i own a pentium 4 operated PC! its a older one and it has no SATA port connection!! i recently bought a DVD ROM (for upgrading from a CD ROM) which has a SATA cable only!! so i had to buy and use a SATA-IDE converter all the connections were made! the power cables were also connected

Hi
First things first. Make sure all the cables are in firmly and are not faulty, also make sure any add-in cards such as graphics cards are firmly pressed in and if needs be take them out and re seat them.

Try doing a virus or spyware scan, even though it may appear that a piece of hardware is causing the problem, viruses can also cause blue screens and annoying messages. A good free program to run though would be Malwarebytes.

Another main problem can be out dated drivers or software. Try going to the manufacturers website and downloading the latest packages. These can almost always be found in the download or support area of the website.
