Do these System errors indicate avirus

I am having start up problems.I checked system information and under PROBLEM DEVICES I get the 3 messages as below in SYSTEM INFORMATION.Did a full AVAST system scan and put all problems shown in the vault
Do these messages mean anything that may help with my problem could they be virus related ?
Thanks banksiaman

My computer works OK except for start up.
It starts OK runs for 5 mins or so then goes to blue screen or keybrd etc freeze
I power down couple of mins start again restart windows all OK for rest of day
If I do not wait couple of mins .Ii willl stop at various stages before windows starts.If it stops in POST and I get contiuos tone then I have to wait 10 mins or so before I can start it.

As I said at the beginning once started the second time it runs no problems for the rest of the day
