(Bleepingcomputer has no proper forum for this question. Someone may need to move posting and responses.)

Computer which have been running, or ON for several hours have made strange behaviors. Maybe someone knows about these things and can tell why.

An old desktop computer was kept on for about 12 hours and suddenly, all the program icons looked wrong; they were the wrong icons for the programs, or several icons turned into all one kind.

Not so old laptop computer was kept on for a few hours, and then allowed to "sleep" overnight (meaning still turned on but in lower power state). When this computer was woken several hours later, a Cyberlink application/program was open and took over the whole screen; nobody ever intentionally opened this Cyberlink program, so it's running was a complete mystery. (Closing this program was no trouble).

A fairly new tower/desktop computer, after being ON for about 2 days, suddenly started playing a radio discussion broadcast. No applications were running based on inspecting listings in Ctrl+Alt+Del.

In all of the described three cases listed above, RESTARTING the computer stopped the problem. What makes these strange behaviors, and what does restarting do to stop those or bring them back to normal?

The proper forum would be the Operating System that machine is running under. You don't mention it for any of the computers.

That is the trouble with deciding which forum to post. Different events, different occasions, different operating systems. The Operating Systems did not matter.

The strange icons - in about 2004 or 2005. Windows 98SE.
The sudden running of Cyberlink - in about 2009. Windows Vista.
The strange radio discussion broadcast - just today. Windows 7.

In all of these events, the computers had been in operation, or in some ON state for several hours or longer. In all these events, restarting the computer eliminated the problem. These seem to all be the same kind of problem; three different versions of Windows.

Could it be in the Internet Connection or Router?

That seems to be a common thing?

What about the Internet Connection or the Router? This might maybe be relavent to the radio broadcast occurrance on the new computer(Windows 7) of today, but irrelavent to the other two described problems. Also, for todays problem, the computer was restarted to eliminate the problem; the router was not restarted, and the connections were not changed or checked - weren't necessary.

("Cyberlink" is the name of a program on that computer and has nothing to do with internet or web; also not a program I used or plan to use.)

Is everything working now.

Hard to comment on matters that occurred years ago and I've forgotten most of what I knew about Win98SE.

I would think that the Cyberlink program was probably PowerDVD; if it was ever a problem, it can be disabled in 'services'.

The recent problem with the radio broadcast may be due to files being left in your cache or your configuration of the Media Player, if you use it.

If you suspect malware you can avail yourself of the help available here:

@Post #1 "RESTARTING the computer stopped the problem. What makes these strange behaviors,

Difficult to give a definite answer. Isn't the first question from computer support: "have you turned it off and on again?"

Wonderful how many times this fixes the problem, but they can never explain why.

@ petewills

You are quite Right.

The OP certainly did not give many Details, nor said whether it was fixed now? Just made random things to confuse the Issue.

I picked out Internet Access/Router as a POSSIBLE cause for the joint Problems, then the OP just changed and was quite rude, so I never replied. Why should I?

One always wonders?

With regard to the old desktop that was on for 12 hours, that sounds a lot like a handle leak to me.

In Windows (indeed, in most current operating system paradigms) everything has one or more associated 'handles" which are references (called pointers) to where a particular resource is located in the system memory.

Some operating systems, notably Windows, impose hard limits on the maximum number of handles which may be allocated at any one time. In Windows XP, for example, the limit is 10,000 handles. Under normal to extreme operating conditions this limit should never be reached unless one or more programs is allocating handles without releasing them when no longer needed (a handle "leak".) Such leaks can exhaust the system handle pool either very quickly, very slowly, or somewhere in between. Handle leaks can be very slow to exhaust the system handle pool, on the order of hours or days of constant use before symptoms will start. If I'm right in guessing at a handle leak in one of your programs, then the onset of symptoms is 12 hours in your case.

The symptoms of handle pool exhaustion all stem from the inability of programs to allocate new handles when they need them: files will fail to open, graphics (such as icons) will fail to load or will load the wrong graphic, drop down menus may fail to appear when clicked and applications may outright crash.

The immediate remedy for system handle exhaustion is to terminate the offending program or reboot the system. Terminating the program will automatically release all the program's handles back to the handle pool and things should carry on normally, rebooting does the same thing obviously. The only long term solutions to a handle leak start with identifying the culprit. Barring a malware infection, core system applications can generally be ruled out. Using a tool like Process Explorer (with the "handles" column shown) can usually make quick work of discovering the misbehaving program: watch for a program whose handle count steadily increases over time and never significantly decreases.

Once you've identified the program, the options are to discontinue using the program, update to a newer version and hope the bug is fixed, or manually restart the program before it exhausts the handle pool.

The sudden running of Cyberlink - in about 2009. Windows Vista.
The strange radio discussion broadcast - just today. Windows 7.

Since the time frames on 66.66% of the issues are measured in years we can't even begin to speculate with any degree of accuracy. There is zero possibility of testing theories or hypothesis with the same conditions existing since so much has changed with the OS's.

This leaves your Windows 7 issue and less than 48 hours have passed. If you want to follow up on that event please post your topic in the Win 7 forums. The multiple issues over years old is an effort in futility to try and diagnose.
