Very FROZEN computer

So, I have a computer that keeps freezing up and it gives no BSOD or anything, the screen and mouse just freeze exactly where they are at.

I was having a BSOD a few days ago that was listing a file for the graphics card so I uninstalled it.  Other than that, I can't think of any changes.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

It may not be anything you did. Could be hardware has gone bad, for example. Run memory test is a good idea. Also make sure your fans are all working so nothing is overheating.
Dr. KlahnPrincipal Software EngineerCommented:
How old is the system?  As components age, they can start producing this behavior.  Electrolytic capacitors, in particular, have about a ten year lifetime in the best of conditions; for the units located next to modern CPUs that tend to run hot all the time, five years or so can be expected.

System is about 5 years old.  I hate to throw, what seems like, a good computer away.  Worst case I'd like to try to salvage the RAM, hard drive and video card.

I'll run some memory tests to start, just to try to rule that out.
CompTIA Network+

Prepare for the CompTIA Network+ exam by learning how to troubleshoot, configure, and manage both wired and wireless networks.

If you have a spare power supply or can borrow one, try that first as this is usually a relatively easy changeout.  A flaky power supply can cause all sorts of strange problems.  Then if it proves to not be the power supply, that's one possible issue eliminated and you can proceed to investigate other possibilities.

I like the power supply idea too.  I'll try it for sure.

I forgot to mention it's sometimes possible to check for memory issues by removing half the memory and see if the problem stops. If it doesn't swap it with the other half. Keep in mind some systems are picky about what slots the memory is in, so make sure you know about that before you start the test.

While you are in the case, also check to make sure all connections/cables are tight.

in such cases - start by posting the pc - or motherboard model and some specs about the hardware, and how frequent the freezing is
what i do is eliminate devices that can cause it  - by disconnecting them - then run without them for 2 to3x the freezing period
start with disconnecting or removind extra disk drives, cd drive, and controllers, and external devices
after that, try running with half RAM, or even 1 ram stick - or swap it (once one stick is proven good, you can use it to run other tests with)
then start swapping remaining parts  - PSU, cpu, etc...till the cause is found

you can also start from a minimum setup - then work upward, like i described here:

Have you tried another profile?

The first help for slow computers (not in this order):
Run Disk Cleanup
Check out Startup items (Task Manager)
Check AV activity
Check RAM and CPU load
Run deep virus scan
Check Event Log for any errors
Update graphics card driver

You might also try this:
Perform clean boot without any services and startup items. Results?
Get into Safe Mode and run what you need. Results?

Open task manager to see if there are any programs consuming too much RAM, CPU, Disk etc.
If it freezes completely for few seconds and then gets back, it might be bad contact of RAM, CPU, Motherboard or any of these have gone bad. Use utility provided by manufacturer to diagnose.
I'd double check every connection and device contacts. Would also reset the BIOS and check if there is any update available. Check the status of the computer by replacing or removing components one by one, starting with the graphic card if possible.
Hello ThereSystem AdministratorCommented:
Also check if there isn't any Windows Update pending.

Pay particular attention to the CPU fan / heatsink.
Over-heating problems in that area, will definitely cause "freezing"

I threw a new hard drive in, just to try, and it seems much more stable.  I think one of the problems was an old pending display driver update, as mentioned by @Hello There.
nobusCommented:
check also event viewer for problems at the freeze time
Brian BEE Topic Advisor, Independant Technology ProfessionalCommented:
Since the author replaced the hard drive, saying the video driver was the solution is pure speculation. Truth is we don't even know for sure if the problem is solved because there was no indication of the frequency of the crash.
Obaid ur RehmanTechnical and Operations ManagerCommented:
Agree with @Brian. Many experts hinted towards hardware which of course includes HDD, replacement of which solved his issue. If we are to give benefit of doubt here, the points should be distributed to everyone who's suggestion is relevant to HW particularly HDD!
Hello ThereSystem AdministratorCommented:
Let the author decide.

Hi South Mod. I see two resolutions:

Since all the ideas are valid towards fixing this type of problem, close and spread points amongst all the answers. This will help others with the same problem identify what to do. That is what I would recommend.
OR Since the Author never told us how often the problem occurs, per my earlier post, we don't if any of the Experts actually gave any useful advice and therefore the question should be deleted.
