CPU virus?

Hmm... Did you test the PSU? How you have ruled out that it's definitely not the PSU? It could be anything really, again, did you check the event viewer?

YES first thing tested BTW.
 
Could be motherboard, PSU, HDD, or excessive dust.

Clean up the system, make sure all fans are working (including PSU fan), replug all cables (molex, SATA), check the SMART info on the HDD, run Prime95 + FurMark.
 
So you haven't, not if you buy pre builts. Swap out the PSU, see if issue continue's. Ten plus years? I assue you leave the computer running all the time?

Yep it is a great PSU best I have ever had.
I do not normally leave my computer on all night but some times I do.
I just know that this TX850 is still working and flawlessly powering the current new rig I am on now, I am NOT having any issues whatsoever so........
 
For what it's worth I think it was probably the hard drive too...

It is the HDD I put it in did a check and there are 2 bad sectors it is going out.
 
2 bad sectors doesn't necessarily mean this happens. I have had drives with bad sectors on them which do not show this behavior. Perhaps it was luck, but, just throwing my anecdote in as well. Can you run something and have it reallocate and see if that stops it? It likely is the reason, but.. may as well double check, ehh?

Probably a weak connection.

@trickson ... years ago, I has a system start showing stability issues. Monitor would go blank then come back at random, desktop and in games, then the system started rebooting when it felt like it. I tried swapping EVERYTHING. The last thing I tried was a different PSU, and guess what... it was the PSU. ...There's more to the story than that, including the bad PSU taking out a motherboard with it.

Just FYI, don't rule it out. Run some more diagnostics on the HDD. You could have some flaky RAM too... I have had RAM go bad on me as well.
 
a volt meter will not tell you anything a volt meter does not load test and does not check for intermittent faults unless you have it on there WHILES Its crashing

dead hard drive is dead
 
Put a load on it while there is a volt meter attached and it load tests... Its the best we can do from home, really... All it does is show you the voltage is in spec, but, its more ammo to help target a more focused solution. ;)

Like anyone would voltage meter. how else?

A voltmeter will tell you the voltages but as OneMoar suggested, it does not test under a variety of realistic loads.

But also, typical voltmeters cannot test for excessive ripple and other anomalies that affect computer stability. This is done by a qualified technician using an oscilloscope or power supply analyzer - sophisticated (and expensive!) electronic test equipment requiring special training to operate, and a basic knowledge of electronics theory to understand the results. Therefore, conclusively testing a power supply is done in properly equipped electronics repair facilities.

This leaves for the normal user, swapping in a known good PSU, as suggested several times already.
 
But again, its the best we have at home and one more bullet in the clip to make an informed decision. Its not the end all admitedly, but hey, if there is anyone that can split a hair...........................
 
Frankly, at best, all a voltmeter can do is verify a PSU is bad. It cannot verify one is good. Most users have another computer, a friend or relative they can beg, borrow or steal a PSU from temporarily. This is a better option than spending money to replace a component that was not bad, just starving for good, clean stable power.

You say split a hair, I say being technically accurate - a necessity, IMO, in technical discussions where being a hair off can mean the difference between go and no go.
