Dead Computer
his is everyone’s worst fear that when they go to start or continue some important work their Computer won’t even turn on. The motherboard is the computer and normally when the motherboard fails your computer basically becomes a very expensive ornament. Occasionally motherboards can partially fail and only one aspect stops working, like embedded video or audio. Either way, we would highly recommend a motherboard replacement, even if the motherboard has only partially failed it is very likely that a complete failure will follow shortly after. At NiwTech we can perform the full diagnosis in as little as 4 hours and if you go ahead with the repair, we can have your Computer back in working order in 24 working hours. All our replacement parts are OEM and come with a 12 month warranty. But what about all of your documents and photos?

Computer Disk
This problem is a horror to behold. Absolutely nobody wants this to happen at any time but it normally does when you have something highly important and time dependent to do. This normally means that your Hard Disk Drive (HDD) has become damaged. If you’re unsure and you think your HDD is playing up, some common signs that your HDD is about to die are:
- Your Computer is locked and unresponsive

- HDD error messages
- General start-up failures
- System BIOS can’t detect the HDD
- HDD doesn’t spin up
- Your system freezes

The issue with HDDs is that they are an older technology that has be surpassed by Solid-state drives (SSD) in newer computers. We would always recommend that you upgrade your HDD to an SSD. SSDs are much, much faster than their older HDD counterparts. SSDs are also less likely to fail as quickly because they do not contain moveable parts like HDDs. It sounds like a lot of work and a lot of hassle but they us do all the hard work for you. After our NiwTech experts have carried out a full diagnosis we will give you a quote that includes the recovery of all your data and placement of it on the new SSD.
