I'm new to the board, so hi all.
On to the good stuff, my cpu p4 2.0a 1 gig pc800 rambus, intel d850emv2 mobo, and a geforce 4600ti. I built this cpu about a year ago and also bought an OEM windows xp pro, i registered it and it has worked great until recently. I built another cpu and installed the same win xp copy (on accident meant to install a "free" version) i put in the cd-key i had registered with. I realized my mistake, and reinstalled it with the "free" version (which works problem free).
Ok so i go to turn on my original system, and windows load bar runs, log in screen comes up, LOCK UP... restart... repeat... I boot to safe mode, I start up in 640x480 4 bit color and it works fine. To my surpise I get a message that my windows XP oem needs to be registered, so i assume this was the problem.. ok i register again. Next i get a error message "system can't find NvCpl.dll" I know thats a nvidia file so i find the latest drivers and install them.... Restart, no more error message, but i can't change out of 640x480 4 bit color without the system locking up.... I turned down hardware acceleration all the way and i change to 1024x769 32bit color 85hz refresh, no problem. I've tried every single nvidia driver i can find, i've even used the original install cd and NOTHING WORKS with hardware acceleration on! I really don't want to restore windows if anyone has any suggestions I would be forever grateful.
