CPU Overheating with blue screen

July 27, 2006 at 14:25:22
Specs: Win XP Home, P4 512
Problem: Installed Jetfighter 2015 PC game by Global Star Software with no install problems. Run game for less than 1 minute and computer crashes to "blue screen".
Restart, POST states "high CPU temp", after login, which is slow, check CPU and MB temp via Asus Probe monitoring software and CPU temp is around 70 to 75C while MB temp is about 40C, watch temps fall to idle at 55C - 60C for CPU and 38C for MB, ambient temp 28 - 30C. This problem occurres everytime I try to run this game, have not tried other games but suspect failure will occur.

History: A couple of months ago experienced "blue screen" shut down with POST High CPU Temp warning while running e-mail and internet surfing. Noticed higher noise level coming from fan. Determined noise was from CPU fan running very high speed. Case was in a computer desk slot, pulled case out of desk and put on top of desk, removed side panel and blew a lot of dust bunnies out of case and cleaned CPU fan with "canned" air spray. Startup system, idle temps for CPU and MB 50-60C and 32C respectively. No further shut downs due to temp issues but didn't run any games only internet and e-mail. Installed game and tried to run yesterday with resulting problem as described above. Removed side panel to check for more dust found none, blew it out any way, left side panel off and tried to run game again, resulting in "blue screen" failure again, left side panel off and restarted and system idles at CPU 55-65C. Have not check to see what is running in background yet but I think only my Virus protection program.

System: Win XP SP2
Case: AOPen QF50A
PSU: AOpen 300W 12V 13amp (yel)
MB: Asus P4PE-Li845EP
CPU: Intel Pentium P4 3.06 Mhz 533Mhz FSB with HT enabled
Ram 2 X 256 PC2700 333Mhz
Cooling: 1 rear 80MM case fan, running 3200-3800 RPM at idle
Stock HSF on CPU running 3500-4500 RPM when idle, goes to 5000 RPM for cooling
Video Card: Asus V8170 GeForce4 MX440 64 MB DDR
Drives: 2 CD Rom
1 80 GB Maxtor 7200 RPM HD
System Monitor: AsusProbe for P4PE with CPU temp shut down at 90C
System Vintage: built in 2003

Question: What should I be investigating and what steps do I take and how do I investigate. I have read a few posts in this problem area and have an idea to examine the following: assuming idle range CPU temp is abnormal, weak PSU and can't provide enough amps demanded by games, CPU damage from initial overheat, CPU HSF / paste replacement, inadequate casing cooling, high temp HD etc. Need advice on where to start and what can should/can be done by a novice computer hardware service person.

1st of all, you can't overheat a P4 to death...it's virtually impossible. It has built-in thermal protection ciruitry & will shutdown long before it will fry.

If you feel confident doing so, I recommend you remove the HSF & clean it thoroughly. Blow off all dust & remove all traces of the old thermal material. Also remove any traces of thermal material from the top of the CPU. Then apply a fresh layer of paste (whichever brand you prefer). Follow the Arctic Silver instructions regardless of the brand you use:

I take it that you would attack the HSF system first and not investigate a PSU or inadequate casing cooling configuration. Are you indicating that you don't believe that the other areas are my problem?

I am not confident with screwing around with the CPU so I will take it in to the experts but I want to be sure as I can be that this will solve the problem before I pay someone to do it for me.

I'm not 100% certain the HSF/thermal paste is the issue...it's just a guess. But if the HSF hasn't been removed in 3 years, it's very possible that the thermal material has deteriorated. Removing & reinstalling the heatsink isn't all that difficult...you just have to be careful.

Your PSU is barely adequate, but it's not the cause of your overheating problem. And your old video card definitely isn't a power hog & it doesn't depend on the +12v rail. The MX440/64MB definitely isn't a good gaming card though.

Most people prefer more than one case cooling fan, but with the one you have (presumably blowing outward?) plus the cooling that the PSU exhaust fan provides, it's probably sufficient. A good rule of thumb for the board temp is to keep it within 10C of the average room temp...but that can vary depending on placement of the board's temp sensor & accuracy of the hardware monitoring software. I'd say your board temp is in the ballpark.


- Pentium III 800MHz or faster
- 256 MB RAM
- DirectX 9 compatible Video Card with 64MB RAM (Ensure you have the latest
available drivers for your graphics card!)
- DirectX compatible Sound Card
- CD-ROM Drive, Keyboard, Mouse and Speakers
- 700 MB Free Hard Drive Space
- Win 98/Me/2000/Xp
- DirectX 9.0c (included on game CD)

The gaming requirements aren't all that steep, but your video card doesn't meet the minimum. It only supports up to DX7.

Do you think the old Video card could be contributing to the heating problem?

Perch the heating problem isnt your video card as stated by jam and others its DUST clogging the fins of your heatsink and the lack of cooling in your case you should have atleast one fan blowing in cool air at the front and one in the back sucking out hot air to keep a contious flow of air through the case. Remve the HS/F also and remove old thermal paste/grease and remove dust with hover or compressed air, add new thermall paste replace heatsink wallah overheating problem solved.
