It maybe the motherboard, but it may be the processor and power supply. Background. Abit KX7-333 Leadtek Geforce 4200ti Antec case and power supply. The one that slows the fan speed down when it is able. AMD 1800+ It is about 2 years old. Our power is constantly browning out and blowing fusses. We have bugged our manager about this and he always says he will have someone look into it. I have replaced the power supply to the PC once before. Also the motherboard always would warn of a low V-bat short after a start up. I replaced the battery and it didnt matter, so I disabled the alarm for it. After the power went out this week the PC wouldnt boot up properly. I would get to the bios screen and then the monitor would go to standby because of a lack of signal. I opened the case and noticed the fan on my video card doesnt spin anymore. I tried another video card and it didnt help. Sometimes I will get some strange bios beeps too. One long one and then sometimes a pause(3 seconds or so) and a beep, that repeats with the pause and the beep. But most of the time nothing just a blank screen. I took out the hard drive and tried in my old Dell and it boots up but then freaks out because it doesnt recognise it properly(old Intel 450mhz). Anyway, what do you think it is?? Power supply, Motherboard(mainboard), processor?? I was thinking it was motherboard, but was also thinking of just rebuilding a new machine(board and processor). Cant recall what kind of memory I have but it would be nice to keep it. 512 of it. What ever was the best matchup for a the motherboard. I think it was Pc2100 DDR. So my questions. Any idea what is wrong?? If it is F.U.B.A.R.(busted!!) what should I get?? Thanx TB'rs!!!
