Is my old mobile i5 dying?

Hey guys. I have an issue with an old laptop (HP Pavilion dv6). It was running some undemanding games like it was usually running them in the beginning, but this summer suddenly something went wrong. I thought it was GPU (mobile Radeon 5650) that was overheating\failing. So I cracked the sucker up, cleaned it, changed thermal paste, but things were not getting any better. It's not so hot anymore though, but I just can't play games anymore. None of them. I noticed that WEI rating for cpu is lower than it was. So I tried to test my cpu - i5-450m. Results: WEI for cpu is 5,7 (notebookcheck.net score is between 6,5 and 6,8). Okay so I downloaded Intel Processor Diagnostic Tool. The test failed at CPU frequency time check several times in a row, but succeeded after awhile. Then I got really sad and ran CinebenchR10 64bit and the score was 2023 @ single CPU and 3426 @ multi cpu render test. Notebookcheck.net scores were like over 3000 @ single and over 7000 @ multi cpu test. So my old mobile cpu is dying. Am I right??

I'm not so sure if it's the cpu or the mainboard\socket which is failing. Should I replace the cpu?
Thank you!

CPU's don't die in the manner described so no, it's not the CPU itself.

If the CPU was failing you'd simply get crashes and/or data corruption.

It's either a cooling issue which is forcing the CPU and/or GPU to throttle or a software issue.

Unfortunately I can't think of a simple test. The only things I can think of offhand are:

1) Find out the CPU and GPU throttle temp and monitor temp while gaming (i.e. "core temp" for CPU), and/or

2) Get a spare drive and install Windows from scratch, including drivers from AMD (not the laptop site), and/or

3) Benchmark:
a) Run 3DMark2001 benchmark (easy to find) and write down the score, then
b) Install or reinstall the video drivers from your LAPTOP site and repeat the benchmark and write down score, then
c) attempt to install the video drivers from AMD direct which should be newer. May not work as many laptop makers modify Windows to prevent this as they modify the video drivers to support laptop shortcuts.

*I got a higher benchmark score by installing a standard copy of Windows OEM (not made by laptop manufacturer) then installing drivers direct from NVidia which were newer. My score was 35% higher!

Check my above comment. Please note that LOWER performance is generally not a failed component unless it's a fan.

Failed hardware generally just causes crashing, freezes etc.

Thank you for the suggestion. I was getting freezes before I changed the thermal paste. Then I swaped hdd (borrowed from my dads HP) and did a fresh OS install and downloaded the latest drivers from the manufacturers websites. Didn't helped much... Did some testing with League of Legends: changing resolutions, going from lowest to highest detail setings and stuff - nothing was really helping. 30fps at most and going as low as 3-5dps. Then stuttering and crashing. It's even worse when I have no idea what the hell is up with that thing.

Just ran the CinebenchR10 in my balcony (It's freezing cold out there, below zero celcius) and it did quite good:
3044 @ single (2023 yesterday)
6625 @ multi (3426 yesterday)

It's overheating. Sorry for the time wasted :)

Not a waste of time, however it probably means your FAN is the problem as I suggested above.
