Computer os not responding

[Galdorf]

I have 2 machines in with same problem they both stop responding
i have done the following:
Full hard drive diagnostics smart and surface scan both passed.
Full external spyware/virus/rootkit scan found nothing.
Full sfc scan found nothing.
Full registry scan and repair.
No tasks are taking up cpu cycles when it happens cpu is idling at 0-3%
Checked temps all normal.
Passed diagnostic tests including ram.
Checked and removed all starting programs.
Tried system restore on both machines no effect.

Any ideas what is odd i click on any program icon no response i can open up control panel and anything in control panel without any lag?.
Also start bar works fine as well its really strange.

I see you state this: "Full hard drive diagnostics smart and surface scan both passed." But did you do a chkdsk? Also what about the video driver? I have had video drivers cause random lockups before. Although this doesn't sound like the issue since you can open certain things with no lag. So if you haven't yet do the chkdsk.

Clone hard drive to a new drive...see if it follows. I find, more often than not, occasional "hangs" like that are a drive that is beginning to fail. It won't fail any tests..you can throw diags at it all day long and it will appear to pass just fine. But clone to a fresh drive..run on that new drive...the hanging problem disappears.

I really don't put much faith in hard drive diag tests. They're so cheap (well..usually..except for the past couple-a-months with the Thai floods)....just toss in a new one and try it.

event logs, live cds?

I had one that was similar last week. it was permissions, things would only run as administrator with right click.
I had to reset with subinacl.

I wondered about that, but dismissed it since nothing malware related came up. Not that it couldn't be though.

+1 to event logs and chksdk

if you meant me adam, then my chkdsk, sfc and mbam were all clean.

 

[Galdorf]

Ran chkdsk on both both passed and had nothing to fix going to image and try new hard drives.

Are you a victim of the 'ol "replace desktop with screen-shot picture"?

Look at your desktop wallpaper. Also right-click the desktop and make sure your showing desktop icons.

I was talking about the permissions that you stated. I thought it might be a permissions issue, but since the OP said there were no signs of malware I dismissed the thought, but said it could still be possible like you pointed out.

To add to what these guys mentioned... Have you tried running in safe mode and see how it runs? I'm thinking a hard drive that has developed very slow sectors and is working towards bad sectors soon.

Wondering what hard drive diagnostics software you used in testing the hard drive. In my experience I have found out that most built in diagnostics tool shipped with some computers are unable to detect a failing hard drive except if the hard drive is completely dead.

I use hitachi drive fitness test. Very reliable. Does the computer start in safe mode? if yes it might be a software problem, if no, then it will be hardware problem, try image the drive to a new one as pointer out earlier by other poster.

Also not mentioned here, check for blown or bubbled CAPS...
Have had system hangs on this issue...

 

[PC-MOT]

Did you solve this issue?

The problem was the AV the machines are both brand one had panada the other avast after running Soluto the boot time on the av were 300+ seconds i removed the av's re-installed and that fixed the problem.

Odd though why it happened no idea why never had problems with them before.
There was only one av per machine i had 2 machines with same problem one had avast the other machine had panda just uninstalling them the re-installing fixed the problem prob was a miniport issue.

Yeah two antivirus programs at the same time is a no-no.....definite no-no. The real time file protection of each AV product will bog down the system, can cause frequent issues like lockups or blue screens, and can even step on each others toes and make one or both useless. When you say you removed both av's and reinstalled..hopefully you just installed one!

Such a rare thing to see though....although I did come across one last week..they had Eset NOD32 and Avast installed on a laptop. And yeah it was dog gone slow.

I have had similar issues with antivirus software. Check for any Miniport drivers relating to that. The system could waiting for those drivers.
