Hey Guys
Im new to the forum and I need help on my HP Media Center m1090n. The problem is that I replaced the Ram from 1 gig to 2 gigs and then after I think the computer overheated and shut down on its own. So I thought it was a PSU issue so I replaced the PSU from 300 to a 480 watt and now when I try to boot the computer, it doesn't boot past the HP screen and the fan would go fast then slow and fast again in regular intervals. The thing is that when I apply pressure on the heatsink and push it into the CPU and hold it, it will start booting regularly into windows and everything is fine. I tried detecting the fan speed and CPU temp using fanspeed but it cant read it the temp unless I apply pressure on the heatsink like i did to boot my computer. I dont know whats causing this Im assuming its because my computer cant read the temperature but I dont know how to fix it.
