Accidentally put MicroUSB port in front panel USB, PC won't start....

So last night, I was about to plug my phone into my PC to charge it overnight (PC is off, but USB is still powered), but I was noticing it wasn't plugging in. I turned on my flashlight really quickly, and noticed I was plugging in the MicroUSB port instead of the regular USB end. So I quickly turned it around and plugged it in properly. Then I noticed that it wasn't charging at all. Being really late and having to get up early, I didn't think anything of it, I just plugged it into a regular wall charger. (Normally I would do this, but the outlet is quite far from my bed, so I prefer to use my desktop's UBS ports). Now this morning I try to turn on my PC, and nothing happens.

I pulled out the power cord and flipped the PSU's switch, and held the power button. Plugged it in, flipped switch, nothing. I unplugged the USB headers (didn't think it'd fix it, but worth a try) in case I damaged a port and it was shorting or something. I removed the battery and put it in again, and nothing. Tried one stick of RAM at a time, and still nothing. I'm not sure what else I can do to try fix it.

Specs:
FX8350 @4GHz stock
Gigabyte 990FXA-UD3
8GB Kingston 1600MHz RAM (2x4GB)
XFX R9 280
EVGA 850W G2 80+ gold (overkill, I know)
CM Hyper 212 EVO
Phanteks Enthoo Pro
120GB Kingston V300 boot drive (~3 years old)
240GB Mushkin Chronos (~3 years old)
750GB Crucial MX300 (~2 months old)
3TB Seagate (~2 yrs old)
2x 500GB Seagate (~2 yrs old)

I have been having similar issues lately with my PC, where it would take a while to start, but usually just holding the power button for a few seconds would usually start it. I have had some issues with this mobo in the past (read about those here and here) but I managed to solve them. Very recently I had this issue, but I was able to fix the slow games aspect of it by moving files around and trimming, but I do notice sometimes that Windows is sluggish on startup.

So I'm wondering what's going on / broken inside my PC. My best guess is the motherboard, and given the other issues I've had with it, I wouldn't be too surprised. I was thinking of upgrading to a 6600k, but I got into a small car accident recently so I'd prefer to not have to spend anything (or as little as possible) on this. Or would that really just be my best option?

Any help with this would be extremely appreciated!

Thanks,


Michael
 
Normally I'd suspect a dying PSU. Not always starting. Starting up after a couple tries, as it warms up from the attempts. Corrupting BIOS. I only hesitate since you've been having other problems before this. Can you borrow a known good PSU to swap in and check?

Tried that, no luck.

The reason I was thinking it may have shorted is because I thought the two pins on the bottom to hold the cable inside a power may have touched two of the contacts and shorted it out.




I was thinking of this too, but it's a highly rated PSU, so I wasn't really expecting this to happen. I do have a spare PSU, so I'll try that after work and reply here with my findings.

Thanks!

So I played around with it, checked the PSU and it still turns on w/o the mobo, so that should be good. I took out all the drives and tried to turn on, and it does. I put the drives back in one by one and each time it would still turn on. When I got to the last one, it would still turn on. I turn it off and try again, and nothing. I take out 3 drives, and it works. Plug one in, works, another one, and works. Last one, doesn't work. So I unplug the second one and it works again. I played around with this for a bit, and it seems like it's an issue with the number of drives that are plugged in. Right now I have all of the drives plugged in, and it's turning on. However, if I wait ~20 seconds after it posts and press the power button once, it shuts off right away, meaning Windows didn't load... (don't have monitor hooked up to it).

Thinking it's a PSU issue, but not entirely sure... Any ideas?


**EDIT**

I hooked up the monitor and it was giving the unsuccessful boot screen, so I just pressed Enter and it booted up to Windows no problem. However, I'm not sure how long it'll take before I get this issue again...

For anyone else having this issue, I just unplugged the PSU from everything, and it seems to have fixed the issue. A friend of mine had thought that maybe it was an overloaded capacitor, and it just needed to drain...

Anyway, to the two guys who offered their input, thanks a lot! Glad I could finally get this resolved!
 
Glad you're up and running again, but hang on to that spare PSU. This kind of problem usually gets worse over time. It sort of sounds like the PSU is struggling to produce enough startup current, which would be weird for an 850 watt in that system. Then again, I did have a PSU with that type of problem. It ran fine, but didn't always start on the first attempt. Finally replaced it after having to use a hair dryer to warm up the circuits before power on.
