I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Does anyone here actually have, or know someone who has, one of these computers?
It sounds like a good buy (WalMart), and I read the various reviews but of course I have no way of knowing if they are real/true or not.
The sealed liquid cooling, does that mean no maintenance ever?
I do not normally do a lot of internal work/replacement other than upgrading video cards and so the limited upgrades would probably not bother me very much.

Hi,

I'm buying a new computer with Vista home premium (32 bit), and I can't decide whether I should get a 2.4 quad core or a faster dual core (since it's cheaper).

I've searched about this but all the results I've got were from 2007, so I'm not sure if things changed much now.

So what do you think? will I benefit from the additional cores? or shall I go with faster dual cores?
appreciate your help

I did a check today on my computer because its been running slower than I thought it would when I bought it. When I ran the test it said I have 1 core working, and that the processor is at 2.36 GHz, not the 2.66 it should be at. I don't know why only 1 of the cores is working, so I was hoping one of u tech guys out there might know... Can anyone help?

Ok, I'm building a CPU and I'm stuck between Intel's Core 2 Duo E8500 and their Core 2 Quad Q9300. I was going to go for the quad-core, but I heard things about how apps still aren't optimized for four cores. I will mainly be gaming, occasionally using photoshop and flash.

My problem is
a) I want games and apps to run good today
b) I want have a solid CPU that will give me excellent performance for the next 2-3 years.

What's the techguy.org consensus? I have to go with Intel as I already bought a mobo, and $270 is my absolute price maximum for a processor.

Hi guys. I've been looking at 2 laptops, they are basically identical but one has an Intel Core i3-4005U mobile processor and 4GB of RAM, and the other one has an AMD A4-5000 mobile processor and 6GB RAM. The guy at the store and a couple other people I know told me that the Core i3 is better than the A4 as the AMD "Quad Core" processors aren't very good, so even though the Intel i3 is only dual core it will be better than the quad core AMD. The other question is the RAM. Is 6GB that much better than 4GB or will 4GB be fine for basic use. (That's all this laptop is for. Basic use and touch apps since it will be touchscreen)

The AMD laptop is this one: Buy the HP Pavilion Notebook - AMD A4, 6GB, 15.6 at TigerDirect.ca
And the Intel here: Buy the HP TouchSmart 15.6 Notebook PC - F5W37UA#ABL at TigerDirect.ca

Last question, what the hell is DDR3L? All the new laptops have it nowadays... Is it backward compatible with normal DDR3 laptop RAM? Meaning can I take a normal laptop DDR3 4GB stick out of my dads laptop and put it into the 4GB (i3) laptop if thats the one i'm gonna get? Or does the DDR3 "L" part cause issues?
Thanks

Edit: Sorry i'm not sure if this is the right place for this thread. If it isn't mods could you please move it? Thanks

A:AMD A4-5000 "Quad Core" vs Intel Core i3-4005U Dual Core

Hmm, I guess you should read some reviews. But just from the specs the AMD has 6 GB ram instead of 4. Has a DVD burner where the Intel shows no optical drive. It only has W8 8.0 where the Intel has 8.1. But some people may prefer 8.0.

Read reviews. See how each performs. If you don't wish to use it to burn DVD then the optical drive, or lack thereof may not matter to you.

Edit: Oh, and the AMD is about $80 cheaper.

Can i replace the CPU to a Quad Core without changing the cooling system?

Your spare 500W power supply likely DOES NOT HAVE sufficient 3.3v/5v power and therefore will not work.  If you do not use the performance copper heatsink it will work but the fan will be running all the time.   The Copper heatpipe heatsink is the same as the GX620 heatsink. HEATSINK D9729  SHROUD J9761

Hi,
I have two laptops made by the same manufacturer and same year, but one is a dual core laptop with an SSD harddrive and the other is a quad core laptop with a regular hard drive. Both laptops run Windows 8.

I would like to transfer my programs and files from the dual core to the quad core. However, obviously the quad core has different hardware.

I am wondering if I simply remove the SSD from the dual core and put it into the quad core (replacing the quad's primary hard drive with the SSD) and simply boot up the quad core, would that be sufficient? Will the quad core recognize the hardware mismatch and automatically correct the drivers, while keeping my programs and files?

Or is there some other, efficient way to make the transfer? I really want to avoid having to reinstall all my programs.

Thank you

A:Transfer programs and files from Dual Core to Quad Core

There are a lot of third party tools designed to move a Windows installation to new hardware. I prefer using native Windows tool Sysprep for this, mainly because the method is the one and only Microsoft supports and recommends but also because it has never failed me.

The method is described in this tutorial on our sister site the Seven Forums and works also with Windows 8: Windows 7 Installation - Transfer to a New Computer - Windows 7 Help Forums. Method One in tutorial would be ideal for you for moving the SSD to new computer.

Read the information and warnings in the beginning of the tutorial carefully, especially the warning about Windows needing to be reactivated is important. Come back if you have any questions.

I have a xigmatek rifle cpu cooler on a quad core q9550 processor , and I am wondering what should my core temps be?

Coretemp is showing (at idle)-
core0 - 49 C
core1 - 46 C
core2 - 45 C
core3 - 55 C

Why is core3 so much higher? Is it possible the thermal compound above the core3 is not as spread out as it is on the other cores? I used arctic silver 5 and followed the instructions to put the compound on as a single line across the cores of the cpu.
Also, I have speedfan 4.34, and for some reason it reports different core temperatures
core0 - 42 C
core1 - 42 C
core2- 40 C
core3 - 51 C

Also, what is the "internal temp" and "remote temp" that speedfan reports. It also seems to have confused the CPU with "System" as CPU is showing 23 C and System 37 C.
Lastly, my video card, ATI HD4870 seems to run so hot!
temps at IDLE are
GPU temp - 77C
GPU Load 0%
Fan Sped 1288 RPM
GPU Temp (DISPIO) 77.5
GPU TEMP (MEMIO) 86 C

I am looking to build my own PC as I can't afford £1,000+ to get someone to make one for me, I will be using it for gaming and communication and a little college work, I will probably be using Bullguard to protect it and OpenOffice instead of Microsoft Office with a Win 7 64bit OS.

Bearing this in mind what would be the best Processor for the Intel Core i5 3.4 GHz Quad-Core (BX80637I53570K) Processor and what would be the maximum Memory and Storage I could attach to it? ( I preferably want 8GB of Memory and 1tb of storage ) but I can be flexible.
 

A:What would be the best motherboard for a Intel Core i5 3.4 GHz Quad-Core (BX80637I53570K) Processor?

The CPU you want is the i5 3570K. That runs on the socket LGA 1155. When you are on a budget, any mid range mobo will suit your needs. Use the savings from the mobo towards a better HDD or even an SSD. You will also need a GPU.

I would recommend the ASUS P8Z77-V LK motherboard. As for RAM, 8GB is enough. As for the HDD, 1TB is great. I recommend the WD Caviar Black 1TB HDD.

Make sure you can get in a GPU.

Hi,

about 2 years ago I have upgraded my computer with a new motherboard, rams and a processor and since we moved in between I cannot find the boxes or bills from that time.

The problem:
I am 90 percent sure, that at the time I wanted a quad core processor and my computer properties say that I have Intel Core i5-3450.
I googled around and all retailers as well as Intel list this processor as quad, but I whenever I use aplications where cores are displayed (i.e. playclaw or some kind of benchmarking), it only ever shows core 0 and core 1.
When I go to task manager > processes > and go to select affinity on a random process, once again only 2 cores are aviable to choose from.

Any ideas what might be causing this? Because if I am not mistaken I have had my computer on a leash for 2 years...

I'm having an issue with my CPU. It seems that it is only using one of its cores. This issue first became apparent to me when I was trying to run Blacklight Retribution. It popped up a warning message saying that my computer does not meet the minimum requirements of have at least a dual core. And indeed the game was unplayable, with single digit fps constantly.

However when i go to the performance tab of my task manager it shows 4 graphs, meaning that 4 cores must be running. Then I go the boot tab of my systems configuration, click on advanced options and underneath the "Number of Processors:" check box (which is unchecked), it shows 1 as the number of processors.

My processor is an Intel(R) Xeon(TM) CPU 3.60GHz (4 CPUs), ~3.6GHz.

I started buying the parts yesterday with the case and motherboard. I picked up an Antec Nine Hundred case and an ASUS P5KC motherboard. This board will support either the core 2 duo or core 2 quad chip and has slots for 4 ddr2 dimms and 2 ddr3. So here's what I'm thinking for the rest:

Antec TP3-550 PSU (550W)
Western Digital 750GB HDD
EVGA 512 MB Video PCI-E

Question: Should I go with the Core2 Duo at 3.06 GHz or the Core 2 Quad at 2.4? In either case I can get either 2GB DDR3 at 1333 MHz or 4GB DDR2 at 1066 MHz for roughly the same price. With the DDR3 the memory would be maxed out because there are only two DDR3 slots and I can't find 2GB DDR3 dimms that I can afford.

Edit: I picked out a Zalman cooler because I have one in my current PC and when I installed it it cut the idle temp on the CPU by 12 degrees but the case has a side vent and room for a 120mm fan. Should I get the cooler or stick with the stock HSF and install the side fan? This case is loaded with fans already - two 120mm in front pushing through the drive bays, 1 120mm exhaust fan at the top rear of the case and a 200mm on top. I think the 550W PSU will handle that and more.

i have a Intel E5400 Overclocked to 3.23GHz and was going to upgrade to a Q9400 quad and was wondering as i mainly use my PC for high end gaming is quad core as important as it is used more for multitasking and i was told dual would be better for gaming is this true?

A:What is better for PC gaming Dual Core or Quad Core?

It's a little confusing. I'd say in general, quad-core processors are more powerful than dual core; however, that doesn't necessarily mean faster.

Certain programs are written to take advantage of multi-core processors, like many games and power-hungry programs such as Photoshop.

However, not all are. Windows does its best to distribute the load evenly, but it's not the same.

Furthermore, many quad core processors are clocked at a lower rate than dual core. Your dual-core processor is clocked at 3.23GHz; the quad is clocked at 2.66.

Bottom line: if the programs you will be running can make use of all the cores, you will very likely see a performance increase. If they are not designed that way, there is a good chance your performance will actually decrease.

In your case, I suspect the programs you will be running can make use of the 4 cores well; many games do. But use your judgment!

Everything is installed properly, the cpu heatsink/fan is fitted correctly (thermal paste etc applied). Fan is plugged in properly and spins while trying to boot. Everything works as per normal but the computer wont Post or load anything at all with the q9550 installed.

Like i said earlier i simply put the e4500 back in and the computer loaded perfectly fine.

the motherboard booklet isn't very helpful, it shows you how to physically "install" the cpu but doesnt tell you what you should do when upgrading from a dual core to a quad. It shows you how to clear the CMOS but doesnt tell you "when" of "if" you need to. Do i need to... Read more

A:Upgrading from Core 2 Duo to Quad Core won't Post

You have tried clearing CMOS ? Install the CPU then clear.
If that doesn't work then you're probably right in assuming you have a DOA CPU.

Hi all! I am not computer illiterate. I have a question for you. I am switcing from an AMD dual core 2.4GHz to a Phenom 9750 Quad core. Changing out the heatsink and fan also. Can I just swap out the CPU's and restart Windows 7 Ultimate 64bit. Or do I have to do a complete reinstall of the same OS? I know that I changed MOBO's or something like that, I would have to reinstall. But I'm not sure about the processors. Any answers would be appreciated. Thanks a bunch in advance!

A:Upgrading from a dual core to a quad core!

I swapped out my friends Intel E6400 Conroe for a Q9550 last week and everything was fine and runs great.
I don't see why AMD wouldn't be the same.

First, some keywords to help searchers:

QX9650, quad core, task manager, cpu-z, cpu-id, shows showing only 2 two cores.

I recently upgraded an Intel E8500 to a QX9650 and had the problem of Windows 7 only showing 2 of the 4 cores.

It took a few frustrating hours to find the solution, but I got there in the end without the need for a Windows re-install. I hope that this little post may help others to resolve the problem quicker than I.

1st: You must have Windows 7 Professional. Home Premium does not support more than 2 cores. Upgrade to Pro.

2nd: If Task manager and CPU-Z are only showing 2 cores, you'll be feeling pretty confused, right?

Go to Start-->Run, type MSCONFIG.
Under the BOOT tab, click 'Advanced Options'.
In the top left corner it says "Number of Processors" (you'll have been here already and it says '2').

Uncheck this and do a reboot.

This solved my hours of confusion. Now I have 4 cores in Task Manager, CPU-Z and all is well.

If all this fails, then get yourself set up for an OS reinstall; that should get you where you want to be.

I hope this helps folks a little as I had a hard time resolving this quickly.

I'm no expert but my sketchy understanding is that if you tell Windows you have no processors, it re-evaluates this at boot and discovers that you've changed from a 2 core to a 4 core.

Well, it worked for me and I hope it helps others out there.

Jove.

Hi all,
HELP!
My quad-core processor is only running 1 core. I have scrawled the web for fixed and such, but I'm having no luck . Here are some images from my device manager, and CPU-Z for proof, and the problem.

http://www.imgdash.com/uploads/20049_1core.JPG

http://www.imgdash.com/uploads/4c522_1core2.JPG
As you can see, my device manager doesn't even show any processors, and only shows my computer as a Standard PC. And on the CPU-Z, at the bottom, it only shows that i'm running 1 core! (Also the same on task manager)

All chipset drivers etc were installed.

I've tried a few things, optimizing my bios and such, but im abit of a novice when it comes to the bios.

Please help, and anything you would like to know, I will be glad to be of assistance!

Thanks for your time

with Intel having a price crash on the 22nd of july i am torn where to go to build a friends new rig!! they want a decent gaming rig in order to play crysis flat out but on a bit of a budget of £1200...

so would it be best for me to build using an intel quad core intel Q6600, which will cost the same as the top end dual core Intel Core 2 Duo E6850...(around £130-180 after the price crash)

then the question is ddr3 or stick with low latency ddr2

and which graphics card to go for thats around £200 mark...i was thinking the foxconn geforce 8800 gts...

Which is better for playing games?
A 2.4Ghz Quad Core Processor
or a 3Ghz Dual Core Processor?

I opted for the quad core on the assumption that more cores was better, but this doesn''t seem to be the case.

To what extent should I regret my decision?

My Dell E6400 laptop is still working perfectly now with a Crucial 512 GIG SSD and a harddisk cradle  with a hybrid 512 GIG harddisk. With 4 gig of ddr2 memory this dual core machine is as fast as a quad core HP 6550 with ddr3 and the same disk setup crucial + hybrid.A Windows 10 update started at the same time and when the HP is on 95% the Dell is on 90%. I would expect a quad core and ddr3 to outperform the E6400, but is does not. Is Windows update just using 2 cores on both machines or what else could cause this small difference?

A:Why does a Quad core not perform better then a duo core?

The update installation will be drive-limited -- not CPU limited.
For applications that use the extra cores, the quad core will be faster -- for others, not.

Basically i'm not a computer expert I know the basic/intermediate knowledge of a computer and would like some tips. Im into my gaming, not very competitive gaming so none of the popular CoD games and such but games such as WoW, WarRock, RisingForceOnline and such others but I came across a dilemma. What would be better for gaming, a quad core processor, or a dual core processor. The processor's I speak of are the

AMD ATHLON II X4 635 AM3 Quad Core Processor 4 x 2.9Ghz

And the

AMD Athlon II X2 Dual Core 255 3.10GHz

I'm a bit unsure of how this all works out because the quad core has 4 x 2.9Ghz processors therfore a total of 11.6Ghz, and the Dual core would equal 6.2Ghz. Could some explain to me how all of this works and which would be better for my situation?

Thankyou

Mike
 

A:Quad core vs Dual core

First, the quad-core has 4 2.9GHz processors equal to 4 2.9GHz processors. They are not accumulative. Don't mistake this.

The average Windows program is written for one processor. That program will use one processor, regardless of how many you have in your system. Windows is not like Linux. The operating system doesn't control processor use, the individual programs do.

WoW has been optimized for use with multiple processors. But it hasn't been written from the ground up to support them.

In WoW's case, you will see better performance on the dual-core listed than the quad-core, provided you are not doing anything else on the computer at the time.

In short, multiple processors optimize using multiple programs (that actually use the processor in the first place). They don't optimize the speed of a single process. Don't add up processors for speed. It doesn't work that way.

Looks like both laptops are the same, except the AMD is a quad, as all AMDs seem to be. Is there really a speed difference since they are both 2.2GHZ? Or is AMD a better value than Intel?

Looks like the Intel Cpu is better than the Amd according to this :- http://www.cpubenchmark.net/compare.php?cmp[]=2440&cmp[]=2537

A major difference between those 2 laptops is the "ToshibaC55DT-C5245 15.6" Multi-Touch Notebook (Black)" has a touch screen but the "ASUS15.6" R556LA Notebook" does not.

Also the Toshiba has a DVD writer built-in and the Asus does not.

EDIT : if you're thinking of buying a new laptop why limit the choice to those 2 ?

Got an AMD 9850 Quad ran Everest Home which indicates core 1 running 2397 and cores 2,3, and four at 2500. Anyone have any idea what could be the problem? Just got this yesterday as barebone, new parts ASUS MA3A 76-CM mobo, 4GB Kingston Hyper PC8500. I have updated the mobo, used Prime 95 and Orthos test and system passed after 2 hours on each test. Any ideas, suggestions or fixes available?
 

A:Solved: AMD Quad 1 Bad core

Not sure if thats really a bad core. AMDs can turn off certain cores. Looks more like a software issue.

If you are able to return the CPU, get a PhenomII CPU instead.

For gaming and most operations, that X3 runs cooler and faster.

My pc has a quad core cpu but if i look at the performance tab of task manager there`s only one large white box showing activity. Some places are saying that there should be 4 boxes for a quad core cpu and some are saying not. Under boot options it states 1 processor and again some places are saying to leave this alone and some are saying to change it to 4.
Does anyone have a definitive answer on this and what settings they should be?

please see my screenshots
1. If you look again at task manager does it list as indicated on my arrow - cores
2. On Task manager click open resource monitor - now see my second screenshot
3. You should NOT change the processors on boot options, just as you should not change the max mem both of those are for testing purposes only -

Hello, Thanks for reading this.
Dell E520
Q6700 2.6 Ghz
4 Gig Ram
9500 GT Video Card
Hitachi 1 TB HD
Windows 7 64 Bit
The first thing i did was check to make sure i had the right bios, after installing the quad core was to check if windows recognized it, went to system and it says "intel core 2 quad".
So then i downloaded real temp to make sure my processor wasnt over heating (didnt buy the fan upgrade) and it shows 2 cores. The performance increase is noticeable but i did go from 1.8Ghz to 2.6. Temps are running between 40C and 60c at a load.
Then I started wondering is this a dual core so i checked in task manager and it also shows core 0 and core 1 (2 cores ).
Intel says the bios supports quad core technology. So did I do something wrong? or is this a dual core with 4 cores? <<<That sure sounds dumb...

I've come across a weird problem with my quad core, the problem is whenever I turn the computer on it will either boot up for a while and shut down and reboot (doing this many times until it decides to work). I've already done a repair install with no avail at all.

I've had this computer for about two months and I've got no other problems with it at all, is there anything I can do, greatly appreciated

Hello,
Recently I've dig into my basement and found an old computer (about 2008). It has an LGA 775 and there's a Pentium D currently installed inside. Problem is, I want to upgrade, to a better CPU, and I fortunately have one.however, once I do, the Computer fails to start. Even the mobo Is failing to Post. After that, I took out the better CPU ( which was a core 2 quad by the way) and replaced it with the old one. Funny thing is, it runs normally again. I have no idea why. I have tried the Core 2 Quad on another different computer which I borrowed from a friend. It runs fine...

Heres the barebone specs of the old computer I'm trying to upgrade.

Pentium D 3.4Ghz
[Updated] (Mobo make and model included in the picture attached)
2 GB (DDR2) ram
HDD 160GB (With Ubuntu)
Aztec Earth Watts 500W powersupply

Greatly appreciated if someone can help me.
