jonathancullen89 Posted March 18, 2008 Report Posted March 18, 2008 alright so my brothers girlfriend has problems with her computer, she gave it to me to see if i could fix it. but the damn thing wont turn on, its got a new power supply so for sure that isnt it. i made sure everything is connected like it should be but when i push the power button i get nothing. any ideas on how to trouble shoot the problem? could it be the power button itself? if so how would i test that? thanks guys Quote 1992 cavalier build 1992 blazer s10 kenwood cd hifonics hfi2500d 6 soon to be 12 12" hifonics hfi12d4's shit ton-o-wire Blurred Vision Audio Team SMD feedback/refs. clicky!-
Unique Alternatives Posted March 18, 2008 Report Posted March 18, 2008 What about the power cord itself, idk why but mine went bad for some reason so i had to replace it. Quote
jonathancullen89 Posted March 18, 2008 Author Report Posted March 18, 2008 i guess i havent tried that, it is a brand new power cord so i doubt that is what it is, it has a new 500watt power supply in it.

maademperor Posted March 18, 2008 Report Posted March 18, 2008 how new is the power supply and what kind/wattage is it? was the power supply replaced because of this issue and now it still doesnt power on? are you sure it can support the computer? do you have a psu tester to verify? might be the mobo or even the button on the case. try shoring the pins on the motherboard that the power button goes to with a paper clip or something...

jonathancullen89 Posted March 18, 2008 Author Report Posted March 18, 2008 it is brand new, it was bought because of this problem. i cant for the life of me remember what brand it is.. i guess i could try that. i have a dmm, could i check for resistance on the power putton? if the button is out i shouldnt have any power, if it is in i should have continuity right?

maademperor Posted March 18, 2008 Report Posted March 18, 2008 (edited) sounds right to me... are you certain all fans are plugged in too (in particular if there is a fan on the cpu heatsink. many motherboards wont power on if that fan is not plugged in). You can also use this process to definitely determine the PSU is not at fault (cause then you might be able to return it and keep using the original): http://www.techpowerup.com/articles/other/22 if there is a grounding problem on the mobo it might have killed that psu before anything else happened.

jonathancullen89 Posted March 18, 2008 Author Report Posted March 18, 2008 alright ill check that out, thank you! Quote 1992 cavalier build 1992 blazer s10 kenwood cd hifonics hfi2500d 6 soon to be 12 12" hifonics hfi12d4's shit ton-o-wire Blurred Vision Audio Team SMD feedback/refs. clicky!-
AI James Posted March 18, 2008 Report Posted March 18, 2008 take a flat tip screwdriver tap it to the 2 jumpers if it doesnt come on then the MB is done Quote
EricM9104 Posted March 18, 2008 Report Posted March 18, 2008 Are the fans turning on but nothing shows up on the monitor? Try it with a different monitor. If that doesn't work, the mobo's more than likely dead. Quote 2015 Honda Civic LX 4dr | 110k miles | Stock 1996 GMC Yukon SLT 4dr 4wd | 260k miles | JVC Head-unit
jonathancullen89 Posted March 18, 2008 Author Report Posted March 18, 2008 no nothing comes on, no fans, no lights, nothing. there is no power going to anything. ill try the screw driver thing. i just connect the two power things right?
