New power supply not working

by morph89 / April 15, 2012 9:28 AM PDT

My gaming pc stop functioning around july of '11, and hitting the power button caused fans and case lights to come on for about a second then immediately shutting off. Prior to this my internet browser (firefox at the time) was running slow and having weird issues where i couldn't read any text on the favorites drop down and it'd be all white, not being completely tech savvy i thought maybe a ram issue but alas my pc stopped powering on and i took it to my local pc repair shop. He told me that my power supply was dead and sent me right back out the door, so I picked up a new power supply around xmas time when i got money and tried installing it but the same issue, would power on for a split second then give me error codes on the mobo and not let me power on again until i reset the psu. I'm not really sure if the issue truly was the psu in the first place, or if its just the psu and maybe the new one i got is too low wattage, but I'd be grateful for some insight into this if anyone has any. Kinda broke so fingers crossed just a new psu will be the fix Silly thanks in advance for any help. PS sorry if I ramble on ><

Did you try it without the video card?

Same thing happens when I disconnected the video card except with a high pitched beep/squeal.

If all you did simply disconnect the video card with no other action, you will create an "error status" for the bios which reacts with a squeal and/or beep code. What you need to do is replace the video card with any other if possible. -OR- if you have on-board video re-activate it through the bios if you can.

What happens when a situation as yours occurs is to replace the PSU to hopefully resolve it as typical PSU issues are at fault. However, if the PSU may have taken down as it failed, there also the situation something else could also be at fault or become flaky or wonky. Power issues are hard to pinpoint as they are so basic and include everything. Thus, I suggest you reduce the PC to the most basic system it can be, disconnect non-needed devices, etc. just to see if it even remains ON but not necessarily bootable. Please do this, make basic system.

FYI- 8800 and 8600 based chipsets are video cards with known issues, so its possible on top of everything else it's part of the problem or multiple one.

That's a good sign.

That's a good sign you may have found the cause as it is no longer "immediately shutting off. "

The 8800 card didn't have a known issue but are now failing as they are in mid-life span. Some folk think this is a design flaw.
