PC keeps dying?!?!?,

Hi there

My computer keeps dying and simply switching off, not shutting down just going off. Once it does this, to turn it on again I have to switch the power supply off for several minutes then switch the Power supply back on and then I can turn the PC on. It can stay on for a few hours but can also go off really quickly (like 30 mins).

It all started after I installed 2 sticks of 1gb (2gb total) of crucial memory into the motherboard. Since then its doen that, and when i connect my external hard drive (WD 160GB passport) it will go off even faster (maximum its been on when hard drive is connected is 10 minutes).

I have a 500W power supply, an asrock p4v88+ MB, 2.4ghz P4 processor, some old radeon 9000 and something graphics card, sound blaster audigy 2ZS, and 3gb of memory (2 x512 and 2 x 1gb).

Im suspecting its the power supply as the more power is drawn (ie from the external hard drive), the faster the PC goes off. Although this is just sheer intuition, I have no idea if i am right. Also i thought 500w was a lot of wattage, then again the power supply came with the case and is about 5 years old now.

I would really appreciate if someone could hep in this situation as its obstructing me from work and I am about to buy a new PSU and if that is not the problem, i would not like to waste money.

Thanks a lot

You could try the Microsoft Memory Diagnosics tool click here to rule out faulty RAM.

Have you checked that the HSF is fully tightened down.

psu's that come with cases are normally cheap to keep costs down. you can't go wrong getting a decent psu with the 80% + logo, it will save you on your electricity bill and you can use it in your next pc.
