Windows XP won't boot up

Hi, i had shut down my one for the night and went to turn it back on in the morning and nothing. Power was on led light was green but, nothing. I thought it may have been the cmos battery but, it isn't. Tried switching the cmos battery for a new one didn't work. Tried to increase and toggle screen but, didn't work. I didn't upgrade the ram. Tried leaving battery and cmos battery out for 5 minutes. Any idea what this problem would be? Any help would be apriciated. Thanks.

 

reflash your bios

 

Thanks! reflashed the BIOS and it worked! I used macles technique and it worked. I used the bios 3304 though from via acer web site. I wanted to use 3305 but, i used 3304 and copy and paste the bios file name to the bios 3304 file and flased it. Thanks.

 

for future refernce for bios reflashing here is the site:

Follow macles instuctions exactly and you will hopefully be fine. Tekno.

 

Thanks if something like that happens to me too i will try this out
