Thread: PC Hangs Up Frequently - Ok at Safe Mode

Hi,

Some peculiar things are happening to my PC. It hangs up frequently.
Operation System is XP2. It started from last two days only.

CPU fan is running properly. SMPS is working.

When I am starting in Safe Mode, PC is working fine.

Now I am really worried as when I am starting new setup of XP then also M\C is getting hang.

Any suggestion would be really nice.

Thanks in Advance.

i cant really figure out the problem, y dont u save all ur important data on an external HDD and re install ur OS ?

hangs up as in what? u get BlueScreenOfDeath?
might be problems in drivers, have u installed any new hardware as of lately?
try re-installing the OS.

Verify that the CPU fan is rotating at the proper RPM. U can use various utilities to find the exact RPM of the fan. Also do an online scan of your PC using Free Virus Scan - Kaspersky Lab

Thanks for Input

I think the problem is related to CPU fan Speed.
I am using AMD athlon 2400XP (Age: 4years +).

Can u guys give any input regarding the ideal fan speed for this CPU?

I have 5200FX graphics as well.

If u can do it, please dislodge the fan from the socket and try cleaning it. Dirt which has been accumulated all these years may hamper the ventilation and proper cooling by the heatsink. I guess the ideal RPM range has to be in between 3k rpm and 3.5k rpm.

Verify the fan of the GPU is also working fine.

Thanks

I am afraid that, that XFX card only have a Heat sink, but not any fan.

Anyway, Today i will try to clean that CPU. That's definitely a good idea.

In BIOS Fan Speed is showing as 4K+. Is that correct?

Dude if the fan is not spinning, the comp should re boot, not hang right ?
Well, if it is rebooting, apply some new thermal paste on the CPU too.

Fan speed is good. Just tell us ur CPU temps. I think its a problem with OS and u better reinstall it.Dont worry abt ur GFX card, older cards did not require a fan.

Well it starts with the symptoms mentioned by the original poster and with the passage of time the pc will stop booting as a preventive measure to the CPU from getting damaged. Besides he has also stated that the PC is working normally for sometime and then hangs abruptly.

I would also strongly recommend updating the GPU drivers.

also try to update to XP - SP3
further, clean all vents of ur cabinet and make sure that ur PC is in a well ventilated place.

CPU Temp is around 55 - 61 C.

The CPU temperature listed by u is quite normal for 2400XP. Hence we can exclude CPU overheating from the scene. Please verify the temperature of the GPU now, whether the fan is working properly and at the proper rpm.

Hi,

Yesterday night I have done that Heat Sink Cleaning for Processor. Tons of dust are there. Possibly fan speed is ok, but as dust are there, so air was not passing properly through heat sink.

Thanks For the idea.

Now to remove the heat sink, I had to remove the SMPS. From when I have re attached SMPS m\c is not starting.

When I click Power button, m\C just starts and just after starting it stops. Then I have to switch off the main power. wait for 1 sec. Switch on main power. Press Power button. Again just after starting, again stops.

I have tried several time. Same thing happens.

Please Help. I am not sure whether this is a SMPS problem or not.

Ok please verify all the other components like RAM GPU are properly kept firmly in their respective slots. It would be better if u remove them, clean them and reinsert them. If u are using two or more RAM modules, try starting the PC with one module only inserted and try it in all the slots.

I hope u havent dislodged the CPU, please verify whether it is properly slotted too.

I am wondering why u removed the SMPS/SMPS wires? The heat-sink combination can be dislodged easily without touching other peripherals.

All u have mentioned, I have already done those. Removing, cleaning all those staffs.

CPU is also OK. As m\c stops just after starting, I have to off main power switch. Other wise if I press PC power button again, nothing happens. That is why I am suspecting that it is a SMPS issue.

no... if your system runs ok in safe mode then it cant be a problem with the smps or ram. if provide some more details about ehre does your system exactly hangs - i mean on which screen ?

so far waht you have mentioned indicates that it is a problem with the win xp installation getting corrupt. try this first:

during boot time - coontinuosly keep pressing F8 - and select "last know good configuration that worked" ...

if this doesnt solve your problem - plz describe on which screen your system exactly hangs

Hi,

Actually that safe mode or m\c hang problem is solved.
Now I am facing a different problem.

When I click Power button, m\C just starts and just after starting it stops. Then I have to switch off the main power. wait for 1 sec. Switch on main power. Press Power button. Again just after starting, again stops.

And M\C is starting only for 0.5 - 1 sec.
That is why I am suspecting this is a SMPS problem.

just after starting it stops

plz explain this a bit. which screen do you see when it starts? does the monitor displays something? on which screen does it stops( gets turned off) ??

there are two possibilities here:

1) smsps problem
2) motherboard battery problem - this is more likely

plz explain a bit so that i can help you better

I have found the same in a couple of PCs. When we press the power button, the CPU fan starts rotating, but within 3 secs it stops rotating. Its as if the pc is turned off suddenly. Nothing is displayed on the screen.

@abcd_virus_007 Did u try switching on the PC without the RAM modules (just for troubleshooting purposes) ?

I have tried without RAM modules. I have two RAM. I have tried different permutations between slots and RAMs.

I think the probs with Batteries or SMPS. If it is with batteries, do you have any suggession.

@ Sourav: It stops even without displaying anything. Just as mentioned by "cool_techie_tvm" in his last post.

One more point is I have to switch off then switch on the main power to restart m\c. If I don't just nothing happens.

CR 2032 batteries are available in plenty at watch shops. It costs precisely 25/-. Maybe u can try with the newer batteries.

If u can, i would suggest taking the PC to some friend's house and trying to boot it with his SMPS. Its better to verify first before jumping straightaway for a new SMPS.

ya ... i have also experienced this problem on my own pc a few years ago and seen lot of my friends facing the same issue - a very common one

ram doesnt seem to be the culprit here - the cpu wont at all respond and two beep sounds on startup are the sure indications of the ram problem.he doesnt seem to get those beep sounds

@ abcd virus

simplest solution for you - open your battery from your motherboard - take it to any computer hardware shop/watch store and get a new one with similar tehnical specs .. it would hardly cost you - 10-15 bucks

if this doesnt work out - probably you will need to check the smps ..

Hi Guys,

Yesterday I have exchanged SMPS and Battery.

But after that M\C is starting. But no display is comming in Monitor.
I am very sure that monitor is OK. I have tried by resetting the BIOS.

Fan is running. Power is OK. But No display. Actually I can feel with "Speaker on" that just m\c is not running. That's why no signal is passing to Monitor.

Any clue guys. Please Suggest.

Thanks

Does the monitor display anything? I mean doesnt it even display the No Signal message?

Or the No signal message comes when u disconnect the monitor from the motherboard?

No every time it displays No Signal Msg. Whether M\C is on Or OFF
