What kind of computer do you have? Please list the specs.
how do you know its not the PSU?

the first thing to do when you turn on the computer is to listen to it.

Do you here the fans turning?...

I dont mind at all. I dont have all the answers and I need help just as much as the next one.

the video is integrated on the motherboard and there is no AGP slot. So I'm not sure that this computer will even support another video card. If you can find the option in the BIOS to disable the...

this sounds like it could be a hardware problem with the video card.
which compaq computer is it. I would like to look up the specs on it.

in the mean time
the first thing I would do is to...

that sounds like your video card on the computer has gone out.

what is your computer?

if the windows xp screen shows then you might be able to boot into safe mode by pressing F8 and the boot to Last Known Good Configuration. That would be the first step I would try before...

when you turn on a computer and it beeps continually, this usually means that a key on the keyboard is stuck. So the the first step would be to check the keyboard for any keys that might be stuck or...

after doing some research on your problem. it seems that the only way to clear a BIOS password for your laptop is to take it in to a Toshiba Authorized Service Provider.

also depending on the...

it's possible that you have a bad power supply. you could test it with a power supply tester. you can get one for about $20 or less. just count the pins on the main connector on the motherboard...

there are 4 lights on the back of the computer labled 1 2 3 4, check to see if they light up or not.

no operating system found means that Windows 98 was deleted from the computer. you can reinstall it if you have the Windows 98 install cd. This is not the recover cd.

I checked the dell website and it doesn't explain the lights on 1 and 4. check those lights again to see if 1 and 4 light up every time.

also did you make any changes to the computer (hardware...

does the computer give any beeps?

if its one stick of 512MB that wont work. thats to much RAM for one slot. you need two 256MB sticks. PC133 is correct. the beep codes according to the dell website seem to be a memory issue. if...

are you absolutely sure that you installed the correct RAM. Could you post which RAM you installed?

hi bigpaul,
I dont think the psu will make your computer freeze.

listen to it when you turn it on, does it make any beeps, that could give a clue as to whats wrong.

if no beeps and if you...

do you here any beeps when the computer boots up, and try a different monitor on the computer

ok, what exactly did you do to the computer? what type of computer is it?
Did you try to put everything back in the original configuration.

you should realy start a new thread and then some one will be able to help you. but it sounds like you might have a problem with the power supply.

na you should apply some themal paste it makes a difference. unless there is something else wrong with the computer, but the first step would be the termal paste.

whar does the BSOD say there may be a clue as to what is wrong.

did you put thermal paste between the heatsink and the CPU.

if you have a clean computer and the RAM proves to be good. then I would suspect the power supply next. it could be failing or you could have low voltage. check the power outlets and check any surge...

first thing is to check the power supply you can use a volt/ohm meter or a power supply tester. I like the power supply testers myself.

that sounds like the computer is over heating. make sure all the fans run, and check the CPU to see if the heat sink is clogged with dirt. you can clean the inside with a can of air.

the...

1. make sure the keyboard and mouse are in the correct ports.
2. try replacing the keyboard and mouse
if replacing the keyboard doesn't work you need a new motherboard

I have never personally experienced anything like that, but it sounds like it could be a power issue. If it is at all possible try to identify if the problem computers are plugged into the same...

AMEN Brother :)

if the other RAM you have is DDR2 800, DDR2 667, or DDR2 533 MHz DIMMs

then it should be the right RAM

its possible that the mobo is defective from the factory

first walk away from it and take a break

are you plugging into the same electrical outlet every time? maybe the issue is with the electrical outlet and not the computer.

also in a case like...

sounds like the mobo could have gone on to mobo heaven.
make sure the extra 4 pin connector is seated all the way.

you can try a different graphics card and you can try your monitor on a...

even if it works fine in safe mode it still could be the graphics card

its possible that this could be an issue with the graphics card. try a different monitor if you get the same screen then try a different graphics card.

ok start by putting the original RAM back the way it was. now with the HDD disconnected turn on the computer. does the monitor turn on and if does, does it say "no operating system found".

have you made any changes to your computer lately (downloads, install new software or hardware, delete anything) anything like that?

do you have your windows xp cd? you might be able to recover...

what kind of laptop is it

which windows version is it

what is the error on the blue screen

ok here's where it starts to get a little more complicated. both fans still turn when the computer dies tells you that the power supply "should" be ok, it would have to be tested to find out for...

it doesn't matter that its universal, you don't have the correct volts or amps.

well thats hard to say.
you have an under powered power supply
you have no ram and you have no keyboard

the only way to find out for sure is either take it in to a repair shop or buy the...

yes it needs to have ram installed. without ram installed the only thing that will happen is that the fans will turn on and thats it.

it will not go through POST
it will not beep
it wont do...

no ram = no boot

you have to have ram installed for it to boot
