Solved PC won't boot to desktop

So what I did was that I went into MSconfig and on the boot section I set the maximum RAM at 4000+ and the CPU cores to 2 ,I thought this would boost performance but it just bricked the PC. I tried going into safe mode but that didn't work either, so far my only option seems to be the command prompt but I don't know how to use it.

Do you have a "Repair" disk or the Windows installation disk to use for a recovery? http://www.eightforums.com/tutorials/2269-system-recovery-options-boot-windows-8-a.html

From the command Prompt, type bcdedit
Look for the Windows Boot Loader entry that contains an item named truncatememory
Note the identifier for that entry, it may be {default} or {current},
or a long GUID like {19a662d6-d972-11e3-847f-9663c71f16cb}
Type this command:
bcdedit /deletevalue identifier truncatememory
replacing identifier with the correct one you noted for that entry.

FYI, Those 2 fields should be left blank and only used for diagnostic purpose. Windows OS determines & uses the max cores and Memory as default.

Fixed, thanks for the advice.

PS: I messed with the settings because my PC was only using 1 out of 4 GBs of RAM.

You are welcome. Glad we could help.
