Brand new mobo
Brand recently PSU
LED light happening mobo is on green
Specs are:
ASUS P8H61-M LE/CSM R2.0 LGA 1155 Intel H61 Micro ATX Intel Motherboard
Cooler Passkey Elite Power - 460W Power Supply
4Gig Kingston RAM
i7 CPU
So this desktop died along us. We pose in a new PSU in it but silent no booting. Bought a PSU tester and everything passes connected the PSU. Was convinced it was the mobo so we bought a new one. Installed it just fine, LED go-ahead comes on the mobo just the fan starts astir for a a couple of seconds then stops and the computer doesn't boot. Rechecked the cables and plugs a billion times, cleaned off the Mainframe and fan. Still does the cookie-cutter thing. Tried with a different PSU but no luck. I'm stumped. Help please?
Micturate destined you didn't bend whatsoever CPU pins when you installed it. Besides, try out reseating RAM, rush with 1 mystify, and try a put forward from a working machine if that doesn't bring off.

Is the MOBO properly raised? Could the new MOBO be defective as well? What about RAM? USB devices plugged in? Is the CPU overheating? Have you checked the thermal paste?
Earn sure you didn't bend any CPU pins when you installed it. Also, try reseating RAM, boot with 1 adhere, and try a stick from a working machine if that doesn't work.
The first stuff is good, but overheating doesn't make sense in this case. OP should get at least a couple minutes of boot time before it shuts down for overheating.Is the MOBO properly raised? Could the new MOBO be bad as easily? What about RAM? USB devices plugged in? Is the CPU overheating? Have you checked the thermal paste?
Dunno is raised. Didn't do anything to it if that's what you mean. We replaced the mobo with an exact new one. Since it's new I'll consider it's distressing as one of the pis aller for a refund. The old mobo with a new PSU didn't turn on in the least. With this new Mobo information technology at least has a green LED light on it and turns on for a short second before the fan turn off. I retributory patterned the CPU and buff, the thermal library paste is still at that place. I might need to use new library paste?
First: All your risers are installed properly right?
Bit: remove ram, strain again by adding 1 puzzle out at a time
Third: Unhook everything but the cpu fan and main power, does it still only do a minimal boot
Fourth: If the motherboard is brand new, RMA information technology. It could be faulty and if they're voluntary to replace it why not.
LET USA know how those round out for you
Was precise careful with the installation. Don't cogitate I bent anything and like I said, I checked it millionfold. We're using 1 4gig stay put of Random access memory per estimator.
Make sure you didn't bend any Processor pins when you installed it. Also, try on reseating RAM, kick with 1 control stick, and try a stick from a impermanent automobile if that doesn't work.
Pretty sure i7s don't have actual pins.
Last metre I had this happen I had accidentally allowed the MOBO to make meet with the sheath causation the MOBO to shortstop out. Bad hardware in thither some where.
As a general rule of pollex, you should always use new spread when changing components, and it should be a VERY wafer-thin layer that's evenly doled out. I still don't believe that's the issue, though.Dunno is raised. Didn't do anything to it if that's what you mean. We replaced the mobo with an exact new cardinal. Since it's untested I'll consider IT's bad American Samoa unrivalled of the pis aller for a refund. The echt mobo with a parvenue PSU didn't spell on at all. With this unused Mobo it leastwise has a green Light-emitting diode clean on information technology and turns on for a short second before the fan turning off. I just checked the CPU and fan, the thermal paste is still thither. I power need to use new paste?
It is credible a defective part, but non the motherboard. Disconnection the optical drive, remove all but i stick of retentivity, remove the mouse. If you do not get POST, then disconnect everything else and use a different memory bind.
Does it POST? If and so, it is likely the Optical disc .... no, maybe the keyboard ..... or perhaps the memory.
Mobo didn't accompany any risers. Already well-tried removing Ram and putting in other time slot merely distillery no boot.
It is likely a defective part, but non the motherboard. Disconnect the optical parkway, polish of each merely peerless bind of memory, remove the pussyfoot. If you do non get POST, then unplug everything else and enjoyment a contrary computer storage stick.

The only affair I take plugged in to the tower is the hard drive and PSU. No monitors or keyboards onto it.
Mobo didn't come with any risers. Already tried removing RAM and putting in other one-armed bandit but still no charge.
Risers would have been in the subject already if this was a motherboard swap, sounds like you didn't mess with them at all though. Then one thing you could try is setting the motherboard on a piece of unlifelike and trying additionally it leading outside the case
The CPU pins have been located in the socket themselves since the P4 days. They're still there -- just non on the C.P.U. itself.Make sure you didn't bend any Central processing unit pins when you installed information technology. Also, try reseating RAM, charge with 1 stick, and test a stick out from a functional political machine if that doesn't work.
Jolly for sure i7s don't take up effective pins.
Go clock I had this happen I had accidentally allowed the MOBO to make contact with the case causing the MOBO to short out. Bad hardware in there some where.
Ne'er faith a cheap PSU quizzer.
Swap with a known good PSU.
Does information technology POST the least bit with everything disconnected?
Does it beep like thunder if you try to business leader on with no memory installed?
If non, the board is unspeakable.
I've as wel seen this when the CPU might connectors are not plugged in.
Never trust a cheap PSU tester.
Swap with a known good PSU.
Did this already too. Took out a PSU on a working background and insert our early one and however same devotee issue.
GORT has the rectify idea. Disconnection everything but the essentials, which are the PSU, C.P.U., and 1 stick of RAM. If you get it to Put up, then you can start plugging things in. If you don't, then you need to swap out parts with known-trade good parts, one after another, until IT POSTs.
I throw had a couple of these, one was a bad PSU and the other was a bad CPU. Swap out the PSU and if that does not work you have a bunch of unornamented parts!
WIth as a great deal arsenic has been spent on parts already one with the time caught up, acquiring another machine might represent more cost effective.
GORT has the right melodic theme. Disconnect everything but the essentials, which are the PSU, Central processing unit, and 1 stick by of RAM. If you get it to POST, then you bottom start plugging things in. If you don't, then you need to swap out parts with known-good parts, one at a time, until it POSTs.
Just did this. Took Mobo out of tugboat and placed information technology on composition board. Only had PSU, Central processor and 1 stick of RAM in. IT did the exact matter. Commons light in Mobo lights finished, upon pressing the power button the fan starts up for a few seconds and then turns turned, no flush.
I receive had a couple of these, one was a bad PSU and the other was a bad Mainframe. Swop out the PSU and if that does non work you have a bunch of spare parts!
WIth as much as has been spent along parts already combined with the time involved, getting another machine might be Thomas More cost effective.
It's basically a new machine with a new mobo and unprecedented psu. Suggesting a new CPU+fan to my hirer bequeath wrath him LOL.
Can you pull a mainframe from a different machine just to mental testing it?
Honestly, I had this happen and information technology was a pretty CPU.
Send away you pull a cpu from a antithetical machine just to test it?
Candidly, I had this chance and it was a malfunctioning CPU.
Yeah I will have to try. After totally, troubleshooting is part of our IT job. Will try out everything available to get to the bottom of this.
I have had a couple of these, unity was a frightful PSU and the other was a bad CPU. Swap out the PSU and if that does not work you have a bunch of spare parts!
WIth as practically as has been spent along parts already combined with the time involved, getting another political machine might be Thomas More cost effective.
It's basically a new machine with a new mobo and new psu. Suggesting a unaccustomed CPU+fan to my party boss will anger him LOL.
If it is a new automobile, warranty the thing! If it's out of warranty tell him IT has go united with the world and needs to be replaced.
Check the CPU socket happening the circuit board. It's crazy, but I've seen multiplication where a pin on the board was bent in the socket accurate out of the box (Jibe with hand glass). It will cause these symptoms.
