    Hi everyone,

    I have an Acer Aspire 5920 with Windows 10 x64. I'm going to say right off that I am not experienced in swapping processors, but did what I thought was the right thing. I removed the battery and drained the laptop of power. I took out the old processor (T5450) and put in the "new" processor (T9300) and applied thermal grease and put the heatsink and fan back in place. I put everything else back in place and turned the laptop back on. It ran great for about five minutes, when suddenly I got a blue screen with a "WHEA_UNCORRECTABLE_ERROR" message. After that, the computer kept trying to restart itself. A few more messages popped up such as "CRITICAL_PROCESS_DIED".

    Thinking it might be an overheating issue, I turned the laptop off for a little while and turned it back on. From what I understand, this processor should run a little cooler, or at least the same temperatures. The computer booted sucsessfully again and I quickly went to HWiNFO to see the reported temps for the GPU and CPU, both were mid-30's. About ten seconds after running the program, the computer crashed again with the same errors. Could the reported temps be faulty, or is it something different wrong? The BIOS correctly identifies the CPU as T9300.

    I'm at a loss here. Thanks for any help offered!

    matthew88, download cmospwd and run cmospwd.exe -k to counter any BIOS errors. Reinstall Windows if it doesn't help.
