help!

[supernoob]

one day i pressed power switch on my desktop
it made a pop noise and nothing happened
no burn smell it just made a pop noise
btw i had a protector
i thought my power supply went out
so i bought new power supply, new motherboard, dvd burner and bad ass surge
protector
i bought new motherboard cuz my old motherboard chip fan went out
(it worked fine without chip fan so i didnt bother changing it at that time)
i put them together using my old parts, hope nothing is wrong with them
man~ i pressed power switch but nothing happened
onboard led is on but none of my fans is running

i tried unpluging all fans, floppy drive, cd-roms and hard drives
and samething happened
i know my hard drives are good cuz i tested
i dont think it's power supply or mobo
what cause the problem?
processor, memory, videocard
they all looks good
can broken processor cause same problem?
i cant test them at home

Try this first and let us know what happens. You must remove the motherboard from the case when doing this.

You have a bad power supply, bad motherboard, bad CPU, bad ram, or bad video card.

You can pull the video card and the ram and the board should still start up - if the speaker is hooked up it will give you multiple or steady beeps. If it still won't start you have a bad CPU, PSU, or motherboard.

You need to make sure all power connectors are connected. You have a 24 pin main and a 4 pin aux on the motherboard, and possibly a 6 pin PCI-E on the video card.

Pull the CPU and examine it carefully for burn marks and discoloration - especially the underside.

sorry to bother you again but i dont want to waste any more money on stuff i dont need
seems im gonna end up replacing every single parts for my desktop

i highly doubt that my psu or mobo is bad cuz they are new
and i dont think i broke them when i install
im not that noob ( actually i built 4-5 pc with no problem)
i know there is chance that my psu and mobo is still bad
lets just says my mobo and psu is good

will i be able to start without ram and videocard?
how can you tell the board is staring up?
is cpu fan running?
i dont have any speaker that i can connect to mobo (i never needed one)
can you hear beeping noises with bad cpu?

i was looking up beep code stuff online
and ended up ASUS troubleshooting pc page

http://support.asus.com/troubleshoot...Language=en-us

then went to Further trouble shooting actions

they say "Remove all expansion cards & devices except the mother board, monitor, video adapter, memory, PSU, CPU, CPU FAN, HDD/ODD and
Keyboard/Mouse."

this is different than what you saying that's why im confusing


btw i pull ram and videocard but same thing happen (onboard led is on , no cpu fan running)

i found old working mobo i tried using it and same thing happen

my cpu bad?
my cpu fan works fine i tested it

i found the way to test psu with itself but it's kinda risky
so im thinkin about buying psu tester (i found some nice one) and cpu
but i want to make sure my cpu is really bad
my old working mobo went bad? i dont know it worked ok last time i used it

i wish there are tester like psu tester for every parts for pc
they are many different slot like agp pci express) socket 939, am2
i cant test my part unless i buy another same one which i dont do
hard to test them
my cpu is look just fine
no bent pins nothing looks bad

Does your case have a speaker? I would hook that up and check for beep codes first.

Then, you have an old motherboard that worked, and now it won't boot up with the new CPU?

That sounds like the CPU itself is bad. You could be certain by taking the chip to a local computer store and asking if they can test it.

[chipdip]

That would make sense, the loud Pop when it started up was probably the CPU. Like Alaron said, take the chip to a computer store and have them test it.
