OK so I pretty much need to build from scratch on a $300 budget. I replaced my psu months ago(Corsair 550w 80+ gold) and a few months later I suspected my cpu (Core i7 2600k) died based on the boot code displayed on the mobo. Bought a new Core i5 3470 of Amazon but the boot code persisted so surely it's the motherboard (GA-Z77X-UD3H). I need a new monitor(24 inch curved preferred) and new case for my hdds (4x3.5) and ssd(2.5 or 3.5 with adapter). And my gpu which is a MSI R7770. Any advice would be appreciated. Edit: mostly going to be used as a media server and some programming. Any gaming would be so light the on board gpu could probably handle it tbh.
