Blank screen?

Ok so this morning I had some time to blow so I decided to see what old PC parts I had laying around. Well I had a WHOLE PC just in different parts, so I decided to assemble them and see what I had. Well all went together fine, it booted fine no issues. It booted into bios, so I went and played around with the clocking and what not then rebooted it to load in the OS. Well when I rebooted it all I keep getting is a blank black screen, what could this be? The motherboard is a ECS K7S5A with an AMD Duron 1.3
 
Probably you clocked too high then, or perhaps the pci/agp lock failed. Try clearing the CMOS jumper, and see what happens.
 
The AGP and PCI buses are linked together, and regulated in part by the speed of the FSB. Overclock the FSB, you also overclock the AGP slot (unless there's a lock in place), which causes instability pretty quickly and could cause your blank screen problems. I don't know about that board, some locks are automatic, some locks require you to up the bus setting from 66 to 67, some boards don't have them at all.

Have you reset the CMOS? Has that done anything?

Not yet I just got back from the Big E, I will be doing it as soon as I figure out my other issues with my parents PC :( AHH I just cant win today, but atleast the Big E was a blast
 
WOOHHOOOO I Finally got back onto CF. Ok I have another issue now................the dang thing wont turn. I plugged it in and no power at all :( I have no idea what happened it was powering with no issues and now it wont. Is there anyway I can test the PSU with say a Multimeter or something?
 
Put a multimeter on the 24 pin ATX cable and the 4 pin Vcore connector. I can't remember which pins to test (I think it's the yellow wires on the Vcore connector) but you should get 12 volts on them.

Thanks I'm going to do that after lunch I just went on google and found out what to do. I will post in a few
 
Ok, here is what you want to do.

1. Plug in the PSU
2. Unattach the motherboard connectors
3. Take a paper clip and stick one end in the green wire on the 24-pin connector, and the other end into a black wire.
4. Measure the voltages with a multimeter, with the one probe in colored wire, and the other in any black wire.
This is what you should get:
Yellow--12v
Orange--3.3v
Red-5v

OK here is the deal. I took the power supply out of the PC all together to test it. Here is the readings I got


Tested on AC setting (just for HA HA)
Yellow: 0.013V
Orange:0.014V
Red: 0.015V


Now the DC Setting Test
Yellow: 0.8V
Orange: 7.6v
Red: 2.0V


Ok so from the looks of it the PSU is dead, but why would it work then the next day not? Also I dont know if this helps or not, but when I plugged in the PSU for the test the fan didn't come on.

PSU model: HP DPS-200PB-89 G
PN: 0950-3374 REV:01

Tested 3 times and the exact same thing everytime. HMMM how would that happen?

1. Your PSU is majorly screwed
2. Your multimeter is screwed
3. You are testing the wrong things.

I doubt that it is 2 or 3, since those voltages shouldn't exist out of the PSU at all....so that only leaves one option.

Ah yes that's a nice guide. If you did exactly that, then all I can say is that your PSU is dead

Yup did everything to a T, so now I'm in the hunt for a cheap PSU that will work foe a ECS K7s5A

Yeah I really do think it is the PSU, because when I plugged it in the fan didn't turn on.
