Hey everyone, sorry if this is the wrong section of the forum for this, feel free to move it if needed.

So my Windows 7 install is less than 2 months old, after I had a hard drive fail and had to reinstall. I have been having a problem which I have only noticed in the past 4-5 days. Every 5 minutes or so, the whole system will freeze for about half a second. I can easily notice this when listening to music, playing games or watching videos. Everything freezes, video and audio. I know this is not a big deal, and I’m not having a big problem with it, but I’m wondering if this could maybe get worse, or show that a piece of hardware is failing.
Anyone got any ideas?

Thanks!

Specs:
OS: Windows 7 Ultimate 64-bit
CPU: Pentium Dual-Core E5200 @ 2.50GHz
RAM: 4GB
GPU: nVidia GTX 470
Mobo: GIGABYTE GA-P43-ES3G
(Think that’s it, let me know if you need more info)
 
Got any anti-virus software? I think I read a thread in here a few days ago, someone was experiencing random freezes & slowdowns and it turned out to be a virus/malware/spyware.
 
Ok, so a couple of things came up in the scan, and have been cleaned out, that may have helped, no freezes yet. I have event viewer up, which section should i look in?

Thanks!

I know this is probably not the same issue but i was having this problem on a MacBook Pro Laptop running OS X. I found it was because i had an aftermarket drive installed it was parking the head trying to save power and causing system stalls like you describe. Not sure if it's related or not though.
 
So the scan came up with a couple of things, clean them out. Freezes still happen :/. Brief look at Event Viewer does not show anything, I don't think its a Hard Drive problem.

Besides the odd 100% spike, nothing is running that high. I'm gonna order in some compressed air and Arctic Silver 5 and redo the CPU.

Thanks!

I have had an idea. I was wondering if it could be a CPU stability issue? And that I should under clock it. The temps are never high (no higher that 45/50C). Any good CPU stability testing programs?

Thanks!

Edit: Also, its getting noticeably worse.

How often do the freezes occur? I know NOD32 scans your startup files after each update, so it could be this causing the freezes. I think my NOD32 updates 2-3 times a day, but I never notice it unless I catch the system tray icon animating.
 
It happens every 5 mins or so, I don't think it is NOD32. Gonna run memtest, will let you know what the results are.

Thanks!

Hey,

Just some updates, ran memtest on both my sticks of RAM, passed no problems. Also did a chkdsk on both HDDs, and that came up fine.

Thanks!

When the GPU is running at 100%, the temp shoots up to 90C (65C on idle). I know thats high, even on idle, but stability tests show that its stable.
Anyway of checking to see if any drivers are bad? Or should i just re-install everything?

Thanks
