Computer freezes randomly

[bigboy54]

First time posting here...over the last couple of days my computer randomly freezes and i have to force reboot it happens at random...so i checked the event viewer and it said The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

It would be nice to be able to see your System Specs.

There are many reasons why a PC " behaves" this way.

These annoying " gliches" may be caused by an overloaded hard drive, overworked CPU, Malware, running 2 AV 's, unnecessary data, Browser addons or you may have unnecessary programs running in the background etc....

What follows is a series of generic troubleshooting steps that you may care to try...

*Make sure all intake/exhausts vents are clean along with all fans.
Get some temp monitoring software for cpu, gpu.

* It could be a hard drive that is going bad or corrupted.
To check a hard drive See Check Disk...

* In an administrators account type cmd in search.
In cmd type sfc /scannow.
This will report and fix minor problems.
Take note of what is said at the end.
Should your computer freeze, try to do the tests in safe mode.

* Go to search, type device manager and look for any yellow warning markers.

* Re Event Viewer ID 41. Most of us get this error every so often.
Keep it under observation.

* If overclocking, restore to original.

* Try in safe mode; report back if it works properly.
Getting into Windows Safe Mode

*Clean boot. You may discover what is causing your problem.
How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

*Run a scan with Malwarebytes.
Please download the free version of Malwarebytes.
Update it immediately.
Do a full system scan
Let us know the results at the end.

Malwarebytes : Download free malware, virus and spyware tools to get your computer back in shape!

*List all the Security software you have ever had installed & currently have now on your computer please.

* Browser addons can create problems.
Check how many you have on your various browsers.
Is each & every one really needed?
