I have just bought a ECS elitegroup RS 400A mainboard and an Intel Pentium D 930 3GHz dual core processor along with one GB of Ram. I have also got a PNY GEFORCE 7600 AGP graphics card. Appeared to have the NVIDIA technology but was considerably cheaper (and presumably not as good).I've upgraded my computer several times in the past but never had this problem. When I switch the computer on the power and HDD lights come on and I can hear the fan going but I have no picture on the screen and there are no further beeps or indication anything else is happening.I disconected the graphics card and plugged the monitor into the onboard graphics port and the same thing happened.Any one got any ideas?

You can try re-setting the bios, however more likely it could be that you have a DOA since not even the onboard gpu works (you have checked the bios upon bootup that the onboard gpu is active right? that is ofcourse if you even get to the bios), or that you might have made a short circuit when putting it into the case (you did use the spacers right? and connected ALL the cables.). Did you try the mobo with GPU before installing it into the case? If you did and it worked before you might be faced with an RMA.

First check all cables and jumpers.As a first step, remove the RAM modules and place only 1 in the primary slot...then try again. A bad DIMM will prevent you even from getting into the BIOS. Then swap to the other one. If it works with one and not the other, you have a bad DIMM. If neither works, try it again using the secondary slot. If still nogo, it's very unlikely to be a RAM problem. At that point, if you have another board that'll take that CPU available, I'd try to put it in there and at least get it to the BIOS to determine if the CPU is OK.Beyond that, looks like an RMA...both the CPU and the mobo, unles you can take it to the store and get them to bench a new mobo or CPU and show you they work.RegardsBob ScottATP IMEL Gulfstream II-III-IV-VSantiago de Chile

Thanks guys,It's starting to look like a DIMM prblem then. I've been back to the shop and replaced both the motherboard and the CPU and I've got the same fault.Is there a way of my computer shop testing the DIMM?

Test it by exclusion...have the shop put some other DIMM modules into the mobo, and if it boots, you have a pretty good idea where the problem was.RegardsBob ScottATP IMEL Gulfstream II-III-IV-VSantiago de Chile
