Uninstall drivers question

Last response: in Graphics & Displays

The extent of my knowledge of computers will now be evident. I am going to install a new video card, and the instructions recommend uninstalling any current video drivers, install the board, hook up the power cords, and turn it back on. If I have unistalled the video drivers from the previous card, what is used to drive the monitor? ( I hope that makes some sense). Also, when hooking up the power cords, does it make any difference into which psu plugs they go into? There are two needed, so I'm guesing any two available should be ok. The plugs themselves are really tight fitting. Can I lubricate them with anything to ease them on?

If you aren't install any driver yet then windows use the default driver (screen looks weird and very LOW resolution).
You can't be wrong when inserting the power connector for your card.
Usually it need 6pin power connector, like this one:


What is your card?
If your card needs 2 6pin then you MUST connect both 6pin from PSU.

Installing a Galaxy GTS250.
The power cord has one 6 pin connector as you showed, going to the card, then split into 2, 4 pin connectors for the psu.

It is a Dell 375 watt. Not sure if there is a brand name or model # on it.

Yes, you can run a single GTS250 on that PSU. :)

Although it's probably not recommended, Get a nice branded 400w or better IMO.

Evidently I can't run it with the 375w psu. It runs for about 40 minutes, then the screen goes black. After restarting the computer it will then run for about 40 minutes abd go black again. Tech support claims I need a 450w psu.

the gts250 (9800gtx/+) was the fastest single chip card early/mid 2008, no way it would run on a 375w dell properly.

Then the question would be can I upgrade to a 450 - 500w psu? The computer is a Dell XPS400, 2.8 processor.
Also, if I am able to run for awhile before it cuts out, that would seem to tell me that I am getting enough power to the card. What is causing it to stop working? Overheating on the card, or cpu?

I suggest the power supply as being a problem. Now the issue with Dell is that their power supplies/motherboard combos in their systems are linked and proprietary so you can't always replace them with a new generic one. You should do a bit of research on compatability before replacing your power supply.

i believ his is an older xps 400 (http://www.dell.com/us/en/dfb/desktops/xps_400/pd.aspx?refid=xps_400&cs=28&s=dfb)

we all know the pentium D is a very good model for power efficiency.

I have both the 400 and the 410 (office pc's) and both come with the same exact PSU. If his PSU is the culprit he can opt for an EA430/EA500 and it will fit flush. Example :
