No nothing...I am screwed

I am having a huge problem... I took the heatsink off of my CPU in order to replace it and while it was off, I was on the ground to look inside the case and my foot hit the surge protecter, powering it on. The computer came on for about twenty seconds without the heatsink on the CPU and then shut off. I put the heatsink on properly and then attempted to turn the computer on, but the fans twirled for about half a second and then...nothing. There is a red light on at the top right of the Mobo, but I cannot find out what the light means...HELP!!!

Re: No nothing...I am screwed

You can buy another 754 socket Turion processor on ebay pretty cheap if you fried your CPU. I think my CPU is overheating/overheated, as mine will power on for like 20 to 5 seconds and just shut off.

Pull the cmos battery if nothing posts, put the battery back in after 30 sec., this may help your problem

Re: No nothing...I am screwed

I guess you have a real problem now! First of all never work on a pc without unplugging the power cord!! so you can avoid an accidental start-up of the pc. If (I think) it's a AMD cpu this can be overheat in very short time when not using the heat sink! Maybe the cpu is DEAD

Re: No nothing...I am screwed

The red light indicates that that the ATA bus is set up properly, (same goes for many SCSI controller cards). On some mainboards it represents memory modules being under current. If the CPU was and AMD, then it is most likely history. Intel had thermal throttling much earlier, so it most likely is still OK. If your motherboard speaker is present or a functioning one is connected, it should report a dead cpu by a number of beeps. Check the cpu orientation and/or seating. (make sure you did not damage the cpu ceramic core when installing the heatsink -that killes most athlon/duron and P3 socket cpus)

My computer keeps shutting down after a few minutes. I have replaced the powersupply as well as the cpu fan. I am being told now that it is the system/motherboard. Is that an accurate answer?

When the CPUoverheats it goes into thermal shutdown and will not boot up again until theCPU has cooled down.
The heat sink may be clogged with dust, which causes the CPU to overheat byreducing air circulation through the heat sink.When you replaced the CPU fan, did you put new thermal heatsink paste on the CPU/heatsink? If not then the CPU can overhest. Your computer fanmay be faulty and not spinning freely, in this case replace the fan.
Check the fan and heat sink assembly and remove the dust, loosen the dust anduse a can of compressed air to clear away the dust.

I have ASrock P4vm800,Prescott800,Pentium 4 Pro.But i need a help.When it is powered up nothing happenes except the system unit ligth up,& chassis font panel ligth is blinking Continously.Cpu fan...

There is a verity of things you can check & or replace. You mentioned the CPU fan is not turning. This is very very important.
This suggests possible CPU fan is defective. Average life span for a CPU fan is 5 years or 50,000 hours. Your MB uses Intel PGA socket 478. For a replacement heatsink & fan assembly open the link provided;
A new heatsink assembly will come with a new fan attached to the heatsink.
It should also come with new thermal past or thermal tape attached to the bottom of the heatsink assembly.

As to the front panel LED light blinking continuously.
If the LED light is red in color this means your primary hard disk drive is trying to load windows.
My suggestion is for you to replace the CPU heatsink assembly first.
No need to remove the CPU from its socket at this time.
If you never replaced the Heatsink & fan assembly watch the video included below;
Once completed your system should function correctly.
If it doesn't, post you’re finding here & I'll help you further.

Dell OYF 432 Motherboard won't boot. Starts to boot then trys again.

Try removing each ram stick one at a time,be sure to shut down the pc while removing/replacing memory. If that yields nothing,remove the cpu heatsink,clean it & apply new thermal grease. If that doesn't work, then the motherboard is done.

Intel D845EPI/D845GVSR

The battery is for CMOS, and only stores time and date, has nothing to do with checksum.

Sorry but you can't rig a cpu fan, you could just fry your cpu.

If the 20pin main power plug and you 12v atx power plug and plugged in correctly, and you cpu does not get hot within 30 seconds, you have probably fried it.

Sorry, but it sounds like there is nothing that can be done.

When ever you touch a motherboard, you are suppose to wear a anti-shock strap. You could wreck the board without one also.

Computer wont start(Plz Help me ) Added Much Detail as possiable

start by removing everything, ram, any cards plugged in, drives etc. Then try and boot it. If the issue is still present, shut it down and remove the heatsink and cpu. I have known CPU's to be jolted out of their sockets after an impact. Take the heatsink off, lift the lever and remove the cpu. Check that all the pins are still aligned and straighten any bent pins then refit the cpu and lock the lever down. Refit the heatsink making sure that the heat transfer pad or heatsink paste is still present and lock it down. Plug the power cords and front panel wiring back in and try and boot it. If it boots, shut down and refit each item you removed one at a time, booting in between each item. If the issue arises again, the last item you fitted is the culprit. If you can refit everything and boot the system up, lady luck is with you. If you still cannot get it to boot after refitting the cpu, replace the mainboard. Sorry but without special gear, locating a fault like this on a mainboard is a real pain..

Three are a couple things you can check/try. Remove the memory, (If you have more than one DIMM load only one). Boot the system. Try each dimm in turn one by one. If your board is old. I see three ISA slots on the board, so it's old. It is possible the thermal tap or thermal grease may have dried up. (This will cause your CPU to overheat & shut down). The grease is located between the heatsink assembly & the CPU. Remove the heatsink assembly. Take a clean rag with a little alcohol on it & wipe off all old thermal grease. (Care full, do not over soak the rag & do not scratch either surface, heatsink or CPU). Double check all connections while in the case. Try booting again. Most CPU fans last for 50,000Hrs or five years. If the steps above did not help, you may need a new heatsink assembly, this will come with a new fan. Lastly, if all of the above has not helped. Check the voltage of the cmos/bios battery. It should test 3volts DC. If it test under replace it. On the outside shot, if you have done all of the above try another known to be good power supply. (If your CPU was bad nothing would turn on, not even the fan).
Give it a once over!

Good luck lieutenant_1!

Asus p4s533 will not boot after replacing fan + heatsink

Try to remove the processor, then clear it with contact cleaner, then plugin it again..

There isn't beep : Processor, and long beep is memory..

Hopefully this be of some help/idea..

Instantly shutdown

This sounds like it could be a heat issue. When you're in windows, you're using the processor more than if it just sits idle in BIOS. Using your cpu creates more heat. Make sure there is no dust in the fan or the heatsink on the cpu. Also, remove the heatsink and clean the old thermal grease compound off the heatsink and cpu and reapply fresh thermal grease.

Hi, have you tried removing the CPU and using a Air Jet Spray can to clean all contact pins and pin holes? The problem sounds like a loose chip. So also check all on board chips are seated, including RAM chips. Air spray can be bought from most Computer stores. Goodluck mistyman

Your CPU may have a problem

Have you removed all memory, other cards and unhooked all other drives to see if a short exists there? With a 300W PS some other component may be pulling too much that the CPU can't start so it tells you the problem is with the CPU or The CPU its refering to is on the video card? Good Luck, Tim
