BleepingComputer.com: Windows XP home Boot problems

Ok guys here's the deal...hopefully i can be as detailed as possible but im not exactly too tech savvy :/

Just started having an issue with my computer started getting very laggy and having problems running programs that have been installed for a while. The other day went to startup my computer and it would get to the loading windows XP screen(and this is where it gets wierd/my guess work comes in) finish loading and then drop out on me and restart the computer from the BIOS screen. I decided to check the BIOS to see if something got deactivated or anything like that and everything looked good to go. I then let the computer resume its startup and it took me to a screen saying there was a problem during the last startup chose to start in regular, last known working setup, safe mode with networking, or safe mode. Selected the last known working just in case something may have been installed without knowing it and the same thing occured, got to the loading windows XP screen and the system restarted after it had finished loading. Thought it could be malware or a trojan or somesuch so i went on safe mode w/ networking and downloaded spyware doctor(property of PCTools) and ran a full scan came up with nothing, as well as did my regular scan and came up with nothing. Im kind of at a loss for what to do. Any advice would be great and thank you in advance

**EDIT** after the windows XP screen goes black i heard a click from inside my computer like one of the drives was turning off and "NO INPUT SIGNAL" showed up on my monitor **EDIT**

EDIT: Be patient, someone from our Malware Team will assist you shortly ~ Hamluis.

Hello there,

Please do not run Combofix unless you are instructed to do so! Its an extremely powerful tool that can cause quite some damage.

Please download Malwarebytes Anti-Malware and save it to your desktop.

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

• Make sure you are connected to the Internet.
  
• Double-click on mbam-setup.exe to install the application.
  
• When the installation begins, follow the prompts and do not make any changes to default settings.
  
• When installation has finished, make sure you leave both of these checked:
  • Update Malwarebytes' Anti-Malware
    
  • Launch Malwarebytes' Anti-Malware
  
  
• Then click Finish.

MBAM will automatically start and you will be asked to update the program before performing a scan.

• If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  
• If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.

On the Scanner tab:

• Make sure the "Perform Full Scan" option is selected.
  
• Then click on the Scan button.
  
• If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  
• The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  
• When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  
• Click OK to close the message box and continue with the removal process.

Back at the main Scanner screen:

• Click on the Show Results button to see a list of any malware that was found.
  
• Make sure that everything is checked, and click Remove Selected.
  
• When removal is completed, a log report will open in Notepad.
  
• The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  
• Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  
• Exit MBAM when done.

Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.
