Hi all,
My daughter asked me to look at her computer and at first the unit would not power up at all. There was a led in the power supply that illuminated but nothing occured when power switch enaged.
I disassembled the power supply and found one electrolytic cap open and others that were swelled and high resistance with cap wizard. I replaced 6 caps and I assume they were for the 5 volt side as they were all rated at 1000uf 10v.
After reassembly the unit fired up booted and worked fine for about a week. Now the power button illuminates, the ps fan, cpu fan and dvd door operate. There is no power to the keyboard, the monitor displays check input and it appears the unit is not booting. I cannot get anything to display on the monitor when attempting to boot to bios.
I suspect mother board but unsure if something else on the ps might have failed.
Any help in troubleshooting would be appreciated.
Thanks. Rfranzk.
