Random Reboots / Failure to Boot

[burninatortech4]

I built my first computer a few months back and the experience has been good, on the whole.

Lately however, the computer has started to fail to boot at various times during the start up process. Some of the time I'll press the power button, windows will start to boot, and then halfway through this process the computer will shutoff. No BSOD or anything. Just completely die. In some cases it will stay shutoff and unresponsive, even when I press the power button. The only way I've found to break this 'lock' is the unplug the rear power cord and wait a few seconds. This breaks the lock up but the computer may or may not continue to fail to boot properly.

At first I thought this was a symptom of an unstable overclock but even returning to stock clocks does not fix this issue. I've run memtest and it's not the RAM either.

I want to stress that this doesn't happen all the time but it does happen enough for me to be concerned.

I suspect its my PSU but it's hard to believe a 5 month old PSU from a reputable brand could already be failing!

Here's my build

AMD Athlon 760k
Gigabyte F2A88XN-WIFI (Rev 3.0)
2 x 4gb AMD Radeon Memory 2133mhz
Samsung 840 Pro Series SSD 256gb
Gigabyte Radeon R7 260x (Rev. 2.0)
Corsair H80i
Fractal Design Node 304 Black
Silverstone STF65F-G 650W ATX
Benq RL2455HM

Yes even good brand name hardware mfrs. occasionally puts out a dud.

Do you have another known-working PSU you could swap in for testing?

Do you have a bootable CD with memtest86+ for thorough RAM testing or can you use a friend's PC to make one?

Did the problem start after changing to a greater overclock; if so it's possible the OC whacked the CPU and or motherboard?

I fixed the problem. There was some kind of short occurring somewhere in the setup. What tipped me off to this is that I could get the computer to restart from those lockups just by shaking the case a bit.

I took it completely apart and put it back together. That fixed the problem. :biggrin:

:biggrin: I was just going to state that it almost seemed like something shorting out...........

Glad you found it man. 😛
