installed in your PC.

    Just watch one of the videos on youtube where the guy mentions that PSU is like a battery and loses power overtime. I did have this PSU for a long time so maybe needs replacing.
    My specs are:
    asus m5a78l-m/usb3
    amd 6300 fx with cooler master hyper evo 212 cooler.
    r7 265 gpu which i recently replaced
    an old 250 gb hard drive with 128 gb ssd which i got like in oct or november.
    4x2gb ram sticks. Motherboard has two dual way things so i got two of same in the same colour.
  6. The system doesn't draw that much power, but test with another better quality PSU.

    What kind of PSU is good with a reasonable price. From around 20 to 40 gbp?

    That's a really low end generic PSU that uses HEC as the OEM. It doesn't even have any PCIe power connectors.

  9. The XFX ProSeries 450W suggested above is a good unit.

    Ok thanks for the reply, going to order it and see if it fixes it. Do you personally think that could be causing a problem? The pc shutdowns randomly ranging from few seconds to 20min, everything is running (fans and hard drives) and i get no display, have to wait for a bit before it reboots and repeats the process.

    The Radeon R7 265 requires a 75-Watt 6-pin PCI Express supplementary power connector. What are you using to supply power to the graphics card?
  12. Second post from the OP has the crappy PSU make and model.
  13. What I mean is that are you using a dual 4-pin Molex peripheral to 6-pin PCIe adapter power cable?

    http://microdream.co.uk/pc-components/pc-components-power-supplies/g7-power-extreme-580w-atx-psu-power-supply.html#.VNfHtS62qqE He has no choice because that cheap PSU doesn't provide PEG connectors.That's why I recommend he gets a quality PSU.

    yh, had to order an adapter when i got the 265 since previous ones only required 4 pins.

    That's a warning sign that the PSU manufacturer doesn't think that the PSU's +12V rail capacity is sufficient to even have a PCIe power connector.

    It ran good without any problems when i installed it but past week, i started getting random shutdowns and no boot for awhile etc. and if that was the problem, the XFX ProSeries 450W would be good right?
  18. The XFX ProSeries 450W is more powerful than your current PSU.

    http://www.amazon.co.uk/HEC-Compucase-G7-Power-Extreme/dp/B005ERFYR8/ref=pd_sxp_f_pt

    That's low end HEC/Compucase. Specs are almost exactly like the HEC Z-power 550W. That model also has the same number of +12V rails and current ratings and also doesn't have any PCIe power connectors.

    It probably has worn out. Go with an XFX 550W or Seasonic 520W power supply and you should be set!

    The xfx 450 arriving tomorrow so we'll see the results tomorrow. Hopefully it'll be working good.
  22. At least you'll be able to connect your GPU without using adapters.

    A day later, the same thing is happening to my slow pc which i hooked up for a bit till my other one is good.
    I don't think its the PSU or anything affecting this. I think it could be one of the wires, keyboard or mice or the monitor.
    Monitor cant be making it shutdown or restart, if it was faulty, wont affect anything, just itself.
    Could be kb/mouse or the power wire.

    I switched PSU wire, took out wireless kb/mice usb and still restarted.
    Don't think there's a problem with the PC since my other one started to restart too today. Got a blue screen after i restart my slow pc, had to restart couple of times to load up the password screen.
  24. You mean that you replaced the power cord?

    Yh.
    Could the electric token metre affect the PC ?
    The electric went off and came back on so would that affect PSU by any chance since old one kept restarting after it happened.

    PC shows no display and doesn't boot up or doesnt turn off when i hold the power button. The slow one doesn't start up anymore when i power it.
  26. It could affect the PSU if you had a power surge. Please clarify which PC is the original one, which one is the slow one and which one is the old one as I'm totally confused by your last post.

    It sounds like it did affect the PC.
  28. yh prob, sorry couldn't update forum as i had no access to both of my pcs.
    I tried out the new PSU, didnt work.
    I took out gpu, still didn't work, took out all HDD cables and ram sticks, it instantly kept beeping which i didn't got before even though i took out ram sticks out before with old PSU. Now i got 2 sticks in with HDD cables in and it seemed to turn on.
    First time i turned on with two sticks and HDD cables in, got blue screen after i logged on and now it seems ok for now.
