I have been getting random lag spikes on my computer that effects my internet, sound, mouse pointer speed, and keyboard. When i get the random lag spike everything gets really choppy and glitchy when it happens and it goes in and out.

I have tried the following:
- Erasing the data on both my hard drives and reformatting with a clean copy of windows 7.
- I got a new power supply, SSD, graphics card, added another fan, and RAM thinking that it might be a hardware problem but I still manage to get the random lag spikes. The only thing i have left to upgrade is the motherboard and the CPU which i might think is the problem?
- I downloaded Core Temp to see if my computer was over heating but that is not the case.
- I updated all my drivers.
- I minimized the processes in task manager and msconfig.

My specs:
Intel core i7 2600
MSI H61MU-E35
KINGSTON DDR3 8GB
NVIDIA GEFORCE GT 630

when the lag happens are you playing any games or are these happening when running dvd movies or videos saved on the hdd?

Since you have eliminated viruses by reformatting and doing a fresh install... I would ask that maybe you remove 1 of the ram modules and see if that stops the problem.
If not swap the one you took out with the one that's in the slot and see if that helps.
Another route is to just download memtest 86+ burn to disc or usb drive and boot with memtest and run to see if there are any memory errors.
You might have to go into bios and set your boot device manually or hold F8 during start up and select DVD or USB. Check you motherboard manual for instructions.
Hope this helps.

The answer may be simpler than that. Are you using an anti-virus that scans in the background? Some antiviruses will take a inordinately large amount of resources while scanning your hard drives and cause lag at inappropriate times. I’d check to make sure that your antivirus is scheduled at a time of minimum usage and then leave the computer on so that it can scan at that time (having it scheduled at 3AM does not good if the computer is off at 3AM).
In that situation the AV will wait until it has to scan and then do so whether you’re playing BF3 or not.

@atomicWAR my processor is under warranty for another 2 years.
@johnnyq1233 I removed one of the ram modules and I am still having the issue. I will down memtest 86+ and run it to see what happens
@groundrat I have AVG and i have the antivirus scan the computer when its starting up. I've actually had no anti-virus at one point and i still managed to have the same issue.
