Computer freezes can occur at any time your computer is operational—during system startup, while you are working on it, and during system shutdown. Some of the common causes of computer problems are too many programs loading at system start up, display problems, driver, and software conflicts, overheating of system components, hardware conflicts, malware infections, and registry errors.

In case your system invariably freezes at system startup, it usually implies that there are way too many programs loading at startup. Therefore, to fix these errors, you will have to stop unnecessary programs from loading during the startup process. To do this, first check the Start > All Programs > Startup folder. If you see any unwanted programs listed here, right-click and select Delete, to remove them. Next, open the System Configuration utility by running “msconfig” from Start > Run. On the Startup tab, clear the checkboxes of the programs that you do not want to load during system startup. Select Apply and click OK to implement the changes and restart your PC

The Windows operating system constantly refers to the registry to get information about all of the components such as hardware and software which are installed on the computer. The registry tells Windows what to do and how to access the various programs, files, and processes.However, the registry can contain bad information which sends Windows off doing useless tasks or running unneeded routines. Sometimes errors occur including the freezeing. Other times the system slows down. Because of the sheer number of factors that can affect the registry, there’s no one size fits all approach. You can’t just go into the registry and remove the bad information because it’s nearly impossible to decipher which information is good and which information is bad. That’s a job better suited for software. I should like to commend Registry Easy http://perfect-your-computer.com/ to you ! You can try ! Good luck!

Be VERY careful what you stop from running at startup. You may end up with a non-responsive system.

First reseat your RAM or replace with known good/new ones.

Check the HDD...

You will need to get hold of an install disk for your operating system (XP/Vista/Win 7), borrow one if possible, and boot with that (any one will do as long as it's the same version eg:Home/Pro/Basic/Premium etc.).

Note: To boot from your Windows CD/DVD, the BIOS settings on your computer must be configured to do this. On start up keep tapping either F1, F2, F10, (Be Aware that some manufacturers use F10 for system recovery!) Esc, or Del, to enter the BIOS set-up. Look for "Drive configuration", "Boot order" or similar and make the CD/DVD drive the first boot device. Save settings and exit.

Insert the Windows CD/DVD into your CD/DVD drive, and then restart your computer.

When you see the "Press any key to boot from CD" message, press a key to start the computer from the Windows CD/DVD.

Click to select any options that are required to start the computer from the CD/DVD drive if you are prompted.

When the "Welcome to Setup" screen appears, press 'R' to start the Recovery Console.

If you have a dual-boot or multiple-boot computer, select the installation that you want to access from the Recovery Console.

When you are prompted, type the Administrator password. If you don't know the administrator password, there probably isn't one so just press Enter/Return.

At the command prompt (C:\>), type

chkdsk /r

(note the space between chkdsk and /r)

and press Return/Enter.

When the scan finishes, re-start.

Then check for malware...

The key words here are SAFE MODE!!!

Download, (if you can't get on-line, have a friend download and copy to disc/flash for transfer) install, update and then, in SAFE MODE* run full scans, with these programs...

http://download.cnet.com/1770-20_4-0.html?query=Ad... Ad-Aware free

*** Important, when downloaded/installed/updated disconnect from the internet ***

Then re-start.

If you can't run a scan, go into the scanner's folder and re-name the .exe file to something like 'MyFile.exe' and try in safe mode again. Some malware prevent the execution of anti spy/mal/virus scans by blocking them by name.

You should consider getting a good Anti-Virus program.

Try one of these free ones...

***Never use more than one, active, anti-virus program at any one time***

*Note: On start up (before Windows loads) keep tapping either F5 or F8 (be aware that some manufacturers use F8 for system recovery!) then use arrow keys to highlight 'Safe Mode with networking' and hit Enter/Return, click on a user account, enter the Administrator password (if you don't know it, there probably isn't one so leave it blank) and hit Enter/Return.

** It has been noted that Malwarebytes should be run in 'Normal Mode' unless that isn't possible!
