I keep getting CMOS checksum error.

[The Reaper Wolf]

Yesterday I got a virus and It was really hard to get out so I decided to just upgrade and buy a boot ssd and a 1tb hard drive. When I took out the old one I put just the ssd in. I installed windows 10 on the ssd and it worked fine, then I turned it off and plugged in the hdd, when I tried to turn on my pc it gave me the error with the "CMOS checksum error" so I unplugged the hdd to see if it would boot normally but it didn't I have been unplugging and replugging all night and I cant fix it and also it freezes it when I get the Checksum error two options appear and I cant do click the options any more. Please Help I need this PC working by tomorrow Moring

Could be a flat CMOS battery. Thats the battery on the mobo. Replace it

Replace the CMOS battery, it's a CR2032, you can get them at stores like Walgreens or Rite Aide.
