Computer locks up at POST screen, can you help?

Well... I just learned a very valuable lesson... Never trust a ';buddy'; when it comes to your computer... A ';buddy'; of mine came over while I was posting a message in another forum, trying to get some help with a problem I'm having upgrading my RAM... In the forum, I was getting assistance with my RAM timings and voltage, because those are things I've never dealt with before... Anyway, my friend read the entire thread and decided that he knew how to handle the situation, and he actually thought it was funny that I did not. Moron... He went in to setup, went into the DIMM control settings and changed ';CLOCK'; from ';BY SPD'; to either 166MHz or 200MHz (he can not remember which) and changed ';TIMING'; from ';MANUAL'; to ';TURBO';. Then he rebooted. When the screen came up that tells you to press DEL to enter setup or ESC to cancel POST, it froze up. I have tried rebooting about 20 times since then and it always freezes at that screen. I have tried changing the RAM, booting with the Startup Disk I made... I even tried removing the CMOS battery and waiting 2 minutes to replace it. I can not get into setup or anything else.

remove the cmos batter for longer around an hour also remove the power from the mains supply, then give it a tryComputer locks up at POST screen, can you help?
Did a smoke or something like that happened? Removing CMOS battery would have cleaned it but you said didn't so I suspect permanent damage. Did you do the battery-removal thing when the power is completely unplugged? If not do it that way.



And there is a CMOS CLR pin on the board usually, and usually it is a 3-pin array thing.
power own your pc without the cmos battery it will load with the default configuration
