Puter freeze ups - paid for help - no go

Hello, I have a 4 year old Emachine. it is freezing up after 30 minutes of being on, internet or no. I paid for a repair store to resolve. They cant find the prob. I have unplugged all devices to rule out the problem child. I have run many programs to clean the system. No luck....any other ideas? As always..I thank you for your advice...afore my puter freezes up that is.

 

Hope they refunded your money since they didn't fix it.

If it freezes even when not being used...it sounds like some sort of heat related problem.

Do you have any software that will tell you the CPU temp?

Some of the computer guys should be around later....

 

They charged me an initial $55...and now they want another $58. They dont know what else to tell me.
After 30 minutes, the puter locks up in place. Ifn I wait for hours, it works good for another 30 minutes.
Ifn I reboot after the freeze, I get one of multiple screens...A blinking cursor, The Emachine logo, a note about a missing file (Windowsroot\system32\Hal.D?), a disc read error, a MBR error, missing boot agent, MTLDR is missing, files for Line 3419 cannot continue. ARRRGH! Can you help me? We re-loaded Windows with a saved back up file of my original Windows prior to taking to the puter fix it place.
Thank you!

 

First thing to check would be the power supply fan. It is usually visible from the back side of the pc next to where you plug the power cord in. If it's not spinning, that's your problem. You will also want to check the cpu fan, the one that sits right on top of the processor.

If you have a video card (other than one built in on the motherboard) check the fan on it as well.

It definitely sound like a heat related problem.
