Whats up with my roommates comp?

post #1 of 33
Thread Starter 
When plugged into the wall, the light on the back of the psu flashes (steady when working properly and on) but the comp does not start up at all. I tried the paperclip trick and the psu itself is working just fine.

His comp is pretty old, still running ddr ram even, and its a total pos but he doesnt care at all about looks or performance of comps nor does he do ANY kind of computer gaming so if we can get this running again instead of buying/building a new one he would be extremly happy.

What else can i do to narrow it down so I know what we can buy?


Oh, and no extra ddr ram to test with

If he's more than one stick of RAM then try using only one.

Does the HDD light come on.

Fans spin?

If nothing works then it might be impossible to test individual components due to DDR / old socket CPUs etc.

I already tried pulling one stick out, trying both slots, then trying the other stick in both slots and still the exact same thing.

and no nothing happens at all, its literally JUST that little green light in back of the psu.

How would I go about testing the other components individually?

Time for a new power supply. Blinking light means its usually dead. Is it a HP?

If the computer doesn't start up at all then it's not a ram issue, you're computer would start and tell you that you have a ram problem. What is the most logical is you need a new power supply and those are really cheap depending on how much power you need, they do tend to go bad just like alternators in your car. I'm judging that you only need like a 350 watt or 450 watt power supply depending on if you're using a decent video card.

I tested the psu with the paper clip trick, light immediately turned constant and fan and led came right on. Unless of course there is something Im missing with the trick

And he doesnt have a video card, on board video. 1 hdd, 1 dvd drive , 2 sticks of 512 ram, and thats everything, noit even an extra fan so he could prolly very very easily do with a 350

sounds like psu problem. 350 even sounds like overkill for an old system like that. but more power isn't bad

I dont know how to say this without sounding like an ass, but if the paperclip trick doesnt work can someone please tell me (or another way to test the psu) so i dont keep saying i already tested the psu?

it would be hard for us to determine the cause of the issue without messing with it a bit. at first glance it does seem like a psu issue. yet it seems like you think differently.

it will be hard to get old parts like that to test cpu, mobo, etc. therefore the answer that makes the most sense at the moment is a dead psu. it may give you a solid light, but not be putting enough power out to the system anymore. i have a computer im fixing right now that when plugged in mobo recieves power, and fans spin up for about 3 seconds before everything stopping and the power button showing orange. its just 1 blown cap in the psu. things happen.

don't bash on people trying to help you. we all think its the psu and they are relatively inexpensive.

i would go with This psu
also get A couple of these if he has ide drives
