Specs: Windows XP
Hi. My PC wont get past the boot stage that says press F5 etc for set up, it doesnt get to the XP bit with the black background it just hangs are the WinFast bit. Also the USB ports don't work either so i cant press F5 or anything. ~This is weird, ive tried replugging the power leads, everything seems OK.
I don't know what to do.
Also, just before this it seemed to have power fluctuation problems, it would not boot at all, it was like intermititant power, allmost like it was being switched off and on every 3 seconds, i took out the power unit, cleaned it and put it back in and now i have this problem.

Can anyone help me?

Are you saying that your USB keyboard is not working, Have you tried using a ps/2 keyboard or is that an option. You need to be more specific as to what you are having trouble with or have plugged into the usb. As for the power look inside your computer and find the cable that is connected to you power button get a flash light and make sure it is properly connected to the mother board. Also check your cpu or processor fan and make sure it is not clogged up if so clean it because that could cause over heating, power failure and windows shutting off your computer because if the cpu over heats by default your computer and windows will shut off it's a built in protection against frying your Processor. Older PCs would just stay on and end up burning your Processor out.. Hope that helps..

But whatever you do not use alcohol to clean it with everyone says to use it but it is not recommended and may mess up your computer I only use cotton cue tips or a can of air those are the two safest methods. The air being number one.. But avoid powering on your computer right away I'm obsolete so I always count to 20 anyway before powering back on.. And really that is what the book says to do, it also says to never clean your computer fan but recommends your best option is to replace it.. Of course that was before they had cans of air. Anyway just be careful when cleaning your fan..
