PC Turns on but no post beep or image

[andrescelano]

Ok here we go. I have been using my PC for day to day use for about 7 months now without any problems at all. This morning, I turned it on and something weird is happening. The PC turns on and then it turns off again (this happens normally but today it turned off really fast) then it boots on again, the fans all start spinning and as far as I see all Leds work, the motherboard led also turns on but there is no post beep and the pc just stays like that, turned on but without anything else that works. No image turns on and i can not even press the power button to turn it off again. I have to manually press the PSU button for it to turn off. Please help me guys.

First try RAM in different slots and also just one at the time.
Trying another RAM also would help. If you have any old DDR3 or can quickly loan one from someone.

You'll usually get a beep code if there is no memory. Remove all memory to check if RAM is the problem. If you get a beep code try each stick of RAM by itself in the first slot.

If still no beep code after removing all RAM then it's probably the PSU. PSU's will shut down if their output voltages are not within specifications. That might also be why it won't turn off at the power button. The power button connects to the mobo but the PSU isn't communicating with the mobo any more.

Or it could be the CPU. If it's been running too hot it may be damaged so the code in the BIOS has no processor to use to produce a beep code.

Heh I fixed it, turns out the problem was a faulty HDMI cord. I went to IbreakUfix and it worked over there. Anyway, thanks for trying to help me out guys, appreciate it a lot (Typed from my pc)
