All sorts of custom-built computer issues

August 16, 2010 at 11:37:22
Specs: Windows 7 Ultimate, AMD Phenom X4/8GB RAM
OK, I am having a bunch of issues with my computer. It's a custom built. First, here are the specs:

-Gigabyte MA78GM-AS2H Micro ATX AMD Motherboard
-CPU: AMD Phenom X4
-RAM: Corsair XMS2-6400 8gb (2GBx4)
-Coolermaster CPU Cooler
-Corsair 800D Case
-Nexus RX-8500 PSU
-ATI Sapphire 4870 VGA Card
-ATI TV tuner card
-LG Blu-ray Drive
-Western Digital 2x1TB Green Drives
-Rosewill Wireless Network Card

Now for the issues, and there are a lot.

1) Only 2 of the 5 fans are hooked up. There aren't any more plug-ins for the fans but is there a way to plug-in the others? I read somewhere that I can plug directly into the PSU but I can't figure out how.

2) Sometimes the computer will boot up fine. Most of the time it says "Bootmgr Missing" or files missing or something along those lines. I will restart is several times and eventually it boots up fine. This computer is going to be used as an HTPC only so it will have numerous drives hooked up directly and via USB. When I plug-in the USB drives (11 of them), the computer starts up extremely slow (understandable). If I plug them in after it boots, it takes up to 20 minutes to recognize all the external drives. Most of the time when I boot up with the 4 external drives plugged in, it will not boot correctly, but sometimes it will. I have booted with just the main drive and it boots up normal more often but still not every time. I have Windows 7 Ultimate installed along with MyMovies for my movie integration into WMC. I also have some video game console emulators and that's about it. It usually cannot get through an entire movie in WMC without just restarting or going to a blue screen. Most of the time, it just freezes up in WMC before I can even get a movie playing (this happens even when I have only the internal drives hooked up).

I have less issues when I have the computer in my office upstairs (where I work on it) on a small monitor via VGA and then it almost never works when I bring it downstairs and hook it up to my 55" LED via HDMI. I'm not sure if it's possibly for it to be anything related to HDMI so I thought I'd mention.

Any help is greatly appreciated...

How many computers did you recently build? The link below indicates you recently built a different computer.

Explain this to us.

What type of External enclosures do you have USB powered or AC powered?

What is the exact model of your case? You don't need 5 fans.

Do/did you also have another post here recently? Someone had 5 internal and 11 external hard drives. Wondered if that was you.

You also had this thread.

I don't believe you posted your power supply.

My externals are AC powered. They are all WD or Seagate. My power supply is Nexus RX-8500 PSU

How are you connecting 11 external hard drives? Are you using a hub?

Verify that motherboard model. Google comes us empty.

This is the guy that refused to benchtest his hardware.


1) Assuming you mean case cooling fans, all you really need is one 120mm exhaust fan in the rear. If you feel you need/want more & don't have headers on the motherboard, you'll have to buy adapters to be able to connect the fans to any unused 4-pin molex plugs on the power supply.

2) Your Nexus power supply gets reasonable reviews but one minor "flaw" is that it has 4 separate +12v rails. That means that some thought has to go into the connections so that the load is evenly distributed across the rails. Depending on which Phenom X4 you have (hopefully a Phenom II X4?), it's probably either a 125W or 140W CPU. You video card isn't exactly a lightweight when it comes to power consumption either. Check your +12v distribution & adjust as necessary.

Why on earth do you need 11 external drives anyway? And why do they all have to be connected at the same time? As for the "Green" internal HDDs...they may save a little on the electric bill, but green = slow.

othehill - Yes, they are connected through a hub. That was the number I was given for my motherboard. The manual says:

Gigabyte S-Series Motherboards (GA-MA78GM-S2H). Thanks for your help!

jam - why do you have to come in here and attack me? I didn't build this computer, I never said I did. In fact, I said it was built BY someone else so it's not about me "refusing to bench test". I don't want to be rude but you just follow me around to attack me so I'm really not interested in your "help". And, by "help", I mean that you come in just to tear apart what I say, call me an idiot (not in so many words) and try to make me feel stupid. I need 11 external hard drives because I need 11 external hard drives, does it really matter or is it really any of your business? I wasn't aware that I had to divulge all of my personal information just to get some help.

You posted MA78GM-AS2H, now MA78GM-S2H. Even if you didn't build the computer bench testing becomes necessary when you can't get things to work as expected.

The fact that a different motherboard was replaced could indicate that a case standoff may be installed in the wrong place and is shorting out the board, as least intermittently. Not saying that is what is happening, but that can be eliminated if the board was bench tested.

Bench testing involves stripping the board down to the minimum hardware required for it to POST. One thing I noticed is that you have 2 sets of dual channel RAM. They may of may not be MATCHED sets though. If 8 GB of RAM was to be used then an 8 GB dual channel set should have been used. I suggest that at the very least, if you are not going to pull the board from the case you remove all but ONE stick of RAM, all the external USB drives, ATI Sapphire 4870 VGA Card, ATI TV tuner card, Rosewill Wireless Network Card.

Connect the monitor to the on board graphics and boot to the BIOS screens. Monitor the system temps and voltages.

Comments were made at about the north bridge on that board running extremely hot. Determine that the system temps are in the normal range. Wait at least 10 minutes in the BIOS before shutting down. Then install all the RAM and run a memory test on the RAM.

That is enough to keep you busy for a bit.

Get memtest at the link below. Run from a boot disk.

Thanks for the help but, again, I'm a novice. I don't know how to check the temperature of that other stuff, or what is normal for that matter. I have taken apart a computer before like that and was never able to get it fully working again. I really do appreciate the help but is this board for professional only? I really don't mean that to be rude, I just need to know so I can go elsewhere for help.

If you are not willing to do anything then take the computer to a shop.

If you find a competent shop they don't need our input.

Did you even bother to boot into the BIOS to have a look? Reading values in the BIOS screens shouldn't be beyond the ability of the average person. We know what is normal. All you need to do is post the numbers.

I suspect the RAM may be your problem. Novices are able to remove and replace RAM modules.

I guess there is nothing more I can do to help you.

I didn't say I wasn't willing to do anything but it appears that everyone on this site only speaks in computer language which is really only helpful to those that know a lot about computers. I know a decent amount of computers. I can pull out hard drives, RAM, install cards, etc but you guys don't even remotely speak on a novice level, even when requested. To me, it sounds like everyone just tries to show off the knowledge they know (a common thing amongst computer people) instead of actually helping anybody. Someone attacks me and I ask them not to and then you say you can't help me either. I simply asked how I take a computer's temperature or how I know what it is supposed to be but that wasn't answered, I simply got a "bring it to a computer shop".

Do you really think the "average person" knows how to boot into BIOS and read the "values"? If so, you guys are seriously detached from how the rest of the world is.You never asked me to post any of that information here, you just assumed I should not only know HOW to do but to have to foresight to actually do it. It is obvious that this site is only for computer professionals and anyone else coming in asking for simple help will be runoff like that morons that we are. I will use another site's services and I will be sure to post on my site & blog (about 2.3 million hits a month) about how this site assumes the entire world knows what a "Trusted Platform Module Header" is because if we don't, we are complete idiots! Goodbye, you don't see me again, go back to drinking your Monster Drinks and pretending the rest of the world doesn't exist.

I suggested you remove all but one stick of RAM and some add in cards. Used that language. What is so difficult about that.

Do you know how to use Google? POST can be found by using it.

We don't get paid to help folks here. At least they can be proactive about helping themselves.

You won a pig in a poke. Good luck to you.

but why should I have to google terminology when I came HERE for help? That makes no sense. On my site, it's not like I use terminology and have a footnote at the bottom saying "we are purposely using terminology that most people don't understand but you can go to this other website to find out what the hell we are talking about". Genius. I am being proactive about helping myself but if I wanted to google stuff, I'd just google it. I thought it would be easier to ask directly and get specified help but this is the same information I would find vaguely searching google so what's the point?

If you don't understand standard computer term like POST, BIOS, memory, cards, etc. How are we supposed to know that?

Insulting me isn't going to get your computer fixed.

I guess what you are saying is we need to dumb down our usual responses for you.

Normally, when someone doesn't understand something that was posted here they simply state that they didn't understand.

Why is it you can't do that?

Now, I am tiring of this back and forth dialog.

Do you or do you not want help? IF so, you need to follow instructions.

Response #9 was the first time you indicated you were a novice. Prior to that you supplied hardware information and made other comments indicating you at least knew something.

So, what parts of my response #8 needs clarification?

ok, I bench tested everything (as requested). Everything was working just fine, even with rebooting, etc and playing my movies on the computer. I moved the computer again, plugged in all the external hard drives and, again, everything was working just fine. It froze up at one point and I rebooted and it, again, went to BOOTMGR IS MISSING. I can't imagine this has anything to do with temperature...

As I stated above, I suspect the RAM may be the problem. Remove half the RAM taking care to use one of the matched sets. All numbers on the modules must be identical.

You have a enthusiast motherboard. As such, the default BIOS settings may be aggressive. One setting that you should look at is the RAM voltage. Although there are jedec standards for voltage, much of the "high performance" RAM uses higher than standard voltages. If the settings in the BIOS are not similar to what the RAM was designed to run with you can have problems.

I suggest you download a memory test utility. Burn it to CDR and run it from the boot. Get one at the link below.

Download Memtest86+ V4.10 Pre-compiled bootable

Unzip and burn to CDR. Then boot the computer to the CDR to run memtest86+.

OK, I just was researching your hardware. I believe the motherboard you have is not supposed to support a Phenom X4.

Who chose that replacement board?

August 19, 2010 at 07:42:30
the box says that is supports Phenom X4

After more research it appears that some versions support various versions of Phenom x4. No versions support Phenom II x4.

In order to put this issue aside I suggest you look at the morhterboard to read the version that shoud be printed on the circuit board material. Usually near the edges somewhere. Look for something like ver 1. Post back.

Below is a link to a chart of all the processors that will work in the various versions of that motherboard.

As jam pointed out above, some can pull a lot of current.
