Potentially upgrading

[Jano]

I'm starting to have a few issues with my pc - Windows not booting due to a dodgy sata connection on the Mobo, USB 3.0 has never worked... While these issues aren't really the end of the world as a wiggle of the sata cable fixes the boot issue and I don't really use any USB 3.0 items, I'm wondering if it's time to upgrade. I don't think theres been too much in the way of improvements in the last 4 years or so but I could be wrong. Anyway, the system currently is -

Corsair 600t, no need to change this.
ASRock Z68 Extreme4 Gen3 Intel Z68 (Socket 1155) DDR3 Motherboard
Intel Core i5-2500K 3.30GHz (Sandybridge) Socket LGA1155 Processor - Retail
two crucial SSD's, M4 128gb for Windows and programs, V4? I think 256gb for some games and a 2tb HDD for everything else.
Noctua NH-D14
EVGA SuperNova G2 1000W '80 Plus Gold' Modular Power Supply
XFX Radeon R9 290 DD Black Edition 4096MB GDDR5 PCI-Express Graphics Card (R9-290A-EDBD)
Corsair Vengeance LP 8GB (2x4GB) DDR3 PC3-12800 C9 1600MHz Dual Channel Kit x2
Asus Xonar Essense STX sound card
30 Inch HP Monitor

Can I use the processer with any of the new motherboards or do I need to upgrade that, same with the ram I guess. If I can get away with just changing the motherboard to something that actually works I'd be happy, performance of the rest of the kit is perfectly fine?

I've tried just about everything to get the USB's working, nothing happens at all when you connect something to them, it's been the same since I got the board. I can change the sata port but the only ones free at the moment at Marvell ones I think, which from what I've read are pretty poor?

Very occasional gaming is what its used for these days, nothing major at all, I just don't have the time.

Yea overclocked to 4.4ghz I think - it's a good 3 and a half, 4 years old so would be surprised if OCUK still stocked them.
