Can't replace video card Nvidia 8600GS on Acer Aspire M1610

May 5, 2012 at 05:59:46
Specs: Windows Vista, E4500 / 3Go
PC : Acer Aspire M1610
Vista 32 bitsFamily Premium
Processor Intel DualCore E4500
Video Nvidia 8600GS
Because the video card is Out of service, I tried to replace the initial Nvidia 8600GS with a new Nvidia Geforce GT440 (manufact. Sparkle).
The PC recognises correctly the card. I can install the driver.
But when it is installed, the PC freezes often (every minute) and crashes after about 10 min working.
After the driver is installed, in the task manager, in performances tab, the left core stays always at 100% of load.

I tried an other type of Nvidia card (Geforce GT520) with the same result.
I don't know how I can repair my PC ACER, because it seems not easy to find a compatible video card.
Thanks if somebody knows a compatible reference.

PSU is the original part from ACER : LITEON E5251-7 which is a 250W.

I already read a lot of comments about the PSU but one core of the processor (dual core E4500) is permanently used at 100% when I install the Nvidia driver for the new card. Not sure there is a relation with PSU. In this situation, the task manager shows a global load of the processor about 50%, which increases immediatly to a high value (80, 100%) when I launch an application (windows explorer, firefox ...)

With the previous card 8600GS, both core of the processor were used at a few %, even when I launched a application such as those indicated above.

You should remove the original SIS drivers for the integrated Mirage 3 graphics before installing the GT440 card. The 250W PSU is undersized. All references I could find for your card state you need a 300W min. PSU.

Doesn't sound like a PSU issue, since the GT520 (which uses less power than the original 8600) is also crashing.

Sounds more like a driver conflict, or possibly an issue with the older SiS PCIe controller. I had a similar problem with an AGP HD3650; it too burned all available CPU cycles after the driver was installed.

If you're using the latest driver, try installing an older driver and see what happens. You may have to use an older card with that motherboard.

I tried the first Nvidia driver for this model GT520 without change of the issue (from Nvidia site).

On a temporary HDD :

1- a new installation with windows SEVEN worked a little bit better : no crash, no visible freeze, but one core (CPU dual Core E4500) still loaded permanently around 80 - 90 %, for a overall load of the processor about 40 %, without any application open.
The only issue seemed to be the sound not really fluid. And ACER doesn't provide drivers for this PC for seven.
I didn't test with a heavy application, like games.
However I could burn a DVD with no increase of the overall CPU load.

2- A new installation of Vista gave the same issue (freeze and crash in 5-10 min)

3- I tried with a live Linux (Kororaa, from fedora) and in this case the Nvidia driver worked fine.

It seems to be a windows/driver conflict with this combination of hardware : motherboard ACER F672CR / video Geforce GT520 (or GT440).

I saw on internet a solution with a video card ATI HD5450. Will go back to the store to try an ATI card.
