My computer is old, but still powerful, yet I have a problem where things are "just slow" regularly applications all freeze. Most noticeably, Chrome takes a measurable amount of time to update after input, but it happens to other programs too (I know Chrome is often resource hungry, but I don't seem to be hitting resource limits). For example, as I am typing this question, I tried to use the arrow keys on the keyboard to move back in the textbox to correct a typo and it takes a noticeable amount of time from when I press the arrow key until the cursor actually moves, so I often end up moving too far. Additionally, I can often type a full sentence before any of it will appear in the textbox. Every so often, every program will just stop responding completely, usually not more than 30 seconds, but sometimes for up to 10 minutes.
- Dell Precision Tower T7500
- 2x Intel Xeon X5550 (4c/8t, 2.66GHz, seen boosting to 2.9GHz, listed to 3.06GHz)
- 48 GB RAM (12x Kingston 9965447-001.A00LF 4GB 1RX8 DDR3-1333 PC3-10600 ECC Registered RDIMM)
- OS Disk: 2 TB RAID 1 (Dell 6/iR RAID controller) - I think Western Digital Blue disks
- Additional Disks: 256 GB Samsung SSD, 2x 500 GB Seagate HDDs
- Graphics Cards:
- Original: 2x ASUS GT 710
- Current: EVGA GTX 660 Superclocked, Quadro FX 3800
- Add-in USB3 card
- Windows 10 Education Edition
I have been watching the Performance tab in Task Manager and it doesn't seem like any specific resource is hitting limits. As I type this (with the issues mentioned above):
- CPU load: 15%-20% total, no thread shown over 75%
- RAM usage: 19.6/48 GB (even with 100 Chrome tabs open)
- Disk active time: 20% - 50%
- GPU Utilization: 0% - 5%
I have had this problem for a long time, but now I am working at home and can't get anything done. Things I have tried recently:
- Checked all drivers and firmware are up to date.
- Moved pagefile to separate HDD.
- Switched graphics cards from passively cooled to actively cooled (cards were running hot according to CoreTemp).
- Moved Chrome cache directories to SSD.
None of these have had a substantial impact on the problem. What else should I check?
