So the other day I got a different processor to replace my Intel Pentium E2180, the processor I tried to install was the Intel Pentium 4 HT 630 3.00GHz. When I went to install it the pc kept turning off I moved the heat sink to get better cooling by spreading the paste even more, then it wouldn't turn on, kinda, everything powered on but the power buttons wouldn't work and the ports didn't work, I fitted my old cpu powered everything on made sure the bios was up to date then refitted the 630 but windows said something about how I'm trying to use a 32 bit processor in a 64 bit operating system. I looked around on quite a few sites and aparently it is 64 bit so I'm not sure why it didn't work.
I hope I make sense.
