Hi, the problem is that my PC wont turn on at all! I was playing on a game and then it suddenly went off! I tried pressing the power button but that did nothing! I have taken out the psu and that is fine (or seems to be), I bought a new motherboard and it still wont work! It isnt the hard disc so what could the problem be? Plz help, my buisness depends on it! Oh and the PC os 2 3/4 yrs old. thnx for any help! Michael

Hey! apparently it looks like you might need to by a new power supply, I experience this type of problem 2 or 3 a couple of times last month, and this type of problem is sometimes due because you have your computer directly connected to the current, so I recommend you to buy a current regulator and a new power supply that will solve you problem hopefully.

I also have experienced a power supply bust. First check if the fan inside the power supply still revolves when you turn it on. if it does'nt ,do this: If you have a knack to fix it yourself try opening the power supply, see if the fuse is burned. I fixed two power supplies that has these kind of problems, I soldered fuse replacements on both of them. If the fuse is still intact, look for anything that was burned. If it does try buying a new Power supply. I hope this helps...

Yeah, it sounds like a PSU problem.

These parts are not really meant for repair, so if you don't know what you're doing, don't even think about opening it up and tampering with the guts of it.

PSU's are dirt cheap, so you'll be better off buying a new one, rather than electrocuting yourself and burning the place down for the sake of 25

NOTE: a recent leagal case where a faulty PSU blew a PC and components, the provider of the PSU had to replace all the units effected.

thought this may make some of you happy and writting off to your PSU makers..

hey, how about checking out the obvious things first did you have anything else plugged into that socket in on the wall, if not check the fuse box for the socket in the wall. Aslo when you had the psu out did you see if it would start out of the case check the power cord and everything leading back to the computer.

If PSU worked outside of the case, then it could also be a short somewhere inside the case when its installed, unlikely but part of the process of elimination.

Ummm. yeah i kinda have a similar problem as we speak it happened this evening. i just built a computer with the asus a7n8x rev 2.0 nforce 2 ultra 400 retail package. The computer just suddenly turned off in the middle of a game. not processor because the heatsink and temp levels were normal during game play. BUT after it died it never revived again. don't know what happened... thought it was psu but haven't baught another one to check it. when i hit the ON button on the back i/0 switch the green light on the a7n8x turn on. but when i hit the power on button on the front of the case the cpu fan, case fan, and geforce fx5200 fan Flash on for lesst then a second and then its dead still. no hard drive power up, no floppy power up. nothing. nada. just dead. its kinda like that guys problem... Well being a tech for minor old systems its ONLY one of TWO possibilities. the psu or the mobo. i'm kinda p**sed because i just made the damn thing. there's a feature in the bios which leads me to believe its the mobo. the ..ac power down restart..option in the bios.... i enabled it before this happened. but i didn't see a fix when i tried to drain the power and clear the cmos... it could be bad psu which isn't supplying enough current..hence the*ac powerdown restart* option. but i need more possibilities and test strategies.

oh just to let u guys know.... u don't need a cpu or ram even to see if ur psu and mobo TURN ON (everything will POWER UP). which means it'll just turn on and stay that way with nothing happening but at least u know the mobo and psu work. I tried this test on my psu and mobo. when i was first making it the test worked fine. BUT it wont even power up so i'm guessing its the mobo or psu but i still need suggestions.. keep in mind that mine and his problem are VERY similar. Oh yeah. hey michal B. with experience i'd definately say its ur psu so just get a new one with enough wattage to support ur mobo/processor requirements. technically i AM going out on a limb here BUT if there was a little money to spend on a test it would be a whole lot cheaper then spending money on a whole new motherboard and sytem components. its only like $25-50 for a new psu with enough wattage for for the future p5. so do'nt sweat it that bad. if that doesn't work then its the plug socket u plugged it into. like he said above there.

________________________________________

the DIRECT Current issue can cause problems especially if ur house has age old wireing.. no joke it burned out a mobo/and processor of mine before...but yea get a surge protector, a good power supply is supposed to contain its own voltage regulator so u don't burn out ur mobo/cpu...well the really old psu used to have this. almost like its own surge protector...but anyway get a surge protector. but if u guys got some suggestions and info for My problem also i'd like to hear it. i never reject a fellow tech's info...

respect to all u guys out there who actually took the time to learn all this stuff. with anger. low cash and determination....;)

check that also.

I have the same problem on pc. I have an antec 430 watt power supply and an Asus p4p800 delux mobo.

When I hit the power button, my power light flashes on for a brief second, but nothing else starts up, no fan, no hd, nothing.

I bought a brand new power supply and it didn't do a thing. I had a PC tech look at it and he suspects I need a new cmos chip.

I'm going to get a new mobo to see if that solves the problem.
