Hi, i've been having this problem lately where my computer wont post randomly.
I'll turn on the computer but it wont post and all the fans will run at 100%.
I'll also see the red LED on the motherboard signalling a CPU overheat.
Heres the thing...
Sometimes the computer DOES boot and i check the CPU temperatures and they're in moderation. It seems to be completely random whenever it does boot and when it doesnt.
I've tried reseating the CPU Fan and that helped for a day or so, but not its back to normal, wanting to die.
I don't know whats going on, whenever the computer doesn't post, i try to feel the temperatures of each of the components with my hand and they don't feel like they're making any heat at all.
I can only guess that this is some kind of problem with the motherboard's temperature sensors but thats just my guess.
Heres the list:
Intel Q6600 at 2.4Ghz
2Gb of Corsair RAM
700w OCZ PSU
Intel Bad Axe 2 (D975XBX2)
Okay, so i was getting frustrated and tried to see if my CPU fan was being stupid again so before i booted it up i tried to shift it slightly in one direction to see if it was tilted in some way. I slightly tilted it to the left and it turned on. I then heard 4 beeps with 2 beep successions, kind of like "Beeeee booooo" then "Beeeee booooo" (yeah, i couldn't think of an analogy). The computer then said that the CPU shut down due to a thermal event on the start-up screen.
Okay, so by now i would know whats going on except for the fact that after this short episode, my computer now turns on fine until i leave it off for who knows how long. Maybe 30 minutes to 2-hours? Should i just buy a new CPU fan?
Thanks for the reply.
I have one more question,
Usually whenever a CPU overheats, it at least turns on for a few seconds then the light comes on, normally.
With my problem, it simply boots up to an overheat, like it was waiting in surprise for me.
Do you think maybe its just not contacting the CPU enough on startup and its having some weird kind of thermal problem?
Oh yeah, i have a Tuniq Tower, its not a pushpin like the stock cooler i had.
I've read this thread a few times, and still can't tell:
- What cooler do you have installed on the cpu now?
- Did you use thermal paste on this install?
- When you get an "overheat", is the fan spinning?
- Looking at your mobo's manual ( http://download.intel.com/support/motherboards/desktop/... ) I can't find any reference to a "red led on the mobo signalling a cpu overheat"
-I currently have a Tuniq Tower.
-Yes i am using Thermal Paste
-When i get an "Overheat" the fans are all spinning at 100%
-I couldn't find any reference to a red LED either, but there is one next to the CPU that turns on whenever it overheats.
The thermal paste and cooler have worked fine for 2 years and now it suddenly started this problem out of nowhere.
Hi, sorry for double posting but i really need help...
I just changed out my Tuniq Tower for an Artic Cooler 7
I just got the problem again.
It seems that the problem fixes itself for about a day or so if i put a lot of pressure on the Heatsink. Then it comes back randomly, just boots up thinking that it's overheating and the red overheat LED turns on the second i push the power button.
I'm thinking that its the motherboard now, i don't know how it could be a CPU or a PSU problem.
