My computer has been having this horrible slow down problem since the second month ive had it, it has been 2 and a half years now and the problem will not go away.
Mostly everyday my computer will slow way down to the point nothing will work. clicking icons, pressing buttons, ANYTHING will just simply not work. I get the spinning blue icon that shows my computer is thinking about it and over time everything will go bright white saying "Not - Responding" This happens to all of my programs including Windows explorer itself.
This happens only at random times, usualy when the computer has been on for hours.
Ive checked task manager to see what is eating up my CPU (because the small yellow blinking light on the PC case for the CPU is on solid light and no longer flashing) But all of the tasks are at a perfetly reasonable memory usage and the CPU says it is working at 15 - 25%. The CPU light sounds like it is doing some serious thinking or as if i was running a full system scan.....but i have done nothing!
Ive checked the temperatures of my PC and nothing is over heating. I open it up anyhow and clean any dust out that i find. Ive even unmounted the fan atop my CPU and cleaned out the dust in those hard to reach areas beneath the vent.
Ive scanned numerous times with the AV which never finds a problem. The registry has been scanned and any errors fixed but still no help.
Also ran diagnostics tests and even ran memtest on my computer and it hasn't found any hardware or memory issues.
The computer will never shutdown when it is slow like this so i am forced to a cold shut-down. I disconnect the power and drain any power that may be left inside. I wait a minutes and plug in the power and boot up my computer. And somehow it KNOWS to be slow!! I wait for a long start up, long log in, and a long wait for my account and the computer will still be just as slow as before!
Leaving my computer alone for about 2 - 3 hours and it usually clears back up and is fast once again like it is suppose to be >: O
Normally the computer is quite fast, besides the random slow downs that take hours to clear up.
If there is anything else you need to know about my system then let me know and ill post my specs.
