I’m having an ongoing problem with frequent, short system “lags”. By this I mean my PC will momentarily freeze up for 2-10 seconds, and then unfreeze and continue as normal. This happens anywhere from once every 20-30 seconds to once every 5 minutes (although more frequent is the most common).


This all began a week ago. We had suffered a thunderstorm while I wasn’t home and lost power. My PC had been on at the time. It booted up fine, however.


The next day, though, when I attempted to boot it up, it got stuck on the initial BIOS screen for 15+ minutes. I had to hold in the power switch and try again. After a second failed boot, I turned it off, unplugged, and started testing things. I reseated all of the RAM and tried booting with each stick independently. I checked to make sure I had no blown capacitors on the mobo. All fans were working as normal (and I’d last blown it out maybe a week earlier).  After performing all of these checks, I tried one last time to boot it up and the computer booted fine.


However, since that time I’ve had these reoccurring lag problems. As I’m writing this, I’ve experienced maybe 6 “freezes” since the beginning of my post.


When the lag occurs, one or more windows will freeze and show “Not Responding” in the title bar. The mouse is still responsive (to movement – I can’t click anything), and audio doesn’t always cut out. I’ve seen the lag happen to my browser (Firefox, and also IE when I tested it), games & applications, desktop explorer, everything. It also occurs when I boot fresh and nothing is running.


So far I have done the following:

  1. Run Memtest86  for 4 passes, 0 errors.
  2. Run CHKDSK on all system drives, no errors.
  3. Run Memory Diagnostic Tool, no finds.
  4. Run System File Checker (SFC), it found a couple of things and fixed them (sorry, didn’t write down the file names). Rebooted, still lagged though.
  5. Run anti-virus (McAfee and Avast) and anti-malware scans (Spybot and MalWareBytes). Only hits were a handful of items in Spybot, but their removal had no effect.
  6. Began monitoring system temperatures for CPU, GPU, mobo, and case using CoreTemp and CPUID – everything is well within what Google tells me my particular hardware’s specs are.
  7. Updated my BIOS to their current version (Dell AwardBIOS 1.0.13).
  8. Updated my video drivers to their current version (NVIDIA GeForce GTX 560, driver version


I’m worried that one or both of my two HDDs are failing, but searching has shown me similar symptoms also caused by failing mobos and bad RAM.


I can provide a detailed Speccy list for my machine, but here’s the summary for now:
