I ask the experts on the web to please help me.
My old rig had a sempron 2800+ and a ECS N2U400-A mobo, after several restarts from overheating late at night I decided to fix it. I cleaned the dust off the heatsink and changed the thermal paste. Then I accidently seated the heatsink on backwards, Im sure this instantly killed my cpu but could it damage the mobo?
I ordered a replacement a sempron 3300+ and installed it but the computer still acts like it doesnt even have a cpu.
Fans spin, lights light, no Post, no video bios, and no beep codes.
Please speculate on weather the mobo is bad and/or if the cpu was DOA.
If the mobo is bad then did it just kill the shiny new cpu I just bought?
Please point out anything I may have overlooked?
Any advise is highly appreciated... |

Does your motherboard take up to a Sempron 3300+ (is it compatible with your current hardware?)

Thanks for the fast reply...
My mobo according to the website only takes up to sempron 2800+, but I belive that is because the 3000+, 3100+, and 3300+ were not produced enough to be listed as a common cpu. These models are rare and the 3300+ is simply a remarked Athlon XP 3200+ which my mobo supports. All a sempron 3300+ is a barton core with 400fsb and 512kb cache, I can see no reason why it shouldnt work. | |

Unknown CPU speed grades do not make the system fail to boot. (The core model and stepping is the same for those Semprons, so the CPU is not technically unknown to the board's BIOS.)
If you've fried a CPU in a fatal overheating situation, then chances are it's also killed the CPU voltage regulators in its final breath. | |

Oh no the old processor didnt die of overheating.
Simply by not having it very very tight, the mobo INSTANLY killed it. The death was quick and painless. Due to this design flaw I showed before. | |
