Hello.
I have a big problem with my PC and I believe the culprit is my M2N32 SLI Deluxe.
Here is my config:
- CPU: AMD Athlon X2 5200+ (~2,1 Ghz)
- Heatsink: Thermalright 120 Extreme with a Noctua 12cm fan plugged in the MoBo socket.
- MoBo: Asus M2N32-SLI Deluxe
- RAM: 2 x 1 Gb Corsair Dominator DDR2 PC6400CAS4
- Video Card: Nvidia 9800 GTX (512 Mb)
- PSU: Enermax Modu82+ 625W
Nothing overclocked. Other components (HDDs, screen, sound card, etc...) are not important. My CPU and 2 x system fans spin at around 700 RPMS in idle, temps for the 2 cores of my CPU are around 25-30°C idle, 50-55°C load.
My normal start-up sequence went about this way for over 2 years:
- Press power button.
- All system fans spin to max RPM.
- MoBo beeps once to signal "good POST".
- All system fans spin down to normal RPM.
- Video output with information about video card BIOS.
- Standard system startup screen with "press DEL to enter BIOS".
- And so on.
Sunday evening I shut down the system after using it the whole day with no problem at all. The shutdown went flawlessly. I turned off the PSU and the switch on the power extension cord, but left it plugged in the wall socket, as I usually do before going to bed.
Monday afternoon I got back from work and switched on the system and instead of the normal sequence, I got: all fans spin to max RPM, no beep from the embedded mic of the MoBo, no output on screen, then after exactly 3 seconds everything shuts down. I tried again and again, and got the same every time.
Thinking something could have come loose due to thermal expansion (it is the middle of the hot season here) I opened the case and checked every connection, but found nothing amiss. I tried again to power up with the case open, no luck. I started disconnecting everything not necessary to boot to BIOS, meaning HDDs, optical drive, soundcard, case fans, everything. This left me with my minimal config able to boot, that is:
- CPU
- Heatsink + fan plugged in the cpu-fan socket onthe MoBo
- MoBo
- RAM x 2
- Video Card
- PSU.
I tried again to boot, no effect, still 3 seconds of life then shut down. I removed the RAM, then tried with one stick in every slot, no luck. I swapped the video card for and older PCI-E ATI card, no luck. I swapped the PSU with another 500w one, no change.
I tried to power on with only CPU, heatsink, MoBo and PSU: it stays on for a few seconds, the fan spin slowly (not max rpms), then shuts down.
Each and every time, no matter the configuration, I get no beeps whatsoever. I was getting a beep when everything booted ok, so I think my MoBo has some kind of embedded buzzer. I tried to plug in a very old speaker from a very old case (from a time when 486DX2 was all the rage) and got nothing from it, either.
I tried to clear the CMOS, removing the battery and leaving the cap on jumpers 2-3 for over 15 minutes, nothing. I replaced the battery with a new one (the MoBo was bought in Feb-2007), cleared the CMOS again, no change at all. I removed the heatsink, cleaned the old thermal paste from both surfaces, reseated the CPU, put on a fresh coating of thermal paste, reseated the heatsink, nothing changed.
I am at my wits end. I hardly believe my CPU is fried, since I never overclocked it. I don't have a compatible stick of ram to test the system, only my 2 old ones, but I hardly believe a bad stick of ram could make the system shut down: fail to POST or to boot to BIOS, yes, shut down, nope. I also can't believe the CPU protection failsafe could kick in after 3 seconds, a CPU just can't get so hot in 3 seconds that it risks frying.
Am I experiencing a zapped BIOS flash-rom? Is my BIOS gone from the chip? I tried the recovery method described on www.biosman.com to recover a bad Award bios, but I don't get a response from either a USB stick loaded with the described files, or the original ASUS motherboard CD in the optical drive. Still 3 seconds of power, then it shuts down.
The computer ran fine for 2 years with this exact configuration, I experienced no instability, no blue screens, no freezes. Temps were fine last time I checked. I cleaned it with compressed air no more than 2 months before it gave me this bad surprise.
Any help will be greatly appreciated.
And sorry for any errors or strange expressions: English is not my native language.
