Hey guys,

Last week my Revo simply stopped working giving me a CMOS Checksum Error message right after I turn it on. (actually I beeps one time and after a second too more beeps)

It gets stuck Saying there is a CMOS Checksum Error. And asks to press F1 to load CMOS default values or DEL to enter in the BIOS. The problem is, the keyboard simply doesn't work. It detects the keyboard and mouse. Also detect the memory and hard disk but there is no way to make the keyboard work. I tried and bought a new USB keyboard and it didn't work. I've opened the computer and replaced the memory, bought a new CMOS (3 pin) battery which was really hard to find since I am in Brazil now but no luck. Computer stills stuck asking to press F1 or DEL. 

I read USB keyboards doesn't work if the CMOS are not loaded, only PS/2 keyboards but the REVO R3610 have only USB ports. I understand it's an old computer but I kept it in pristine condition so it's like new so I really want to fix it. 

I also tried the CLEAR CMOS jumper located on the motherboard but nothing happens. 

Please help me if you can, I will really appreciate that. ;)
