Damage done from Red Switch on Power Pack?

MrMacca · 15 Jan 2008 at 17:47

My parents have been tinkering with their PC due to a problem with the Monitor continously turning on and off. I didn't have time to check the monitor on my PC because before I was going to check the monitor my mum decided to flick the red switch on the back of the power pack, whilst it was switched on.

She didn't tell me this until I had asked what did she do to make the PC not power up.

What might she have caused by flicking this little red switch, which from the looks of it controls voltage or something.

What effect would this have on the PC?

Once i can get a little understanding into the damage that could have been caused I can then find a solution.

Thanks in Advance

i believe the switch on the back of the psu changes the voltage so she has probably blown a few components. Are you able to test mobo, ram, cpu, gfx in another pc?

Yeah, going to 1st test a new power pack on it 1st see if it boots up, if not then I'll have to just check each individual part on my PC.

Parents eh

depends. if the red switch was the on/off switch - wont have hurt anything
if it was a rail split/combine switch, as found on tagan 2 force psu's then you shouldnt have hurt anything - but all bets are off
if it was the 110/220v switch the best you can hope for is for the psu to have protection built in and have hsut off. next up: fuse blown, next up psu blown by double voltage - but pc saved by ovp, next up everything fried.

It'll be the 110/240V switch. I've had a friend do this before, and azsked me to fix it.. fortunately, swapping the psu out for a new one did the trick, nothing had burnt out. So fingers crossed!

As above, sounds like 110/240v switch, most cases result in just a dead psu, the rest kill the entire system.

99% the PC will be fine with a new PSU. Usually there is a protection fuse soldered to the board inside the PSU which a competent person can replace but since there is high votage in there best to just get a new one.

Sounds like you parents are paying so make sure it's a good one!
