ATI 5770 switch to 16 bit in windows 7

I had to switch to 16 bit in windows 7 because of the game freezes and lock-ups. I am using the new 10.1 drivers. Does anyone know why this is happening? It has done this in 64 bit and 32 bit versions of 7 and vista.

But all is well now setting the graphics to 16 bit, which is basic.
The games play ok with no crashes.
Let me know if you need more info.
 
Let me re-phrase the question. The computer locks up in 32 bit mode, with screen freeze ups in games and power dvd. Sometimes get blank screen with mouse and keyboard lights out. Only the reset button cures it. Why would switching the display mode to 16 bit cure the lock-ups? Why won't it work in 32 bit mode?
Motherboard Gigabyte ga-x38-dq6
Memeory Corsair 4 gig DDR 2
Bios F8
Video Gigabyte HD 5770
PS 750 TX Corsair
 
I tried an older driver and put it back in 32 bit mode and have not had any game crashes. But I did have one instance of the screen turning solid blue. I turned the power off and back on and the bios had reset it self back to defaults. I did notice that the speedfan sample shows 4.03 V for the +12V and -16.72 for -12V. I don't know if speedfan is telling me, my motherboard is bad? or what? But I have played hours worth of games with no crashes. We will see 🙂

Ignore those speedfan voltage readings. Run furmark to fully load your videocard and look for artifacts or instability, it could be going bad. Maybe the PSU but, well if its a Corsair 750TX I would trust it.
 
Furmark runs good, Both the power supply and video card are less than 2 months old. My original video card (Nvidia 8800 GT) started overheating, so I just replaced it with the ATI 5770. I am now using the drivers that came with it, they are from september 2009. I also re-flashed the bios to the original that came with the motherboard. Cleared CMOS and still got a solid blue screen after playing a few games. Could it be something with the areo peak in windows 7 that causes it?

i dont get it. how does a video card just "start overheating"?
 
The Nvidia would always run hot, it made the cpu hot too 140 F. Don't really know what was wrong with but its replaced with a ATI that runs cool CPU at 99 F stock cooling. I may have found the solution to my problem. I found that I had the main drive plugged into a slave sata port. I moved it to a master sata port and have not seen any crashes yet. I may be speaking too soon. I kind of think, this may be a BIOS problem. When I flashed it last, it defaulted to its original bios, so I just left it.
 
Problem Solved !! Plugging the main drive into a master SATA port fixed it. I didn't think SATA had a master/slave setup. But according to the motherboard manual, it does. My secondary drives had another operating system installed, so I guess the BIOS got confused. Maybe somebody can tell me more info about the master/slave thing using SATA because I really don't understand. Just Greatful it works now. Cheers!
