Hi all

I have an old 166Mhz Pentium with 128 MB or RAM which I was using as a
Linux server and general play around box. I bought it while I was
living in the USA. I have now moved to South Africa. I finally got
around to getting all my computers set up and connected. On this box,
alas, I forgot to switch the power supply from US 110V to SA 220V.
Oops!

I assumed the power supply was fried. It would not come on at all,
totally dead. So I replaced it with a locally bought 300w power
supply. Well it now comes on. The fans are turning and the hard drive
light comes on. It seems to go through the boot process. But I have no
video at all. Not even during the BIOS stage of the system start.

The monitor is OK. tested it with another PC. I am not getting any
startup errors beeps. It appears to be posting. I just have no video
at all.

I replaced the video card, which is an AGP card, with another old
card. No luck. Tried an even older PCI video card. Still no luck.

I tried resetting the motherboard by holding the power button in for
60 seconds while the system was off. Is my motherboard fried?

Any suggestions?

Thanks in advance.

Harry

this does nothing but turn it off.

remove everything and start from scratch

PSU- video- 1 stick of ram-CPU

clearing (resetting mainboard) the cmos uses a jumper on the mainboard and or pulling the
wafer battery while the system is unplugged from the main.
