Well all the Benimur's suggestions are mine too. As Benimur is a good professional. Try this too: On the motherboard you can find a small coin sized battery (button cell). This serves as the backup of BIOS settings and system calender. Remove the battery, and short the leads with a screw driver or something... Then try to switch your machine on. If it works, just replace battery with a new one. Otherwise put it back and get your motherboard serviced. All the best.
Hi, There shouldn't be any problem. Normally it should work straight out once switched back to 115. I expect the PSU to be toast if it were the other way around 230 to 115 and not in your case of 115 to 230. In any case, it is possible that the motherboard plus other devices were affected but possibly also unlikely. The power supply would suffer the brunt of the voltage difference, switch off or get busted before it can cause damage to the motherboard. You can try switching it back and forth 115 to 230 a couple of times while unplug. Makes sure the last moving to 1125 be snap and you should hear an audible click (of locking in place). If after all tries and the unit still is dead, then you have no other option but to try and replace the PSU. Good luck and kind regards.
Based on all your post, it is now a PC problem.
You may want to try checking/verifying all your devices/components connected to the motherboard is good. Start with the video card and memory, Remove, clean the little gold contacts, re-insert and try.
You can try USB keyboard and mouse and a 4 port USB hub.

Try this, (with the slider in the right position)remove the power cord from the P.S. and push the power button for 5-10 seconds. This will usually dissipate built up charge on the system board and P.S.. Then plug it together and try it with the slider in the right position. Also, try unplugging everything except the MLB, to see if it will beep (post). If so, power down and plug things back in one at a time...

I was ready to buy a new psu so I had it out and pkg for shpmt. Then someone said by removeing it and replaceing it might cause it to work. So I made sure it was set on 115watts and reinstalled,,,it works BUT,,,system won't boot,,not even load Gateway much less Win.
So I have a psu but a black screen,,,NOTHING !
I just noticed that no lite was on the keyboard.
I tried caps lock,nothing,scroll and numeral lock,,nothing.
I set in a good pc and all is well. Monitor is good,keyboard and mouse ,good.
What do you make of this ??
I finally got the power supply to start up. cdrom tray works as do's the burner and I suppose the floppy all have power. No power to keyboard or mouse and black screen monitor
Read above to see how it all started. Help !
