Turn off the computer, Unplug the PSU, pull all cables and cards out of the system, disconnect the drives power connectors, leaving the CPU, CPU FAN, RAM installed.
Make sure the Power LED, Turbo LED, HDD LED, Sound, ReSet and Power connectors are plugged in correctly and not reversed.
Boot and see if you get the BIOS post boot info on your Display.
If not, rock ram back and forth in socket once.
Try again.
(something to consider:If not booting then install the ram in another system to make sure it did not get zapped some how, the same with the cpu. You should be able to take them to a local computer store (single shop not outlet) and they will probably check them for you.
)
If it does give you text error on the display or a tone error then you are getting to the bios without question.
With tone and video, then you vid card is fine.
With tone only, your video card is not functioning for some reason, try another.
The error should be something along the lines that the system could not find ROMBIOS of some such.
Shut down, insert ribbon cable and make sure it is not upside down, insert power cable.
Boot again and hit "ESC or DEL" and go into your CMOS settings and set the 1st drive to auto detect.
F10 to save and exit for reboot.
Should boot and see drive...
If not, install another drive as C that you know is good and the one in question as D.
Boot and enter into CMOS settings, set drive 2 to auto detect.
Boot again and see if it runs through identifying the new C drive correctly.
If not, your BIOS chip might be faulty, or the IDE port Channel 0 (1), which could be the port (socket) or the motherboard (doubtful)....
If the drive connects directly to the motherboard, purchase a secondary IDE Card and install it. I would suggest connecting to the second channel on the motherboard, but if one went bed the other is probably going to go bad also in short order.
..........
If the drive boots, add your cards one at a time and boot between each card added to make sure the system is not hosing up.
Also, if AGP, of VESA video, do not install a card in the PCI slot right below the Video card, the next slot down shares the buse and it can cause problems.
Another thing to look out for is NIC's and Sound cards, you might have to play card shuffle to get everything to play nice on the buse, but once it is done everything should be ok.
As far as throing it away only you can decide that, is it worth your time? and, is it worth you putting more money into if you find you need more than a battery?
