Hey, thanks for using the forums, Can you tell me more about the problem? I could also use any serial or model number that may be found on the back or side of the computer casing, and also tell about how old the computer is since it was bought. Can you describe exactly how it acts? You say it freezes, but does the screen just sit there or does the computer shut off? Also are you able to skip going to BIOS and will it attempt to boot to the HDD? As it sounds right now with the information you have given me, it could be the motherboard, CPU, or the PSU. But a more exact description of the issue would help narrow it down. Also if you are able a picture of where it hangs up at may also help.

can you see if you system is displaying any of these errors. also attached is the manual for your computer, and also try to clear the CMOS



   

   

here is the manual to try to see what code your system is throwing. without more details it sounds like the motherboard is bad or the BIOS system is corrupted.
