Power surge on computer

[Harriet Titi]

Due to the power surge, my computers stopped (blew up)working as such i don't know what to do? i am requesting your help.

replace your PSU, and pray that your chipset didn't fry when it blew.

PSU is about 10-70£ depending on what type of PC you have, if you have more HDD's and a beefy graphics card or quadcore then your going to need something top end.

Hope that helps! :thumbsup:

In almost all cases, the PSU will shutdown or fry before anything gets to the motherboard and attached components.

If you are really lucky, you might have a reset switch on your PSU. Or, if you want to go through the effort, you can open the box and see if there are any internal fuses that could have blown but these would need to be unsoldered, find another, resolder, etc.

But those are exceptions to the usual case.

First you must establish what you have. Speculation (it could be this or might be that) tells you nothing useful. The foundation of any computer is its power supply 'system' - numerous components that can only be seen with a multimeter.

A 3.5 digit multimeter is a tool so 'complex' as to be sold where hammers are sold for about the same price. One sold in Wal-Mart is less than $18.

Use that meter to measure DC volts on the wires between power supply and motherboard. First push the red probe into a nylon connector where the purple wire enters. This number should be 5 volts and never less than 4.87. Report this and other numbers to that the few who actually know this stuff can reply.

Measure the green wire both before and when the power switch is pressed. Also measure the gray wire again before and when power switch is pressed.

Also useful are numbers on any one of orange, red, and yellow wires after power switch is pressed. I suspect those numbers will either be zero, or slightly rise to quickly fall back to zero. But even those responses are critically useful information.

Currently you have no idea why. Why is learned after taking these simple measurements. Overall objective is to establish what is good - without any doubt. Only then move on to other suspects.

Another suggested replacing the supply on wild speculation. Well, a power 'system' is more than a supply. Surges (especially if using a power strip protectors) can completely bypass the supply to harm other power 'system' components.

Best is to first learn what you have before replacing anything. Best is to post those numbers here so that those with superior knowledge can reply with something useful.

Alternative: take it to the shop, spend more money, and learn nothing.
