When you try to power it up now, does the whole computer not turn on? Or JUST the hard-drives?
You said there's a "pfft" noise, where is that comming from? Is the computer itself powering up, and just the hard-drive emitting a noise, then not powering up?
The most likely choice is power supply. You'd have to try it out with another - and if that means buying a new one, I'm sorry
Let us know how it works out,
I'm looking for a second opinion from the intelligent folks here...
I recently purchased from Tigerdirect.com parts for a new system.
I have a: Abit KV7 motherboard, AMD Athlon Xp 2900+ 400FSB Barton Core CPU, Ultra 512 MB DDRam, a case with power supply.
Let me note that I have built many (8) systems before. I put this one all together carefully and it powered up fine with my test harddrive. I unplugged the power, changed out the test harddrive for a good one, plugged it back it, and tried to turn on the power -- pfft. You can hear a pfft sound but no power. I tried using the test harddrive again and still no power. Both harddrives are good.
According to the motherboard website, I either have a bad power supply, CPU, or motherboard. I called Tigerdirect to get a replacement but after 3 tries they have still not sent me the postage labels they have promised. (This upsets me as I have reccomended no fewer than 5 people buy computers from them in the past 6 months. They have lost a very good customer -- I'll buy newegg from now on.) The case was very flimsy and I'm inclined to believe it is a bad power supply. Unfortunately none of my 2 pc's use the same type connector and I have been unable to test with the parts on hand.
My main question is this -- does anyone have any ideas on what else I can try besides buying new parts (starting with power supply and a new case -- the one I have for this system is truly horrible, I've already hand my hand sliced on a sharp edge that should not have been there.) and playing trial and error?
