Hey all. Been searching for a fix for this for a few months. Decided to make an account to get help. I can't take this anymore.

When gaming, my games run very smoothly and go from 60 fps and then it drops down to like 10-14 FPS for about five seconds. This repeats every minute or so on a fixed schedule. I know this because I have a dual monitor setup. On my secondary monitor is a gpu monitor displaying temperature, fan speed and gpu load all on a graph. Also a CPU and ram usage monitor. The gpu load drops down from whatever it is at while gaming, to about 20 percent while it's lagging. I consider myself to be very proficient with computers. I first thought it was a power supply issue, my graphics card wasn't getting enough juice maybe. Well I replaced my 500w antec with a 1000w rosewill lightning series. This was happening on my evga gtx 550 ti. I was in need of an upgrade anyways so I now have a evga gtx 770. Major upgrade lol. Anyways much to my disappointment this lagging problem has occurred on two different power supplies and two different video cards, so I'm thinking it is either the ram, mobo, or hdd. I ran memtest86 and it returned no errors. Ran chkdsk /r defragmented, scanned with malewarebytes and updated bios and I don't want to sink unnecessary money into this build. My rig is as follows:

CPU: amd a10 5800k not overclocked
GPU: evga gtx 770 overclocked +42 MHz
Ram: 8g g.skill ripjaws x ddr3 1866
OS: windows 7 ultimate x64, up to date
Mobo: biostar amd a55md2 ver. 7
Psu: 1000w rosewill lightning
Case: rosewill something or other micro atx
Hdd: 500 gb not sure what brand, sata 7200 rpm

Thanks guys for looking
 
If a clean reinstallation of your drivers doesn't work then a reinstall of Windows would be your last resort

What is your CPU temp during this? (use core temp) it may have started throttling if it begins reaching its maximum operating temperature (and seeing that you experienced the slowdown with both your GPUs, an overheating CPU would be a possible problem)
