Startup problems

[davegl1234]

Hi, I recently built a pc and everything is going more or less fine except for a couple of issues, one of which I think must be a power supply problem.

Basically, when the pc is on there is no problems (except for one blue screen, but hopefully that was just a driver issue and sorted now). However, if i power it down for a while (say 30 minutes) i then have a lot of trouble powering it back up.

I think i've found a workaround by just powering down the psu for about 10 seconds and then rebooting, but still I would like to sort this out if possible, and also a little concerned I could be damaging other parts of the pc (is that likely?).

The power supply is a corsair TX 750W, and when I bought it I was told it was a good manufacturer and should be enough to power my pc...could this just be a faulty unit?

I think a blue screen i just received was due to a sound card driver issue (but didn't have time to get down all the message), but is it possible it could be also due to the power supply?

Cheers
Dave

What *exactly* do you mean by "i then have a lot of trouble powering it back up. "

Basically the power button doesn't reboot the pc. The fans may stutter and the LED on the fans light up for about 1/2 a second but nothing more. Once I have powered down the psu for 10 seconds or so it then starts fine. I am in the process of updating the bios which i'm hopeful will sort it out.

If you haven't already, try holding in the power button for a second or so.

Could be a bad power switch. Try the jumper method (touch the pins with a screwdriver, and see if it still has this issue). If this has no problems, replace the power switch. I recommend: http://www.frozencpu.com/
They should have everything you need.

Thanks for in the input, but the bios update actually sorted it out. Apparently this is a known problem with my board if it has 4GB of memory..don't really understand why but updating the bios sorted it.

Cheers anyhow
