[NAME]​ , glad to see you are moving forward with the upgrade plan.  You must prepare all upgrade parts and gathering all necessary resources prior to working on the system.  If you are performing sufficiently as suggested, all your issues will be resolved at once.  Carefully follow these guidance, instruction, and asking question if anything is unclear to you. The part list:  solid state drive, top case fan, front fan, and fan splitter.  Remove the current top case fan (92mm) and remove the metal plate from it.  Install the fan into the top front drive cage using 4 existing rubber mounts.  Note the airflow inward the system and toward the CPU with fan connector is exposed and accessible at the top of drive cage.Installing the newly purchased top case fan (120mm) to the top chassis using existing glide lock and screw.  A minor adjustment will be needed to center the fan perfectly with the vent opening.  Note the cable wiring is accessible for connection.Installing the newly purchased front case fan to lower front chassis using existing snap-in latch.  Note the fan cable wiring is accessible for connection.Connecting all fans to the splitter cable following the diagram for proper PWM function.  This splitter cable will allow all fans to function as the original fan and will adjust speed automatically to cool the CPU when commanded.  A 4-pin connector will be connected to motherboard fan header.  A master connector (left) will be connecting to top case fan.  Two slave connectors (right) will be connecting to both front fans.  Finally, SATA power connector will be connecting power supply, it will provide direct power to the fans and avoid damaging the fan header on motherboard from overdrawn power.
Processor: Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz 3.19 GHz Windows 10 Home, Version 22H2 OS Build 19045.3208  Three weeks ago, before an international trip, I started to have problems that gave rise to a BSOD. I made some changes that seemed to fix it, and did BIOS update, but upon return, they showed back up. I have experienced BSOD for the last 2 weeks. With the CPU getting too hot and a BSOD last week, I assumed I needed to replace the thermal grease, so I did. That helped the CPU A LOT, but problems persisted. I have tried turning certain 'unneeded programs off' and the like, but then I realized I can't really remember what all that entailed.  Recently, another BSOD showed up in the middle of a monster project. Uggh. This has included periods of high Disk usage ramping up and down continuously to 100% for EXTENDED periods at times, while at other times, everything is just fine. But I can't afford to wait around for the next BSOD to happen while working. Big No Bueno. As I have continued to find the issues with Troubleshooting and re-installs, when I log back in and check the Reliability Monitor, I continue to get "Stopped Working" in Critical Events for: On restart: Killer x Tend Utility Service --> KAPS.exe came and went as problematic On restart: IAStorDataSvc After sign in: IAStorlcon Other symptoms include the following. slow, sluggish Disk (Read/Write: average 5-15MB/S with some spikes) Mouse control: general functions very erratic, snippets & copy-n-paste very slow and problematic USB ports don't seem to be functioning correctly LONG wait times for booting up  Downloaded and ran MalwareBytes Pro, and only got some PUPS.  Finally, after re-flashing the latest BIOS, the latest Windows 10 update was successfully installed after 4-5 failures AND the KAPS.exe started to work after FINALLY getting one of the Killer driver sets to install (I think.... I'm a mess at this point). No 'WARNINGS' in last two days. My only positive so far.  Here's a typical day of me UNSUCCESSFULLY trying to fix the problem. I'm getting as unstable as my computer at this point. 🥴   Starting to think a System Reset is needed at this point, but now the computer is not even identifying External Hard Drive (USB), so I can't back up my data, and I don't feel confident in 'hoping' the files will be secure in the Reset.  I was hoping there would be a super cool technical genius that would help this Luddite get to system stability. All I can offer is beer and eternal consciousness on your deathbed for your help, but dang, I could sure use it.  Thanks!
