I have a computer problem that no one seems to be able to figure out.
The problem: During Startup Cmos does not properly load settings to start the Heat Sink Fan (best guess) ; it turns for half second and turns off. During this initial startup all fans come on the Hard Drive spins up and the Video Card Intiates. Everything appears to be normal with the exception of the Heat Sink Fan. The result is a blank screen.
Trouble shooting so far:
1 Unplugged the PSU from the wall waited for a few seconds and the selected the case power switch. No change
2 Unplugged the PSU from the wall and held down the Case Power Switch for 20 seconds plugged it back in and powered up. No Change
3 Unplugged the PSU switched the Jumper to join the CLR_CMOS for a few minutes switched the jumper back plugged the PSU back in and powered up. No Change
4 Reseated Video Card and Ram. No Change
5 Tried one stick of ram at a time. No Change
6 Reapeated #4 and #5 followed by #3. No Change
7 Removed comos battery. Powered up. No Change
The RAM Led lights Contantly on the Motherboard. On this particular motherboard the DRAM LED checks the DRAM in sequence during motherboard booting process. If an error is found , the LED next to the error decice will continue lighting until the problem is solved. Now I am not a Computer Scientist so I do not know what the exact "sequence" of the booting process but I do know that the CMOS holds the hardware setting that load into the bios. So I am wondering why the RAM Led would be blinking. In what way does the CMOS loading process affect the DRAM if any or does it check the RAM. Why is it blinking... in the USER Manual it says the the LED checks the DRAM. That makes no sense...an LED cannot check the DRAM.. I don't know what does but my guess is that the CMOS checks the RAM I could be wrong. Could the CMOS be corrupt. It appears to me that the LED starts blinking before the bios ever has a chance to load. The light starts blinking simutanueosly with power up.
The CMOS has been cleared several times during this troubleshooting process. Does anyone have any idea what this could be. The computer was running flawlessly and just shut down to a blank screen with no Heat Sink Fan. This has nothing to do with an after boot to windows or a BSOD I have had zero errors with this computer. It will not even load the bios or at least that I can see and I doubt it would work properly without the Heat Sink Fan running.
It is a new build and here are the specs:
CPU AMD Phenom II x6 1090T...Hard Drives are Crucial C300 and Samsung F3....Windows 7 Pro 64 bit...Motherboard: Asus M4a89gtd Pro/Usb3...Memory G Skill 1333Mhz Cas 7 1.5 (sx4gb)8GB Power Supply Corsair 750TX Graphics Asus EAH6850....Case Antec 900 The Computer was never Overclocked and was flawless.
Here is a link to a video the shows the 1 second cpu fan startup. https://picasaweb.google.com/112977624385357368142/Mar30201105#5590035606769907074
I have already recieved an RMA but this is a last ditch chance to fix it before I send it off
Any Help would be much appreciated
