unfortunately, yes.
The manufacturers can test for most errors but not all, if there is a clash with the kit you might need to change back to ps2/usb keyboard.

right ok well iv bought a new laser mouse and got rid of the wireless unit totally so now i have my g15 wired keyboard and a wireless mous still but its not a desktop package. I wouldnt have though its my keyboard as it is usb should i put the attahcment on it and make it ps2, but then wont that effect the features on the keyboard?. Any other suggestions on what i can do?

I don't know what effect it will have on the keyboard (nice one by the way), just give it a bash and see if it does stop the problem. How many other usb devices do you have on the system? The Kbd does look lik eit needs a fair amount of power.

I too feel I need to check the temps of my crashing computer--- What program did you use on yours?

Use speedfan
Download SpeedFan - Access temperature sensor in your computer

well iv only got 3 on it atm and thats my keyboard my mouse and my headset thats it. its still crashing and im getting really fed up with it now, iv had a friend that knows his **** have a look at my bios and he changed a few settings but still crashing. im really stuck for ideas now its really starting to get on my ****. i think it be a compatibility problem but i mean it will crash once and then itl be fine for the rest of the day. im really starting to give up with this **** now. feel like smashing the ******* thing up but iv spent too much money on it to do that. **** it.

Hi bego...the thing with these kind of crashes, as has been said before, is they are extremely hard to nail down. I highly doubt it's the USB causing the issues...I've never seen a logitech keyboard cause the computer to restart...unless it's a problem somewhere else in the computer.

So far, we've tested the memory - however, this isn't a sure fire test...as i've seen faulty memory that hasn't shown up with memtest...and it's pretty much the only program you can test it with. The next step would be Lebowski's first suggestion...power.

If your computer is receiving a bad power spike, it could be enough to restart the computer without even thinking twice. What brand powersupply do you have?

What we can do however, is try and find out what is causing your crashes.

Can you please goto System Properties -> Advanced -> Statup and Recovery Settings -> and uncheck the Automatically restart box.

Now make your computer crash. If what i think is happening IS happening, then you should now see a BSOD with a stop error. What is this stop error?
