Ok, this is what happened.
I did the test, nothing happened on the PSU. So figured it was dead.
I bought a PSU which my local computer tech said would be compatible. However, I noticed it doesn't fit(physically) It has a 1/0 switch and power plug and fan are on wrong side. He told me I could take it back if I try it out and doesn't work so I figured ,why not. So, I plugged in all the power supply connectors although I just let the PSU unit kind of sit in there without the lid closed and just plugged it in.
I didn't have keyboard or monitor hooked up so couldn't tell what if anything was loaded. Although all 4 lights on back (ABCD) were solid green. I plugged in monitor and it showed Windows XP floating across. But didn't go anywhere. I plugged in mouse and keyboard (just to see if I might get lucky). Mouse lit up and keyboard wouldn't. I then powered it down manually (didn't know any other way without keyboard). When I restarted this time, I got ABC lights green and D light was amber. All solid. And it only has the Dell logo floating across screen. ANd still no keyboard.
So, any ideas now? Also, Iknow I'm going to have to get a different PSU, so should I wait and get it (will have to order). Or any other suggestions at this point? THANK YOU all so much.
Since the above, I unhooked the connectors onthe hard drive and now replugged in keyboard. I now have keyboard and get a screen that only comes up for a second. If I hit control/alt/del.,I can get it to come up again for split second and some of the things it says are:
fixed disk 0 ST340016A
Ultra DMA mode ATA/ 100
detected keyboard and mouse
cmos : no date time
hit del to enter set up (but doesn't work)
press F12 if you want to see a boot menu, ( but tried it and it doesn't go anywhere.)
It has some specifics about the system, (just saying that it is a pentium 4, BIOS version A05)
