Stuttering in games and scratchy audio.

[dustynana]

Hey, i am getting an issue where for instance i'm playing Alan Wake or some DayZ and my frame rate would be running at about 50-61 and suddenly drop to about 15 fps and i would get a repetitive and scratchy audio. I usually fix this by restarting my desktop, but another half hour or so later it happens again. I recently upgraded my GPU to a GTX 660 but this didnt happen until about a month and a half after installing the card. I have been trying to fix it for a couple weeks, some say its audio drivers or overheating but i have tested with different drivers and my CPU/GPU never goes further than 65C, but that's with games like Battlefield 3 which don't have this problem as bad.

This is my build.

-An Asus P8h77-VLE motherboard
-I5 3570k CPU
-GTX 660 GPU
-Seagate 1tb HDD
-2x4gb ddr3 RAMM
-450watt PSU
This happens more with some games than others, it was awful with Alan wake...not as bad with others, has a problem with Napoleon Total War.

It actually also did this while watching videos on internet explorer but i don't have a problem with Chrome, this really confused me. I read something about it maybe being a power supply failure, i used one of those calculators and it said a 400watt psu is recommended.

This should be power supply problem mate. I've seen your specs and yes a 400W PSU COULD BE enough but it will surely overheat when playing demanding games like what you are playing. All things have certain tolerance and I think your PSU have reached the max tolerance it can handle. I suggest you get a 700-900w PSU not just for your current built but also for future upgrades like your GPU.

Thanks, i had a feeling it had something to do with the PSU. You know of any that would be effective...like a certain brand that isn't not to costly.
