Lag spikes caused from PSU?

While playing games I get serious lag spikes every so often. Like every 5 minutes-1 minute. And when it occurs, apparently in HWmonitor, my GT and IA cores wattage drops from 20-30 to .05-2W. Meaning that when the FPS drops, the wattage drops. Could this be the reason for the lag spikes? Is my power supply broken? Any ideas?

Oh by the way-
Antec 750W Bronze Certified 80+ power Supply
Intel i5-4690 @ 3.5GHz
8 GB ram
Asus Z97-A Mobo
With or without GPU causes the lag spikes- EVGA GTX 770 w/ACX Cooler 2GB

I wouldn't think it would be the PSU in that instance, possibly, but I think the wattage drop is a result of the CPU and GPU being freed up of the load momentarily.

But during this drop, the game lag spikes. This lag spike is quite annoying, and has killed me quite a bit of times in a game.

Do you have any other programs running at the same time? Do the lag spikes happen when you aren't gaming? From what you wrote in the description, the lag spikes occur even when the GPU isn't plugged in?

AGH woops didn't mean to pick that as the solution. Meant to reply hahaha. I tried a complete reinstall of windows and disabling programs in msconfig. The lag spikes happen as in mouse lag while not gaming, but I changed the batteries on the mouse. The lag spikes that happen while gaming are much worse. The lag spikes happen with or without the GPU. I tried unplugging the gpu and testing it with the iGPU, and nothing changed.

Oops, fixed, I unselected the answer, not sure if it went through since it still shows solved on my end.

Hmm ok, I've actually had that problem myself on my computer at work. What I had happen was the mouse seemed to freeze, but the programs etc kept going fine, not like the whole computer froze for a second. Is that what is happening?

The solution for me was to set the bios back to default to clear all the tinkering I did and then set the ram configuration to XMP and I left it at the stock 1600mhz.

I would try returning the bios to default, change the settings you absolutely need (boot order, memory on xmp)
Long shot I know.

Hmm. How do I set the RAM Config to XMP? Also I have something else to say about the lag spikes. They now seem to happen on my laptop, and while I am at it, the same exact ones (Well atleast extremely similar) and they use to never happen on my laptop! That is weird. That means there is 3 possibilities, the network (Weird enough it is causing FPS spikes, not ping spikes. My ping is fine.), Steam/Skype (Doubt it, never happened before), or MSI Afterburner (Uninstalling now and testing.)
