Solved Switch motherboard and hard drive

Acer / M1640
November 7, 2015 at 16:57:51
Specs: Linux , 2
I have an Acer PC with an Asus motherboard and hd (3). And a HP w2007v monitor. It runs win7 after a fashion but with some issues.

I also have an Acer motherboard and hard drive (8) from a previously fully operational Acer PC on Win7.

In theory they are both the same, except of course they aren't. I can install the hd (8) as a secondary device and read from it except the programme partition. If I try to run it first there is a run error which the windows error diagnostics can't fix.

If I use the Acer motherboard the PC starts up but the monitor doesn't react.

What do I need to change (on BIOS?) to allow the Acer mo therboard to run and start the HP monitor?

Thanks,
Andy

I don't know why you have (3) & (8) listed after the HDDs?

Windows installations are tied in with the hardware, primarily the motherboard. If you switch the HDD to a different board, the system very likely will NOT boot into Windows. That is neither a problem with the board or the HDD, it's that Windows detects the difference in hardware & says "what the eff"? At the very least, Windows will have to be repaired due to the different board configuration, but it's generally best to wipe the drive & do a clean install.

Please explain more clearly what you want to do & why. Do not connect any HDDs when testing the boards. Go with the bare minimum - one stick RAM, no drives, no case fans, no mouse (just a keyboard), & do a BIOS reset before plugging in the power cord.

Not sure whether you think the motherboard swap or the HD swap will clear the unspecified issues.

Monitors are usually no trouble. Are both motherboards using the same graphics? Maybe one is using on-board and the other a separate card, requiring an enable/disable in BIOS. Presumably there is only one monitor socket.

Always pop back and let us know the outcome - thanks

I am not clear on what you want to do here. It sounds like you want to remove the ASUS motherboard and install the Acer motherboard in the Acer Chassis with the idea that the ASUS motherboard is bad and preventing you from using your HP monitor. Is that correct?

It looks like your trying to connect a standard plug&play flatscreen.

Are you sure the monitor is functioning properly?

I don't believe BIOS cares about the monitor itself. Are you using a video card or the onboard video port? If your using a video card, please post the specs. If your using an onboard video port, you may have to see if BIOS has it enabled or disabled on the replacement Acer Motherboard.

Is this just a windows 7 machine, or are you dual booting Linux, because your specs say Linux but your write up says WIN 7?

And is the Acer chassis M1640 shown in your specs or something else?

Please post specs for both motherboards.

Thanks for your quick replies.

I am hoping to install the acer motherboard and hard drive and do away with the Asus motherboard.

However when I do that the HP monitor doesn't come to life.

The acer motherboard had a Gigabyte graphic card. I have since slotted this into the Asus MB and it fires up ok. I have also tried starting the acer MB without the graphics card but to no change. To sum up the Asus motherboard and HP monitor works with both the graphic card and with the default slot. The acer (preferred) motherboard appears to fire up but the monitor doesn't come alive.

Specs of Asus are P5KPL-AM EPU motherboard. Win7 32bit home premium SP1. Intel 2 core quad 2.40 ghz. 3GB ram.

Acer was Win7 64bit professional as I remember. 4GB ram. Intel chip but not sure what else I can read off the MB without a monitor to help.

I have reset the default BIOS through Asus and alternated the order for the ATA to load but still Acer and HP aren't a happy union.

The ASUS machine is currently turned on with the graphics card and the screen is on.

What more can I tell you?

Thanks,
Andy

About the Acer; you say it appears to fire up but nothing shows on the monitor. Is that when it was in its original case, before you may have switched anything? If the Acer computer wasn't working before all this switching started then it's, well, bad. When people say something like 'it appears to fire up' they usually mean they hear fans and drives spin up and see LEDs flash so when they see nothing on the monitor they think it's a video or monitor problem. But usually it's a motherboard or PSU problem.

If the problem started after you moved things around then something must have happened during the exchange or you didn't get it put together right.

There should be something written on the Acer motherboard near the expansion slots or the RAM slots to tell you what it is.

So neither the onboard video or the GPU work on the Acer motherboard. You say the GPU was originally paired with the Acer motherboard, otherwise I'd ask if you were sure about the slot type you've plugged it into.

If you could get into BIOS, I'd suggest posting the BIOS version it can sometimes help to identify the board.

You might try the CMOS reset jumper. If the BIOS had onboard video disabled and its not working with the GPU anymore, I don't know how else you would re-enable it unless its automatic? Or did you not remove the GPU card before trying the onboard port?

What happened to the previously operational Acer PC by the way, I mean how did it come to be parts? How long has it been shelved and was it protected from ESD?

More people answering now, thanks so much. An update today on the specs:

Hard drive (3) and (8) is just my reference to distinguish between the two. (3) being the Win7 Home Premium SP1 - partially working, and (8) my hard drive with my programs and files, inc Win7 Professional, etc.

The GPU is GV-N210SL-1GI (http://www.gigabyte.com/products/product-page.aspx?pid=3964)

Acer motherboard "G41T-AM Rev:1.2" (http://microdream.co.uk/pc-components/acer-g41t-am-pc-motherboard-intel-lga775-pcie-rev-1-2.html)
EDIT; Accurate photos of the mb on http://www.aliexpress.com/item/Free-shipping-G41T-AM-V-1-2-G41-Collection-X4500-graphics-chip-supports-dual-four-core/32248984226.html?

The Acer mb won't run the HP monitor (http://support.hp.com/us-en/document/c00916928)

I am starting to believe that it is a problem which has struck the mb, as until the unit was unassembled (my machine but not dismantled by me personally) the pc was fully functional. I also tried the Acer setup on another older monitor and this too was unresponsive. To clarify: from the Asus mb I switch-over the 14 strip power and the 4 strip power, the power pin switch, the S-ATA slot 1, HP monitor cable, Acer keyboard round socket, nothing else.

Q1./ I would like to use my Acer motherboard and my Harddrive (8) in the Acer M3640 case I have. By the way the M3640 case is second hand and has the Asus mb installed. My original question was why doesn't the monitor turn on.

Q2./ If I take the Acer motherboard to a tech guy, will they be able to isolate and repair the monitor marriage issues, or just tell me to buy new?

Q3./ If I ignore my Acer motherboard for now and want instead to use my Hard Drive as primary load with the existing Asus mb, how can I fix this issue:

"Windows failed to start. A recent hardware or software change might be the cause. If Windows files have been damaged or configured incorrectly, startup repair can help diagnose and fix the problem. If power was interrupted during startup chose restart Windows normally. Use the arrow keys to highlight your choice: Launch startup repair (recommended). or Start Windows normally."

The hd (8) doesn't have the drivers the Acer motherboard is using, but I can see the Asus program files while the Acer hard-drive is loaded (but the C drive 'program files' are restricted as "reserved" view).

I hope that helps all of you out there trying to help, thank you so much for guiding me through this.

There is a CPU on that Acer motherboard isn't there?

In response to Q1, I would say the Acer is dead, given that you have checked your connections and found them to be correct, have the minimal amount of required hardware attached to power up with minimal loading on your PSU, have tried the on-board port with no GPU card installed, have tried different monitors, and had tried a BIOS reset.

In response to Q2, I doubt it will be worth the cost to fix. I can not say the tech won't try to sell you a new one. A tech is not going to want to asses your problem without getting paid. If you really want to go that route, you could try calling around and trying to assess them over the phone. Try to briefly tell them the steps you have taken and make it clear you already have another motherboard available and don't want to purchase another. And ask, given all that you have told them, that if you bring it to them, what more are they going to be able to tell you. You don't want to pay, just to hear the same things again.

In response to Q3, I have no experience changing out one motherboard for another or in running a "windows repair". I believe Windows should be able to repair itself if you select that option. If windows does not have all the drivers, you should be able to get them afterwards from ASUS for your P5KPL-AM EPU. That is, so long as your operating system shows up in their drop down list for that board.

You will also need to visit the Gigabyte support site and look for drivers there to support your GPU.

Derek, ISAmad, Riider, daveincaps,

Thank you for your feedback and help. My perseverance was aided by your replies and I am very happy to say I am now sat looking at the same screen as I had been previously.

But mostly I would like to thank the manager of my local Maplin. I took the mb in to see if they could perform diagnostics, which they don't, but the manager was a bit of a pc techie and offered to have a quick test, and using parts from the store and his expert eye he touched the connections and with some magic the BIOS displayed on his screen. I would like to buy that man a beer, or two. I think the RAM had been knocked and even though I had removed them and put them back on more than one occasion, a sharp eye in a professional environment helped. So despite ISAmad suggesting, "A tech is not going to want to asses your problem without getting paid", just as you lot have helped, so did someone else.

Thank you all.
Andy

Sometimes RAM plays up if disturbed, due to oxide on the edge connectors. The trick is to clean the edge connectors with a soft pencil rubber then pop them in and out a few times to clear the sockets themselves. I've found it to be a surprisingly common cause for various issues, although it's hard to understand why it would have any bearing on the monitor not working.

Whatever, glad to hear it's fixed and thanks for popping back to let us know.
