I use ASUS M2N-PLUS SLI and with 2GB of crucial DDR800 Blastice and NVIDIA Gforce 8500 and creative Sound Blaster 5.1 and three hard disk one of them is maxtor 80 GB PATA and another is 80 GB SATA and another is samsung 200GB SATA and Power 780 Watt. I have this problem when I plug cable power into power and press ON power of POWER , my system began start without any action , I only hear fans of CASE began ON , and nothing happen after 25 second my system OFF and I start my computer with ON button of CASE, for first time I think problem make by power so I change it , but I have that problem again. CAN this problem happen by RAM ??
I think nobody has replied because I don't have a clue what you're trying to say. No offense. Try explaining it again? Abit slower?
So what your saying is that When you have the the PSU switch to ON and plug in the power cable your system attempts to boot but only the case fans power and then it turns off? And the same happens when you press the power button on the case? Do you hear any beeps from the motherboard speaker? You say you have tried changing the power supply? Now try booting with only PSU, Motherboard, CPU and alternate sticks of RAM (if you have more than one) Does the monitor display anything at all?
Do you have the 4 pin power connector plugged into the motherboard? You said the fans come on, but do the hard drives spin as well?
Yes but when I press the power button on CASE , system start and I hear beeps and I go to Windows and use it
Yes I have 4 pin power connector Yes fans of CPU and CASE come on and I do not hear beeps and nothing happen and after seconds my system power off and after that I press power button of case and my system start working
Yes but nothing happen ans I do not hear beeps and after seconds system TURN OFF and after that I press power button of case and system start working
i had this when i tried to power up my new build, it turned out one of the ram sticks wa faulty. if you have two sticks of ram take one out and try it, if it doesnt work try the other one. then if one works and the other one doesnt its the stick what isnt working thats the problem it might be something else, but thats what mine was.
I change my RAM and buy 4GB of Corsair RAM and replace them with Crucial RAM , but I still have that problem I think this is normal.
