Just upgraded my CPU and I need help.

Hi guys! I'm just here looking for help. I have a a6400f HP Pavilion upgraded to 4GB of RAM and an nVidia 9800GTX. The rig really wasn't anything special back in 2008 and it really isn't anything special in 2013. However, I don't have the funds to invest in a new computer and would like to try to push this thing to max for the lowest cost possible.

The processor that came in the box was an Intel e2200 Dual Core with 1M L2 cache. After looking around I decided to purchase an Intel q6600 Core 2 Quad processor used (I know it's not the most reliable thing to buy but $50 is a helluva lot cheaper than $150 when you're pinching pennies) off of Amazon. I got it in the mail today and decided to install the processor, using my old heat sync and some new thermal paste.

The install went smoothly and the computer booted just fine but when I tried to do any kind of CPU intensive task (opening programs, installing software or opening new web pages) my computer would hang and take a considerable amount of time longer than what it would have with the e2200.

I decided to do a benchmark test, using the Final Fantasy XIV benchmark tool. The first moments of the benchmark performed considerably better than before I had installed the new processor but after about 30 seconds my entire system crashed. This immediately threw up alarms and I installed a program that monitored my temp. I was getting high 40s' - low 50s' even during the benchmark.

After doing a bit of research, I saw that it was recommended to upgrade your BIOS to their latest version and do a CMOS reset. I did both of these things, booted into safe mode and restarted my computer. None of these worked and I continued to be greeted by a sluggish computer and a system crash during the FFXIV benchmark.

Now, I've come to several possible hypotheses...

#1. Incompatible CPU/Mobo. While the socket matches fine and I would assume the processor should work fine, after reading about several other individuals upgrading their a6400f with a q6600. I can't find any official documentation that states the CPU/Mobo are entirely compatible.

#2. Overheating. While I ran the temperature app during the benchmark without any spikes in degrees, I think I would have to be a fool to completely discount the possibility of an immediate spike in temperature after not upgrading the heat sync.

#3. Crummy CPU. Since I bought the thing used from Amazon, it's not too unlikely the processor itself is garbage.

#4. My PSU isn't powerful enough. I checked around on this one and couldn't find anyone recommending this as a solution, in the past, to people with similar problems. I'm currently sporting a 250 W power supply which probably needs to be upgraded regardless of being the source of my frustrations or not. This would explain why the FFXIV benchmark crashes but I don't know if it explains the poor performance outside it. I really hope this is the issue because upgrading would be relatively cheap and I wouldn't be completely screwed over.

Please, if anyone has any possible solutions or insight into my problem, let me know! Thanks a bunch in advance!

Good God man! Why would you do that!

Yes, oh yes, your crappy, made by the lowest bidder psu is most certainly to blame.

A cheap 250w would only output 200w max, which your motherboard and hdds would take alone... Now it's not as simple as just wacking a new psu into this bad boy and opening the throttle. No sir-y.

Chances are likely it's a proprietary psu, best to unscrew it and compare the screw holes to an existing atx specified psu, as the screw holes may not line up, even if it's the right shape!

Even then, make sure you also check the actual motherboard connector too. It would not be beyond the realms of possibility that that too is a proprietary connector.

So to answer your question, good buy, the q6600 will inject some...

Could be the PSU I mean thats low power even back then but the PC is more likely to crash than run slow if its a power issue. As for a rubbish CPU I always thought the q6600 was better have you checked the serial number on the CPU? Your system is not set to flip if the CPU hits 50c or something just a thought. According to intel the use the same socket type so I would say that unless it is a power issue blame the drivers. Are you using drivers off the web or off a CD?

Thanks for the heads up on the PSU screw holes... But do you really think the PSU could be responsible for the general sluggishness?

yes.

I just used this and found you minimum need 160w recommended 220w for the e2200

with the q6600 it jumps up to 190 minimum, 240w recommended. That's only 1hdd, 3 usb devices and onboard graphics..

So coupled with a cheap, pretty average psu to begin with, age it by 5 years, and yours would absolute not be able to output anything near 240W!

I mean, it's enough to boot, but anything taxing and the figures don't lie, your psu can't keep up.

I'm gona guess that you first shot was aimed above me I hope;) good answer though I tend to replace a PSU every 3-4 years unless its a Seasonic platinum rated or something. So what are we saying 300w PSU minimum?
