Debilitating errors with typing/clicking functionality

[Lucretz]

Ive been having problems recently with my desktop in that it has been randomly capitalizing my typed text.  This alone is very annoying but it isn"t a stand alone problem, since whenever this happens I also have several other annoying bugs:


_inability to send messages via msn
_ UNaBLe TO point and cliCK TO SELECT a SIngLE File/FOLDER as multipe file/folders will be selected with one click and similarly large blocks of text will be highlighted with a single click.
_ ClIckIng On A Link tHAt wouLd CAUSe A NEW pAge TO Open in the Current broWser window wiLL NOw CaUse A New window to PoP UP

I've ran several virus/malware scans using AVG, Spybot S&D and CCleaner which I run regularly and that has not seemed to fix anything so I don't think that this is a virus problem 

It was hard to even type this short post with minimal errors.  I've noticed that these problems won't start up immediately when I begin using my desktop but after an hour or so of typing  If i restart it will still bE PREseNt AfterWArd.  I"D really appreciate some kind of help as this is very frustrating

Did you make any hardware or software changes right before this started?

[Lucretz]

No I dont think ive made any significant changes to any hardware software for a while

[JJ 3000]

Have you tried doing a system restore to before the problem started?

When was the last time you blew the dust out of your computer with a can of compressed air?

[smeezekitty]

turn the computer off
unplug keyboard and mouse
plug them back in turn computer back on
and have you hot pluged PS/2 ?
i hope not
overheating is doubtful to cause that but download speedfan and report the temps

- No, I've never system restored, I don't really know what point I would have to go back to before this problem started.  I don't think I could anyway, since I use CCleaner and evidently that deletes your System Restore points?
- It's been a really long time, evidently.  I opened up my tower and blew it out and it was just insanely dusty.  I was shocked.  I did my keyboard and mouse while I was at it as well.

- I unplugged everything, when I disconnected my tower to clean it out.
- I didn't know what 'hotplugging' meant so I had to look it up.  Plugging in your keyboard after starting Windows?  No, it's always plugged in and I've never really yanked it out/plugged it in without shutting down first. 
- Okay, I installed SpeedFan.  I'll post the main readings:

GPU: 55C 
Temp1: 40C 
Temp2: 48C 
HD0: 33C
Temp 1: 48C
Core: 55C
Ambient: 0C

It's probably worth noting that GPU and Core both had a flame icon next to the temperature readout.

only 2 things left i can think of is
driver or some kind of teaseing malware

Have you cleaned your keyboard?

[Lucretz]

Yeah, I cleaned out the keyboard when I was doing the tower.  The keyboard was also fairly disgusting.  I'm going to feel really stupid if this incredibly irritating problem was a result of me not cleaning out my comp.  : u

So far, no problems after the cleaning, but they probably wouldn't of shown up by now even if they were still present.  I should know by tonight, after it's been actively running and I've been typing for a while.

You may have a faulty switch on one of your shift keys.  If it's still a problem try a new keyboard.

Let us know though.

Run sfc /scannow.......read through the website so you under stand the procedure.....sounds like there  are a few necessary files missing or corrupted....Have your XP disk at hand.....

i think its a hardware problem personaly

Could be.....but assume nothing......a check of system files won't hurt.

Could be.....but assume nothing......a check of system files won't hurt.

Absolutely.  That's what trouble shooting is all about.

[Lucretz]

One of the first things I did was try using a new keyboard, but the problem persisted, so I don't think that it would be a faulty switch.

I'm not going to have time tonight, but tomorrow afternoon I'll run sfc/scannow, and then post up what the results are. 

Thank you for all of the help so far.
