After Windows has booted and my desktop loads, my screen starts flashing every few seconds and if I click the mouse a few times I will hear a beep and then the whole system will just freeze.
If I press the restart button on the front of the computer, windows loads fine and the system works perfectly. I can then restart the computer using the normal method (using windows rather than the physical button at the front) as many times as I want and the problem wont happen again.
The problem only happens when I turn on the computer from cold.
If I turn on from cold, then press the restart button when I see the first boot text, then windows will boot fine and everything is ok. This is an adequate workaround (when I remember to do it) but I'd like to get this problem sorted if I can.
One thing I've noticed is that when I turn on from cold, the windows logo will appear with the green bar thing and when that disappears, the moniter goes a coupla shades of black like normal but the mouse curser will take an unusually long time (maybe 10 seconds) to appear. When I boot with the restart button method the curser only take a few seconds to appear.
I tried disabling all startup processes and that helped because I could actually get to my desktop, but as soon as I start using any application....the same problem arises.
I am beyond my own abilities to help myself so I humbly turn this issue over to this excellent forum and give many thanks in advance to anyone who responds as this is my work/business computer and I really want it running properly.
