I tried upgrading my processor but when I boot it gives me 1 short + 1 long beep (repeating on a black/blank screen). Which would be a memory problem according to the manual. Nothing wrong with my memory tho(?). When I put the old processor back; everything works fine.
This is my computer: http://www.manualslib.com/manual/435619/Hp-Pro-3120-Minitower-Pc.html?page=2#manual
I upgraded from E5500, 2-MB cache, 2.80 GHz to Q8400, 4-MB cache, 2.66 GHz
New thermal paste between changes and all that. The fan doesn't seem to run any faster than usual when I try to boot with the new processor.
I have 8gb RAM, Windows 7 64-bit. Hope I got all the info required down. I was really looking forward to this upgrade - now I'm just a sad panda. Hopefully someone can help?
Thanks in advance.
SOLUTION: So apparently this was a memory issue - the new cpu booted with one of my sticks (http://www.electrobyt.com/index.php?main_page=product_info&products_id=6129#.VpD5BFLlnyF) and that one only. No other combinations or singles of my sticks worked. I even tried different dimm-slots for everything.
