6600GT Creating Problems

[baja150]

System Summary:

MB: Soyo KT400 Dragon Platinum
CPU: XP3000+
Mem: 1GB Corsair XMS PC3200
GPU: AGP MSI 6600GT
PSU: Enermax 550 watt
OS: Windows XP Pro SP2

I replaced my old AIW8500 with a MSI 6600GT and now I have 2 problems.

1) I turn the computer on and the monitor doesn't receive an input. I have to power down and back up again 2-3 times and then magically the monitor will turn on. I have a CRT so I tried the VGA connection and the DVI connection with adapter and it does the same thing on both. (Are these called VGA and DVI plugs?) I do have power to the vid. card molex.

2) I don't know exactly how long it takes, but when the computer sits idle for a few hours it freezes up on the Windows screensaver forcing me to do a hard shutdown.

Used driver cleaner for all the ATI drivers before I installed the GF card. After installing the card and booting up I installed the drivers from the Nvidia site (66.93). I have all the latest drivers for my MB and all the latest windows updates.

Any help would be much appreciated. I love the card, but could do without the problems.

Anyone?

Your hardware is bad, or bad hardware combination... try swaping your stuff

Try bumping AGP voltage to 1.7 in your bios. Turn off fast writes.

I experiened the same issue with my 6600gts for the last 12 hours, ever since i went witha beta b ios on the mobo. I finally got up and running long enought to downlaod the previous bios and reflashed it. I am rock solid again.
