My Computer is doing weird things

[Mobby Dick]

Hey guys,

so I got my pc a few years ago and never had any major issues, but a few weeks ago it started doing some things that made me think that there could be something worng with it.

So I always had the problem that my PC returned from standby all by himself, sometimes after just one minute, sometimes after an hour. But now this got even further. When I wake my PC up, it sometimes has to load the BIOS and takes as long as if it was completely turned off. But it doesn't stop there: it happened lot recently, that my PC goes into standby by himself. Not like autostandby, but while listening to music (via Spotify if that matters) and after different periods of time.

Did anyone of you experience similar things or do you have a way to fix it? I already scanned for malware (with Avira), but it couldn't find anything.

 

Thanks for your help
