Two PCs, one ‘big’, one ‘small’…….Both have recently developed the same problem.
They start up fine and are both reasonably quick to function (although I have noticed a slightly longer start up on the ‘big’ one than it used to be.
Windows, programs and folders open pretty quickly, plus the internet access is good as well.
Gradually, over a period of say one to four hours, the speed begins to decline, to the point where I am waiting for something to happen whether it’s a program or folder to open, or to access the internet.
The most obvious effect is when closing or minimizing a page, folder or window, the Desktop Icons / Shortcuts disappear and then slowly regenerate.
The ‘big’ one:
AMD Athlon 64 X2 Dual Core 4600+.
500G Hard drive (2 x 250, partitioned into 7 drives).
4G DDR2 RAM (3+ only recognised by Windows)
XP Pro SP2.
Office 2003 Basic. SP3
IE 6 (in a vain hope it was IE7]
The ‘small’ one: [Recently formatted and reloaded completely, but the problem returned]
Celeron 2.3 Ghz.
250 + 40G Hard drives (not partitioned)
1G RAM
XP Home
Office 2003 Basic SP3
IE 7
Both have Avast Anti Virus Home running, plus Prevx 2 installed and running.
Defender is installed but is partially disabled (only really used for info or to easily stop something from running).
I have maintained them as clean as I can (as far as I can, anyway) by regularly running CCleaner and ATF Cleaner.
There are 6 start up processes on the big one and four on the small one (different Graphics card).
Task Manager does not show anything much happening.
The big one when idle is running 0 – 1% CPU usage.
The small one 2-4% CPU usage.
Explorer.exe and svchost.exe appear to be the only ones that ‘kick off’ occasionally.
[I have tried the svc.host / Update.log fix from Microsoft on the small PC (for when svc.host.exe hogs the CPU at start up).....it helped on start up]
The two PCs are on a LAN via a Netgear Router (wired) and apart from Printer Sharing, there are two mapped drives on the big PC to the small one.
I have tried blocking all traffic by turning off File and Printer Sharing Firewall Exceptions, but no difference (back 'on' now).
Bearing in mind they were alright up until about a month ago, can anyone give me a clue as to what to do, please?
‘Big’ PC.
