|"...my current card - Nvidia Geforce 6150 le "|
The term CARD is frequently mis-used. If a hardware device is built into the mboard, IT'S NOT A CARD! You have a Geforce 6150 LE video adapter or graphics adapter, or Windows calls it a Display adapter, but it is NOT A CARD unless it's on something that can physically be plugged into, and unplugged from, a slot in the mboard, inside the computer case.
The same goes for your networking adapter, sound adapter, USB controller adapter, etc. etc.
HP lists Vista (32 bit) and Vista 64 bit drivers and software for your s3100n, so there should be no problem at all with the mboard and it's built in graphics adapter working properly with Windows 7. There is no Windows 7 software listed, but Vista software will probably work fine.
Apparently the s3100n's mboard has maximum 2gb of ram that can be installed, so I assume you're using a 32 bit version of Windows 7. In that case you use the Vista (32 bit) software listed on the HP site.
Windows 7 doesn't necessarily have all the drivers needed for your system built into it.
Vista (32 bit) software and drivers
It appears the drivers for your nforce 430 main chipset are built into Vista (and Windows 7), but the graphics drivers probably are NOT. In that case, when Windows 7 Setup has finished, only default VGA drivers are loaded.
"I can only work in safe mode on this computer."
"...the default Display driver can work with Aero (I ranned the troubleshooter and it said Nvidia geforce 6150 le Wddm no issue present) and when I update the driver, it has 'issues'. It freezes either way (with 'compatible and non-compatible driver") at the desktop screen, now a little faster - hence why I can only work in safe mode - aeros doesn't load."
I have idea what Aero or Aeros software, or whatever, is.
Explain specifically what you're referring to.
It sounds like you have loaded the wrong graphics drivers, or something went wrong while installing the right graphics drivers.
Safe mode uses default VGA graphics drivers, not the specific video drivers you have loaded in normal mode. If you have a problem with the video drivers you have loaded, you may not be able to get the computer to boot normally, but it will boot into Safe mode okay.
However, Safe mode also does not load other things that are loaded when you boot normally.
Press F8 repeatedly while booting, don't hold down the key, and when the boot choices menu appears, choose:
Enable low-resolution video.........
That mode loads everything normally, except it uses default VGA graphics drivers, not the specific video drivers you have loaded in normal mode.
If that gets you to the desktop screen, your problem when you attempt to boot normally is caused by there being a problem with the specific video drivers you have loaded in normal mode.
Sometimes you cannot un-install drivers in Safe mode, but you always can in Enable low-resolution mode, if you can get into that mode.
If you DO get to the desktop screen when you choose Enable low-resolution video...

"....just CA basic internet security for spyware ..."
Anti-malware software often has one or more resident modules - a part or parts that run(s) all the time Windows is running, in the background, checking for suspicious activity.
That (those) resident module(s) are well known to sometimes interfere with software installing properly, and when it does (they do), you usually get no error messages indicating the software did not install properly. It is a very good idea to DISABLE the resident module(s) of anti-malware software from running BEFORE you install software yourself, by choosing to do that in the anti-malware software's configuration (or - to UN-INSTALL the anti-malware software, here, in Programs and Features, BEFORE you install software yourself). It's also a very good idea to do that before you install any major software, even if it's done automatically, e.g. a SP update to the operating system .
In Programs and Features....
Find the nVidia graphics drivers listing(s), and Un-install it (them).
The latest Windows 7 (probably the same as for Vista) 32 bit graphics drivers for 6150 LE:
Download that. Install that.
Boot normally. Your problem should be gone.
You MAY also need to un-install the Aero or Aeros whatever in Programs and Features, and install it again, when the anti-malware software's resident module(s) has (have) been disabled from running .
After you have finished installing the software, enable the resident module(s) in the anti-malware software.
