Windows 7: Win7 freezes frequently - Even after reinstall

Hello all,



About a week ago my PC developed a problem where it would freeze every few minutes, however this isn't your typical freeze where the only remedy is a restart. I can still move the mouse, type, and interact with some applications I have open (In fact I've encountered this issue several times as I typed this up). When the issue occurs the task bar becomes unresponsive and I cannot use any shortcuts I have on the desktop. I can stop the freeze by pressing ctrl-alt-delete and opening the task manager, then I can interact with everything and task bar is no longer frozen.
Today I finished a custom install of Windows 7 Pro 64 bit, all of my drivers are installed and up to date and I'm still encountering this issue.
Please view my forum profile to view my system specs.

Any input is appreciated!
Thanks

I would Check your ram.
