I got up yesterday to find that every Word and Excel file on my PC is corrupted and cannot be accessed.
On top of this, when I open Youtube, whatever I open, I initially get video but then it goes to a blank white, page but audio stays on.
The computer shop locally says I either have a virus or my PC's hard drive is packing up, what does our esteemed community think?
Not good, I've also had that sinking feeling when my digital life suddenly evaporates.
Doubt it is a virus, they are rarely purely malicious and it is not ransomware by your account.
Hopefully you've not been targeted by someone who just wants to harass specific individuals, although such people do exist.
More likely it is a hardware problem, possibly something as simple as your power supply failing.
If not that, it gets more tricky. Fact that your video works briefly and then dies suggests that your graphics card is having problems. for some possibly external reason. Hence my power supply suggestion.
Corrupted files in Word and Excel may hopefully be because the graphics are not shown properly, rather than that your data is lost.
Do you have any backup? Also, do you have any anti virus installed? Windows Defender is free and works pretty well.
I use Malwarebytes and it has served me well for more than a decade.
In any case, you can verify whether your data is ok by moving the disk to another computer to have it read there.
If that fails, you have to rebuild what you had, not a fun project.
