My Computer Freezes Consistently

Hello ykisana,

Please follow this tutorial to determine which hardware is at fault, with particular emphasis to steps 8, 9, 10 and 11:-

Troubleshooting Steps for Windows 7

Hope that helps!

We will need more information to answer your question. Performing the tests in the link from solarmystic may supply some important clues.

It is very helpful to us to know your system specs. You should fill out the "My System Specs" form in your user profile for SevenForums.

But the primary suspect for hardware side freezing is always the power supply and/or power related problems.

Having the CPU fan turn off by itself is a major problem. The CPU will shut off to protect itself from overheating, therefore minimizing any damage, so I would be surprised if the CPU was bad. But you (we) need to determine the cause of that fan going off. That cause could affect everything.

The most common cause of computer freezes is a corrupt registry.
Most likely your registry is bloated and overstuffed with an assortment of useless pieces of data. The operating system while running your computer has to pick its way through all this excess material. There will be bits of programs which were not completely uninstalled, parts of programs which were never completely installed, fragments of miscellaneous data, useless drivers, and a multitude of other bits and pieces.
The answer is to clean your registry and remove all the material which is not needed.

Get the best one, and completely clean your windows registry with a few clicks of the mouse.

Often there is also spyware which is using your computer for nefarious purposes and slowing its operation.
The answer is to scan your pc with a best anti-spyware to clean spyware/trojan/virus

Thanks.
I can see from your specs that you do not have the typical case of too much hardware being run on a too small power supply. And I can eliminate the usual problems that can be caused by video cards and multiple hard drives.

Your 450W power supply is plenty big enough for your system, but that does not rule out a defective unit. Do you have a multimeter that you can test with?
Otherwise, can you borrow a known good PS from another system to test?

Let's see what Memtest and the hard drive diagnostic tells us.

As for temps, in your BIOS settings there should be a "Hardware Monitor" selection or similar. In there you will find the temperatures being reported for the major components by the motherboard. What do they show?

And one of the simplest tests to see if you have temperature problems is to run the system with the sides taken off, and maybe point a house fan directly into the case while you run it. If the freezing goes away in that test then you have your answer.
