So i'm having some problems with my computer and i'm starting to think a fried power supply might be the cause of it. I was hoping someone can give me an opinion based on the symptoms i'm going to lay out.
The computer i'm running right now is a desktop.. i built it up from scratch myself so i know a bit of the basics and know a bit about basic computer language etc.
I'm running windows xp pro with wireless connection.. my wireless has been really weak, my sisters laptop will sit right beside mine and pick up full signal while i only get 2 bars.. i have an average lower middle line wireless network card and shes running a prebuilt 1200 dollar hp laptop.. i'm guessing the wireless capability is probably similar so i was thinking the power supply might be realted. also my computer has been frequently not restarting when i click restart as well as sometimes just not turning on for a bit. The light in the back of the power supply will go in an out a bit. The whole computer just seems slow.
I'm running 2gs of Ram with average other hardware. About 4 months ago my computer was plugged into an outlet whos breaker blew 2 or 3 times so im thinking that may have also had an affect. its seems to have just went downhill from there. So anyways sorry for the long read but i just wanted to try to be as detailed as i could.
Any Opinion, Input or Other possible suggestions would be greatly appreciated.
Thanks,
Greg.

Instead of playing around if you suspect the power supply get a new one.

From what you have said I'd replace it just to be sure !

I concur there. A Faulty PSU can Fry Components in an Instant.

Actual Cost of a PSU is nothing to the Components it actually runs.

Also get a Bigger one at the same time and see the difference?

I would also suggest a Surge Protector. All Computers should have one.

Testing using that method. "static testing" [Not static electricity , static meaning with no load, or at a "idle"] is OK to verify that it actually comes on & to get a ballpark figure on the output.

The only way to verify that a power supply truly isn't faulty is to test it under a load.
The average home user doesn't have the proper setup to do that.

A PSU is kind of like a car engine in one aspect.
At an idle it can "purr like a kitten" but buck,snort,back fire,miss,bog down.& stall under a load [acceleration].
