I'm new to this site I wouldn't normally turn to this but for the life of me i have no idea whats happened to my pc. I built it in the summer used to play all high end games at 1440p ultra 60fps now struggles to get 30fps on 1080 whilst playing the same games. everything runs cool i just cant seem to find the problem. any information would be great! thanks in advance

LloydMartin,

It's a bit mysterious. With those components, the system should fly.

I don't know anything about Windows 10, but from a Windows 7 perspective, I would think the possibilities are:

1. Malware /Virus- run Malwarebytes and your own anti-virus complete scans

2. Very full C:\ drive partition. Is this an SSD or mechanical HD?

3. A Windows update that changed settings.
__A. Check that the Power Option mode is "High Performance". A Windows 7 update once changed the power options on my GHP z420 and the CPU was running at 50%! I thought the CPU had lost two cores.
__B. Disable hiberation for the CPU and monitor. On some Windows 7 this apparently causes accumulated errors. Some systems get digital sleeping system and never wake up,...

4. Check in BIOS on the that multi-core and hyperthreading are enabled and the drives are in the correct mode AHCI or one of the RAID modes.

5. Disable all display enhancements- in Windows 7 the Aero and transparency features reduce performance.
_______________________________
Some of these items are general ways to improve performance but the key feature is that it ran well at first, but doesn't now, so the focus should be on what is different.

If none of these items or you own investigation helps, you might- as painful as it is- consider wiping the HD and doing a careful reloading of the OS and programs.

Let us know what you find out.

I have had 1 or two power cuts but I haven't unplugged it physically. the psu is EVEGA supernova 750w GOLD.

You my friend are a lifesaver!!!

for some reason power saving mode was in balanced and had my processor set to minimum 5% maximum 5% so i have now changed both to 100%. is this safe? and again thanks a lot!

LloydMartin,

You seem to have been methodical in analyzing the situation and no reason has really popped out of the mix of ideas that have been discussed.

If it wouldn't be too much trouble, if you would install the free trial of Passmark Performance Test, it's possible to learn a lot about a system by comparing to others that are nearly identical. There are currently 1552 tests of i7-4790K /GTX 980 systems and I'm quite sure there will be several using the same motherboard and drives.

This is how it can help:

The top rated i7-4790K /GTX 980 system:

Rating = 7768.3 / CPU = 13914 () (O/C to 5.0GHz on ASUS Maximus VII Hero) / 2D = 1349 / 3D = 13906 (2X GTX 980 in SLI?) / Mem = 3682 (32GB) / Disk = 13487 (Kingston SHPM2280P2H 240GB)

Usefully, the owner also tested with a (pair?) of GTX 980 Ti and increased the overclock to 5.2GHz:

Rating = 8117.8 / CPU = 14207 (O/C to 5.2GHz) / 2D = 1434 / 3D = 15398 (in the Wow! category) / Mem = 3739 (32GB) / Disk = 14567

Both these systems are performing ell enough to be in the Top 100 of (I think) about 16,000 system tested. The i7-4970K is a really good one as are the ASUS Maximus and GTX 980.

By contrast, there are 201 systems with the same CPU /motherboard / GPU configuration and the lowest scoring is:

Rating = 3134.8 / CPU = 11477 (4.4GHz) / 2D = 1211 / 3D = 11138 (still great) / Mem = 2349 (8GB) / Disk = 715 (WDC WD6400AAK)

Amazingly, with all the other great choices, that system has an 500GB SATA II mechanical HD and the test results tell the sad story clearly.

So, by having so many systems to compare with, problems may make themselves clear. On Passmark, the median CPU score for the i7-4790K is 11127, so if your system is running significantly below that, it's the CPU. And the story is the same for the RAM, memory and disk as they can all be compared to the best, averages, and worst.

Cheers,

BambiBoom

LloydMartin,

It's very satisfying when the problem that seems serious is a setting. You may have been the victim of the same Windows update that reset my performance setting to "balanced".

As Windows 7 doesn't have the variable setting for CPU use apparently in Windows 10, I'm not sure what are the implications of running 100 /100% setting. The i7's of course have a base clock speed and "Turbo" because not all uses demand the highest clock speed.

I'd say try the 100% setting but run the temperature monitor on top all the time in all the uses until it's clear that the setting doesn't create a thermal problem. It may be that a 100% setting is like running the system under a full stress test even when only checking email.

It appears that my last post describing the uses of Passrak Perormance Test crossed yours. As that test would have revealed the CPU under-performance, on a system with such high potential as yours, I still it would be worthwhile to use it.

Besides identifying problems, it's also good to evaluate upgrades. I bought a Dell Precision for $52:

Precision T3500 (2009) (Original) Xeon W3530 4-core @ 2.8 /3.06GHz > 4GB (2X 2GB) DDR3-1333 ECC > 9800 GT > WD Black 500GB
[[Passmark system rating = 1963, CPU = 4482 / 2D= 609 / 3D=805 / Mem= 1409 / Disk=1048]

> and used Passmark scores to see what hardware produces the best scores. then checking the cost, I spent $60 on a CPU and $43 on RA<. plus reused a GPU and drives I has sitting around. The $185 system:

Precision T3500 (2011) (Rev 2) Xeon X5677 4-core @ 3.47 /3.73GHz > 12GB (6X 2GB) DDR3-1333 ECC > Quadro 4000 (2GB) > PERC 6/i +Seagate 300GB 15K SAS ST3300657SS + WD Black 500GB > 525W PSU> Windows 7 Professional 64-bit > 2X Dell 19" LCD
[Passmark system rating = 2751, CPU = 7236 / 2D= 658 / 3D=2020 / Mem= 1875 / Disk=1221]

With the value of the stock part I had added, it's really about a $350 system, but study of the other tested T3500's produces a really good result form the cost /performance view.

Cheers,

BambiBoom
