Windows 7 BAD sound stutter, High DPC Latency

[L3G1TN00BZ]

I recently installed the 64 bit version of windows 7 ultimate on my computer and it was a fresh install, i had to fresh install because i had 32 bit windows 7 but i wanted 64 bit because of its capabilities with my games so i installed ive started hearing these like glitch sounds when listening to music and doing something else (Playing games, surfing the web) so i looked on forums and what i got was a download to get this DPC latency checker so i did that and i noticed when the music glitched the bar shot up the program and a few people on youtube said to go to device manager and disable/re-enable some devices, i did that and it wasnt working... i have a hunch that it may be the graphics driver i installed for playing minecraft

I used to have a Dell E-510 (identical to the 5150). It was designed for XP. Vista runs OK, although with only 4 GB of RAM maximum the best OS is a 32 bit. The only real reason to install 64 bit is if you have more than 4GB of RAM. A 64 bit OS will address more than 4GB of RAM. The E510/5150 can only have 4GB of RAM maximum. The 64 bit even uses more of the available memory than a 32 bit, thus less is left for programs.

Best suggestion is to go back to the 32 bit OS.
