Just wish to share with u guys about my problem last weekend. I've actually figured out the problem already however i just dont understand.
Well, the problem goes like this .
My pc was fine all the way, and im downloading torrent movie as usual. Just my routine pc as usual .
I came back from my lunch, my pc is still working fine. Then i shut down i go out for lunch for 30 minutes. When i come back, i wasnt able to startup my pc already. It hang/freeze at POST where it shown "press DEL to run setup". I press but its just freezing.
Here's what i diagnose :
1) Change other PSU. Result same.
2) tested with other VGA
3) tested with other ram
4)My HDD was at SATA1 slot. I tried on SATA2 resule same.
5)Tried at SATA3,4,5,6 able to login window, but CPU Usage is 100%. very very laggy
At last i dunno what problem and i bring to shop.
At last, finally, the technician manage to figured out .
Its actually my Network Card/NIC
problem. Thats the culpirit.
I just dont understand how could NIC be able to make pc unable boot up at post screen. And even cause 100% cpu usage ...
