Bios not displaying, what could the problem be?

Running an ASRock G41M-S3 motherboard with Intel Celeron D 2.8Ghz 336 Prescott CPU, and Apacer 2 x 4GB DDR3 1333 ram.

Seems like the monitor doesn't receive the signal from the motherboard + CPU, as no bios is displayed, and nothing comes on.

Tried it on different monitor with different cable, same thing happened. Don't have another graphics card, graphics is onboard.

If you have no other dedicated GPU to try it with, does the motherboard start up? Like; lights, and does it pass post and such? Just doesnt show it?

G41M-VS3 R2.0 is the only one listed on Asrock site
http://www.asrock.com/mb/Intel/G41M-VS3%20R2.0/?cat=Specifications


I just thought it was only Acer and HP recycling old motherboards by adding new bits but it seems Asrock is cost-cutting as well.

Until now, I've never heard of an LGA 775 supporting DDR3 and neither for DDR3 ram being 800mhz!
Supports DDR3 1333(OC)/1066/800

"Penryn Quad Core Yorkfield and Dual Core Wolfdale processors" but not your processor.

Otherwise if this is not your motherboard, could you give more details as to its model number?

Wouldnt the DDR3 RAM not slot correctly into the DDR2 slot if the OP tried doing this? Or has the OP actually checked to see if the RAM slotted...

They've just changed the slot. looking under the motherboard, you might see a set of holes unused.
LGA supporting DDR3?
Have you ever seen DDR3 800mhz ram? I can't find any in a search. Maybe it refers to single channel ram?

To OP -
Apart from all that, a no bios might infer a corrupted bios chip, you'd need to seek Asrock for a replacement bios chip.
Can you confirm that my version is the same as your version motherboard?

The slot is changed, meaning DDR2 RAM cant even fit into DDR3 slots; so that problem would be very, very apparent right away.

Lots of LGA sockets support DDR3.

I do not believe the OP mentioned using 800 MHz, I believe he was using Apacer 2x4GB 1333. If he mentioned it elsewhere, perhaps he meant 800 MHz per sine wave, meaning 1600 MHz at double data rate?

"Lots of LGA sockets support DDR3." - but doesn't that seem rather wierd for such an older socket type?
I only mentioned 800mhz because it is mentioned in the spec sheet, my mistake, there is DDR3 800mhz (it's the minimum), I got a bit carried away. I'm seem to be seeing lots of the older socket types now being sold as later model Windows 8 ready motherboards.

http://en.wikipedia.org/wiki/DDR3_SDRAM

There is a thread where acer had converted a laptop motherboard to a PC motherboard and the OP was asking as to how some feature in a laptop would have any relevance for his "PC" motherboard. I've lost the thread, hopefully he replies.

Again, apologies for any misconceptions.

LGA is the most recent Intel socket technology. I believe you mean LGA775 as an "old" socket. Oddly enough however, there are DDR3 supported LGA775 motherboards.

I did not see 800 MHz in the thread by the OP, so I can't comment much there.
