Hey guys, so I have an HTPC and the OS keeps getting corrupted to the point where a format and reinstall is the only option. Beginning of the year it happened first, then lately a few times and now it lasts a few days. I get failed to boot message and then no kind of repair/restore option works (I've tried them all) and an reinstall is the only option. This was happening on a fully updated version of Win 7 Home Premium. Last week I did a fresh install and immediately updated to windows 10. Same thing happened last night. I got the BAD_SYSTEM_CONFIG_INFO error and cannot repair using any method or get back into Windows (10 or 7).

I'm thinking it must be a hardware issue. Most of it is pretty old lol. The mobo, cpu, RAM and PSU are like 10 years old. The 3.5" HDDs are fairly old (but it does it with them unplugged anyway) and the SSD with the OS on it, and TV tuner card is also about 6 years old. The video card is almost brand new though. I've checked and rechecked that everything is seated properly, blown the dust out and checked all the cables.

Question is, although I probably need to replace most of the components (if I want to continue with this machine), which component(s) is most likely to be doing this? Also, I haven't updated the BIOS for a long time but it's probably unsupported now anyway.

Any thoughts? Cheers!
