First I want to say hello . Ok here is what happened. I pulled out my video card to test it on other PC. The PC beeped and we assumed that it doesn't like my card. We put the original back in and it works perfectly. Now I go home to my computer and re-insert the card back in. I turned on the computer but the monitor didn't get out of "Power Saving Mode" and both LEDs for HDD and POWER were lighted. No beeps. The monitor is just black and it doesn't show the "Check Cable Signal" message when it's disconnected from the video card. I tried removing the RAM. No beeps. I haven't try to remove the BIOS battery. After that I tried to turn it on again. Both LEDs flashed again for a second and..... nothing. No fans were spinning. My LAN Card still blinks though. And the motherboard's LED is lighted, which leads me to believe that the power supply is kinda OK. So final problem is: It doesn't power on and when it was powering on it didn't start or beep. I think my power supply is fried (again), and I hope I didn't crapped my video card on that other PC. My video card: ATI Radeon Saphire 256MB 1650 X Pro AGP DDR3 Power Supply: Fortron Saga 450W Motherboard: Gigabyte CPU: Pentium 4 - 2.4 GHz Thanks in advance. I hope to fix this soon or my mother will kill me !
