HELP! my computer wont turn on Tags: Power Supplies Light Computers Motherboards Components Last response: April 21, 2011 12:38 PM in Components Share kgh91go April 21, 2011 3:13:52 AM Last night i came home from work and tried to turn on my computer but when i pressed the power button nothing happened! i looked at the back of the pc and the psu light was on but the moment i pressed the power butto, the light went out. i went to HP's site to see what to do and i followed their steps and found out that when my motherboard is connected to the psu the psu light goes off, and when my motherboard is NOT connected the light stays on. HOWEVER the fan for my psu is not working when i have it disconnected from the motherboard so i am not sure as to if its the motherboard or my psu that has a problem. i dusted out my computer only about a month or two ago and my only guess is that either my motherboard or my psu has burnt out but im not sure as to which one is the burnt out hardware so PLEASE tech gurus, HELP ME D: if youre wondering how i wrote this post, i did it via my brother's laptop More about : computer wont turn Ubrales a c 90 ) Power supply a c 97 V Motherboard April 21, 2011 12:38:29 PM kgh91go said:HOWEVER the fan for my psu is not working when i have it disconnected from the motherboard so i am not sure as to if its the motherboard or my psu that has a problem. This tells me that the PSU is bad. Take the PSU out, and perform the 'paperclip' test. This will confirm this.
