Computer security problem at Marton in Warwickshire

Good morning, We are with a customer on the High Street at Marton in Warwickshire, we have been called out to look at a Packard Bell iMedia 2326 computer that is misbehaving, the Customer has reported that this Microsoft Windows 7 installed computer is working fine in safe mode, but fails in normal mode by giving a security centre error on start up, Control Alt Delete is having no effect and the machine is locking up with out warning.

Update: This after checking the registry and start up files, we looked for malware and checked the Heat sink and Fan on the Processor we found nothing untoward on the computer, we checked the Event Log and found the error “Parity error on Device Raid Port 0”, this is a problem with the hard drive we have attempted to do a recovery on the drive and it reached 13 % before the computer locked up, this lock up is being caused by a failing hard drive.

The customer has decided to get a new computer, as this one is about 4 years old now and we will recover the data at that point.
