hi,
i got a problem here, that i suspect it is my motherboard problem.
the model is LeadTek K7NCR18G Pro
more detail here : http://www.leadtek.com.tw/eng/mainboard/specification.asp?pronameid=79&lineid=3&act=2
actually everything is alright, it boots well and everything seems normal.
however after letting it run for around 20 minutes, the system speakers starts beeping repeatedly and i guess it is CPU overheating. so i decided to open up the case and try to clean the motherboard. so after cleaning it with brush, i put the system back and turn it on.
and guess what! when i turn it on, the monitors didnt show any BIOS screen, i didnt hear the system speaker beeps (hardware checking)
i tried to reassemble everything 3 – 4 times. it nothing really change. 🙁
when i turn it on again, still didnt hear any system speaker beeps and no indication of BIOS screen.
the CPU fan, chipset fan, and power cable for CD-ROM, HD, works fine (has light indication, hardisk is running). i also tested the power supply on another system and it just work fine. so the conclusion is it the motherboard fault?
please advice. Thank you
