Solved Not seeing installed graphics card

March 13, 2013 at 20:23:10
Specs: Windows Vista
Acer Aspire ASE380 (yeah, about 5-6 years old)
HT2000 motherboard, model: MCP61SM-AM Rev: 1.0A

Trying to disable on-board graphics and install new
EVGA GeForce 9800 GT.

Not seeing the damned thing at all.

Tried disabling onboard video and uninstalling driver. It just insists on re-installing it. No sign in the driver manager that the 9800 is even there, only the existing built-in video unit.

Power supply insufficient for 9800? It's the stock PS in the acer unit.

✔ Best Answer
Couple things to start with.

1 You can not have your monitor hooked up to your on-board video when you turn on the computer or the board will not use the PCIe card. It is going to be "ether or" not both.

2 You don't have the 6 pin PCIe power connected to your card.

3 The contacts of the card and/or the PCIe slot are dirty.

The 9800GT requires a minimum of 400W PSU. Your PSU is an "Industry Standard 300W" PSU. Even assuming it has the necessary power connector I doubt that it is up to the job. It's not just about power but also the amperage available at the various voltages.

I'm 99% sure that the PSU is the problem; you need a decent make (Corsair, for example) PSU with a rating of 450W or more.

400W requirement is for the whole system, the card alone use only 105W maximum (coming from +3.3v & +12v rails). U can run 9800GT with OEM 300W unit if u don't have many components (like extra hard drives, optical drives, cards etc)

I'm not quite sure what you are trying to say. Your first link states a minimum 400W PSU, your second is to a 430w PSU. I still doubt that a cheap 300W PSU is up to the job.

400w is the whole system but if u have low power components u can even run it on good 250w unit.
I only mentioned corsair unit if the OP decide to upgrade the power supply, it is cheap and reliable. I have seen cheapo & crap unit running 9800GT.

Okay, yes he should have a good power supply, but he would not be able to see the device manager to remove his onboard video if he had it hooked up properly. So I think he's trying to use two monitors.

}}} 2 You don't have the 6 pin PCIe power connected to your card.

DOH, yes, this is certainly relevant... LOLZ. First time using a PCIe GC, so that wasn't connected. I'd seen it and forgotten about it.

In my defense, the EVGA instruction manual is a useless generic thing consisting of 5 pages replicated in four languages that mentions "If your card has an external power supply"... I was thinking of an out-of-case add-on PS or something for some ridiculously high-end GC.

Still a major DOH! is called for. Don't worry, when I am working on computers, I keep my dribble cup securely fashioned.

However, related question, then:

If I hook it up and see if it will work, is there any likely chance it'll fry anything if it's inadequate to do the job, or will the whole thing just behave like it ought to and not work?

And even if it does work, is it likely to overheat and blow up everything?

I'm just trying to boost the power of this machine for the time being, the base unit is not my own and I already had that card for other purposes which are on hold at the moment... but I don't want to blow anything up.

Obviously, you're not liable for the advice being wrong, I'm just wondering if it's a bad idea and just give it up... quit now before I blow up anything, or "It'll just not work".

The main drains in this are the mobo, the OEM HD(Hitach, 300gb I think) and a WD 1Tb Caviar Black. There is a DVD player/burner but is isn't in use very much.

Glad we figured out that it was the aux power, but what power supply do you have? Did your power supply come with the 6 pin PCIe cable or are you using an adapter?

Yes some extremely weird things will start to happen when your power supply is under power, and yes sometimes you can actually damage things using the wrong power supply. So these are some things to keep in mind.

So you are installing this video card because you want your games to run better? or do you think that it will improve your overall computing experience? If you're not a gamer the only reason to upgrade the video card is if you have a high resolution monitor, or a multi monitor setup. Other reasons would be for the use of HDMI and such.
