Motherboard shutdown before windows

Last edited: Jul 2, I live in an oversea department of France. Are you sure I have a faulty power supply? I have had no problems with this unit till I changed the thermal paste.

The Bad: ATX connector had mega loose pin sockets below average 12V ripple suppression second tier capacitors 2 year warranty.

Checked the other 12v cable, without graphics card, without network card , hard drives , tried another power cord , still shutting down less than 1 second later. Not sure if the power supply or the motherboard , but it makes a low pitched noise before shutting down. Edit : The power supply vibrates making the noise. Pill Monster said:. Is it completely new build? Yeah the PSU is almost certain to blame, maybe it's shorted or dead who knows It should be replaced anyway, PSU is the cornerstone of any overclock.

And if the atx pins are loose you'll have all kinds of problems. Think Seems reasonably priced, my mate bought one for his Has 5yr warranty Joined Oct 12, Messages 10, 2. You didn't tighten the water block down to tight, did you? Do a re-check on those connections, too; and, others you may have bumped. If you took the CPU out of the socket If you can borrow another working PSU and test Also, makes sure all the screws, tools, etc. Joined Oct 6, Messages 5, 1.

There have been a handful of instances usually if I've been overclocking, where I would shut my machine off, unplug it, do something to it like reapply the TIM on my GPUs, then put it all back together again and turn it on and sometimes it would stay on and hang or do as you suggest and turn off instantly and not boot and after enough on and off cycles it sometimes would carp about overclock failure even though saving the same setting I already had would usually work fine.

So if you haven't reset your BIOS, I would do that now just so you can rule out instability due to your overclocks. How can I reset my motherboard? I'll also use another power supply to test if the system can boot. Everything was plugged in when testing.

Or did you try cleaning it while still installed? MrGenius said:. Not necessarily. But I wouldn't advise it. Motherboards have been the most common hardware cause in my personal experience of a computer restarting on shut down.

There are many motherboard components that can fail in order to cause this fault. It would be a very complex task to diagnose motherboard problems on a component level, and best left to a competent professional, which in most cases, is hardly worth it. One obvious sign that your motherboard is approaching the end of its life in general, is by finding capacitors that are bulged. As mentioned before, after the age of around 5 years, it is good practice to replace the power supply with a new one.

It will keep the rest of the components in your computer running happier, and promote the longevity of each and every one. To eliminate the RAM modules, pull one of them out at a time, and try a shutdown test with one module installed at a time. If you get the computer to shut down normally with one of the modules removed, find some replacement RAM for a permanent fix. I have personally encountered this problem many times.

Usually with older hardware , but software problems can also creep in at any time. I hope I have delivered enough information in order for you to fix this annoying problem for good.
