    Windows installer won't boot uefi although the hard drive is GPT

    Posted: 23 Jan 2021 11:00 AM PST

    So I want to download Windows on my new laptop, but when I'm booting from my flash memory Windows it says "Windows cannot be installed to this disk. The selected disk is not of the GPT partition style", so I turned the flash memory into GPT and now when I try to boot it uefi it opens bios, and when I boot it normally it won't open because legacy mode doesn't support GPT

    Problems with a laptop

    Posted: 23 Jan 2021 12:58 PM PST

    Hello, so as the title says, i have problems with my laptop. Its a lenovo legion y530. When i turn it on the Lenovo logo pops up, but the circle doesn't show up, after that it cuts to a text bar in the top left that says "checking media" and then it cuts to an intel UNDI screen, and says media test failure, check cable. If i have my internet cable plugged in it shows the start pxe over ipv4/6 and then the bad or missing pxe menu and/or prompt info. I have windows installed on my ssd. A few times before it booted, but froze, and hasn't done that since. Yesterday the laptop worked perfectly, but today it refuses to work as mentioned.

    I would like some help to fix this issue myself, or worst case, take it to a repair shop or replace parts.

    Thank you in advance.

    I'm suspecting 1 or more cores have died in my CPU

    Posted: 23 Jan 2021 04:51 AM PST

    I have a system that has been running stable for years with a mild overclock and good cooling which then degraded and stopped working with unusual circumstances.

    4790K, GA-Z97P-D3, 32 GB RAM, GTX 980

    After working fine for 4 years it began to not start up properly, often resetting a few seconds into the BIOS sequence before starting normally. Over the period of about a year, the number of resets it performed before starting correctly increased until it just would not start at all. It just went into a loop where it would start, and restart after a few seconds. The restarts seem to happen before any OS loads.

    Once started it seemed to be ok... it's just never started again that final time. I did the standard testing, but never got it working. So bought a new system.

    I've gone back again and re-investigated my old system.

    I took everything out of the system and started testing each component independently. I have other systems and components I can use to test and I was able to rule out the RAM, GPU, PSU as the issue, leaving the MB and CPU as the culprits.

    I got the computer to start again, but there would be roughly a 1 in 4 chance that was completely random.

    I assumed it was the MB, as far I'm aware a CPU is either working or it's dead and there's no in-between state.

    Today I managed to use another CPU in the same MB slot (Intel Pentium G3258 SR1V0) and it has worked flawlessly.. Which is almost conclusive proof it was my 4790K.....

    There's an outside chance that the more powerful 4790K uses certain traces on the MB, or power levels that make defects on the MB more evident, but that's picking at straws.

    So if it's the CPU, how come it works sometimes? This got me thinking that it's potentially a 1 or more cores that have died and that every time I restart the system a random core is picked as the "primary" one? (Clutching at straws here). Unfortunately I can't "disable" certain cores to test this in the BIOS.. I can only limit the number.

    I also noticed that the few times the 4790K booted into a bootable Linux diagnostic distro that it would complain about microcode?

    So to me, it's either 1 or more dead cores with at least 1 alive or something to do with microcode that is dead?

    RECAP:
    - System worked flawlessly for years with a mild overclock
    - PSU, RAM, GPU are known good
    - MB works flawlessly with a CPU from a different Intel family
    - System has a roughly 1 in 4 chance of starting and getting past the BIOS boot
    - Some bootable Linux system tools complain about microcode.
    - CMOS cleared several times and using different techniques
    - BIOS re-flashed with the latest BIOS

    Multiple instances of rundll32 in different locations. Could they be malicious? Ran 2 deep scans with AVG free, nothing came up.
