Pc not starting after I changed my CPU clock speed

title says it all, I changed my CPU clock speed in the bios from 200mHz to 230 mHz then restarted and now my screen shows nothing. THe lights are still flashing when I turn it on, but the screen shows nothing at all. Ive read from various sources that it would be safe to clock it a few mHz higher, but now theres this problem.

I would really appreciate some help as I have many assignments I need to get from it.

Thanks

You'll have to reset the BIOS to default settings. Most motherboard have a jumper position to do just that. Otherwise you need to take out the CMOS battery like said above.Gog

right thanks guys, I removed the CMOS battery like you guys said but still nothing on my screen.

I was wondering, do you have to take the CMOS battery out whilst the pc is running?

nope still nothing. Now im starting to get very worried, are there any detailed descriptions of alternative methods anyone can give me

A revision of whats wrong : I changed the clock speed of my CPU from 200mHz to 230mHz.......and now when I start my pc up it gives a constant beeping noise and nothing shows on my monitor.

check the beep code, or call the mobo manufac.Munkyman587

You'll see a jumper on the board like this, take it and move it over one and leave it there for acouple seconds then move it back. That'll reset it.

How old is this PC???

If it's something like a Pentium I or II, it's most likely not going to overlcock that well, if at all. Older PC's also didn't have great sensor readings and safety cut offs, so it is pretty likely that you killed it.

Also, a 30mhz OC on a 200mhz system is a 15% OC which is pretty big. If my memory serves me correctly, most OC's are done under the 10% range, and usually use special high end cooling. On the older PC's which ran hot enough on their stock coolers, OC'ing by that much might've very well bricked it.

nah im starting to lose hope, I cant find a jumper switch like that anywhere. Also my pc has a gigabyte P4 titan motherboard.

Does this mean that jumper switch will look different or non-existent at all? And is it located in the same area as shown on that pic?
