help needed about computers

well basically my computer started freezing and crashing, after reseting i was sometimes recieving a 'cpu overtemperature' message and some bleeps before the comp started to load windows, sometimes the computer took ages before it would do anything after switching off the power other times it loaded straight away.

before i got the cpu temperature message i thought the harddrive was over heating so i brought a harddrive fan which attaches directly to the hard drive and that didnt solve the problem then a couple of times later i saw the message so i brought a fan for the side of the case to blow extra air in and i replaced the heatsink and fan.

things improved after that the cpu temperature was running at 86 before i fitted the new stuff and after it was about 76 and the computer worked fine for about a week, then yesterday it crashed again so i turned the power off like i done before but now when i turn it back on nothing happens. all i get is the power light coming on nothing else at all

is there anyone that has had any problems like this before and if so how did you sort it with out having to buy a brand new computer any help is greatly appriciated

i take it your cpu is amd not intel?
and i think its poped
#2
did you use thermal paste?
#3
hi it is intel and the paste stuff was already applied to the heat sink when i recieved it

INTEL!!! its poped
#5
my pc shuts down at 48

Sounds to me like something has burned out maybe total cpu failure.
Try removing all your add on cards except graphics remove and re-fit your ram and cpu, also disconnect all your drives except the hd. let me know what happens.

temp are we talking c or f ?

Pentium 4 by any chance? I had the same problem with my laptop, in the end I had to UNDERclock it with some software called "RightMark CPU Clock Utility". Works a treat now. That fixed the overheating however it never got to the point of not turning on.

Is it a laptop or desktop?
#9
will give it a try and let u know wot happens
#10
its pentium 4 and a desktop
#11
Is the fan on CPU still working properly? They do attract a lot of dust which eventually slows them down and can even stop them completely. Give the fan and heat exchanger a good clean - might solve overheating problem.
#12
the fan on the cpu is new the old one was thick in dust and looked like it wasnt working properly. right disconnected the cd drive, removed and put back in the ram and done the same to the cpu and heatsink etc.

power back on and still nothing the fans are spinning but nothing else so there is power getting to the board but it just isnt booting
#13
IMO the cpu could be fried in my experience an overheating system will/boot run for so long b4 freezing or crashing. I can't recall a computer failing to boot at all. But then again if the MOBO has a built in safety mechanism it may be halting the system to try and prevent damage. Check and see if the fan on the heatsink is working. :thinking:
edit maybe MOBO failure, CPU's are quite robust years ago my then State of the art Cyrix system did the same as what yours is doing so i gave the cpu to a techie to check he said it was dead so i u/graded the mobo and cpu but when i tried the old cpu in the new MOBO it was working! (after i bounced it off a wall! the b@[email protected] never checked the cpu)

erm i dont know lol i just know i got it from 86 to 76 i think c maybe but not 100% sure
#15
yh the fan is spinning on the heatsink
#16
You might not have got fan and heatsink in right. Make sure heatsink is in contact with CPU. Did you put new heat paste in when you replaced fan and heatsink? If not, you could try that.

Otherwise, unless you have spare power supply, motherboard and CPU (it could be any of them or even a few other things) your best bet might be to take it down to your local PC repair shop tomorrow.

#18
the heatsink is definatly in contact with the cpu because the paste has been spread about that was on the heatsink when i got it. it does look a bit thin tho could that be the problem?

ideally would like to try the cheaper optionsb4 i take it to a shop
#19
Try resetting the bios - there will be a jumper near the battery on the motherboard, swap it over to 'the other' position for a few seconds then pop it back before turning the power on again...
#20
thats why i wanna try all other options first i dont wanna get ripped off any payout if i dont really need to

Might work if the MOBO or CPU is not fried and bios is halting the system.
#22
i havent got them jumpers on this board i was looking a couple of days ago, instead i took the battery out for about a minute

Hmm, that might not be long enough, especially if there is a retention capacitor. Do you know what the motherboard brand/model is?

When you reseat a heatsink you really need to remove the old thermal paste and apply new stuff for future info, most of them 'settle' and chemically alter when applied and don't work well if the heatsink is moved.
#24
yh its a asus p5s800-vm/s
#25
ive had this comp for about 3 yrs ish its a packard bell from currys

You sure it doesn't have the reset jumper? According to the manual it does: http://dlcdnet.asus.com/pub/ASUS/mb/socket775/P5S800-VM/e2419_p5s800-vm.pdf (section 1-9 on page 1-21)

Looks about 3 to 4 cm below the battery and should be silkscreened CLRTC1 :)
#27
well i took the battery out again for a bout 10 mins and still nothing is happening

ok switched that jumper over how long do i leave it for?
#30
See the picture above - take the battery out, switch jumper for about 10 seconds, put jumper back, put battery back, see if anything happens!
#31
ok read instructions properly and done as they said power is back on but still nothing is happening
#32
Like i said chances are MOBO dead or CPU is dead

Never mind, worth a try. Next thing to try would be disconnect everything except one stick of memory, take out all of the drives etc (including the power to them) and see if anything happens... If no joy try the other memory stick(s) if there are more than one, to rule out memory failure. Also make double sure that all both power leads to motherboard are connected (easy to forget about the P4 connector if you've taken it off!)

What bargainsurfer says is probably correct, although P4s have pretty good thermal-limiting failsafes and are designed to not break if a fan fails. (Although prolonged high-temperature use, as it sounds has been happening, will shorten their life considerably!)
#34
CPU's generally are very robust i have been running a P4 for almost 9 yrs got to admit though i also use an intel MOBO with intel thermal monitoring solution
#35
well i think it might be cpu that is dead by the looks of it, the motherboard still has its green light come on, i woulda thought that wouldn't be on if the mobo was dead

ivee tried as u said jah but still seems to be as dead as a dodo, i thought something would have come up on the screen if it was ram failure
#36
9 years?!

Lights on a motherboard or case lights are not a good measure of a motherboard's health imho.
#37
ah ok thnx for the info wat does imho mean?

abomination
9 years?!

Yep 9 yrs current specs:
1.5g p4
1.5gb RDRam
380GB HD
22x DVD RW
16x DVD R
Carp Graphics card
XP SP3
They just don't build em like they used to! too much Tin and not enough gold and copper makes circuits Carp
Originally Built by ADVENT and No Major Failures!
Great for the NET Cos i got my monies worth out of it if it dies i'll just chuck it in the bin!:-D

The paste should be as thin as possible, it's just there to fill in the gaps,

shaz3383

imho = in my humble opinion

The original problem sounded like just overheating caused by too much dust. The temperatures looked pretty high, old Pentium 4 Cs of ~5 years ago didn't like going over about 60°C but I don't know what the newer pentium Ds and pentium dual-cores are like, and 76°C is certainly within acceptible range for some processors (although still on the high side).

Systems that don't boot up can be caused by a few different things, the easiest way to troubleshoot that is to swap parts with working parts but that's often not an option. I would try it with only one stick of ram and then the other though.
