|First thing to do is pull the hdd and either slave it to a working machine or install it in an external enclosure. You can then copy your stuff onto cd's, dvd's or another hdd.|
Once your stuff is safe, we can go to work on your computer.
Bad news is tech support was crappy when PC Club was alive and is nonexistant now. Good news is that they built their desktop machines with off the shelf parts...same stuff the end user could buy most anywhere.
So, if your power supply is dying or the heatsink fan ain't working, you just find a replacement.
You may need to do some detective work and look for manufacturer model numbers for the power supply, motherboard and any cards that are plugged into the motherboard. You should also have a driver disk for that thing if you bought it new.
The motherboard manufacturer and model will guide us to a manual that explains all the bios settings. The same info about the power supply will guide us to a replacement if necessary.
When you're looking around in there (unplugged from the wall - right?) see if you can locate a burned spot, melted wire insulation, or sniff out where the strongest burned odor exists.
"Also, on my screen it use to say:
Memory Clock: DDR 266
Memory Clock : DDR 333
Why is that?"
Sounds like the bios settings reverted to default settings somewhere along the line or someone changed the settings. Nothing to worry about right now.
See if you can access your hard drive and save your stuff first. We can decide what to do with the machine later.
Good luck Nia
