Very very odd black squares

Posted by: ErikL on 27 August 2004

When I move the mouse pointer around pages on this forum and every other website, I'm seeing black squares quickly flashing. What's causing this?

It's driving me craaaaaaaaazzzzzzyyyyyy. Eek

(Cue Fritz sarcasm...)

Ludwig,
I think you crazy cursor may well be a precursor to some rather nasty things about to happen on your (windows?) machine. Just last night my cursor started erratic movements across the screen then the machine slowed down to a slow walking pace, took and age to switch off and even longer to boot up.

I at last managed to boot and then;

(1) Dump data to CD.
(2) Set system restore point.
(3) Set for chkdisk on next reboot (lots of files needed fixing).
(4) Set another system restore point (booting a bit faster now).
(5) Defrag, this took an age but now most of the files are together (back to normal speed).
(6) Run full system antivirus / spyware checks (nothing found).
(7) Set another system restore point.

Now things are much quicker and slicker with the cursor back to normal.
If your cursor is still playing up then something may well need fixing.

No.

No SP2.

No erratic cursor.

This happens only while moving over text on a web page. The little LSD boxes trail my cursor by fractions of a second.

Roy,

whoa - bad move.

If the machine is acting very slow or unreliable, this probably points to a disc problem. This is why your chkdsk had to fix a lot of files.

The defrag has moved lots of files around, and every time it reads or writes it is likely that errors are introduced. Multiply this by several million reads & writes before the defrag completes, and you've now probably hugely multiplied your problem.

I know several friends who turned a few corrupt files into a completely un-bootable system this way.

BTW, I have found that most HD problems are caused by loose cables, either at the HD or the motherboard.

cheers, Martin

Martin, thanks for you thoughts but last night things were so bad I even went as far as to unwrap my kosker XP Home Edition disks plus the factory fresh driver and utility disks and contemplated a fresh install of the lot Red Face My machine must have guessed what I had planed so it booted and limped along for a while whill I (hope) fixed it. I have just looked again at the file system via chkdsk and after running for most of the day nothing is corrupted, bad or broken Smile and the kit rushes along as per normal. I think I'll look at the state of the file system every now and then just to keep an eye on things.

Thanks for your advice.

Alex, last week iirc someone discovered a worm that was running about net, sneeking onto machines, activating any attached web cam and sending the snaps back to base. Now considering the uses some folks have for their web cams that idea makes my blood run cold.

Since it's Win XP, take a look in "Event Viewer" (Start / Control Panel / Admin Tools / Event Viewer / System tab).

If you're getting read or write errors they will be recorded here. If so, back up your data & replace the disc ASAP.

cheers, Martin

P.S. same works in Win2K & WinNT.

Cha-ching! Apple and Netflix are keeping me in the posh lifestyle I'm used to. Smile Seriously, did you get a new computer and you're just having these problems, or is this an old machine.

cheers

Dan, I decided to hang onto my current (4 year old) PC until it craps out completely or until I get a promotion, win lotto, etc. PS- I'll probably get a Thinkpad or iBook when the time comes.
