my computer keeps giving this error f1 to reboot and f2 for bios, or ctrl, alt, del., and then it tell me that GIMHO is compress. can someone help me how to fix this problem.

I have no idea what GIMHO is. My searches reveal nothing either. But I do know that F1 to Reboot and F2 for Setup typically means it cannot find a boot disk. Tell us more about your computer. When did this problem start?
