Hi,

My Dell Studio XPS 435T running Win7 Home Premium, SP1, 12GB has been rebooting at random times.

I posted in the security forum but the system is clean:

Can someone help with troubleshooting HW?

Thank you very much,

Joseph

Unzip downloaded file and double click on BlueScreenView.exe file to run the program.
When scanning is done, go Edit>Select All.
Go File>Save Selected Items, and save the report as BSOD.txt.
Open BSOD.txt in Notepad, copy all content, and paste it into your next reply.

You're seriously overheating:

Core #0 69 C (156 F) 65 C (148 F) 79 C (174 F)
Core #1 66 C (150 F) 65 C (148 F) 77 C (170 F)
Core #2 65 C (148 F) 64 C (147 F) 77 C (170 F)
Core #3 67 C (152 F) 65 C (148 F) 79 C (174 F)


Max temp for your CPU is listed at 67.9C

Start with opening the case, getting a can of compressed air (do NOT use anything else) and cleaning well inside, especially all fans and CPU housing.
With the case open, turn the computer on and see if all fans are running.
Do NOT use the computer in this state.

When done post new SIW report.

Wow, I had no idea.

Inside case wasn't too dusty.

All 3 fans run.

I cleaned with air.

What can I do?

What should core temps be?

Max temp for your CPU is listed at 67.9C

In an idle state it should be well below max temp.
How old is this computer?
You may need to reapply thermal paste.

Sorry, didn't see that.

Computer was manufactured (by Dell) end of 2009 (less than 2 years old).

Restarted and here's temps (with side case off) -- looks like cores 0, 1 and 3 already (5 minutes after reboot) already hit above-max temps, but now came down:

Intel Core i7 920
Temperatures
Core #0 53 C (127 F) 52 C (125 F) 69 C (156 F)
Core #1 50 C (121 F) 50 C (121 F) 70 C (157 F)
Core #2 49 C (120 F) 49 C (120 F) 64 C (147 F)
Core #3 50 C (121 F) 50 C (121 F) 72 C (161 F)

What are my options if temps rise?

Thanks,

Joseph

I don't know how to do that -- it is between CPU and fan?

Any other solutions?

Here is a manual: http://www.arcticsilver.com/instructions.htm, but......if you're not sure you can do it it may be a time to visit a shop.

Arctic Silver, right?

I can do it.

I just don't know if I have a 2nd gen i7 -- can you tell?

Also, can you point me to (or do you know off hand) the max core temps for a Intel Core 2 Quad 6600?

Thanks very much!

Great, thank you so much.

I've left the side panel off since blowing out the dust and the temp is holding between 49 and 56, with multiple apps open.

For now, you can even get a house fan and point it toward the open case.

You may try to install an extra fan as well.

Just ordered the thermal seal and 2 desk fans (120VAC, so as not to add to the burden of the PC PS).

Thanks again very much!
