Computer randomly freezes/ locks up

Hey,

recently I moved back to my house from university, and I have encountered a problem, where my computer will randomly freeze up for no apparent reason, not allowing any keyboard functions, mouse movement or any activity on the computer. It can be fixed with a hard restart of the computer (i.e. hold down power button) or it will automatically fix itself after around 3-4 minutes on average. I never had this problems whilst I was at university, but since I've moved home it does lockup around 4-6 times on average every day, at random intervals.

I have cleaned out the computer of dust, replaced the RAM cards into different holders, updated all drivers, scanned for viruses and checked the temperature of all components after running.

After abit of research I have a shortlist of problems and fixes could be, please can somebody give feedback/ opinions on what could be wrong (not saying it is any of these problems but just a few ideas).

- Graphics card being overworked, clock it to a lower setting/ higher setting.
- Hard-drive fault (HD tune)
- memtest86
- Returning BIOS/ CPU to stock settings.
- Faulty USB ports (Unplug unnecessary features, i.e; Ipod charger....)
- Faulty motherboard.
- Check again about something being lose/ broken components.

Any feedback is much appreciated and please ask if you need any more information!

Can you post your build list? - make and model of every component and Operating System

Have you returned your CPU and GPU back to stock frequencies and voltages yet? Do it NOW.

Probably a Power Supply issue - send your build.

Processor: Intel core i5-2400 @ 3.10GHz
8GB RAM
64 Bit windows 7
Graphics card: NVIDIA GeForce GT 630.
Model: Z68AP-D3 (Gigabyte)

Power supply I am putting a new plug in now, so we will see if that fixes it. Also, I am about to see if I can check the CPU and GPU frequencies and voltages to put them back to stock.

I think there is no need as I believe it was a power problem, replaced the power lead and have had no problems for approximately 8 hours now, so thank you very much for that suggestion!
