So you replaced the CMOS battery with a new one, to no avail. Did you check boot sequence?
Nothing happens when I push powerbuttom, and the light on the buttom is lighting orange instead of white.
there is a green light on the back of pc,and a orange on motherbroad.
I tried move RAM stick and put it back, nothing happened.
Then I tried with CMOS battery, it started without the battery, and even after I put it back.
Then a very confusing thing started to happen. every time I start it shortly after shut it down, it works perfect. But it's totally dead, when I try to start some hour after shuting down. I have to take out CMOS battery and put it back every time I try to start it, unless I start shortly after shuting down of couse.
It even works without pull off all plugs, just take out the battery and put it back, whala, pc is working.
Had replaced battery but problem remains.
In event logg I found a error message :
An error occurred while the provider of stored messages from the driver. Restart the Virtual Disk Service. hr = 80042505
What's causing this problem? Could it be BIOS? Should I try BIOS update?
