Is My Motherboard Failing?

[jlewallen18]

Hey all, I have been having quite a few issues with my computer as of late. When I use my computer, all of my usb's will disable and then re-enable randomly throughout the day. (For example, I'd be listening to music, and then my external soundcard, mouse, and keyboard would all disable for..about 5 seconds). There has been 2 times where my USB's disable and I get a BSOD, "APC_INDEX_MISMATCH." and I have to restart my computer.

Also, my desktop will randomly glitch and go completely gray, and all of the desktop icons disappear for a brief moment, after a few seconds, things return back to normal.

I have already gone to power settings and changed USB sleep settings to "Disabled."

If this means anything, we've had about 5 power outages in the past few weeks which have shut off the computer while it was running. My computer IS surge protected though.

Specs:
Mobo: ASRock P67 Extreme4 Gen3
CPU: i7 Ivy Bridge @ 4.2 GHz
GPU: MSI Nvidia GTX 780
RAM: 8gb Ripjaws
HDD: WD 1TB
SSD: 1x250 GB Samsung @ 1x64 GB Corsair
PSU: 750 W Corsair


Thank you!

I have also tried updating my USB 3.0 drivers as well

I'd say check your PSU to make sure all rails (12V, 5V and 3.3V) are consistent. I believe the USB uses the 5V rails (I may be wrong on this) so if it fails or can't provide consistent power then you might experience connection problem. I'd say try a different PSU just for the heck of it. Otherwise, it may be the board itself.

Thank you for the response, sorry if this is a dumb question but, how do you check that these rails are consistent?

Also, if it means anything, my PSU does make a whistling type sound while gaming sometimes.

Unfortunately, surge protectors can only go to far to help, depending on how close the strike was.

I use CPUID's HWMONITOR to keep a look at my temps and voltages from time to time.

I went to my BIOS and nothing looks out of the ordinary to me, but here, have a look at my voltages:

12 V: +12.091 V
5 V: +5.016
3.30 V: +3.360

See anything that pops out as unusual?

It's when stressed that's what counts. You may want to be in Windows and running hardware monitoring program (can't think of any now, but there are many of them out) while your system is stressed (playing games, running a benchmark, etc...) and watch for voltage spikes. If nothing seems unusual, I'm afraid to give you the bad news, it may be your motherboard going bad.

I ran prime95 for about an hour, (I know it's supposed to be longer but I was making sure to pay careful attention to the voltages. Unfortunately I did not see any voltage spikes, so it is assumed to be the mobo then?

Yeap, it may be the board if you don't see any voltage spikes. Also, the whistling noise could be from motherboard's power delivery section, too, unless you hear that it's clearly from the PSU.

At this point, I'd say if you have a spare PSU, try it anyway, just to confirm whether it's the board or something else.

if your mother board is failing then check the motherboard processor ,heat sink fan and the SMPS is it working or not .if you processor gets heat up then use the heat sink paste .it gives cooling to processor.

"APC_INDEX_MISMATCH." is a device driver error...

You could roll back your system with system restore to a date before you started having problems or try reinstalling all your drivers. Looks like there were problems with the usb drivers on that board because they sure have a lot of beta drivers out for it....

I would try a roll back first go back a couple weeks before maybe Windows did an auto update and messed something up?
