I tried to upgrade from Geforce2 MX 100/200 to this XFX GeForce 6600 GT / 128MB DDR3 / AGP 8X / Dual DVI / HDTV (P450-8529). My system specs are:
Win xp P4 2.26GHz 1024MB DDR-SDRAM MoBo: Intel D845EBT AGP Version 2 4X Power supply: 300W (3.3V & 5.0V = 200W Max). I am running 2 HD's, a floppy, CD and DVD drive off this PS. I disconnected an auxiliary fan and connected the power to the card.
I did the uninstall of the old driver (44.03) but did not use a Driver Cleaner. I used the Control Panel Uninstall and allowed the reboot after the uninstall. What I got when I powered up was:
The User Log In screen was scrambled. I could detect (barely) the icons, but the screen was divided into four sectors with the tob and botton positioned at the center. Jibberish. Horizontal scramble.
No, they don't. You might download one driver installation utility for all GF cards under XP, but within the installation files are different driver files specific to every card (at the very least there's different ones for each generation of card.) There's a HUGE difference between his old GF2 MX and the 6600GT. To think they'd use the same driver is ludicrous.
Even if you're updating the drivers for the same card it's always best to uninstall the old version first. Especially if you've been trying out beta drivers.

All Nvidia Videocards run off the same driver. Since your upgrading from MX (Nvidia) to 6600GT (also Nvidia), all you had to do was update the driver. If you went from ATI to Nvidia, the perhaps you should remove the old drivers, but this is not the case for you. You made a simple job ... difficult!

After giving this some thought, it's possible that the PSU may be underpowered for this card. However, in saying that, it is only a 6600GT and I just did a quick check around the net and found that XFX recommend as a minimum for this card a 300W PSU.
So in theory at least, you should be OK. You do have a few items powered of that PSU so my recommendations in the long term are that you should upgrade to a larger more powerful unit. I personally like Enermax supplies. I have seen a number of Antec supplies give trouble or go bellyup in some way.
The problem you describe could be a number of things including the above but the first thing I would try to isolate is that you have removed any trace of the existing driver. 44.03 Detonators won't be compatible with a 6600GT so that may explain some of your issues. Try rebooting to a last known good config. and try to remove any trace of the exisitng driver. You may need to reinstall the GF2 just to get the system up and running in the short term. Make sure you have a new more up to date set of drivers on hand ready for installation if you can get it booted OK with the new 6600GT installed. Failing all that, maybe a reformat of your HDD and a fresh clean install of Win XP and newer up to date drivers is the answer. It's a proven solution finder if software and/or drivers are giving you problems. It is however, time consuming.
Any thought of getting a speed increase out of a higher powered PSU is utter nonsense. The only thing a higher powered PSU will give you is more stability and that will only be if your original PSU wasn't supplying enough clean juice to your system to begin with. Higher powered PSU's are required for more demanding hardware like the higher end Nvidia's 6800 and ATI X800 series video cards and the faster processors from Intel and AMD. They can also be of benefit if you want to overclock components as this requires more power to do successfully. So don't think by buying a new 450W PSU, your going to magically get an extra 10-20FPSs in your favourite games. It just won't happen.
I hope this is of some benefit to you.

My thought is that your problems are 100% related to a woefully inadequate power supply. Get a decent brand name (like Antec) 350W-450W unit. On a second note, you'll notice a massive speed difference when you do get a decent power supply, but your 6600GT is going to be held back a lot by that 2.26Ghz P4.
