|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.
