I bought a custom built PC from a guy who had built it maybe 8 months before he sold it to me, and I have had it about 6 months now. Never had any issues with it up until a little while ago. I noticed it would randomly reboot with a frequency of maybe once a week, and there is a clicking noise that comes and goes.

I have swapped out my HDD with a brand new one and the clicking noise remains, so I have eliminated faulty HDD as the root cause of my problem.

Here is what my PC is made up of:

AMD Athlon II X3 440 3.0 GHz Socket AM3 with original fan and heat sink (4th core unlocked)
Asus M4A785TD-V EVO AMD 785G ATX Motherboard
Lite-On IHAS324 24X SATA Black DVD Writer Drive
750W Aywun MEGA POWER ECO Series A1-750E PSU
Kingston HyperX 2x2GB DDR3-1600 Kit CL9
Cooler Master Ammo 533 Black case
XFX HD-585X-ZAFV ATI HD 5850 1GB DDR5 PCI-E AVP Bundle (unsure if this is all part of the GFX card or not?)
Samsung SH-B123A Blu-ray/DVD drive
Intel SSD 320 Series 80GB
2TB Western Digital Caviar Green HDD
Wireless card

The last 3 items were things I added (replaced a 1TB HDD with a 2TB one and added the SSD).

So first question my PSU enough to handle all that?
Secondly, how does one tell what is wrong with their PC without replacing a whole bunch of parts? I can't afford to do that.

Thanks in advance for any advice!

I'd suspect the power supply. It should be powerful enough, but if it has been sitting close to the floor it will be clogged up with dust. If it's been close to a window the dust will have atracted moisture. The result is high voltage breakdown and then a reset. It is easy to open up and clean out the dust, especially if you have a compressor. Just leave it unplugged from the mains for 5 minutes before opening it up, to allow capacitors to discharge. That is where I would start.

You can never have enough Volvos!

Thanks Niel! I have a small USB vacuum cleaner on the way...should be able to clean it out.

Further information on the rebooting. I get this log from the event viewer, might be of some help:

I'd recommend you leave it unplugged for a fare while, a few hours at least. I've heard a few horror stories about people getting big jolts from the capacitors of unplugged power supplies. No hands on experience though so Niel may be totally right. Be careful though.

I put your'e system through a couple of PSU calculator's

They came up recommending around 435W so if you end up replacing your PSU I'd definitely go for a quality brand (find a particular model that gets good reviews) over just pure wattage. I haven't heard bad things about Aywun but there case/psu combos are normally really cheap.
