Windows 7: System hangs when asking for Admin Priviledges

I have an annoying issue and it only happens about half the time my computer is turned on.



When I run a program in "admin mode", the screen goes black and hangs for about 5 seconds, the prompt comes up asking me to approve, I click yes, screen goes black for another 5 seconds then the program comes up. This also happens sometimes when I wake the computer from the screensaver. I also happens when I try to open task manager. With the specs of my computer, there's no reason this should be happening. The computer is only 2 months old.

I have run CHKDSK, did sfc /scannow, all are supposedly clean now. I checked my registry for errors, repaired those. Ran an AVG scan, also clean. My graphics drivers are up to date. All of my other drivers should be up to date as well. If I go into the device manager, there are no dreaded "!" icons next to any devices.

Any insight or help with this issue would be really helpful. It's a really annoying issue and I just want my computer to run like it should be.

When I run as administrator, I have a lag too. I never thought that it was a problem. Computers, take time to perform functions.

I'd say I agree if it didn't happen only half of the time. It's instant half the time and slow half the time. Something is up, but thanks for your thoughts

It does not happen all the time, because only some of the time the memory is needed for something else.
