The computer running ok at the moment suggests that your cleaning has alleviated an overheating problem.

 

Is that the original HWMonitor screenshot or a new one?

 

It shows an overheating CPU and low voltage for the RAM, VIN0 and VIN1 should ideally be reading around 1.8V.

If everything is still running ok you could take a chance on continuing to use the Bestec PSU but myself personally I would swap in a known good brand asap.

OK. Thanks.  Any ideas of what PSU is compatible with my ASUS motherboard?

You mention that the present PSU is a Bestec ATX-300-122, is it possible that it could be Bestec ATX-300-12Z like the one here

 

Your MB has a 24 pin and a 4 pin ATX power supply for the CPU which is not a problem as most modern PSUs have connectors such as the 20+4 and 4+4 type which can be joined or separated to suit, the one thing that we do need you to check is to see if your case will accommodate a PSU that has an on/off switch, cheap brands like Bestec often do not and some older cases do not have an opening for the switch.

 

Your MB specs here

 

The least expensive, good quality PSU that I could find here

Yes, that looks like my Bestec PSU.

 

Thanks. No doubt the overheating did not help my motherboard and PC performance..

All of your hardware could have been damaged by the overheating be it caused by poor case cooling/dust build up, a dodgy PSU or a combination of both.

 

I would recommend that anyone that ever purchases a computer with such a poor brand of PSU such as Bestec replace it asap, these types of PSU are used by most OEM computer providers in order to keep costs down, people using a computer for nothing more than school or office type work may not notice a problem but if you play games or watch videos ect the load on the PSU and other hardware increases and so does the heat.

 

Before replacing the present PSU I would suggest that you get it tested if only to satisfy for yourself that it needs to be replaced.

 

NB: Don`t forget;

Just looking up reasonable priced PSU's -Corsair is a name that comes up often.  Will wait until after Christmas then check that the case space will take an on-off switch, and then upgrade.

Antec, Corsair, EVGA and Seasonic are my preference and I have no problem recommending any of them to others, Bronze rated as a minimum is a must btw.

 

The Seasonic at the link that I included in my reply #21 is what I recommend in this instance, one of if not the best brand of PSUs, has more than adequate power output/connections and is also the best price, two alternatives are Corsair 500W Builder Series CX 80+ Bronze or EVGA 500B 500W Power Supply

Your CPU is frying as the temp should not exceed 65°C, this can cause the type of problem that you are having and in turn a flaky PSU could be putting out too higher voltage.

 

Agreed maybe it is the problem, but also maybe when over time the paste starts to wear off making it hotter than usual. Arctic Silver compound is the best paste around that would keep it cool. Make sure your computer is clean with good air intake. Also yes a better PSU might be worth the go as OEM PSU's are made very badly. How long has this computer been owned for?
