pc starts but no output to the monitor 1

[lawrenzo]

Here's the story,

My hard drive became faulty so I replace it, on reboot my bios showed that I had lost 128 mb of memory - I removed 1 128mb memory dimm from the slot and my system would start but no output to the display.

I replace the good 128mb of memory but I still had the same issue. I bought brand new memory that is the same and I still have this problem - Have I blown the motherboard?

please help

With both a harddrive going bad, now possible bad motherboard and memory - I'd start to wonder if it's the power supply that's putting out some bad voltages and causing failures.
