I have a question about computer lag. My wife bought $200 Win boxes for our daughters. They take forever to load Windows 10, and forever to open any program. I mean any, across the board. I have cleaned them up as much as my limited knowledge would go, defrag, Malware, viruses, programs running in the background, programs that load on boot and uninstalled useless software, All to no avail, they still run like cold molasses.
They are so slow.....
(How slow are they?)
My grrls would rather use their Chromebook or phone.
What can I do?
A $200 new PC would mean it will be either a ATOM, Pentium, or Celeron Processor. Lets just say there is a reason why Apple does not use anything less than an Intel i5 (occasionally they use i3's in some models of the Mac mini's). Performance of those "Dollar Spot" processors are are dismal. When people ask me what to look for when buying a laptop, I always say at least a i5 or Ryzen 5 if you can afford it, and if you have to, i3 would work if it has a SSD (but I think pretty much all laptops have SSD's now anyways)
When I have a customer turn in a laptop and says its slow as molasses, the first thing I look for is what processor it has, and if its the above mention processor, I do the best I can for them. Usually cleaning bloatware. But if its a good processor, that is a sign that something more serious going on.
If it was a USED pc, then at that price point the issue may be CPU but most likely main culprit will be the hard drive. Windows 10 really needs a SSD. M2 preferred but upgrading an old system with SATA 7200 RPM hard drive to a SATA SSD the difference in performance is night and day. Windows 10 will constantly run a normal Hard Drive at 100% which will kill performance. Its a known problem with Windows 10.
Unfortunately it has to be said, MOST PC's are installed with Bloatware that kills the computers performance. It shouldn't have to be done, but as an IT person, this is the first thing I always do when I buy a computer.... after making sure the license is activated, get a USB disk with Windows install on it and wipe the Drive. Do a clean windows install. Remove all the junk that the manufacturer puts on the computer. Nothing kills a computers performance worse than McAfee and most computers Ive seen come with it installed and you can't simply uninstall it. This is one thing that APPLE does right (and some smaller PC Manufactures like Maingear too), they don't install bloatware.
Most of the computers we use at work at used 3rd gen i5's that we upgraded with SATA SSD's running Windows 10. Performance is fine for basic office work. For offices that need more power, we have more modern computers built with either Ryzen 7's or Intel's i7's. I also should mention, Windows 10 runs so much better on these older computers than the "current" version of Windows 7.
