Please help me, my PC screen colour had changed and I tried to fix it through troubleshooting but no good. When I went to reboot my PC, a black screen came up with the white writing on it then it went to a plain blue screen with nothing on it and that is as far as it got. Could this be from a virus or is it a hardware problem and how do I fix it.

Good follow-ups from and — both hardware and software deserve a short, ordered check so you can rule things out fast and give useful details back here. Below is a prioritized checklist you can run through; do each step only as far as you are comfortable, then report what you see (POST/BIOS access, fans/beeps, whether anything new was installed, GPU and RAM specs).

  • Power/basic checks: note any beep codes, whether fans and drive spin, and whether the motherboard/CPU posts (BIOS/UEFI screen appears). Those facts narrow the fault domain quickly.
  • Try an external boot: make a USB rescue stick (Windows or a Linux live USB) and boot from it. If the display and system run normally from that media, the problem is likely Windows or drivers rather than core hardware.
  • Offline malware scan: run a rescue scanner from the bootable media (Windows Defender Offline or a third-party rescue disk) to rule out infection before repairing files.
  • Disk and system-file repair from Recovery Command Prompt:
chkdsk /r C:
sfc /scannow

If you run from WinRE against an offline Windows, use the appropriate offbootdir/offwindir switches.

  • Memory and dump analysis: run MemTest86 for a few passes to test RAM. If Windows creates minidump files (C:\Windows\Minidump), those can identify failing drivers or modules.

If you want, tell us what you find at each step and we will recommend the next specific action (how to create a rescue USB, read a minidump, or prepare a MemTest86 USB).

Normally a blue screen (aka the blue screen of death or BSOD for short), is due to a RAM or graphics card issue.
What graphics card are you running, and how much RAM do you have?

I agree with Serunson, more than likely it is a driver conflict rather than a virus.. What do you mean that you already tried troubleshooting?

I suggest that you remove the last component you installed in your computer (If there was a recent component that you installed), and perhaps check your monitor and graphics card for any damage.
