Hey guys,

My PC stop booting up and I keep getting Post Code 75.
I looked it up and it states in the manual:
"Initialize Int-13 and prepare for IPL detection."

Which surfing the internet points me to the SATA controller (as it's an HDD detection step?)

The computer will not get pass this and I'm running out of ideas how to resolve it or if my board is just fried 🙁

I tried disconnecting all the drives from the SATA ports. System has been stable since I built in in April.

If anyone has any info I'd appreciate it.

ASRock X58 Extreme
Intel i7 920 (Stock) W/Corsair H50
G.Skill Black Pi DDR3 1600 3x2GB
2xSeagate 500GB 7200.12 SATA 3.0 HDDs
1xLite-On standard DVD-writer SATA
Radeon 5870 Eye6 (Giga version)
SB X-Fi Titanium
Corsair 750W PSU
Cooler Master Scout case
 
More info needed.
Any changes recently?
What happened when you disconnected the hard drives? Did you try to boot into bios?
Next step would be to try to isolate the problem to a specific attachment or setting.
BIOS reset? Careful.
Honestly, I don't know what a Post Code 75 is... anyone?

Edit: just did google... a lot of Code 75s.

Edit2: seems to maybe be a mobo issue.
Unplug all sata/ide, etc except memory and video and see if bios passes. If not, I would remove all memory but one module and try again. Did you reset bios yet?
You get the picture.

I said in my post what Code 75 was based on my manual and what I found based on my internet searches - seems its HDD related.

There are no hardware changes, system has been as listed since I built it in April. It ran fine until last night where it locked up.

Rebooting it didn't get my anyways. It has gone pass the Code 75 error twice the first time I got into Windows and used it as I normally would. The second time I was seeing if anything in my BIOS was different.

It won't let me get into the BIOS, it just locks up at Code 75. Even with all drives disconnected it just locks up.
 
Do you have a backup PSU?
I guess I'm just grabbin' for straws now.

Since you said stable since April I wouldn't guess a cpu issue.
Have you tried getting an AMD system? Just kidding.
 
No just one PSU at the moment.

I'm thinking from everything I've read my South bridge is failing.

I got a spare motherboard (MSI P45 Neo3) that I will be building up and installing my components into.

I'll be using pretty much all the same components except my processor, RAM, and motherboard.

If any issues persist I'll replace the PSU. If no issues it is one of the 3 above - my guess is motherboard.

So we can assume it ain't the hard drives. I would try a BIOS reset. Try at least to get into the bios. Have you ever done a bios reset? I'm not trying to talk down to you... just trying to be helpful.
Resets are done with a pin shunt. First unplug the PSU. Next press and hold the power button on the case for a couple seconds bleeding off the capacitors. Last, move the pin shunt to reset position for a few seconds then return it to where it was before you moved it before powering up. DANGER alert.

Yeah, CMOS has been cleared. I can't even get into BIOS to reset my options. Just keeps getting stuck on Splash SCreen.
 
Unplug and replug all the drives, Both SATA and power cables it could just be a loose cable. Try the easy stuff before going all out and installing a new mobo.

My Girl's comp was randomly locking up and giving HDD errors on boot but only every few days and i removed the HDD and tested the living crap out of it on my comp and it was fine. Then i thought it was the mobo and bought a new one. Still same problem. Tried my ram, same thing. After pulling my hair out for months i thought it might be the power cable since i was using a 4 pin molex to SATA converter cable as was a old PSU with no SATA. Bought new PSU, problem solved! Tested Molex 4 pin to SATA cable and found the 5v and 12v pins shorting out on the molex 4 pin end. Lesson learned, check the simple stuff first.
 
I have to build this comp for a friend anyways (a rental if you will.) I've been putting it off but I guess now is the best time to do so.

I just need a working PC for the moment. GF won't be letting me use hers for long. It's my day off so trying to trouble shoot my PC in the process.

Hopefully it is a simple thing. If I have to dismantle it completely to RMA the board I'll finish my case mod I started so long ago haha.
 
Well... if you've disconnected just about everything it still just may be the PSU. Most people don't have spares. Being the kind of guy that doesn't like to give up until the exact problem is identified I would try to borrow a PSU if I didn't have an extra.
Damn... you can't even enter the bios to check the voltage readings.
Odd that occasionally you could start Windows.

What PSU are you using? Oh, I see... Corsair 750W. Ok, if I can't nail it down I guess I would suspect the Asrock.
 
Okay, did all the nitty gritty and crap.

My computer:
ASRock X58 Extreme
2xSeagate 500GB 7200.12 (1xOS/1xBackup)
Radeon HD 5870 2GB
Intel Core i7 920
3x2GB G.Skill Pi DDR3 1600
Creative X-Fi Titanitum
Corsair 750W

Back-Up PC:
Gigabye (I thought it was an MSI) P45 DSEL
Intel E2160
Radeon HD 4830
Thermaltake 430W PSU
2x2GB DDR2 800 (not sure what brand.)

So, I wanted to rule out my PSU.
I hooked up the Corsair to the Back-UP PC and it powered up fine. Was in OS like usual. I know this back-up didn't pull as much watts as my other rig, so I started to toss things in.

I through in my Windows 7 Seagate drive it booted up fine, had to go through the hardware configuration stages (I used an old 160GB Maxtor for my OS install on the back up). So HDD isn't the issue.

I installed my Radeon 5870 2GB. That ran fine (however E2160 definitately bottlenecking its performance.)

I put in both HDDs it loaded up fine.


I used the 430W and HD 4830 on my ASrock board with the 160GB Maxtor Win 7 fresh install - still error 75.

I dug up a 40GB IDE HDD and not sure what was on it (OS or anything) and still code 75.

I'm confident enough to say something is wrong with the ASrock board itself. I contacted ASRock and am in the process of getting an RMA.

I switched the PC configuration back to the back-up since the case I was using is not suitable for an HD 5870's heat output.
