It has been some time since I've had to rely on this post.
But, after having thought the problem was resolved, I've discovered it to be only temporary. Whatever is going on has found it's way back to creating misery in my daily routine. My computer, in it's current state has been basically rendered useless.
Here are my symptoms ...
Computer will boot up into Windows 7, in most cases, fine in both regular and safe mode.
The time it takes for the computer to stablize to a point of using it (ie all the startup apps executed, internet connected etc) takes a longer than normal time, but bearable.
Once the computer stabilizes, use of the computer, whether idle or through the use of an application works OK.
Within 5 minutes, the computer becomes unstable.
The harddrive light, rather than it's normal flickering, pulses. Long periods of access (5-10 seconds), followed by a quick pause in activity. This repeats itself indefinitately.
Applications in use become unstable, "Not responding", spinning cursor. Periodically there will be a brief period of response, catching up on any mouse or key commands given previously, only to go unresponsive again. Sometimes, the application windows simply turn black.
Sometimes the Taskbar will disappear, turn black.
Launching any new application during this state takes forever to launch, if it launches at all.
Bringing up the task manager is sluggish, takes forever, and when it does show up, disabling processes and running applications too is super slow. Often times Task Manager will go "Not responding". Same thing bring up Control Panel to check hardware. Don't even think about trying to uninstall anything in this condition.
I have waited for over an hour to see the results, but this scenario continues until one of two things happens. A hard reset, or, although rare, a BSOD.
It is rare I get any errors. The only time I get errors seems to come from trying uninstallations etc. One that does pop up frequently is "Windows Explorer has stopped working". It takes a loooooong time for it to restart. I can't even say for certain if it does.
My unqualified opinion is that something is taxing the system preventing the efficient allocation of resources. I'm not sure if it's system resources, or harddrive related.
Things I have so far tried to do to isolate the cause.
- Virus and malware checks by two different virus scanners. Both turned up negative.
- Uninstalled antivirus (BitDefender) with no change.
- Tried a different antivirus (AVast). No change.
- Took out all known startup apps with the exception of the antirus to isolate any startup apps that may be causing problems.
- Uninstalled my backup software to isolate it as the cause
- have monitored "Autoruns64" to identify anything suspicious. Some concerning missing files, but not knowledgeable enough to consider therm culprits.
- monitored "ProcMon64" (process monitor), but again, limited knowledge doesn't help in identifying any culprits. Basically watching it to see what might be hopping all the resources, but finding nothing alarming.
- ran chkdsk as startup. It fixed a few errors, but no resolve
- uninstalled most recent Nvidia Driver, and running with barebones WIndows 7 default driver.
- various combinations of start/restart via Windows (when I can) from both regular and safe mode. (This problem exists in safe mode as well.)
So, here I am again, turning to those with far greater experience and familiarity than I to hopefully help me overcome this issue. Ideally with as little inconvenience as possible.
I'm sure I could repair my WIndows 7 installation as I had done originally. Not ideal, but an option that will result in the least recovery. Last time I did it though, I was annoyed (mildly when I considered my options) at having to go through the process of reinstalling all the updates, and having to reconfigure all my OS settings. It took a while to get things back to normal. Having done that though, I fear it's only a matter of time before something unknown that may still exist, corrupts it again. I will find myself enduring this on a monthly basis if I can't find out what is causing it.
The other option is start fresh. Reformat, reinstall. A great headache as we all know and a last resort I would think. I have other applications installed on a second drive, which I assume would also have to wiped of it's contents and uninstalled to maintain the connections between the two drives.
And all this ... only to fear that their is a hardware issue. Perhaps the hard drive is failing (however, not getting any physical indication like odd noises or anything), or some other sinister hardware. On that note, let me share that when I first posted this problem in July, I had gone through the process of removing pieces of hardware (graphics card, usb card, memory modules one by one) to see if perhaps I could isolate a fault with one of those. Everything appeared to work fine.
In advance, thank you for all those that have the inclination to help identify and fix this problem. I have had great experience here and I am confident that any suggestions, opinions are credible and based on solid knowledge and experience.
