Most common PC problems can be narrowed down to either System Optimization or Hardware related issues. Therefore, Many solutions to the widely used Windows 95, 98 and ME Operating System, can also be applied to NT and Windows 2000 XP, Vista and later operating system.
If you're having optimization issues, then you should run the ScanDisk and Defrag utilities 95/98/ME or NT/2000/XP/Vista/Vista at least once a week to keep your PC optimized. This will also reduce all software and program applications from giving you a Dr.Watson error, Blue Screen of death, GPF and the famous illegal operation errors.
If you're having a Hardware problem, then mostly likely it is related to a wrong driver or an IRQ/DMA conflict issues.
To solve these problems here is the way I tackle it: -
Registry Cleaner or CCleaner Install either ones (Skip registration) both tools can clean, repair and backup your Windows registry. However, CCleaner can also erase your PC’s Internet and applications history and tracks. Make sure to go to Options/Settings and select secure erase (7x over writes) Works for Win9x, ME, NT,Windows 2K, XP and Vista.
Click Here to Download a Program file called Bkups.bat that will backup your (95,ME and Win98) current configuration to a folder called BKUPS on your C Drive. Run it and watch .
Click Here to Download this other Program file called Recover.bat that will Restore your (95,ME and Win98) system files from the saved BKUPS folder on your C Drive.
Then, I make sure I have the correct driver to the hardware I want to install also I have on hand the Windows Operating System CD. Otherwise, I 'll download the driver from the vendor's web site or I may look for the it at the following Free driver web site using driver for the user id and all for the password to logon >>> http://www.driverguide.com .
Here is what a Device Manager should look like if a the PC has no Hardware conflicts.
Armed with this I reboot my system and go into the safe mode to remove all duplicate instances of the Hardware.
(You can go into the safe mode by keep pressing F8 when you restart your computer and select menu item 3)
Once in the safe mode right click My Computer, then left click Properties then select Device Manger Tab.
Remove all duplicate hardware instances from the device manager registry. Then reboot. your windows will automatically re-detect everything and reinstall the proper drivers and will prompt you to insert the driver diskette for the hardware you're installing.
You can Go back to the Device Manger During the regular Windows Mode and see if you have any Red X or Yellow Exclamation point that will show a disabled device or existing IRQ or DMA conflict. This problem will go away once you install the right driver. However, there are some cases where you may manually select an IRQ/DMA settings that will make it work.
