7600GT overclocked a bit, now won't boot!

[doctoe2260]

Ok guys, think I may have buggered my graphics card. I had a play with Rivatuner and overclocked my card a pitiful 20mhz. Test came back ok. Shut PC down and now when I try to boot up it gets stuck at POST, just before the drives get detected. I can't even access the BIOS!!!! Can any1 help?
Is it possible to reset the card manually?

Any help gratefully recieved!

If you overclocked your GPU with rivatuner then the settings won't kick in until you boot into windows - so up until that point the card isn't overclocked...

Thanks dude, at least I know it isn't the clocking thats bust it. Maybe it's something else and it is coincidence that it happened while I was clocking.

Thanks

PROBLEM SOLVED! Nothing to do with graphics! I had my wifes MP3 player plugged in to USB port and PC didn't like booting with it in. Removed it and all is well. Currently sat at 620Mhz core and 1500Mhz mem! Yay!

Thanks guys

ACK! that is one I hate (happened to me a few times and even when I'm aware of it being the problem it still gives me a moments panic) ... and not always easy to catch onto...

Interesting, glad you got it sorted. Didn't really think a USB device could stop the machine even reaching the BIOS and failing POST.

Some BIOS have the ability to boot from USB devices and even recover the BIOS from them... so they initialise the device early on and it can lead to problems... same or similiar problem happens to me a lot with some USB devices if I leave them plugged in while booting into windows, between the logo screen and the logon screen the monitor will go black and never go any further until I unplug the device and hit reset... strangely it will just as often boot up fine with them in as it will lockup with them in.

My asus p5ld2 also gets stuck on my cardreader with an sd in it about 50% of the times, sometimes it goes fine, sometimes it just freezes, nothing fixes it but a manual reset, tbh got tired of this as manual resets also reset my bios for 1 boot, and thus my oc, I just plug out the cardreader untill its past ''detecting usb storage devices''.
