Windows 7: Random Freezes

Random Freezes

I am beginning to get really frustrated with my computer. It never used to freeze but recently it has begun to randomly lock up once or twice every day for the last few weeks. I can't find any similarities in the freezes as it will freeze with any combination of applications open. All applications don't move and the mouse doesn't move either, it literally looks like a frozen screenshot when it happens. It also happens with no warning, just randomly I will notice the mouse isn't moving anymore and notice its frozen. The only way to unfreeze the computer is to manually turn off the power and reboot only to have it freeze again within the next day.

Any suggestions on what I should do or how to find the problem?

Welcome

The most ususal reason is RAM, type memory diagnostics in search and take the test over night. It is equally common that malware is causing the problem. Make an antivirus scan as well as dowloading malwarebytes and ruan a scan

In addition, you will find many of the common causes listed here

I've run scans with both MalwareBytes and ESET Smart Security, both came up clean.

I'm planning to run Memory Diagnostics tonight, I'll see what that comes up with.

In the link you gave me:

1. Run Virus Scans + CCleaner weekly. Will try disabling Indexing service but I doubt that is the problem.
2. Event log displays this for the most recent crash:

The previous system shutdown at 2:04:07 PM on ‎6/‎2/‎2010 was unexpected.

and

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

But that is all.

The links that I sent are quite generic. If you are fairly sure that a particular test is not appropriate for your situation, why not put it on hold for the time being. The memory test is important.

I tested my computer overnight. I watched the test start and then went to sleep. When I came back my computer had successfully restarted but there were no windows open indicating the results of the test; I assume this means there were no errors?

What else can I try now?

Yes, I will give you additional help by looking for the tut on how it should be done. Check here, soon. I will post as soon as I find it.

OK, here is our excellent Tutorial on how to run Memory Diagnosis. If it still does not give the proper results use memtest86, as shown in my other post.

Now that I think about it, use this test instead it is more thorough

I did the memory diagnostics test to the letter last night and let it run, even on extended this time. I watched it start and the watched the test go to 10% before going to bed. I woke up this morning to find no report again, just a standard desktop after booting up with no windows open.

I'll try this Memtest now I guess. I noticed it says Memtest86, will this be a problem on my x64 machine?

Edit: After some searching I noticed that Memtest86 hasn't been updated in over a year, but a group made something called Memtest86+ that was updated last month, is this a better option?

Also it appears burning to a CD is unavoidable so I'll have to dig a blank one up which may take me a bit to find. (Haven't used a CD in several months :P )
