Windows 7: Please help! computer randomly freezing, no error message

My computer has been running fine for about a year, I have reinstalled windows 3 or 4 times and I haven't had any major problems. During this last re-installation I formatted my hard drive to get all my space back, I'm not sure why but since I formatted my hard drive windows randomly freezes and It isn't during any specific program so I don't know what could be causing it. please help.

Tatertot,

Welcome to SevenForums.

So that your SystemSpecs travel with your posts and are always available, would you please carry out the following:

Update your SevenForums System Specs
User CP (located on the top menu bar) |
Your Profile | Edit System Spec (left-hand column)

To gather info, use Speccy (my favorite) or SIW or System Info

In the System Manufacturer Block, enter:
Manufacturer and Model and
ADD the word laptop, desktop, netbook or tablet.
For example:
Toshiba Satellite L305D notebook.

Provide full windows version info, for example:
MS Windows 7 Ultimate SP1 64-bit

Use the “Other Info” block for Optical Reader,
Mouse, touchpad, wifi adapter, speakers, monitor, etc

Scroll down and click on SAVE CHANGES.

You will find that in Speccy, you can select info from the display
using your mouse/touchpad and then paste that info into your specs.

SIW is a marvelous program, but the free version does not offer
this capability.

====================================================
====================================================

Next time when your computer freezes, if possible:
CTRL + ESC keycombo | type RESMON | ENTER key
Is there an item in red?
If yes, right-click on same and choose "Analyze wait chain".
Work your way down the chain, note the name, and also choose end process.

If still hung, then repeat.

=============================================

Install SPECCY, link in my signature and use same to keep an eye on your temps.

=======================================
=======================================
Attach to your next post, the startup.txt file which the included script places on your desktop.

I attached the startup.txt like you said and it hasn't frozen again yet so I can't tell you if that ctrl esc combo that you told me to try works yet.

WIN | type MSCONFIG | ENTER | STARTUP tab |
Uncheck ALL except for:
REBOOT!

You have just told Win 7 to not run unchecked programs at start up time.

You have not disabled the programs. They will be run when needed.

WIN = key with the Microsoft logo on top

TaterTot,
You computer is just waiting to be infected!

Immediately install the very best: Microsoft Security Essentials, MSE.

Link to MSE is in my signature.

Ok well I unchecked everything and installed MSE, but my computer just froze again, I tried the ctrl esc combo but nothing happened and to shut my computer off I can't click the restart button on my tower I have to push the power button otherwise it doesn't work (the restart button usually works fine)

TaterTot,
Since you've been surfing the Internet naked so to speak, then the following is going to be necessary to rule out some possibilities:

HOW TO USE WINDOWS DEFENDER OFFLINE ON A USB STICK
Windows Defender Offline
· is a free standalone, bootable malware and virus remover from Microsoft.
· performs an offline scan of an infected PC to remove viruses, rootkits and other advanced malware.

Download Windows Defender Offline (about 764 kB)

You will have the choice of downloading the 32bit version (x86) or the 64 bit version (x64).
The link will help you determine whether you are running a 32 bit version or 64 bit version of Windows

NOTE!! You can download and prepare a 32 bit version using a 64 bit version of Windows
NOTE!! You can download and prepare a 64 bit version using a 32bit version of Windows.

You run the 32 bit version on a 32 bit version of Windows.
You run the 64 bit version on a 64 bit version of Windows.

The 32 bit download file name is: mssstool32.exe
The 64 bit download file name is: mssstool64.exe

For the curious, this program was originally name Microsoft Standalone System Sweeper.


INSTALLATION:
You will need an Internet Connection.
Insert 512 mB (Microsoft’s 256 mB is no longer accurate) or larger USB stick into a usb port.
Run the downloaded program--mssstool64.exe or mssstool32.exe
NEXT button
Choose the option On a USB flash drive that is not password protected
NEXT button
NEXT button
.
The install program will format the usb stick using the NTFS format.
The install program will download about 210 mB.
The install program will name the USB stick WDO_Media32 or WDO_Media64
The WDO_Media32 usb stick will have used space of 255 mB (268,140,544 bytes)
The WDO_Media64 usb stick will have used space of 282 mB (296,165,376 bytes)
You can expect the number of mB to increase as more malware appears.

UPDATE Windows Defender Offline USB stick:
· reinsert the usb stick
· run the installation program, mssstool64.exe or mssstool32.exe, again.
· the update will download about 66 mB (mssstool32.exe) and 68 mB (mssstool64.exe).

Since the malware database is sometimes updated several times in a day, always update before running.

PERFORM AN OFFLINE SCAN
Bootup your computer from the USB stick
Windows Defender Offline will automatically perform a quick scan.
After the quick scan finishes, Choose Full Scan
Select all of your drives

The initial, full scan can easily take several hours, but
Remember, your computer is being very thoroughly checked for all types of malware.

Looking over your specs, there is the possibility that you need a heftier power supply. An inadequate power supply would also explain the freezes.

Also, with power cable removed, remove the cover from the computer. With compressed air can, blow out all dust.

Leave the cover off. Direct a desktop fan, a table fan, or a floor fan directly at the computer.

Use Speccy as an easy tool to keep an eye on your temps.

I don't think it's the power supply because it was working fine with that power supply since I got it last year and I sprayed the compressed air in it yesterday but it didn't change anything
