At a Total Loss, need help...Have MOBO LEDs, no fans, no power switch, no POST, nothing but ASUS Power On and TPU Switch light
Fair Warning....THIS IS A BEEYOTCH of a battle I've been fighting....:pt1cable: 

I've been struggling with this for a couple of weeks now and I'm finally done surfing for answers and ready to ask for help. I've been to several websites and the most recent "steps" I've followed are from this website (Steps to perform BEFORE posting about POST)

I have a home built PC that has been functioning just fine for the past year or so. Then, one day, I decided to MOVE the PC about 6 inches...it was sitting on concrete and stayed on concrete...so, should not have been static charge. However, I heard a pop and then smelled that wonderful burning smell. So, I eye-balled the motherboard to see if I could see anything fried...nothing. So, I skipped the difficult steps and just replaced the PSU; I wanted a more cable-friendly PSU anyway, perfect excuse. :D  I went from a CORSAIR TX Series CMPSU-750TX 750W ATX12V v2.3 SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Active PFC Compatible with New 4th Gen CPU Certified Haswell Ready to a CORSAIR 860W AX 80+ PLAT FULL-MOD. Then, I at least had the "Power On" light on my ASUS Z-97-PLUS mobo. But it still would not boot. I pulled the graphics card...no boot. I pulled the Firewire card I have...no boot. I pulled the memory sticks two by two...no boot. (By the way, the memory sticks are G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL9D-8GBRL) So, I figured it's either my two month old MOBO or my two month old CPU that I bought bundled with the MOBO (INTEL BOX INTEL CORE I5-4670K). So, again, instead of taking forever with the RMA, I went to my local retailer and bought an ASUS Z87-Pro. Reinstalled everything...no boot. With the pro, I still get the PowerOn light and I get a TPU Switch to light up. I've disconnected all fans in my LIAN LI Lancool PC-K63 Black Steel ATX Mid Tower Computer Case...no boot. I've disconnected all but the CPU fan...no boot. Now that I think about it, the only things I haven't done are disconnect all hard drives, I have 8 of them...3 SDD and 5 WD Caviar Blacks. AND, I have not tested the CPU...but I don't know HOW to test the CPU. When I bought the new Z97-Pro, I cleaned the thermal paste off the CPU with rubbing alcohol and reapplied with some diamond paste...per my local retailer's suggestion. I even unscrewed the panel that holds the power switch in place to see if I could detect any melting there....nothing.

I'm at my wit's end and I have no clue what more to try. Do I go buy another Intel Processor???!?! I COULD take it to the local retailer and let them charge me $135 per hour to figure out what it is. But damnit, I'm a computer nerd for a living...I SHOULD be able to figure this out...lol. I've damn near bought a new computer already....lol. ANY other suggestions would be greatly appreciated.

Please help. My wife can't see her family pictures :lol:  and I can't get to my Plex library :fou: ...I'm now using my ASUS laptop to store movies and use as a temporary Plex Media Server...lol :pfff: 

Thanks in advance...I hope one of the REAL gurus on here can help me figure this out. :??:

I feel for you, bro. Had a similar issue several years ago at my workplace. After almost 8 hours, I finally figured out that the culprit was the PSU, and to make things weirder the computer turned on only after I installed 2nd BRAND NEW CORSAIR CX 450W PSU. The other one was... dead, yeah, brand new :D  So, this stuff happens.

Before shelling out more money on another CPU, third PSU or even your third mobo (lol, don't do it just yet) I would first try something rather different. Try assembling the PC outside of the case and see can you get it running it. In some cases the culprit can also be... well, the case (no pun intended, lol).


I agree. Try to check any and all relevant parts with any spares you can find, maybe from friends. Goodness it must be bad :(  the only problem ive had was a bad gpu from ebay but this sounds worse :(

Main question: Do the fans still spin? if so, the mobo is fine and it is cpu or hard drive.
If the fans don't spin then the mobo is broken, as fans shouldn't need cpu or anything else input but power from the mobo


Fans are not spinning...what are the odds TWO ASUS MOBOs are bad? One is two months old and the second is brand new.

The one thing I wish I had done is connect the MOBO external to the case with only the minimals to see if worked....I didn't, I installed it in the case with everything. Silly me.
