Why is my computer so slow?

Specs: Lubuntu 14.04, Pentium 4 2.8 ghz
I have a computer lying around, with a Pentium 4 processor (2.8 GHz), 2 GB RAM, and a ATI Radeon graphics card. Now, the thing is, this computer is incredibly slow. Like, something has to be wrong with it. Now, I wonder, could it be that the CPU is overheated? It is SO slow, it can't even run Lubuntu properly. So what is wrong? Is the Pentium 4 so slow it isn't even able to run Lubuntu at a decent speed? It is weird, because I've used Windows XP and even Windows 7 on this computer previously, with no problems. And if it is overheated, what can I do to fix it?

Overheated CPU would just signal the temp control in BIOS and shutdown, similarly a burned out power supply does the same thing.

When is the last time you defragged?

How full is the Hard Drive?

What kind of programs are giving the most trouble?

I have never defragged - But it shouldn't matter, I've tried several harddrives but it is still slow as sh*t.

The harddrive isn't full at all. It is a fresh install of Windows 7 Professional. Task Manager shows 100% CPU usage just when trying to start a program like Paint.

Everyone.

Like Gopher said, overheating wouldn't really affect performance that much.

The Pentium 4 is a pretty terrible processor, even though it has a 2.8 GHz clock speed it is only single core.

"...I've used Windows XP and even Windows 7 on this computer previously..."

So, what have you changed since then?

Only some major hardware difference would cause this big of a performance hit on the same OS, though I'll admit I have a little trouble believing that this thing was ever able to run Win7 in the first place...

Could you give us the exact specs of the RAM, Mobo, GFX, etc.?

Though I doubt any of these going bad would cause poor performance, mostly just system instability.

And this is a totally clean install, with no programs yet?

I have changed the graphics card, but that's pretty much the only thing I've changed.

"overheating wouldn't really affect performance that much"

The P4 & pretty much all CPUs released since the P4 have built-in thermal protection circuitry. When the CPU reaches a certain pre-programmed 'trigger' temp, it will automatically throttle back in an attempt to lower the temp below that threshhold. So if your CPU is running hot & contantly throttling back, it will definitely affect performance. If the temp goes too high, the CPU will automatically shutdown to prevent itself from frying. This was especially a problem with the P4 Prescott which earned the nickname "hot potato". Make sure the heatsink & cooling fan are dust free & that the heatsink is installed securely & with the proper amount of thermal paste. It's extremely important that the proper amount is used AND that it's applied correctly. In the case of your P4, the 'middle dot method' is the way to go.

Please post the CPU temp.

riider: Thanks VERY much. Now I've realised this is probably the problem in my case. I've tried to find the processor temperature in the BIOS, with no success. However, I am now pretty sure this is what's wrong with this computer. I can try to buy thermal paste off eBay, and see how it works out. This processor should be able to handle tasks like reading e-mails, and watching YouTube. I'll give it a shot. Thanks.

If the BIOS doesn't list temps, try software such as real temp or hwmonitor. Also, you can get thermal paste at Radio Shack for about $3-4. No need to pay twice as much (or more) for "silver" paste.
