HP Pavilion All in One stuck in a loop

[Shelle02]

Yesterday our main PC became stuck in a loop and I am trying to find out how to get any further. We had been using the PC with no issues and working on an excel document. Once finished, I attempted to access the internet to browse some websites and it froze. I tried to do a task manager to see if I could identify which program was holding it up (as we still had excel open, Mailwasher as well as Outlook in addition to the browser but nothing happened. Eventually after about an hour the screen went blue and a message from Windows stating there had been an error and it would attempt to fix (I cant remember everything it said). It then did 4 stages of a scan/fix which took about 30 minutes and then opened up the start screen as per normal.

We were able to open Outlook with no issues. I then went into the documents to check the work we had finished and then it stuck again. This time we finally got a message about CMOS checksum is invalid CMOS Reset (502) and the PC restarted. After this happened we get the initial screensaver but when we click to get to the log on screen nothing happens. I tried task manager again, nothing. In the end I shut the machine down to let it "rest" overnight. This morning, turned it on andwhen it eventually starts its the same thing. The screen saver is there but doesnt allow us to click to then log in.

So how do we get past this? Is this a hardware failure? Should we take it to an IT expert? The PC is just over 5 years but I dont know what specific model as I cannot find the paperwork (Dad has dementia and doesnt know where he has kept it). I just dont know what to do next 😞
