EMachine stopped displaying video (card not working, just mobo)
I have an eMachines T6528. It has 2.5 GB RAM, a 500w PSU, and a GeForce 7900GS (dual DVI, fan cooled - PCI-e). Just yesterday the monitor stopped receiving the video signal from the card. It is a Hanns-G 22" with a HDMI input (from the DVI on the card). it worked greta for a year and now it just stopped. I connected the monitors VGA input to the VGA on the PC mobo and that works (albeit less clear graphics). So the monitor is OK. I connected the PC to another 22" monitor and that did not work either. So I am assuming either the PCI-e port or the card is defective. The fans on the card are still working, but neither DVI port sends a signal.
When the card was in the PC (on startup) would beep once, then about 10 seconds would pass and it would beep one long and two short beeps. Kind of a 1-long pause-1short pause-1-1 beeps. I think it has a MSI MS-7207 mobo. From some error codes I have researched it might be a video issue. The weird thing is it is still making those same beeps with the 7900GT card removed. It will display in VGA from the mobo fine if the card is in or not.
Could the PCI-e port be dead? I have not tried to install the card into another PC yet. Any way to know if it is the mobo or the card? Just don't understand why I would still get those beeps even with the card removed.

I'm a bit confused....did you have all four of these in the ACER and are trying to put the 2x1GB into the Emachine? And that the 2x1 GB wouldn't work in the Emachine but they did in the ACER and that the 2x512 Acer cards worked in the emachine?
If that is what happened here is my best guess. The ACER MOBO will support 533/667/800 MHZ DDR2 RAM. The Emachine will only support 533 RAM. Iys possible the 2x1GB are either 667 or 800 MHZ and are not compatible with the Emachine but will work in the ACER.
i have a 7300gt nvidea in mine right now... ok, but not the best. runs dx9. and it helps to get the bios update from the emachines site to help with nvidea compatibility. To run most games now, you might need more ram, and for the price, a barebones with your old parts thrown in might be a better deal. The 7300gt is pretty cheap if you are just looking for a quick cheap upgrade for now. It works with the original 300 watt psu and works ok for me with 2.5 gb ram (2-4 gb extra ram realllly helps!). I think tiger direct has some nice deals on barebones and cards, it kinda changes daily.
OK when you increased the ram from 512 to 2G, your hands usually bump the video card and loosen the connection... Crack open your PC again and re seat the video card... This is all pertaining if you have a separate video card in that computer. Just unplug the video card and re snap it in.
Maybe you forgot to connect extra power to the graphics card? On that card I believe it is a PEG connector, some older cards used standard molex but this is a rather new card.
Also, some mainboards have extra power connectors for the pci bus to provide extra stability (mostly for SLI/Crossfire configs). Never hurts to check if this is the case and then plug in some more juice even if you are not using dual gpu's.
Good kuck and please come back with more questions if it didn't help-

I have this type of computer (just sitting around , not for my main computer) and I had a smilar problem. I took it to a guy I know (who owns a computer repiar shop) an he said the motherboards on this model go haywire about four years after initial power-up. On mine, it caused the power supply to blow-up (literally) and blew out most components. (Floppy drive, Sound card, USB ports, Keyboar/mouse plugs)
I really don't know if What he said is true, but I replaced the powersupply, and now it works fine.
