I am desperate. I cannot get my PC to start up again. The power LED is flashing slowly constantly unless I unplug the power cord ( then it blinks 3 times and fades out). When I plug the cord in again.... slow flashing again. I have tried pressing the power button for several seconds while power cord is out and while in. I have tried the reset button. I have disconnected my UPS and ran straight from wall plug. All the same ...... still slow flashing. (about 2 seconds on, then 2 seconds off) This problem did show up some weeks ago and would happen now and then. Sollution was to disconnect power cable and wait a few seconds. Plug back in and the light would stay off. Then switch on.... fine. Now I cannot get the light to stop flashing or the PC to start up. Please help, my system was built to play CSS every day! I have AMD Athlon 64 3500+ CPU nForce4 mobo (MSI) 2 x 512 DDR400 ram NX6600 PCIe video card 160GB Sata2 hard drive Any ideas welcome, I promise feedback.
