I've always had to use the touchpad or the "up" arrow to move up and down the screen. Now I randomly get the "up/down arrow in a circle" icon that moves the screen faster as you move away from it, which I haven't had since I got it in 2008. In addition, the cursor will "grab" page edges, open links, and freeze up, all randomly. Also, highlighting text to copy is hit or miss.
Does it work OK with a mouse (ie. only flakey with the touchpad)?
It is a chore to open or switch to a different tab or window; usually I have to press Ctrl-Alt-Delete to do so, then frequently close out the series of them that I opened. In particular, closing out PDFs is very difficult.
Get MS'
process explorer utility (free). Take a gander into what processes are running.
Add memory, if practical. If it takes DDR2, that's relatively inexpensive, or I can probably dig up a 1GB stick-let. (Yup,
takes DDR2). 1GB is, practically, the least you want to run XP with, anymore.
Sometimes, no matter what I do, I can't access a button. For example, I figured I'd have to wipe the HD, so I bought a USB stick to put it on. The stick comes with software that needs to be installed before I can do anything else, and before I can install it I have to press the button stating I understand the EULA. I cannot click that button, so the stick is essentially useless.
You should
not have to install that software to use a USB stick. It'll show up as a drive in Windows Explorer, or My Computer.
I've gotten a few possible answers. First is that I have a bad hard drive; while possible, I would expect it to notify me when I do a defrag or run "Speccy". The other is that I've picked up some sort of virus, which seems more likely. I have the free version of AVG, which has turned up nothing. The larger program offers other services for the dollars, but apparently no more virus protection.
OK, let's see.
Ultimate Boot CD. Download the iso, burn it out to CD (or use
unetbootin to make a bootable usb stick using that same iso.) Boot it, run a RAM diagnostic from the main menu. Boot it again, run a hard disk diagnostic, either Seagate Seatools, or whatever manufacture's diagnostic is appropriate. My gut feeling is it isn't a RAM problem, as systems with bad ram are usually very flakey.
If those both pass, download the
AVG rescue cd iso. Burn to CD or make bootable usb stick. Boot off it, update off the Interwebz, and use it to do a virus scan.
If it comes through all that clean, ask, and I'll come up with something else to try.
