Hello,I am working on a compaq presario for a friend and am stuck on whether the mobo or cpu is bad. It will not post at all and the screen stays blank. I cleared the cmos and got the startup screen. I entered the bios to see if it recognized the hdd and it froze. Now it wont post again. It has an Asus A8N-LA mobo with an Athlon 64 cpu. Any help is greatly appreciated! Thanks
Not quite, it can be a bad mobo if u are using the integrated graphics. I had an older AM2 motherboad that didn't go past POST and when I entered the bios it u would show vertical lines and froze. My problem was that the capacitors went bad and i simply changed them with new ones. Have a look inside the case, look for any lumps on the capacitors heads or check to see if they leaked out.
