asuhdds Posted September 15, 2008 Share Posted September 15, 2008 Okay, so I bought a Dell Inspiron 518, then replaced the stock PSU with a VX450W Corsair and the 3450 GPU with a Radeon 4850. The problem is that, while before, when I pressed the power button with stock parts, the PC would boot up immediately. Now, when I press the power button, I have to hold the power button or press it multiple times to get it to start going. It's like the PC needs to get a running start in order to boot up. The fans start, then stop, then spin again and then it boots up normally. Sometimes it doesn't even boot however, and I have to just get lucky. When the computer does boot, it works perfectly fine, the PSU supplies power to the video card properly, even when stressed. It's just the bootup that's strange. Also, it seems to work better when I have the breaker switch off when the PC's off, then switch it on when I need to boot up. If I leave the breaker switch on after turning the PC off and leave it for several hours, the PC doesn't boot up as well if I press the power button (I have to press it 16 times or hold it for a long time). When I replace the stock parts, it boots up normal by just pressing the button once. I tried to short the power switch just now and it didn't boot up and did the stilted fan movement. The power switch is not the issue. Is it a motherboard issue not sending a signal the PSU can read? I wish I had another test system to see if the problem is with the PSU.
