I have cleard cmos but didn't seem to help, I have had this computer for about a year now.

Could it be the battery on the motherboard?

After powering it down completely and it began to post further I was able to get into setup and change the multiplyer to 7x but now it is froze again.

Also I got a check sum error

Finally got it to load windows but after a brief minute it flashed a blue screen with white text and then proceeded to reboot then froze again while posting. How irritating!

any one???

Should I flash the bios and how do I do this?

 

[dannaswolcott]

Do you have over clocking set for the CPU?

 

[dannaswolcott]

check your heat sink and fan it might be clogged causing your computer to freeze. Did you build the computer? Whats its brand?

 

[dannaswolcott]

If its not the heat sink or the fan, your motherboard, cpu, or memory may be going bad. But it sounds like a heat issue to me.
