About a week ago I was playin a mmorpg and I heard a pop, then saw a sparq (instantly after pop). Not sure where the sparq came from honestly cause i didn't get a good look. Anyway, My old PSU is dead. Swapped in another 400w psu ..its a piece of junk iMicro 400w psu ...(PS-IM400).
Steps I took..
1) Put in the IM400 Power supply into old MoBo (biostar one). Barebones...plugged in my monitor into my onboard video. Powered everything up and nothing..no screen or anything. Seemed like I was gettin power...but just no video, and not seeing the Bios come up.
2)Added Sapphire 1950 vid card, everything would power up fine, then shut down ..again..no video ..no bios screen.
3) Changed CPU from my 3.4ghz to my old 2.1 celeron (both are socket 478). Nothing changed.
4) Bought a used MoBo for $35 that would work with what I have. No bios showing after rinse and repeating. Also when I plugged in just my Vid card and not my HDD...I would have power...but no screen showing. THe minute I plugged in my HDD together with my vid card...system would shut down after 5-10 seconds. No video, no bios screen.
5) About this time ...i'm starting to talk to my bleeping computer.
6)Took an old AGP vid card from a working computer...plugged it in..no video, no bios load up that I can see.
After all i've done..i'm runnin out of ideas...I mean, my first dead PSU is a 400w iMicro LC-8400BTX...and it seemed to run everything alright for about 2 years before it died. Now this newer im400psu from imicro can't run it?
My computer is an ol Betsy..
3.4ghz intel processor.
Abit VT7 motherboard (first motherboard was a p4m80-m4 by Biostar).
Sapphire 1950GT vid card (i know this is psu hog).
2gb Crucial RAM Pc3200 DDR400.
Seagate HDD 250 or 300gb..normal IDE HD.
Zalman 2 Ball Bearing fan (giant air cooled fan)
Parts i've swapped...
512m pc3200 kingston RAM from working computer. (took out the 2 sticks of 1gb crucial ram to make sure that wasnt busted)
PNY GeForce 6200 from working computer.
It seems like when I have just the HDD plugged into the mobo with RAM and either CPU...the HDD is spinning..its doing something cause i can hear the initialization click sound...but I can't see anything lol. So I don't even know if i'm getting to bios or anything. I assume i'm not though. Since I should be seeing the post to bios with the 2nd vid card i used. Which makes this even more puzzling ...since that is not a PSU hog.
One note...The New PSU i'm using is 110v (you know with the 230/110v switch in the back).....the old PSU that I used is 115v on the back...(230/115). Would that make a difference? Frig i'm pullin my hair out. Need a cig.
