This is an economic build for a friend 2 ½ years ago. (Total cost was about $275.00)
Motherboard: ECS MCP61M-M3
CPU: AMD Phenom II X2 550 black edition 3.10 GHz
Memory: AData 4 GB X 2 = 8 GB total
Hard Drive: Seagate 500 GB SATA HD 7200/16MB/SATA-6G
Video Card: ZOTAC GT220 Synergy Edition 1 GB DDR3
Power Supply: Diablotek 400W
System Case: Diablotek (a small one)
3 days ago:
My friend was browsing the internet, clicked on a link. The monitor screen went dark, showing some lines of words, then there was no display at all. The machine was still running.
He turned off the computer by pressing the power button. He tried to turn it on again. Failed.
Last night:
I tried to turn on the computer by pressing the power button. All fans (power supply, CPU and video card) were running. No display (from either the video card or onboard VGA). The power indicator on the front panel was NOT lit. The indicator on the keyboard was off.
I replaced the hard drive with a brand new SSD. Same as above except that the power indicator on the front panel was blinking. Now the optical drives make some clicking noise.
I took out everything (except for the CPU which is much harder to take out with the fan installed) from the motherboard (power connectors, memory modules, optical drives, hard drive or SSD for now, video card, TV capture card, etc.), and put them all back. The result was the same as above.
Now I disconnect the CPU fan on purpose and turn on the power. Everything is the same as above. The weird thing is that the CPU heat sink is not even warm after a couple of minutes without the CPU fan blowing.
I suspect that the CPU is fried. But how can I tell? Did I do enough to prove it already? Is there anything else that could be bad? What went wrong? Why the computer could not start?
Thank you all for reading this post. All replies are greatly appreciated.
