Answer» Hello everyone, this is kind of a last hope kind of post before I try to rma parts.
I built a "new" computer with mostly used parts but it's not turning on.
The parts are:
PSU: corsair cx500 (3 months old)
CPU: g1840 (new)
RAM: corsair vengeance 2x4gb (from friend, used)
mobo:asus z87-k (bought myself, worked for a while with an [email protected],2ghz)
Here the situation is this:
I press the power button, the psu fan starts spinning and the cpu fan also but very FAST, black screen/ no beeps
I also had some other parts that I TRIED:
CPU: i5-3570 (from friend, used)
mobo: Intel DZ77SL-50K (from store, used)
Here the situation is:
I press the power button, the psu fan starts spinning, the cpu fan makes an effort(for 2ms?) but doesn't spin.
The mobo has a red light flashing and my monitor has a black screen/no beeps.
Things I've tried:
Reset bios by switching the jumpers, removing cmos battery
Switch cpu fans
Using 1 ram module in the a2 SLOT (2nd from the cpu away)
I can't see bent pins in the socket so that should be ok
ThanksDo what you can to get the BIOS setup screen. That will confirm the motherboard is doing most or all of its job.
Try another VIDEO card.
Try another Power Supply.
Remove hard drive and DVD drive.
If the above does not help any:
Check the mobo documentation. Does it have a beeper?
If it has a beeper, try no RAM. Right, I said no ram. If the CPU can run, it will beep at you because there is no RAM. Bat if that does not force it to beep, the CPU is in la-la land and not doing anything meaningful.
It just may be the motherboard has died.

Thanks for the information
I'm not using a gpu, just trying the igpu for now
Tried another power supply, the i5 3570 fan now turns! still black screen though
wasn't testing with a hdd ANYWAY, just need to get that post
I tried the beeping method as both mobo's have a beeper, unfortunately the z87-k didn't beep although having a brand new cpu
The Intel DZ77SL-50K did beep
So now the end situation is...
z87-k, intel g1840 all fans turn(even without ram), connected with hdmi to mobo still blackscreen
Intel DZ77SL-50K,i5-3570 all fans turn(not without ram), still black screen
I've contacted the seller of the z87-k mobo as that still has one month of warranty.
I got the intel mobo + i5 3570 to POST!
The mobo wasn't that old so I was surprised that replacing the CMOS battery got me in recovery bios modus, then I had to change the CMOS jumper and I got into the regular bios.
Still not sure why the almost new corsair cx500 doesn't deliver enough power/broke to the 4 pin cpu
The asus z87-k is broken though, but I've sent it back for an rma.
