ESP8266 esp-01 module does not start-up correctly

[michael_s8]

I have 2 of the esp-01 modules and both of them seem to have trouble starting in the same manor. This what I get in a continuous loop. any help would be appreciated. Like I said both my units do this. To even get this much I need to set CH_PD pin high. If I don't i don't even get this much.
