I've never had problems solving issues before, but this one has me stumped. Wifey has a Facebook machine. MSI B450i with Athlon 200GE, overcooled with a Wraith Stealth (no, seriously, have you ever seen the stock cooler for a 200GE? The Stealth is massive by comparison). Using onboard graphics, no GPU. 2x4GB Corsair LPX 2666, on default settings so 2133. Obviously no overclock on the little Athlon either. Cheap 240GB SSD - Adata I think, or something similar. 2TB Data spinner. It has been in an Antec ISK-110 until earlier today, vesa mounted to a 1080P Phillips VA panel. This rig has been unchanged for a year or more, worked perfectly until a few days ago. She started getting random freezes loading Facebook pages - particularly but not exclusively some of their flash based games - often, as in every couple of minutes. I've tried: Reinstalled Windows (10 Pro). Updated BIOS. Changed SSD's. Uninstalled and updated Chrome. Switched from Chrome back to Edge and back again. A dozen passes of Memtest via USB boot (passed no problem). Thorough clean of the system including reapplying TIM. Original TIM seemed fine. Still freezing. I was messing about under the desk yesterday and bumped the power brick. It exploded. Took out the internal PSU board in the ISK-110 along the way (I tried another power brick but nothing worked). OK, seems like I have found the issue right? Borrowed a different case and power supply from Akh-Horus. Its a shuttle, proprietary gear but it works. Proprietary PSU only has a 20 pin ATX connector but that's no big deal, using onboard graphics, low power CPU, only the couple of drives? CPU has 8 pin connector, no problems there. Fired it all up. Same issues!! Freezes after a couple of minutes max in Facebook. If I CTRL/ALT/DEL it will let me into the task manager, I close all instances of Chrome (multiple instances open, don't know why?) and reopen it again, but the same thing happens as soon as I try Facebook again. Note: I get the same behaviour if I use Edge instead. I was running the radio, on Chrome, an hour ago (ABC online) and it hard locked after about 3 minutes. I had coretemp open at the time, temps are in the 20's. Restarted, tried Facebook again, froze immediately. Closed all the Chrome instances again, and the radio has now been running for about an hour no problem. Open Facebook.. freezes again. My rig, albeit a much higher end machine, sitting next to hers is having no issues with Facebook, Chrome or anything else. Same Windows version, same Chrome version, same Flash version. Both connected wirelessly to router up till yesterday, I've even tried hooking her up to a LAN cable but that made no difference either. I don't know where to go from here. CPU? Motherboard? Fucking thing is driving me nuts. Any ideas?
