Built new gaming rig for PC... Was running all games and just plain running extremely well and quick.

For some reason since yesterday it's been running extremely laggy and slow... Almost as if it had a virus.
I scanned and nothing. So I checked the temps of all my hardware and perfectly normal... I checked background programs and CPU usage and found nothing stealing any memory. I have not installed anything new from before when it was running great till now except for windows updates? Could that possibly be the reason? Any more troubleshooting that can be done?
Please help just built this bad boy and he's giving me problems... Specs shouldn't be needed to answer this right?
