Solve : Computer lags randomly for 1 Second?

1.	Solve : Computer lags randomly for 1 Second?
Answer» My computer screen freezes randomly meaning that it doesn't happen all the time. When it happens everything in my screen just stops for a 1 second and then it keeps going, this will happen about for 10 or 20 consecutive minutes before it stops. This happens randomly, it doesn't matter if I am playing games or using the browser because it even happens when the computer has no applications running, just scrolling the mouse around desktop it will freeze with no applications open which is weird. When I watch videos a weird robot/lagging noise starts when the computer freezes. I know I have no viruses because I scanned my computer many times and also I did the memtest to see if it was the ram but everything appeared to be okay. PLEASE HELP Specs: GTX 760 2GB Cooler Master 750 W Bronze H87-D3H Gigabyte Motherboard i5 4670 8GB Kingston Hyper X ram Windows 7 Professional 64 BitAre you overclocking any of this? I had a similar issue occuring with a gaming rig when it was overclocked. I brought my clock back to native clock of 2600Mhz and the problem went away. My system passed memtest86, was running within proper operating temps and was having same issues with a 195mhz overclock bringing the FSB to 215Mhz for DDR2 800Mhz RAM, because multiplier was locked at x13 on this CPU. The small gain at 2795Mhz from 2600Mhz wasnt worth the system acting up randomly like this so I went back to 200Mhz FSM memory setting bringing system back to 2600Mhz for the Athlon Quadcore. The video and audio lag sounded like Max Headroom, http://en.wikipedia.org/wiki/Max_Headroom_(character) or a sound from the Matrix movie with a strange tone for like 1 second. I don't do CPU nor GPU overclocking. Probably not driver related, but do you have latest hardware drivers installed?YES, I check for updates every week to be sure that all my programs run as RELIABLE as possible.I'd return the vid card for a replacement...Before doing that. I forgot to say that every time my computer starts lagging when I open task manager to check the CPU performance the percentage jump up and down really fast. When it starts lagging this is what I see in task manager 4 to 17 percent then it goes down to 2 and then JUMPS to 14 percent. The CPU perfomance just seems that its going crazy. I am kind of confused what to do now Did you establish that it does this is safe mode? What if you reduce the screen resolution? Are you running more than one anti-virus? I am Running Malwarebytes and Windows Security Essentials. Should I eliminate one?No...they are fine together...just don't run more than 1 scan of any protection app at a time.I really don't know what to do. Should I configure something or change any parts?? Is this a home-built computer? Yes? How long ago., Did it always do this?Did you try fail-safe BIOS settings? Do you have any parts from other PCs you own? Have you tried to contact the board maker to see if your serial # is among a set of known defects? I build this rig. Its all brand new and its about 2 months old. It never did this, this lag/freezing problem started about 1 or 2 weeks ago. I never tried fail-safe BIOS settings how do you do that and what does it do? Quote Before doing that.

I am kind of confused what to do now Last time I SAW a CPU acting like this and there were no malware, it was because the CPU was roasting hot and it was thermal throttling itself to try to stay cool. The computer was a core 2 QUAD and the thermal paste was dried up between the heatsink and the CPU surface. What is the CPU temp at when running a utility such as speedfan? Speedfan can also display other temps as well such as GPU and HDD etc. If your running too hot then its thermal throttling and causing the system to slow to cool itself, and this will cause CPU to look like a heartbeat of spikes as its processing and then holding itself back over and over again to avoid melt down. Your CPU frequency of operation may also be jumpy as it tries to slow the cores to cool them and reduce creation of heat.My computer seems to me that it's stable in temperature.

Did you establish that it does this is safe mode?
What if you reduce the screen resolution?
Are you running more than one anti-virus?

I am Running Malwarebytes and Windows Security Essentials. Should I eliminate one?No...they are fine together...just don't run more than 1 scan of any protection app at a time.I really don't know what to do. Should I configure something or change any parts?? Is this a home-built computer?

I build this rig. Its all brand new and its about 2 months old. It never did this, this lag/freezing problem started about 1 or 2 weeks ago. I never tried fail-safe BIOS settings how do you do that and what does it do? Quote
