Hey guyz, i managed to unlock my sempron 140 but i've been having problems with it when i unlock it. Tried using several operating systems.

- Windows XP sp2 32 bit = hangs on welcome screen but when i uninstall the sound drivers, it doesn't hang.
- Windows Vista Sp1 32 bit = hangs when i run 3dmark or any 3d games, even in Facebook.
- Windows 7 32 bit = no longer hangs in facebook but still hangs when i play any games that has 3D.
- Windows 7 64 bit 7600 build = same with windows 7 32 bit.

These things happen everytime i unlock it. but m not having any problems running in a single core. I also tried playing with the voltages but it didnt do anything that would help. anyone here knows what the problem could be?
