I had a problem with my old HSF and I had to replace it. For some reason, it was not cooling the CPU enough, and as a result of that, it would obviously over heat after some time.
I went out and bought another CPU fan + HeatSink, and replaced my old one with it. However, when I put it in, made SURE it was plugged into the motherboard, I would start my computer and it would crash, making a series of system beeps(HIGH, then LOW, then HIGH, then LOW, etc). USUALLY it would ONLY happen when Windows XP was trying to start up. However, sometimes it would crash before it got that far.
I switched back to my OLD fan and it started Windows up without trouble. I switched BACK to the new fan, and it would crash again when Windows tried starting up.
I switched back and forth one more time to be SURE that I did not make a mistake.
My Motherboard is an Epox, and the fan I was trying to use says:
AMD Socket A Processors Intel Pentium III and Celeron Socket 370 Processors.
Would that work with a Pentium 4 Processor? If not, I guess the fan I got was a bad one. :/
One last point, however, is that the fan DID turn on when I turned on my computer. It just seems like my computer did not like it after some time...
Any help = Appreciated greatly.
