A couple of weeks ago, suddenly my computer turned off automatically and after 2-3 seconds it started beeping. It beeped for 15 times repeatedly. I took that normally. But since then, when I turn my computer on, after 2-3 hours of running, the display goes black. It is happening again and again. I have to turn the computer off and on again.
After a week, I changed my motherboard. It worked fine for a week. But, the same problem is happening again. It restarts with beeps repeatedly, then the display keeps going black.
Yesterday, I searched CCM and found a suggestion saying that 'Uncheck Automatically restart' in system failure. I did so.
After doing that, I kept my computer on for 2 hours. I have not found that problem yet. So could you guys please tell me what's the reason behind this?
First check your RAM. A bad RAM can create such issues.
Remove the RAM from the slot, clean it and place it back properly or try another slot. If you are having two RAMs then remove it, place only one RAM and check if you are able to use the PC without any problem.
If the problem still exists then change the slot. If you still having the same issue then try the above procedure with the other RAM.
thanx man....it works..hey i've also made some changes like in power option I changed auto turn off display and auto sleep mode time into NEVER mode and uncheack auto restart in system failure....now it's been running smoothly yet.
