hi, you RAM must be out of order, pull it out from the mother board and clean the metalic end with little spirit. Still you face the same problem then your OS may not be loading properly due to some kind of infections.
If you have added any new hardware of late then it could be taxing you power supply. This happens after a few years of use. Could even be enough dust if your case to cause a couple of points to become connected, or even over heating. Good luck keep us updated, hope that helps.
Listen, here is the solution >>>>>>>>>>>> Open you cab, remove motherboard , remove CPU. Clean it with cotton or cloth It will be great if you use Vacuum Cleaner to clean it Install motherboard, THEN INSTALL CPU ON MOTHERBOARD. DO NOT INSTALL CPU ON M.B. BEFORE INSTALLATION OF M.B. Very IMP - Make sure that you have attached all screws PERFECTLY.
First you say you don't know, then it is the CPU? Do you know or not? Seriously, most of the suggestions people made here ring true. It is a process of elimination. You check this, then that, then something else. If it is the CPU friend then go buy another unit, that one will make a great boat anchor. It sounds like a short in the monitor. Audio cards rarely go out, so that is your most likely suspect. There is no way a forum can diagnose your computer hardware issues. They can make suggestions as to cause, but no legitimate diagnoses. Software issues are a different story and there is a remote possibility that it is some software problem in your driver, etc. Hard to tell from Cyberland.
