Built system with ASROCK 939SLI e-SATA board\

AMD 64 X2 3800+
2x 1024 MB corsair TwinX
Radeon X1900XT

It won't post at all. No beeps either. I tried swapping memory, an old PCI gfx card, removed all but cpu, even tried without cpu. Also tested with Zalman 400B PSU. Same result.

I read somewhere on newegg that there seems to be problems with Antec PSUs and ASrock motherboards. I haven't been able to confirm it however. Something about a missing -5V rail. Anyone can help with troubleshooting? Or maybe have some knowledge about this Antec problem?

In these situations it could be a dead board. It happens.

Do not listen to the reviews.

this is NOT an enthusiast prissy board. It is meant for 10 dollar psu's and 15 dollar cases. Asrock, while it might be a good board and a quirky feature board (and I own one), they do not have psu requirements that would cause your board to not even post.

you should return your board. However, I would suggest trying it with a crap psu, if that doesnt work, its dead.

Corsair memory has failed on me 3x in the past 1 1/2 years. 2x with me, 1x with my friend. And we purchased the "higher grade" stuff too!

Your system would beep without the proper memory or bad memory. I would suggest trying it with another cpu if possible. OF course, you might have a short in the board and it fries 2 cpus. DOH!

I'm sure you may have had a bad experience which happens with all companies. To extrapolate that into the nonsensical rant you just spewed is silly.

The ASRock board is a well built stable board that when paired with the right components is a fantastic ocer as well. Either in its stock form or oced it is on par, performance wise with the best boards out there.

As to using cheap components with ASRock boards, that comment shows a general ignorance of, well, everything. If you check my sig you'll see I'm using an ASRock Uli based board (939Dual) with anything but cheap components; everything is high end. In addition, my DC Opty is currently at 2.6Ghz with RAM at 260 [CAS 2.5] and my X1800 XL oced to XT speeds. I'll see if I can get 2.7Ghz (9x300) when I update the BIOS to 1.80 later today.

wouldn't be an issue with SATA drivers by chance?

Something to try is to reseat your CPU, ram, graphics card and all your power and other connectors. Do the fans and the power light turn on? If they do then it's almost certainly a bad motherboard and you'll need to RMA it. If your fans twitch or only turn on for a second then it could be an issue with the power supply. If there's no movement of the fans I would again point the problem to the motherboard. Problems with modern power supplies have nothing to do with the -5V line. It hasn't been a part of the ATX spec for years. It has do with motherboards delaying drawing from the 12V lines to power the processor and power supplies having a minimum load for the 12V line(s) and shutting off.

The memory is claimed to be fully tested unlike most other memory manufacturers who just sell memory and give warranties. Corsair did agree that the memor modules were defective..... er 3 of them.... That's not nonsensical. If you test ram and sell ram, the buyer should find no flaws because they already did. Obviously, those companies lie and do not test all of the ram modules. Crucial I do believe does test them. In the past, all of their ram purchased by my old college were 100% perfect, thats over a 500 modules over the course of 5 years that I was there.

Going back to his original problem, the board most likely is toast unless he didnt fully push in a power cable or bent something terribly. Asrock has the worst customer service possible, so I would just toss it in the garbage and call it a day if in fact it is toast.

I've found exactly the opposite with regard to ASRock support. Granted, it may have changed but back when I had my K8S8X they were extremely responsive. I was on the phone directly with the engineers in Taiwan and got them within 24 hours to update their BIOS microcode to use mobile processors (which they could have refused to do given it was a desktop board) and when there was an issue with the board they issued a BIOS addressing the issue within 48 hours. imo, there is no better support in the industry (with the caveat, as I said of not needing to use their support recently so it may have changed).

Thanks, with that information I tried to reseat everything, still no POST

Then I rebuilt the pc on another motherboard I borrowed. No problem, post the lot. Then rebuilt the pc on my new stuff that didnt work before. Works like a charm now.

I must have been hit with the nub stick, hard.

Now my new problem. Cant break my X1900XT out of 60hz mode in XP >.<

Glad to hear it worked out. Guess all that ASRock hate will have to take a back seat again
