I have an HP Pavilion e9110t and my issue is with my ATI Radeon HD 4650 graphics card. The stock fan on it died so I bought an Arctic Cooling Accelero L2 Pro to replace it. I've installed the new fan, however, after the first time I replaced the card, it didn't work and I got a "no signal" on the monitor. I took it out, adjusted the fan a little, make sure the connections were clean and replaced the card again. Now when I turn on the computer, it functions for about the first 30 seconds and then gives out again giving me no signal. Anyone have any ideas what's going on here?
