What's the issue with your Computer?

Some of the repairs and solutions are below. Please keep in mind there are multiple solutions to some issues and we will be completely transparent with your options and guide you through to a cost-effective repair for your Computer / Desktop PC!

Does not turn on?

In most cases, the power supply has become faulty in pre-built ones. If you’re building a PC, then something else may be amiss. Free Assessments.

No Display?

If the Computer turns on but there is no display on the screen, it could be a number of issues from a malfunctioning Graphics Card to a corrupted BIOS.

Windows Not Booting?

If your Computer is not booting, it could be a number of issues. Most common issue is a Hard Drive failure. But corrupted system files can be a cause too. Microsoft Windows Repair or Installation can resolve this issue.


A general maintenance is required for every Computer every year and half or two. Overheating can be a serious cause for damage to internal hardware.

Depending on the change made, it could even create more damage. But we have highly experienced technicians on stand-by. We can diagnose these complex issues with some of the latest diagnostic tools, and save time on the repair, where other service providers would be troubleshooting for a couple of hours before they find the fault
