Pc Overheat / Virus Problem

Over clocked CPU on hot day gaming......

Mmmmm time for a new CPU me thinks

Shouldn't be enough to kill it (my system has been running over clocked while gaming for many a hot day, besides few games stress CPU) .. Worst case should be a thermal shutdown. Unless you're being reckless with voltages.

Although I seem to remember this system having an over clock issue a few weeks back and the system was over volted?

It does depend alot on the cooling techniques/quantity and atmospherics.

I don't mess about with over clocking, but I'm sure I've read about disabling the temp sensor, if that happened the CPU wouldn't be able to slow down as it got hotter...

Core meltdown... nice and smelly :/
 
Ok guys, update!

I took my PC into work today and dismantled a PC to use the power supply from it. It plugged into my PC (just about) and fired up instantly to windows desktop!!

I had also put the i5 from my work PC in mine, but when I swapped it back to my own old i5 it still worked just the same, so I can confirm that the chip is OK.

So basically it looks like all I need is a new PSU.... so the question is back out there, can anyone recommend me one?

I believe I need one with a 6 pin and 6+2 pin PCI-E connector for my gfx card - as shown in this picture of the back of my gfx card - http://www.legitreviews.com/images/reviews/1086/XFX_4890_1GB_power.jpg

Thanks for all the help :D
 
^^ Any new aftermarket PSU is going to work fine, just make sure it's of a suitably high power rating for the system..... Which largely depends on the GFX card and the number of hard drives.
Overload the PSU and you'll soon have to replace it again.

I've had good experiences so far with Corsair and Akasa PSU's, but there's a tonne of choice.

Just bought a 750w Corsair Modular power supply from novatech

Good choice :) (PSUs can be a pain to diagnose if you don't have a spare one!)

I tend to only buy Corsair (or more specifically Seasonic/Flextronics/CWT rebrands which the Corsairs are). Ms arad85 has the CX430M in her shop server, I a few TX650s (which are being swapped out), and now a couple of AX series (replacing the TX as they are quieter)....

Glad you got it sorted though....
 
No problems.

I always find: http://www.realhardtechx.com/index_archivos/Page541.htm useful when looking at PSUs, who made them, and how they review. It's a useful page to bookmark somewhere...

PS to a comment above: unless you are running way more than average HDDs, the only thing you need to worry about is whether the PSU has enough connectors. Most HDs are 5-7W MAX....

Well it's the GFX cards really, some of them use stupid amounts of power, especially if they're stacked up in multiples.
I have 4 HDD's inside my case and 3 on e-sata, i'm not sure what average is? :p

There is of course one important thing that OP needs to remember here, "load balancing".

Don't connect everything to the same PSU output channel, try to load up similar devices evenly across each. Sure it won't look as nice with cables all over the shop, but it's probably the biggest cause of PSU failures i've so far come across.
A PSU might be 800w,but spread over (for example) 4 channels at 200w each, suddenly you can be overloading the PSU without getting anywhere near 800w, the GFX card should also have it's own supply with nothing else connected from that channel (if possible).

A lot of decent power supplies (e.g. the one the OP has bought) are single rail outputs....

The jury is still out on this, I don't like the idea of single rail supplies. Yes it removes the need for careful build, but there's a risk that if one thing goes down the pan, it could take everything else with it.

Basically using my last example with an 800w supply, if your total power is actually 600w, on single-rail it'd take another 200 before the supplies protection kicked in (that's quite a lot), but on multi-rail it would isolate the fault to just a few components and require much less overcurrent to trip the protection circuit.
I've seen this when a faulty aftermarket fan controller shorted 12v to 5v, it took out a CDrom, but left the rest of the system intact because it was a multi-rail supply.

Admittedly to most people it probably never makes any difference.
