I registered here a while back and forgot about this place however my new problem is most paritcularly strange and mind boggling.
First I will post my specs:
AMD Athlon X2 6000+ (no overclocking or other mod to it)
Gigabyte GA-M57 SLI S4 mobo
6 Gb PNY 1033mhz DDR2
2 x 1GB Gainward Bliss Golden Sample 8800GTS
900w Power Supply
Antec 1200 Case
As you can obviously tell my PC is for gaming/performance.
However this problem is more of a harassment at this point but I fear it may worsen.
About last week before going to bed after shutting down the PC, I cut the mains power to my system to stop the buzzing noise from my speaker system.
The next morning I woke up and when I went to turn my PC on all I got was activity inside the case (e.g. lights on, fans turning) but nothing on screen and eventually the screen goes back to power save mode.
I started pressing the reset button but that did nothing, I then did a power down (holding the power button in for 3 secs) and then power on but still same problem.
I then tried holding in the reset button for over 5 secs but that did nothing either.
Eventually I got round to solving it by quickly powering on my PC at the button then cutting the mains power. When I did that and repowered my machine the screen came back up and a message panel in Grey and White
something like this from what I can remember:
Please reset CPU frequency in CMOS
Then below there is a bar which could let me select to BIOS profiles which were
Default and Profile1
When I select either one of these my PC boots up fine and I get Windows 7 Ultimate 64 bit and I dont have any other problems.
However if i shut down my PC I will come back to the same problem.
I have checked all my physical connections inside and outside for possible shorts
Checked systems temps which are all normal during operation
After shutting down normally I tried powering on without any interruption in power supply but still go the same problem.
Checked my Mobo for any scarring (I have had the mobo for 3 years now but its in good condition and is maintained properly)
Reseated my Memory
Reseated my Graphics Cards
Checked my BIOS version its still the latest BETA but I have had it for 4 months with no problems.
Checked PSU levels which are fine.
I dont understand why Its telling me to check my CPU frequency in CMOS as I dont mess around with overclocking etc.
So in order to get my PC to work I have to power it on then quickly cut the whole power to it then turn it back on.
In all my history with computers I have never seen anything like this before and most forums havent
This is why I am turning to you guys for input and help!
Looking at someone similars problem I have a feeling it could be the CMOS battery?
