Desktop issues

by aryanmdt / June 15, 2009 10:19 PM PDT

Hi ,
I have been facing the following problem with my Desktop

1. Desktop gets switched off without any warnings. On starting after a abrupt shut down it I get a beep sound thrice and then a black screen with the following Message
?Your Desktop was shut down previously due to a thermal event(CPU Overheating) Press enter to restart?.
2. I switch on the comp but monitor signal comes up only after 2 or 3 minutes
3. The Comp gets hanged very frequently despite cleaning the comp of all spywares.

My desktop has the following configuration

3 GHz Intel Processor
Intel 915 GV Motherboard
512 Ram
80 Gb Sata Harddisk.

I have got the Desktop serviced from the best possible Comp solutions experts.

What they had to say was this

1. Intel 3Ghz processor and 915 commonly face this issue..Replace the Processor and use a 2.4 or 1.8 GHz processor.
2. A heat sensor on your mother board is not working properly get the Sensor replaced
3. This is an issue with the Capacitors on the mother board. Change the capacitors
4. You might have not used a heat sink. Make sure the paste between processor and heat sink is not dry..
5. Your Fan is not working .

I have tried almost everything I have replaced the paste between processor and processor and checked my fan both are working fine..Could you suggest a solution??

Those are good suggestions.

Short of replacing the motherboard which can be the most cost, I can bet it's a Socket 775 CPU so let's find that less taxing CPU. http://www.geeks.com/products_sc.asp?cat=961 Finds some 2 GHz models for about 50.

I've seen this issue and also seen people take it to shops to spend more money on repairs than what a new machine costs.

I have roughly the same system as you, Intel915PBL. I don't experience this problem so if that model has a known issue it hasn't appeared here. The tech comments cover much of what can go wrong on a older dated system. I suggest the following, but the cost maybe better spend on a new or replacement mtrbd. or system for that matter.

1) Get a better rated cpu fan/HSF setup, better than 3ghz
2) Use Arctic Silver as cpu paste
3) Inspect mtrbd. caps carefully check examples here:
4) Heat sensor bad or circuitry, replace mtrbd.
5) Cool the whole system better with added exhaust fan(s) and
if inlet fan if present is unclogged/clean
6) Verify *ALL* fans are working
7) CPU is already damaged(due to heat), replace cpu or system

Inspect and verify and be sure the system is clean of dust bunnies. If nothing seems to correct the problem, then any further cost is up to you. Some component is faltering and may be cost effective once its found due to the expense getting to that point.

Quick fix, remove side cover and place household fan to blow in, check results. Confirms heat issue if it runs a very long time or doesn't reboot. Also, be sure the cpu "overtemp setting" in bios isn't too low, use default value.

Firstly thank you for the reply.

I have tried all,The paste used is good,I have cleaned the fans,Even the mother board and processor has been replace by intel once.I'm pretty much done debugging the system.There is no solution except replacing processor and motherboard since getting it repaired will be expensive.

Have you tried

In reply to: Tried

reducing the processor speed (underclocking it)? It could be it's not exactly running it's actual speed. I would try setting it to run around say 2.4 - 2.6GHz.
