PC restarting at random

Over the last couple of weeks I’ve been trying to find the problem on my other halfs PC, randomly restarting.

To cut a very long story short I ended up replacing every component that was in the tower case, mobo, cpu, RAM graphics card and power supply but I still had the problem, it was driving me mad >Sad how can you replace everything but still have the same problem?

Well yesterday I finally got to the bottom of it:

The reset switch on the case was dirty inside and was resetting the PC at random, so after all the work replacing components in the end it was a little bit of dirt behind a switch.

Never come across that problem before but when I next see a PC that has a restart problem the first thing I’m going to do is disconnect the reset button.  Grin

  I can remember replacing a reset switch in a case,  either recieved broken or I may have broken it.  Inexpensive normaly open switch, probably from Radio Shack.  Been looking at components for building, an urge I try to resist.

Well done for finding it. Amazing that a few pence switch can turn a box of electronics into an annoying heap of junk.

Who actually uses a reset switch? I use the main power on/off switch and the PSU switch when clocking/building. Leave it out.

Are you gonna use the spares for a 478 test rig?

I occasionally use the reset switch when my PC doesn't wake up from sleep mode - bios thing apparently, which they don't seem to want to fix...apart from that I never use it.

To stop it ever happening again I have disconnected the switch, im happy with that.

I’ve noticed on most PC’s these days if you hold the power switch in for about 5 seconds it does the same thing as the reset switch, can come in handy sometimes, if the reset button doesn’t work. I know what you mean Freddy about the PC not waking up, my Win7 rig does that sometimes too.

Sounds like an idea, the 478’s are getting old now and are more likely to fail, so a test rig could come in handy, most of the PC’s I have out there are 775, but there are still a couple of 478’s.

Up to now I’ve been using my other half’s PC as a test rig  Shocked

The bits will be here if either of us need them… and thanks Snowy.

They say things come in threes:

I had a call out to a PC that had the power button stuck in, (broken button number 2) I couldn’t repair it so I decided to put the guts into another second hand case, got it all put together, turned it off and on again a few times to test it and guess what?

The power button broke on that case too, (broken button number 3).

Odd isn’t it, 3 computer cases with broken buttons in a short space of time.

What a pain. You have to build machine twice for 1 payment.

Should be the last of broken buttons foe a while.
Now all you need is a decent case.  Shocked
