So I was gaming today and all of a sudden the computer shuts down and the screen says something like CPU overheated and to press F1 (or something like that). I didn't press F1 and instead tried to reboot. Since then, it won't reboot, even after I waited several hrs for the whole tower to cool down (it was indeed quite hot). What's happening now is that when I press the power on button, the fan and its LED lights and the HD turn on for ~1 second, then it shuts off. there's NO beeps or any signal to the monitor at all. The funny thing is that it tries to do that repeatedly on its own, even though I'm no longer pressing on the power button. The only way to stop this cycle is to unplug the back. I tried to clean up any dusts in side the case and also didn't feel any loose screws or anything. I 'm not sure what exactly got fried and how to fix it.

Please help thanks :cry

 

Hmmm. How long had you been using the computer before this happened? Is this a new build, or one you have been gaming with for a while?

I notice you are liquid cooled . . . it's possible that something in that system failed. Check to make sure the fluid block is properly seated on the CPU. It could have come loose, and if it's not making contact at all an i5 would overheat PDQ. I'd think you would still get into the BIOS far enough to get an error message, though . . . :confused

Another possibility is your power supply has failed. I had a computer act like you are describing (just without the CPU overheating warning ) and it was the power supply. Perhaps its output got so low your cooling system stopped working which generated the message? Then on reboot the PSU completely failed? Pure conjecture, I know, but it's a theory that fits with what you describe.

 

thanks for the reply. I had it for about 3 yrs. After I wasn't able to turn it on again the next day I took it to the company that built this to get it fixed. we'll have to see what happened. the guy preliminarily said it's the liquid cooling since it usually busts within a year or so, and I had it for 3 already. But like you mentioned, I expected to at least get into the BIOS to configure :confused

 

I had a similar problem when a friend overheated and lost his power supply.
If you have a PSU you can swap in, it is worth a try.
