Computer keeps rebooting

Ok this is really starting to tick me off, for the past week my computer will reboot on its own.

It will beep and a blue screen with text on it, then continues with rebooting (Can't read cause it flashes so fast, that if you blinked you probably wouldnt have seen the blue screen.)

and I have wasted 2 cd-rs because it will re-boot in the middle of a disc I was burning.

Plus about 5/10 times I start up my computer and my desktop loads, it will completly freeze the computer.

I don't think it's the CPU overheating, because I have the side open, and put my hand on the heatsink and it just feels a little warm.

Would it be a problem if I have a CRT monitor no less than 5 inches from the Computer tower? I mean this monitor has a Powerful Deguass, would that affect possibly the HDD and making windows act funny and force the computer to reboot?

Or could my motherboard be starting to die?
Or mabye the CPU is dieing?

Just a wild guess, but it sounds like you're running out of memory?

Try Control Panel > System > Advanced > Performance > Virtual Memory - Change > C: - System Managed Size

Oh, & if you have a secondary hard disk, then turn off the page file of C & turn it on on D:. That will speed things up, especially if it's on your second IDE bus.

Might be a memory problem. Sometimes you just install too many programs and too much is running on your computer. Try "FORMAT C:"

Could it be bad memory? Because I took out a 256mb of RAM out of a Computer they kept freezing at the Bios screen, or freeze whenever you try to install a OS on it.

But the computer gives me no warning saying im low on virtual Memory, so I will try some different virtual memory settings.

You aren't running out of memory. If that were true you would get warnings saying "Windows needs to make the page file bigger bla dee bla dee bluu". Usually your problem arises when:

1. The power supply can't keep up with your hardware
2. A chip on the motherboard is cracked
3. The parts can't disperse heat properly

So try this:

Open it up and blow all the dust yetis out with compressed air. A real compressor works best but you can use those pansy cans of air if you have to. Make sure you clean out the heatsink and fans and all the little sir inlet crevices. Then remove the powersupply and blow it out by blowing air through the fan exhaust or interior vent holes. A surprising amount of dust gathers in the PSU, which insulates the components, and like everything else the PSU hates heat. Try again.

If you're still getting problems, take your RAM out (after shutting down the computer of course), blow out the slots, and put it back in. Sometimes this helps. Make sure it's good RAM; if you pulled it from a PC that had problems maybe the memory itself was the problem.

If you're still having problems, try booting off a Live CD. If the problems go away, you should reinstall Windows. If they persist, you've got hardware issues. You could try unplugging non-essential parts like the CD drive and floppy drive (and any unnecessary USB devices) to lighten the load on the PSU, which will tell you if it can't handle your setup.

could be overheating or a powersupply problem. i would keep an eye on the temp and if you want find out what the voltage/amp specs on you lines are and pull out the multimeter and start double checking things (they wont be perfect but if your 12 volt line is like 7 volts theres a big problem).

That could be the problem too, because my DVD-rom drive was acting funny before it started doing this.

I mean I would have to eject the Disc a couple times before it read it correctly. Thanks I will try cleaning and see if anything is broken on the mobo.

Luckly I have an Air-compressor, now I have to drag my PC down into my basement lol.

Edit:My PSU just blew

, after I blew all the dust out that I could without opening it, I plugged it in and something sparked in the PSU and nothing works anymore.

Luckly I know where I can get an Extra PSU, but it will cost me a few bucks.

Man they need to stop upgrading CPUs for a while and figure out how to make a damn computer Dust proof, or at least makecircuits un affected by dust.
