Advise needed regarding my rig

[PandaNom]

This is my current rig.

Processor: INTEL CORE I5-3470 SOCKET 1155 3.20 GHZ QUAD CORE PROCESSOR
Motherboard: ASROCK B75 PRO3-M
Graphic cards: AMD RADEON HD 7800
Memory: KINGSTON KVR1333D3N9 8GB MEMORY
Storage: WESTERN DIGITAL 3.5" SATA III 1TB BLUE 7200 RPM
Optical Drive: ASUS DRW-24D3ST SATA 24X
PSU: FSP RAIDER 450 NON MODULAR 450W
Casing: SHARKOON T28 USB 3.0 MID TOWER

I need some advise regarding my computer, as i'm still new to this diy scene.

I had this rig for almost 2 years, and I had some issues recently. Went to get a diagnose, and the person suspect either my motherboard or psu is spoilt. Still have warranty for these items, however, I'm actually thinking of upgrading them instead. Anyone can advise whether it's better to bring for warranty or should I look to get an upgrade? If so, what should I get? Thanks in advance.

What is your issue first?

when I turn on, the fans and lights will on, but windows wont start. then it will just off completely by itself, and the process repeats.

Got spare PSU?

Got spare PSU?

Don't have. That's why i can't find the exact problem

If you want, can bring down your rig to PC Care & Solution, #02-32, Sim Lim Square, and ask Nigel to lend you a spare PSU to test. Can also discuss upgrade options with him as well.

Seriously, must you use such words? I'm pretty sure there are other words which can be used.

Hmm i never heard of this brand FSP RAIDER 450 NON MODULAR 450W , btw i see most ppl get reputation brand like Corsair or seasonic , coolermaster. And i always get 600w at least to give more breathing space . like my $125 psu bought 3 years ago still going very strong , its worth it
