New Graphics Card Problems

So I got this new graphics card for Christmas and it's causing some problems. It's a [BFG Tech] NVIDIA GeFORCE 7300 GT.

The Problem is after booting up it shows the login screen. When I log in the screen goes black and the monitor goes into standby. The only way to get a picture is to reboot, hold F8, and select either "Start using last know good configuration" or "start in safe mode".

Then I remembered I accidentally changed the resolution earlier. So I went into Safe Mode and fixed that. Still, same problem. I go back into Safe Mode, and the resolution reset it's self to the resolution that doesn't work.

When I start in the last good configuration it boots up and logs in with no problem. But when I try to open any program at all the computer restarts. Also it restarts it's self randomly during use.

I let my mom take a look and she discovered the drivers weren't installed. When we tried installing, it took to long, and the computer restarted it's self.

I followed the instructions for seating the card to the period. And my dad reseated it. I made sure it was plugged into the AGP slot (like instructions said) and it still wont work.

Also whenever I boot up I get a white loading bar at the bottom of my screen. This started a few weeks ago after my brother used the computer. Every time I try a virus scan my mom comes and closes the :censored:ing scanner. Any tips on stopping people from closing the scanner?


Can some of you smart people help me? I'm supposed to wait until I can take it to my uncle since he does programming but I don't want to wait a week. If it's a simple fix that even the dumbest person could do then I would like to do it. I could try at installing the drivers again if somebody can tell me how.

EDIT: Now I just get the below message.

Windows could not start due to missing file
<Windows root>\system 32\hal.dll
Please re-install and try again

Or something similar to that.
 
Uuh, if hal.dll is missing then you're pretty much screwed... it's the file that remembers all your system components. You'll have to reinstall windows.

I vaguely remember hearing at College you can recover that file... Something to do with using a Linux Live CD, but I wasn't there to witness it....

Unless someone else has another idea.
 
Take out your 7300 and use the video card that you had in before and try to boot Windows.
 
Assuming this is Windows XP, insert the disc and do an OS repair. That'll replace all system files (won't erase any of your own stuff).

I'm thinking that your power supply is now powerful enough or is failing, causing the restarts when it can't pump out the necessary juice for the Geforce. Any specs on that PSU?

Old one died

also got a brand new power supply, 350 watt

and unfortunately I don't have the disc for the operating system... mabey my uncle does
 
can't log in, not even in safe mode. make sure to read the EDIT in the first post

EDIT: I might try putting the old power supply back in. It was pretty reliable and is still in good shape.
 
Go into Safe Mode, install the nVidia drivers, and then restart.

Remove the old video card from the Device Manager, if it's still there.
He won't be able to do any of this with hal.dll missing.

Best bet is to get hold of an XP CD first.
