Black Screen
Hello all,
I have been having strange problems in since week with my Computer in which it will not load/boot up the first time and it would take about 3 or 4 times (holding in power button) and eventually it would load up and then start Windows 7 without any problems.
When I power it on there is just a black screen (monitor goes into power save mode) all my case/heatsink/gpu fans and LED's are on and DVD drives are on. The reset button doesn't work though (or I cant tell if its working).
Here is my specs:
AMD Athlon X2 6000+ (no overclock, 3 months old replaced a 4600+ for upgrade)
Gigabyte GA-M57SLI S4 (latest Bios update, had this mobo for 3 years)
6 Gb PNY 880mhz DDR 2 (2gb-2gb-1gb-1gb)
2 x 1GB Gainward Bliss Golden Sample 8800GTS (year old)
900w Coolermaster PSU (year old)
Antec 1200 Case (year old)
2 x 500 Seagate Sata2 HDDs (one is 2 years old another is 1 year old)
------Timeline of events-------
>>December 19th 2009 - Upgraded my CPU to 6000+ for better performance.
>>December 20th 2009 - Updated BIOS so it could recognize the new CPU model.
>>January 3rd - Cleaned out computer with airduster and reconnected everything.
>>Middle of January - Installed Windows 7 Ultimate x64
>>Late January - Moved my harddrives for cooling reasons into a new slot in my Case. After that I couldnt detect one of my harddrives (data one with music and unimportant stuff) and still does not show up in POST screen or in Windows (presumed dead).
>>February 27th turn on Computer in the morning and get no loading screen just black. CPU fan is running at high speed and case lights are on.
-------------------------------------------------
Detailed problem:
+++++Please note my Motherboard has never did any POST beeps that I am aware off when it was working normally++++
-Power on
-No boot display (black screen/ monitor goes into power save)
-HDD light blinks once!!! and nothing more
-Press reset button (doesnt seem to do anything)
-Case fans and other fans all on.
-DVDs LEDs are showing busy as normal when power on.
-Left computer like this for 20 minutes to see if it would do anything but nothing happened.
-++Held in power button for 3 secs for manual shutdown then power on and still black screen.
-++Tried cutting power after turning on and then restoring AC mains and turning back on.
-++Cut power then held in power on button for 10 seconds to remove any charge in capacitors.
-Then powered back on still same problem.
-++Powered down then held Reset button in for five seconds
-Power on then message comes up on screen.
''BIOS error''
''Please Re-setting CPU frequency in CMOS''
''Please select BIOS profile''
-Default
-Profile1''
-When I select either or these two profiles then it I get the BIOS screen then windows 7 loads up ok and everything is fine until I do a shutdown but if I do a restart in windows it will boot up but a shutdown will bring me back to the same problem.
---------------Things I have done----------------
-Reflashed BIOS - no effect!
-Taken out memory and reseated it -no effect!
-Disconnected all Harddrives -no effect
-Taken out SLI'd graphics cards. - no effect!
-Checked PSU - voltage is normal
-Checked all connections and motherboard , no scarring or anything that shows a short.
-Air dusted the PC.
-When I manage to get into BIOS I tried Fail Safe defaults and Optimized Settings - no effect!
-----------------Things I havent done--------------
-Replacement CMOS battery (its the weekend cant get one)
-Tested components on another motherboard (dont have one).
-Reset CMOS/ Take out battery (dont think there is any point?)
-------
However now trying the technique I have done doesnt seem to work anymore so now I have a bricked PC at the moment.
Thankyou for your time!

Believe it or not, clearing the CMOS might actually help. Make sure you do it right by completely unplug the power cord or turn off the PSU, then take the battery out.
It also sounds like the CPU might be too hot. Look under the fan of the heatsink and see if there is any dust that will block the airflow. When the computer is on, touch the heatsink and feel if it is really warm. If it is really warm, it's a good sign, you might just need more airflow. If it is cold, you might need to reinstall the heatsink/apply new thermal compounds.
